With the continuous development of science, more and more new products have been developed and applied in modern production. Amino acid water-soluble fertilizer has been trusted by the majority of users since it was introduced into the market, and has become the first choice of fertilizer for many farmers. The following is the use method of several amino acid water-soluble fertilizers provided by the manufacturer of amino acid raw powder. 1. Soil irrigation when the soil is watered or irrigated, as long as the water-soluble fertilizer containing amino acids is mixed in the irrigation water, the plant roots can be fully exposed to the fertilizer. 2. Foliar fertilization dilutes and dissolves amino acid water-soluble fertilizer in water and then sprays it on the foliar surface, or sprays it on the foliar surface together with non alkaline pesticides (most commonly used pesticides are non alkaline) in water, which can greatly improve the efficiency of fertilizer absorption and utilization of crops. At the same time, it can also save the transportation time of crop nutrient elements in plants and achieve faster results.? 3. Drip irrigation, sprinkler irrigation and soilless cultivation Large scale planting farms, or areas with shortage of water resources, as well as high-quality and high value-added cash crop plantations, can use drip irrigation, sprinkler irrigation and soilless planting. When watering and fertilizing, the amino acid water-soluble fertilizer is dissolved in the water, which not only replenishes the water of crops, but also provides nutrients necessary for crop growth. It really realizes the "integration of water and fertilizer", which not only saves water, fertilizer and labor.

Wheat is the main body of summer grain production. Capturing a good harvest of summer wheat is the basis for increasing production throughout the year. Among them, Huang Huai wheat area is not only the dominant production area of high-quality and strong wheat, but also the frequent occurrence area of scab. In recent years, scab has occurred frequently and repeatedly, which has seriously threatened the development of China's wheat industry and the safety of rations. Since the national joint research on improved wheat varieties, the research team has focused on the major cutting-edge issues in China's main wheat production areas, guided and promoted the adjustment of the direction of China's wheat variety breeding, focused on the construction of the test platform for variety characteristics, assisted the breeding of new varieties with the application of modern breeding technology, and accelerated the renewal of green and high-quality wheat varieties. In late May, the wheat research team carried out on-site demonstration and observation of Scab Resistant, high-quality and strong gluten wheat varieties in Shandong, Anhui and other places, intensively displayed and recommended a number of green and high-quality wheat varieties, and promoted the scientific research achievements to "take root". Disease resistant varieties fight against "rotten wheat" "Wheat scab was once the main disease in the middle and lower reaches of the Yangtze River, but in recent years, due to changes in farming methods and climate, the Huang Huai wheat area has gradually become a frequent area of scab diseases." On May 21, Xu Weigang, the chief expert of the national wheat variety research group, pointed out that under the rapid development of scab, the breeding of Scab Resistant Varieties in the Huang Huai wheat region is particularly urgent. At present, wheat scab resistance breeding in the middle and lower reaches of the Yangtze River is in a leading position in China and even the world. A series of scab resistance wheat varieties such as Yangmai, Ningmai and Zhenmai have been widely used in production. "In the wheat area in the middle and lower reaches of the Yangtze River, it is in the forefront of the world in terms of breeding of disease resistant varieties, mining of disease resistant genes, and application of molecular technology. However, in the Huang Huai wheat area, which is the main wheat producing area in China, breeding parent materials with Huang Huai ecological type are very scarce." Xu Weigang said that compared with the wheat areas in the middle and lower reaches of the Yangtze River, the breeding of scab resistance in the Huang Huai wheat area seriously lags behind the market demand. Therefore, the goal of the wheat research team is very clear. By establishing the research strategy of "looking for existing promoted varieties, screening in the breeding of new lines, and creating new varieties", we will screen and cultivate a number of Scab Resistant Varieties, realize the large-scale promotion and application in the Huang Huai wheat area, and steadily improve grain production capacity. "There was no systematic identification nursery in Huang Huai wheat area before, and only Fujian and other places could be identified, but the disease pressure was too heavy, resulting in the identification of varieties' annihilation ', and it was difficult to distinguish resistance differences." Xu Weigang said that in order to solve this problem, the research team selected three identification nurseries in Nanyang, Henan, Yangzhou, Jiangsu and Lujiang, Anhui, and selected varieties from the Huang Huai wheat region as the control, appropriately relaxed the identification indicators, and "customized" the identification system for Scab Resistance in the Huang Huai wheat region, improving the level of resistance identification of breeding materials in the Huang Huai wheat region. Since the national major scientific research on improved wheat varieties was carried out, a batch of new Scab Resistant Varieties and breeding materials with the characteristics of Huang Huai ecological type have been screened out through 3930 wheat varieties (lines) and Germplasm Resources materials identified in the identification garden. Because the incidence of scab is different every year, it is not accurate to judge the resistance of varieties only through the incidence of a certain year, resulting in the "miscalculation" of the resistance grade of many existing varieties. Following the idea of "looking for existing promoted varieties", the research team searched and re identified nationwide, selected a batch of wheat varieties with moderate resistance and susceptibility to scab, including Xinong 511, Ruihua Mai 520, Zhengmai 0943, and gave full play to the driving advantages of enterprises, promoting the large-scale application of these varieties in the Huang Huai wheat region. "Molecular marker assisted selection breeding technology provides a new way for wheat scab resistance breeding." Mahongxiang, a wheat breeding expert from Jiangsu Academy of Agricultural Sciences, said that in the breeding of wheat varieties resistant to scab, "it is difficult to create disease conditions, it is difficult to inoculate in one step, and it is difficult to identify the resistance grade" are the "three major problems" in the identification of varieties resistant to scab. The high-throughput molecular marker detection platform established by the research group has greatly accelerated the breeding process of Scab Resistant Varieties in Huang Huai wheat region. In actual grain production, only one disease resistance is often difficult to meet the market demand. "In the process of disease resistance breeding, on the basis of taking scab as the main breeding goal, we should also pay attention to improving the comprehensive resistance of varieties." Kangzhensheng, academician of the Chinese Academy of engineering and professor of Northwest University of agriculture and forestry science and technology, added. It is understood that in addition to the basic "ability" of resistance to scab, the varieties participating in this exhibition often have other green and high-quality characteristics, such as Xinong 511, a strong gluten, heat-resistant and stripe rust resistant variety, Zhongmai 5051, a strong gluten and cold resistant water-saving variety, Su 4185, a cold, heat-resistant and powdery mildew resistant variety, and a series of high-quality varieties with multiple resistance, wide adaptability and good agronomic properties. "The rapid incidence of scab has brought great pressure to the prevention and control work, and the breeding of disease resistant varieties is the fundamental guarantee for the realization of green plant protection." Kang Zhensheng said, "the occurrence of scab is affected by many factors such as cultivation conditions and climatic conditions. In addition to breeding disease resistant varieties, it also needs to pool scientific research forces in plant protection, cultivation and other fields to carry out joint research." Industrialization of high-quality wheat begins with variety, and the key is "industrialization" "The noodles made by Gaoyou 2018 are of good quality, with strong wheat flavor, the stability time of Gaoyou 5766 reaching 54 minutes, and the quality index of Jimai 44 is very prominent. Konong 2009 is not only of good quality, but also has the advantage of resistance to powdery mildew, stripe rust and other diseases..." on May 22, in the 1800 Mu high-quality wheat demonstration area located in yikongqiao village, Gaoli street, Hanting District, Weifang City, The 12 high-quality strong gluten wheat varieties and 27 high-quality strong gluten germplasm resources that are representative of the Huang Huai wheat region were intensively displayed. Wheat breeding experts, representatives of flour processing enterprises and seed dealers from all over the country stopped in the field to observe and comment. With the deepening of agricultural supply side structural reform, the development of high-quality wheat has been paid more and more attention by society, breeding enterprises and breeding departments. The high-quality special-purpose wheat varieties approved by the state in 2018 increased by nearly 50% compared with three years ago, marking that China's wheat breeding research has stepped into a new stage of high yield, high quality and green on the basis of stable yield. "For the research group of improved wheat varieties, the rapid development of China's high-quality wheat industry puts forward higher requirements for the breeding of high-quality strong gluten wheat varieties." Xu Weigang, the chief expert of the national wheat variety research group, pointed out that "producing high-quality products and creating brands" is the next work direction for the development of high-quality wheat industry. "Different from the breeding of high-yield varieties, the breeding of high-quality wheat varieties should aim at regional layout, professional production, large-scale management and industrial development, and develop regional advantages into industrial advantages." Xu Weigang pointed out the key to the breeding of high-quality wheat varieties, "the research on improved varieties must not be limited to variety breeding, but also push varieties into actual production and integrate them into the development of the whole industrial chain." On the same day, at the exhibition of high-quality strong gluten wheat varieties in the Huang Huai wheat region held in Weifang, Shandong Province, the crop institute of Shandong Academy of Agricultural Sciences, Shandong Luyan Agricultural Seed Co., Ltd. and Shandong Luliang Group signed a strategic cooperation agreement on the high-quality wheat industry. Luyan company, Nanshan Group and Linyi Fumin wheat professional planting cooperative signed high-quality wheat order purchase and planting agreements respectively. This is only a microcosm of the national key achievements in tackling improved wheat varieties. Shandong Luyan Agricultural Seed Co., Ltd. has successfully implemented China's first high-quality strong gluten wheat Jinan 17 order production in cooperation with Nanshan Group since the 1990s, breaking the ice in the development dilemma of China's high-quality wheat industry. "Orders" have effectively promoted the production and industrialized management of high-quality special-purpose wheat, but there are also many problems in signing high-quality special-purpose wheat orders, among which the unstable quality and supply of wheat are the main reasons for the low performance rate. Zhouzhaoyang, general manager of the procurement department of Nanshan Group, said that due to the weather impact during the harvest, variety degradation, farmers' field management and other issues, the actual implementation rate is only 30-50% per year. What is the key to the industrialization of high-quality wheat? "The industrialization of high-quality wheat is not only the industrialization of high-quality varieties, but also the industrialization of high-quality varieties." Zhao Zhendong, a consultant of the national wheat variety research group and an academician of the Chinese Academy of engineering, pointed out that "the development of high-quality wheat industrialization begins with varieties, but the focus is on 'industrialization'." How to make high-quality varieties realize the leap of industrialization? How to solve the problem of low performance rate of order agriculture? Zhao Zhendong said that in addition to the variety itself, climate, soil and growers are the three major factors affecting the production of high-quality wheat. The construction of high-quality wheat production core base and field management technical services are important means to solve the problem of the development of China's high-quality wheat industry. "We should speed up the cultivation of a number of new high-quality wheat varieties with independent intellectual property rights to ensure the absolute safety of rations." Sunhaoqin, deputy inspector of the Department of seed industry management of the Ministry of agriculture and rural areas, said, "by holding this exhibition and evaluation, we recommend high-quality special wheat varieties to the society, meet the high-quality and efficient flour processing industry and market demand, and play an important variety support for promoting the structural reform of agricultural supply side and improving the quality and efficiency of modern agriculture."

The hydrolysis of protein waste to produce amino acid fertilizer mainly includes three steps: pretreatment of raw materials, protein hydrolysis and preparation of amino acid fertilizer. (1) Source of raw materials and pretreatment raw materials: Waste rich in amino acid components produced by refined amino acids; Animal and plant residues rich in protein, such as leather, hair, hoof armor, blood, cotton meal, soybean cake, etc. Some raw materials need to be cleaned.

Lysine and methionine are the monomeric amino acids often added in aquatic feed, because energy feed and plant protein feed are two bulk raw materials in aquatic feed, lysine is the most deficient in energy feed, and methionine is the most deficient in plant protein feed. 1. Nutritional effect of lysine: Lysine plays a very important role in maintaining the normal growth and development of aquatic animals and the normal function of nervous system. Lack of lysine in the feed will cause negative nitrogen effect (protein decomposition and excretion), so that the protein in the feed can not be fully utilized, aquatic animals grow slowly, and there will be fatty liver, bone calcification rate reduction and other symptoms. 2. Nutritional effect of methionine: Methionine is an amino acid containing * * * sulfur in essential amino acids, which is involved in the transfer of methyl in aquatic animals, the synthesis of adrenaline, choline and inositol, and the metabolism of phospholipids in the liver. Methionine can synthesize lysine, which has the function of liver protection and detoxification. Therefore, methionine can promote the growth of aquatic animals and prevent fatty liver, flower liver and other diseases.

Amino acid fertilizers produced by hydrolysis or fermentation contain a large number of small molecular organic compounds, so as a chelating agent, the development of new multifunctional fertilizers has developed rapidly. Amino acid microelements chelate Hefei. The absorption biochemical function of inorganic micro fertilizer is poor, it is easy to be fixed by soil, and there is obvious antagonism between trace elements, and the utilization rate is low, which is difficult to meet the needs of plant growth; Using EDTA, citric acid, tartaric acid, etc. as chelating agents to produce chelating micro fertilizers is very expensive. The multi-element micro fertilizer containing Mo, Zn, Cu, Fe, Mn, etc. has been prepared, which has the characteristics of resisting interference, alleviating the antagonism between metal ions, good chemical stability, easy to be absorbed and utilized by plants, and the amino acid after losing the reduction of metal ions also has nutritional effect, which is also a high-quality nitrogen fertilizer to promote plant growth. Amino acid chelated micro fertilizer is the most ideal micro fertilizer for crop growth at present, and has been used in agricultural production as a new fertilizer. At present, there are also products that combine amino acid pesticides and fertilizers, which can not only fertilize, but also kill insects and sterilize. Therefore, it is the requirement of ecological agriculture and the inevitable trend of agricultural sustainable development to systematically carry out the function research of amino acid fertilizer, give full play to the potential of amino acid, and improve its utilization rate and biological potency. Amino acid fertilizer produced by hydrolysis or fermentation is a fertilizer with compound amino acids as the main body, and contains sugar, protein or bacteria and other metal ions at the same time. Studies have shown that the fertilizer effect of mixed amino acids is greater than that of single amino acids. The fertilizer effect of some single amino acid groups with good fertilizer effect is still high, while the fertilizer effect of some amino acid groups with poor fertilizer effect is still low. It is considered that there is still a problem of optimization of amino acid composition. When protein hydrolysis or fermentation products are actually used as amino acid fertilizer, they are generally mixed amino acids, but the types and concentrations of amino acids in the waste liquid of different processes and amino acids are different. Therefore, the fertilizer efficiency of the same crop is also different, so there is also the problem of optimization. How to further optimize the composition and structure of fertilizer according to the needs of crops, adjust the proportion of each component to balance each other, and make the varieties produced diversified and specialized should be explored and tested in practice. In short, the continuous research on the hydrolysis or fermentation of agricultural waste to produce amino acid fertilizer and its application has opened up more and more new sources of raw materials, providing a new scientific basis for the scientific development and application of amino acid fertilizer. Because the raw materials and processes of amino acid fertilizer production are very different, and the components are comprehensive and complex, the production and Application Research of amino acid fertilizer is a complex system engineering, involving chemistry, chemical engineering, biochemistry, soil nutrition, plant physiology and other disciplines, which has a very broad development space.

Agriculture is the foundation of the national economy, and soil and fertilizer are the foundation of agriculture. The leading agriculture in the 21st century is ecological agriculture, and the leading food in the 21st century is green food. Green food is a pollution-free, safe, high-quality and nutritious food. Therefore, green food has strict restrictions on the growing soil, chemical fertilizers and pesticides. This requires the development of efficient and pollution-free high-quality green fertilizers to meet the growing demand for efficient agriculture. Amino acid multi-element fertilizer is a high-quality green fertilizer that meets this requirement and has high-quality plant physiological effects. Let's talk about the production of amino acid fertilizer and its effect on soil:
