After the rain, the temperature in various places will rise quickly. Although the cold wave a few days ago gave the illusion that it was "about winter", the fact is that spring is really coming. The year's plan is in spring. For farmers, this proverb is apt and true. No matter what kind of crops are being planted, spring is the most critical season. Fruit trees need to bloom and crops need to be planted. The pneumonia epidemic cannot prevent the arrival of spring plowing.

With the approach of spring plowing, the agricultural material market has gradually become lively. Various pesticide, seed, and fertilizer stores have opened one after another, with a wide variety of products, and it is quite difficult for farmers to buy. Especially for some new products, farmers' friends don't know much about it, and it's even harder to get started when buying them. Among them, amino acid-containing water-soluble fertilizers are believed to have been used by many farmers. However, it is estimated that nine out of ten farmers have the same knowledge of this fertilizer as it was when the agricultural resources pass first started. They only know it but do not know why. I only know that crops grow well with amino acid water-soluble fertilizer, but why is it good? What's the good thing? Very few people can tell. So, today, the master of agricultural resources will take everyone to get a deeper understanding of what amino acid water-soluble fertilizer is.

1. Interpretation

Amino acids are the smallest organic structure of proteins in all organisms. Multiple amino acid molecules are connected to each other to form polypeptides. Then, multiple polypeptide chains are folded into space to form proteins. At present, more than 300 kinds of natural amino acids have been discovered, among which more than 20 kinds of basic amino acids are threonine, lysine, leucine and valine. Previous studies believed that the nutrients that plants can absorb and utilize can only be inorganic, such as potassium nitrate, potassium sulfate, copper sulfate, ferrous sulfate, etc. However, the latest research has found that plant roots, stems and leaves have all amino acids Non

 Very good absorptive capacity. This is also the basis for the application of amino acid water-soluble fertilizers in agriculture.

The amino acid water-soluble fertilizer, literally, is a type of fertilizer containing amino acid molecules. From the application method, it can be divided into two categories, one is the thick type, usually washed with water; the other is the diluted type, usually used for foliar spray. Of course, the current national standards do not distinguish between these two types, and they are still collectively referred to as water-soluble fertilizers containing amino acids.

2. Raw material of amino acid water-soluble fertilizer

At present, there are two main types of amino acid water-soluble fertilizer raw materials sold on the market in my country. One is the fermentation products of soybean, soybean meal, corn bran, and peanut bran, as well as vegetable protein such as soybean products, monosodium glutamate, and wood processing scraps; The category is leather, hair, fish bone and fish meal, and slaughterhouse waste and other animal material proteins. Since plant-based amino acids are derived from plants and have the same amino acid types, they have good nutritional effects and are quickly absorbed by crops, but their biological activity is not high (that is, their regulating ability is not strong). Animal feed amino acids usually contain some active ingredients such as nucleotides, indole acid, gibberellin, etc., which can stimulate crop growth and have certain positive effects on improving crop resistance, promoting rooting, and protecting flowers and fruits.

3. The function of amino acid water-soluble fertilizer

Since the amino acid water-soluble fertilizer contains many kinds of amino acids, and different amino acids have different functions on plants, and some amino acid fertilizer products also enrich the product function by adding various middle and trace elements, therefore, the amino acid water-soluble fertilizer The functions are also multifaceted.

3.1 Promote plant growth and development

Amino acids contain carbon, nitrogen and other elements. The amino acid molecules absorbed by plants can not only perform deamination, participate in the construction of new amino acids needed by plants to form proteins, but also directly enter the tricarboxylic acid cycle to synthesize sugars Macromolecular structure such as, lipids, etc. Therefore, the reasonable supply of amino acids plays an important role in promoting the growth and development of plants. In addition, amino acids also have a certain promotion effect on photosynthesis of plants. The reason is that amino acids can increase chlorophyll content, increase stomatal conductance, and enable leaves to absorb more carbon dioxide to synthesize organic substances, thereby promoting growth.

3.2 Improve yield and quality

As the smallest molecular structure of protein, amino acids can directly participate in the synthesis of plant proteins, vitamins, and carbohydrates without photosynthesis, increasing the synthesis of plant organisms and biomass, thereby increasing crop yields And quality. In 2018, the results of experiments conducted by the Hunan Provincial Soil and Fertilizer Research Institute and Hunan Agricultural University showed that amino acid foliar fertilizers can increase the yield of cucumber, eggplant, and water spinach by 11.57%, 4.43%, and 12.41%, respectively, with a production-to-investment ratio exceeding 50: 1. The effect of increasing production and income is remarkable. At the same time, the amino acid foliar fertilizer can also significantly increase the total sugar and vitamin C content of cucumber, eggplant, and water spinach, and significantly improve the quality and taste of vegetables.

3.3 Improve crop resistance

Amino acids can improve the adaptability of crops to adverse conditions such as heavy metals, drought, flooding, high temperature, low temperature, and salt damage. The main mechanism is that amino acids can regulate carbon dioxide absorption and promote new generation in plants.

 Xie, regulate the expression of anti-stress genes, and induce the synthesis of key enzymes. In addition, some specific amino acids (such as proline) can not only actively clear out the hydroxyl-containing harmful substances produced under stress conditions, but also regulate the presence of harmful substances in plant cells.

 Organic matter content to maintain cell osmotic pressure, so that plant cells maintain normal physiological functions. Some amino acid water-soluble fertilizer products also add iron, manganese, copper, zinc and other trace elements to form amino acid complexes, and these trace elements are important catalysts in various metabolic processes in plants-components of enzymes, which have a large amount of activity. The presence of enzymes can help plants respond quickly to adversity and avoid possible damage caused by adverse conditions.

3.4 Improve soil structure

Amino acids in the soil can be used as a source of microbial nitrogen, which promotes the production of a large number of microbial flora in the roots of crops. These flora not only have the effect of activating soil nutrients, but also the secreted organic matter can improve soil physical and chemical properties and promote soil aggregates The formation of institutions can improve the soil water and fertilizer retention capacity, which is conducive to the growth of crop roots.

4. The advantages of amino acid water-soluble fertilizer

There are many types of fertilizers in the market, and the ability of amino acid water-soluble fertilizers to grow and be loved by the majority of farmers must have his advantages. From the current feedback on the use of amino acid water-soluble fertilizer in various crops and regions, and its own characteristics, the agricultural resource man believes that it has the following advantages:

4.1 Good mixability, saving labor cost

Amino acid water-soluble fertilizer can be mixed with most pesticides, fertilizers, and regulators, and the pesticide efficacy and fertilizer efficiency are better after mixing. Therefore, there is no need to separately consume artificial application in agricultural production, saving planting costs.

4.2 Good fertilizer effect, fast fertilizer effect

Some research institutions have reported that for rice, the fertilizer effect of amino acids is twice that of ammonium nitrogen fertilizer, and the various organs of the plant can directly absorb amino acids, especially after foliar spraying, the obvious effect can be seen in a short period of time. It is of great significance to grow crops, promote early fruit maturity, and shorten the planting cycle.

4.3 Multi-function and comprehensive function

Amino acid water-soluble fertilizer has a certain effect on enhancing plant metabolism, improving plant resistance to stress, improving plant photosynthetic efficiency, and increasing dry matter accumulation. It has a comprehensive function. Moreover, amino acids in crops relieve phytotoxicity and alleviate

 The outstanding performance in solving physiological diseases is also recognized by the majority of farmers.

to sum up

Amino acid water-soluble fertilizer has always been very popular in the market because of its great contribution to agricultural production. Both economic and ecological benefits are very high, which is of great benefit to the increase in crop production and income. However, the amino acid water-soluble fertilizer market is still chaotic, the raw materials are uneven, and the functionality and fertilizer efficiency are also very different.

 Often difficult. For the healthy development of the industry, there is an urgent need to formulate more detailed and strict production standards to regulate product quality and ensure the stability of amino acid fertilizer efficiency and function.
