Amino acid fertilizer is an organic and inorganic complex formed by combining plant amino acids as a matrix, using its huge surface activity and adsorption retention capacity to add nutrients required for plant growth and development (nitrogen, phosphorus, potassium, iron, copper, manganese, zinc, aluminum, boron, etc.) through complexation and chelation. This fertilizer can not only maintain the slow release and full utilization of macroelements, but also ensure the stability and long-term effect of trace elements. It has a good effect of enhancing plant respiration, improving plant oxidation-reduction process, and promoting plant metabolism.
Effects of amino acids on crop development
- Early germination and high germination rate
The application of amino acid humic acid can accelerate seed germination and increase germination rate, which is particularly significant in early spring and low temperature (generally germination can be advanced 1 to 3 days, and the germination rate is increased by 10 to 30%).
- Well-developed root system and strong absorption capacity
Amino acids have a special promoting effect on the root development of crops. Many agricultural scientists call amino acids “root fertilizers”. The main effect on the root system is to stimulate the division and growth of root meristem cells, so that seedlings can take root quickly, increase secondary roots, increase root volume, and elongate the root system, which ultimately leads to a greatly enhanced ability of crops to absorb water and nutrients.
- Effect on the growth of aboveground vegetative bodies
On the basis of sufficient nutrient supply, the stimulation of amino acids can make the aboveground vegetative bodies of plants grow vigorously, which is manifested in plant height, stem thickness, number of leaves, dry matter accumulation, etc.
- Effect on yield and composition factors
Amino acids have different effects on the yield and composition factors of different crops. For grain crops, more ears, more grains, and 1,000-grain weight play a role in increasing yield. In the early stage, they have good effects on tillering and reducing the empty and barren rate. Effects of amino acids on crop physiological metabolism and enzyme activity
After amino acids enter the plant body, they stimulate the plant, mainly manifested in the increase of respiration intensity, photosynthesis, and the enhancement of various enzyme activities, so that the fruit can be colored and matured in advance, and high yield and output value can be achieved.
Amino acid fertilizers can promote photosynthesis and the formation of chlorophyll, and have a significant promoting and activating effect on physiological and biochemical processes such as oxide activity, enzyme activity, seed germination, nutrient absorption, and root growth and development. In particular, its affinity with plants is unmatched by any other substance. The efficacy of amino acid fertilizers combines the long-term effect of organic fertilizers, the quick effect of chemical fertilizers, the stable effect of biological fertilizers, and the enhancement of micro-fertilizers. Here we mainly discuss the application of amino acids in this fertilizer in agriculture.
