Roles and functions of amino acids in crop growth

Different amino acids have different physiological functions on crops, but they are also synergistic. The following content is compiled based on some domestic and foreign literature and information for reference.

Alanine: increase the synthesis of chlorophyll, regulate the opening of stomata, and have a resistance to germs;

Arginine: enhances root development, is the precursor for the synthesis of endogenous plant hormone polyamines, and improves the salt stress resistance of crops;

Aspartic acid: improves seed germination, protein synthesis, and provides nitrogen for growth during stressful times;

Cysteine: Contains amino acids to maintain cell function and sulfur as an antioxidant;

Glutamic acid: reduce nitrate content in crops; improve seed germination, promote leaf photosynthesis, increase chlorophyll biosynthesis

Glycine: It has a unique effect on the photosynthesis of crops, which is beneficial to crop growth, increases the sugar content of crops, and is a natural metal chelating agent;

Histidine: regulates the opening of stomata, and provides the precursor of carbon skeleton hormone, the catalytic enzyme of cytokinin synthesis;

Isoleucine and leucine: improve resistance to salt stress, improve pollen vigor and germination, precursor substances of aroma;

Lysine: Enhances chlorophyll synthesis, increases drought tolerance;

Methionine: the precursor for the synthesis of endogenous plant hormones ethylene and polyamines;

Phenylalanine: Promote the synthesis of lignin, the precursor of anthocyanin synthesis;

Proline: increase plant tolerance to osmotic stress, improve plant stress resistance and pollen vigor;

Serine: Participate in cell tissue differentiation and promote germination;

Threonine: Improve tolerance and insect pest damage, improve humification process;

Tryptophan: a precursor for the synthesis of the endogenous hormone auxin indole acetic acid, which improves the synthesis of aromatic compounds;

Tyrosine: Increases drought tolerance, improves pollen germination;

Valine : Increases seed germination and improves crop flavor.

Nine advantages of amino acid fertilizer

1. Amino acids can promote the photosynthesis of plants

Glycine in amino acids can increase the content of chlorophyll in plants, promote the absorption and utilization of carbon dioxide by crops, increase the power for photosynthesis, and make photosynthesis more vigorous.

2. A variety of amino acids mixed nutrition effect is good

The effect of amino acid mixed fertilizer is higher than that of a single amino acid with an equal amount of nitrogen, and also higher than that of an inorganic nitrogen fertilizer with an equal amount of nitrogen. A large number of amino acids improve the utilization rate of nutrients with its superimposed effect.

3. Fast fertilizer effect

Amino acids in amino acid fertilizers can be directly absorbed by various organs of plants, passively absorbed or osmotically absorbed under photosynthesis, and obvious effects can be observed in a short period of time after use. At the same time, it can promote the early maturity of crops and shorten the growth cycle.

4. Improve crop quality

Rich amino acid species can improve the quality of crops. For example, if the protein content of grains increases by 3%, the cotton has good velvet quality and long fibers; vegetables have good palatability, pure and delicious taste, and crude fiber reduces flowers and flowers. Good storability and remarkable conversion efficiency.

5. Clean and pollution-free, improve the ecological environment

There is no residue in the fertilizer applied to the field by amino acid fertilizer, which can improve the physical and chemical properties of the soil, improve water retention and fertility, and air permeability, and play the role of conservation, maturation, and improvement of the soil.

6. Enhanced metabolic function and improved resistance to stress

After being absorbed by crops, amino acids can strengthen their physiological and biochemical functions. The crop stems are strong, the leaves are thickened, the leaf area is enlarged, and the formation and accumulation of dry matter are accelerated. The crops can mature early and because of their own vitality, they can resist cold and drought, dry and hot wind, diseases and insect pests, and lodging performance, so as to achieve stable and high yield.

7. Developed root system, strong absorption

Amino acids have a special promotion effect on the root system development of crops. Many agricultural scientists call amino acids "root fertilizer". The number of secondary roots increases, the root mass increases, and the root system elongates, which eventually leads to a greatly enhanced ability of the crop to absorb water and nutrients.

8. Effects on the growth of vegetative bodies above ground

On the basis of sufficient nutrient supply, the stimulating effect of amino acids can make the vegetative body of the aboveground part of the plant grow vigorously, which is manifested in plant height, stem diameter, number of leaves, and dry matter accumulation.

9. Effects on Yield and Composition Factors

Amino acids have different effects on the yield and composition factors of different crops. They can increase the yield of grain crops with more spikes, more grains, and 1,000-grain weight. They have good effects on tillering and reducing the empty grain rate in the early stage.

After the amino acid enters the plant body, it has a stimulating effect on the plant, which is mainly manifested in the increase of respiration intensity, photosynthesis, and the activity of various enzymes, so that the fruit can be colored and matured in advance, and high yield and output value can be achieved.
