Amino acid fertilizers contain a variety of nutrients, and it is well known that its nutrients are complete and its activity is highest. In the United States, Australia, Canada, Japan, and Taiwan, as well as in Taiwan, amino acid fertilizers have been developed and produced in large quantities. Products have long since entered the international market. The development and application of amino acid fertilizers in China will also develop rapidly in recent years.
The role and advantages of amino acid fertilizers are as follows:
1. Amino acids can promote photosynthesis in plants.
Glycine in amino acids It can increase the chlorophyll content of plants, promote the absorption and utilization of carbon dioxide by crops, increase the power for photosynthesis, and make photosynthesis more robust.
2, a variety of amino acids mixed nutrition effect is good.
Amino acid-mixed fertilizers have higher effect than isonitrogenous single amino acids, and they are also higher than isonitrogenous inorganic nitrogen fertilizers. A large number of amino acids increase the utilization of nutrients with its additive effect.
3, fertilizer effect is fast.
The amino acids in amino acid fertilizers can be directly absorbed by various organs of the plant, and can be absorbed or permeated and absorbed passively under photosynthesis. Obvious effects can be observed within a short time after use, and at the same time, the early maturation of crops can be promoted and the growth cycle can be shortened.
4, improve the quality of crops.
Rich amino acid species can improve the quality of crops. If the protein content of grain increases by 3%, the quality of the cotton flower velvet is good, and the fiber is long; the palatability of the vegetables is good, the taste is pure and delicious, the crude fiber is reduced, the floral flowering period is long, the flower color is bright, the aroma is rich, the melon fruit is large, the pod color is a good candy The increase in the number of edible parts of the edible oysters is good, and the conversion efficiency is significant.
5, clean pollution-free, improve the ecological environment.
Amino acid fertilizers have no residue in the fertilizer applied to the ground, which can improve soil physicochemical properties, improve water retention and fertility and permeability, and play a role in curing, curing and improving soil.
6, enhanced metabolic function, increased resistance to stress.
Amino acids absorbed by crops can enhance their physiological and biochemical functions. The stems of the crops are thick, the leaves thicken, and the leaf area expands. The formation and accumulation of dry matter accelerates the early maturation of the crops and also enhances the cold-resistance, drought-resistance, dry-heat-resistance, and resistance to lodging and lodging of disease and insect pests as a result of their own vitality, thereby achieving stable and high yields.
7. Roots developed, strong absorption
Amino acids have a special role in promoting the development of roots in crops. Many agricultural scientists call amino acids “root fertilizers” and their effects on the root system mainly manifest in stimulating the division and growth of meristem cells at the root end, making the seedlings root quickly. The secondary roots increase, the root volume increases, and the roots elongate, eventually leading to a greatly enhanced ability of the crop to absorb water and nutrients.
8. Effect on the growth of trophozoites on the ground
On the basis of adequate supply of nutrients, the stimulation of amino acids can make the vegetative growth of the plant aboveground vigorously, manifested in plant height, stem diameter, number of leaves, dry matter accumulation and so on.
9. Effect on yield and compositional factors
The yield and composition of amino acids for different crops are different. For food crops, there are many crops, many grains, and a thousand grain weights, which have a good effect on the tillering and reduction of empty crops.
Effects of Amino Acids on Physiological Metabolism and Enzymatic Activities of Crops
After the amino acid enters the plant, it stimulates the plant, mainly in terms of increased respiratory intensity, increased photosynthesis, and increased activity of various enzymes, so that the fruit is colored and matured in advance, and high yield and output value are achieved.
According to Southwestern Agricultural University's test, after applying amino acids to watermelon, the sugar content increased by 13-31.3%, and the content of vitamin C increased by 32-4.6%.
