D-phenylalanine USES

1, improve fertilizer utilization

The experiment of aspartic acid on peanut showed that the nitrogen, phosphorus and potassium nutrients in soil maintained high availability in each period after application of aspartic acid. The utilization rate of nitrogen fertilizer increased by 15.3%, the utilization rate of phosphorus fertilizer increased by 8.3%, and the utilization rate of potassium fertilizer increased by 10.7%. It can save about 20% fertilizer per acre, and it is not easy to have deficiency symptoms.

2. Increase crop yield

Aspartate has the dual role of promoting cell division and cell elongation, can increase the content of leaf chlorophyll, enhance photosynthesis, and increase the accumulation of photocontract products, so it has obvious effects on promoting plant nutritional growth, can promote plant growth and development, and increase crop yield. Studies have shown that proper addition of aspartic acid can increase the yield of wheat, rice, corn and other crops, and increase the yield per unit area and total yield.

3. Improve crop quality

Aspartate can improve the quality of crops. Adding an appropriate amount of aspartate can not only improve the quality of fruits and vegetables, but also improve the nutritional value of food crops, such as increasing the content of proteins, amino acids and other components. By promoting the absorption of medium and trace elements, aspartic acid can achieve the coordinated supply of crop nutrients and improve crop quality. Malnutrition and malformation caused by the use of hormones are avoided. Fruit, bald tip, cracked fruit and poor coloring.

4, seedling stage to promote root growth, enhance stress resistance

It can promote the growth of seedling roots of fields, flowers, medicinal materials, soybean, tobacco, vegetable and fruit trees, etc. Compared with the control, the root fresh weight increased by 20% ~ 50%, and the dry weight increased by 15% ~ 107%. Aspartic acid is not a hormone, but it can effectively promote the development of crop roots, make it grow longer roots and more root hair, increase the surface area of the roots, improve the ability of crops to absorb nutrients, and enhance the ability of crops to resist lodging, drought resistance, resistance to disease. Aspartic acid can improve the stress resistance of crops and make them more adaptable to complex environments. By adding aspartic acid, the plant’s immunity and antioxidant capacity are increased, making the crop more resistant to the environment.

5, green environmental protection, improve soil

First of all, aspartate itself is non-toxic, pollution-free, degradable, hormone-free, heavy metal-free, and environment-friendly products without any side effects, which can improve the soil environment.

Secondly, aspartic acid can reduce the adverse impact of excessive fertilization on the environment, and can also activate the nutrient elements in the soil in a fixed state, which not only improves the utilization rate of fertilizer, but also improves the soil quality.

6. Reduce drug damage

The use of polyaspartate products together with copper preparations and deisen pesticide products can reduce the drug damage caused by excessive use of these two products, so as to achieve the effect of crop protection.
