Eight Characteristics of Polyglutamic Acid(PGA)
1.It has super hydrophilicity and water retention: after spraying on various plants for Experimentation, the maximum natural water absorption can reach 1108.4 times. The water absorption factor in the soil is 30-80 times. It has strong drought resistance and water saving.
2.Contains very high nutrients to provide adequate nutrients for plant cell division and plant growth points. Various plants seeds soaked or mixed with 50-200 times solution according to different crops, can form a film on the surface of seeds and roots, which not only has the function of protecting root hair, but also makes soil moisture, nutrients, etc.
An optimal nutrient delivery platform is formed between the seed root hair and the active ingredient is fully delivered to the plant。 It can effectively promote the germination of seeds and the development of roots, so that it grows longer roots and more roots hairs, increases the surface area of roots, improves the ability of crops to absorb nutrients, and enhances art growing such as the drought resistance, cold resistance and disease resistance of crops。
3.It has good nutrition and adjustment for plants. Foliar spraying or rooting at various stages of plant growth and development can promote both vegetative growth and reproductive growth. After being absorbed by the leaves, stems and roots of the plant, then transmitted to the active part, the leaf senescence can be delayed effectively, the protection time is long, the synthesis of strong chlorophyll as well as the photosynthesis are increased, and the leaf color is deepened to become green and thick.
4。It can effectively enhance the ability of disease resistance and environmental resistance。 The diseases in the soil are mainly caused by the long-term usage of chemical fertilizers; Due to the rich oxidation of the soil, various pathogenic microorganisms are produced, which the root cause of the illness of the plants。
Polyglutamic acid(PGA) can activate various fertilizer salts in the soil, inhibit the growth of various pathogens, reduce the production of pathogenic microorganisms, and achieve a good disease resistance.
5.Enrichment of nutrients and increase fertilizer utilization rate: The adsorption and exchange capacity of Polyglutamic acid(PGA) is 100 times of natural soil, which can reduce nutrient loss and volatilization effectively. While enriching nitrogen, phosphorus and potassium, it also enriches the micro-nutrients such as calcium, magnesium, molybdenum and zinc, which meets the various needs of crops.
By using PGA, the nitrogen fertilizer utilization rate can be increased by at least 50%-60%, the phosphate fertilizer can be increased by more than 50%, and the potassium fertilizer can be increased by 15%-20% minimum. The fertilizer is more than 30% per acre, and the symptoms of deficiency are not easy to occur.
Polyglutamic acid(PGA) has a long-lasting mitigation function and can store nutrients that plants do not use temporarily. With the growth and development of crops, they are slowly released according to the needs of different stages, so as to meet the nutrient requirement of the crop in the middle and late stages, this avoids premature aging and de-fertilization, reduces the topdressing frequency and quantity. Applying PGA as the base fertilizer of the food crops can fulfill the fertility needs for the entire reproductive period.
6。The effect of increasing production is significant。 After three years of experimental demonstrations, the use of Polyglutamic acid(PGA) can increase the average yield of food crops, eggplant crops, oil crops and leafy vegetables by more than 25%, 30%, 15% and 40% respectively。 Whilst, it can also improve the quality of agricultural products, and is the best choice for developing pollution-free agricultural products, green food and organic foods。
7.It has been proved by experiments that Polyglutamic acid(PGA) has detocification effect on most herbicides.
Combined with herbicides, it can effectively prevent crop poisoning and improve the safe use of herbicides without reducing the effect of herbicides.
Combined with fungicides, it can increase efficiency by more than 35%。
Combined with insecticides, it can increase the insect resistance of plants with a synergy by 30%. Meanwhile, it also has a repellent effect on soft worms, achieving the purpose of killing insects, treating diseases and increasing production.
8。Natural, organic and environmental protection: Polyglutamic acid(PGA) nutrient solution is a nutrient without toxic side effects。 Its degradant in the soil not only has no residual toxicity, but also has the excellent embedding effect on toxic heavy metals in the soil such as lead, copper, chromium, cadmium, aluminum, arsenic and antimony, so as to avoid the adsorption of toxic heavy metals to plants, and pollute the agricultural products。
