Polyaspartic acid is a water-soluble high molecular amino acid polymer, which was first discovered by Dong Na Company. Polyaspartic acid has been widely used in North America because it can significantly promote the absorption of nutrients by plants, increase crop yield and save fertilizer consumption. 1996, American Dong Na Company won this year's "American President's Green Chemistry Challenge Award". Subsequently, German, Japanese and China also started R&D projects in the late 1990s, and all of them were successful. China's R&D work is undertaken by Beijing Yin Tian Aishihua Technology Co., Ltd., and the green and rich polyaspartic acid successfully developed and industrially produced by it is non-toxic, completely degradable, pollution-free and free of heavy metals, and has no pollution or adverse effects on people and animals and the natural environment. In April of 20001,it passed the appraisal of scientific and technological achievements of the Ministry of Agriculture (No.200 1-028), and was included in the National Torch Plan (2003EB060095) in 2003, which was the key promotion and industrialization project of environmental protection and pollution-free ecological agriculture of the Ministry of Agriculture and the scientific and technological development project of improving tobacco quality of the State Tobacco Monopoly Bureau. In the same year, it was listed in the high-tech achievement transformation project of Beijing Science and Technology Commission (03 1500098B) and Beijing high-tech new products (new product certificateNo. 2003H0000-0438); Hainan Provincial Department of Agriculture recommended pollution-free fertilizer products. 2003 13); Its synthesis technology passed the appraisal of China Petrochemical Co., Ltd. in 2004 (Sinopec J.Z. 2004No. 156), and in the same year, it applied for the national invention patent of "Synergistic Urea (Polypeptide Urea) and its preparation method and application" (patent applicationNo.: 01KLOC-0/0369.8). Can be used alone (such as foliar spraying, root application, seed soaking, seed coating agent, etc.). ), can also be used as fertilizer synergist to produce green abundant source (polyaspartic acid) synergistic urea (polypeptide urea) and green abundant source (polyaspartic acid) synergistic compound fertilizer. As a fertilizer synergist, it is the raw material of polypeptide urea, polypeptide compound fertilizer and controlled release fertilizer, which can promote the absorption of nutrients by crops such as grain, vegetables, fruits and flowers, and at the same time, it can improve the efficacy when used in combination with pesticides. The research and application results at home and abroad show that polyaspartic acid is an effective plant nutrient absorption promoter, which is suitable for many plants and soils. Its main features are as follows:
Features 1. Reduce the loss of chemical fertilizer, activate nutrient elements, and improve the utilization rate of chemical fertilizer, thus reducing the dosage of chemical fertilizer by 30% and increasing the yield by 10%-30%.
Second, it can promote the absorption of trace elements such as iron, zinc and manganese by crops, and the content of trace elements in crops treated with polyaspartic acid is 3-4 times higher than that in control crops.
Feature 3: Promote the early maturity of crops by 7- 10 days and extend the harvest period by 10- 15 days.
Feature 4: Promote root growth and enhance stress resistance. Widely used in industrial circulating water, oilfield water, boiler water, reverse osmosis water, seawater desalination and other water treatment fields, it has excellent performance in systems with high hardness, high alkalinity, high PH value and high concentration multiple, and its scale inhibition effect is better than that of ordinary phosphorus-containing scale inhibitors. Using this product instead of phosphine-containing water treatment agent can avoid eutrophication and secondary pollution of water body.
