High-activity nitrification inhibition type multifunction fertilizer synergist and preparation method thereof

Abstract

The invention relates to a high-activity nitrification inhibition type multifunction fertilizer synergist and is applicable to the field of agriculture and forestry. The high-activity nitrification inhibition type multifunction fertilizer synergist is composed of following raw materials of, by weight, 3-35% of vitamin C, 3-35% of N-acyl sodium glutamate, 3-35% of 3,4-dimethylpyrazole phosphate (DMPP), 3-35% of farm-oriented rare earth, 5-35% of fulvic acid, 0.5-2.5% of compound sodium nitrophenolate, 15-45% of vermiculite and 15-45% of medical stones. The raw materials are smashed, screened by a 30-100 mesh screen, then stirred and mixed according to a certain ratio to obtain the fertilizer synergist. The fertilizer synergist is applicable to slow-acting nitrogen fertilizers or composite nitrogen fertilizers which use ammonium nitrogen fertilizers or urea as raw materials and is capable of being matched with the ammonium nitrogen fertilizers or the urea to be simultaneously applied to various types of soil, the fertilizer efficiency period of nitrogen fertilizers with the added multifunction fertilizer synergist can be prolonged to 90-110 days, abilities of drought resistance and disease resistance can be obviously improved, soil microorganism activities and crop root system activities can be stimulated, effectiveness and utilization efficiencies of soil fertilizers can be improved, and residual effects on crops are obvious.

Description

technical field [0001] The invention relates to an agricultural fertilizer synergist, in particular to a highly active nitrification inhibiting multifunctional fertilizer synergist. Background technique [0002] At present, my country's fertilizer utilization rate is still at a relatively low level compared with developed countries, and the high-efficiency long-acting multifunctional compound fertilizer (compound fertilizer) in the domestic market is accounted for by multinational companies. The market development space of my country's domestic high-efficiency long-acting compound fertilizer. The length of the fertilizer effect mainly depends on the length of the nitrogen fertilizer effect. Nitrogen long-term nitrification inhibition technology, the inhibition effect is more than three times that of common domestic imported fertilizers. The main function is to control the activity of urease and nitrosifying bacteria that decompose nitrogen in the soil biochemical environmen...

Problems solved by technology

However, the price of conventional compound nitrogen fertilizers is also relatively expensive, and the fertilizer effect is not significant. There is still a big gap between the advantages of fertilizer efficiency and the products of multinational companies such as Entec series compound fertilizers and Batian blue compound fertilizers of the German Potash Group. Therefore, domestic The international competitiveness of compound fertilizer needs to be improved
