AI Technical Summary

Problems solved by technology

The utilization rate of fertilizers is very low. The main reasons are: unsuitable amount of fertilization (too much or insufficient), incorrect application period, land conditions, methods or fertilizers used, and the leaching, erosion, volatilization, and reaction of fertilizers in the soil. Losses caused by nitrification, fixation, etc.
The low utilization rate of fertilizers will cause waste of fertilizers, energy waste, soil, groundwater, air pollution, and crop quality reduction.
At the same time, it also increases the economic burden on farmers
[0003] Existing fertilizer synergists are cumbersome to make, inconvenient to use, with various varieties and uneven effects

Abstract

The invention discloses a fertilizer slow-release synergistic agent and a preparation method thereof. The fertilizer slow-release synergistic agent comprises the following raw materials in percentage by mass: 0.1-20 % of polyaspartic acid and slat thereof, 0.1-10 % of urease inhibitor, 0.1-30 % of nitrification inhibitor, 0.03-5 % of plant growth regulating agent, 10-35 % of soil regulating agent and 10-80 % of carrier. The fertilizer slow-release synergistic agent disclosed by the invention is mainly used for the slow-release synergism of a compound mixing fertilizer, is increased in the utilization rate of the fertilizer, and is capable of effectively improving the soil, and the soil moisture can be preserved; and when the fertilizer slow-release synergistic agent is used, the fertilizer slow-release synergistic agent can be added into a material feeding system or an enveloping drum together with the fertilizer raw materials and mixed with the fertilizer raw materials, the effect of slow-release synergism can be realized, and the dosage of the fertilizer slow-release synergistic agent is 4-8 kg per ton fertilizer.

Description

technical field [0001] The invention relates to a fertilizer synergist, in particular to a fertilizer slow-release synergist and a preparation method thereof. Background technique [0002] my country is a big agricultural country, and it is also a big country in the production and use of chemical fertilizers. my country's chemical fertilizer production accounts for about 20% of the world's total output, and its application rate accounts for about 30%, ranking first in the world. However, according to my country's fertilizer-related measurements, the utilization rate of nitrogen in chemical fertilizers is 30%-70%, and that of phosphate fertilizers is 10%. %-25%, potash fertilizer is 40%-70%. The utilization rate of fertilizers is very low. The main reasons are: unsuitable amount of fertilization (too much or insufficient), incorrect application period, land conditions, methods or fertilizers used, and the leaching, erosion, volatilization, and reaction of fertilizers in t...
