Description
Technical field
The invention belongs to Crop fertilizer field, in particular to a kind of polymerization carbosphere Fertilizer slow-release synergistic agent and its preparation
Method.
Background technique
China is agricultural development big country, and cultivated area is few, low grain yield is greatest problem that China's agricultural development faces,
The important means for improving grain yield at present are application chemical fertilizer.China is maximum chemical fertilizer production and the state used in the world
Family, year applying quantity of chemical fertilizer account for the 35% of world's total amount, but the utilization rate of chemical fertilizer is far below developed country less than 30%.Due to chemical fertilizer
Utilization rate it is low, in order to pursue higher yield of crops, peasant largely applies chemical fertilizer, not only increases financial burden, and to soil
Earth pollutes, and soil is made phenomena such as saline and alkaline, barren, hardened occur, destroys ecological environment of soil, influences the growth of crops,
The loss of chemical fertilizer can cause organic contamination to water body simultaneously, the living environment structure of sustainable development and the mankind to China's agricultural
At seriously threatening.Therefore, how to improve fertilizer efficiency and reduce fertilizer loss, improve soil environment, it has also become China's agricultural
The significant problem of sustainable development.
