Preparation Method.
Background technology
China is the first in the world populous nation, Ye Shi large agricultural country, and dividing that grain-production occupies in agricultural production is important
Status, improve per unit area yield of grain major way be in agricultural production use chemical fertilizer.China's fertilizer production
It is all the first in the world with usage amount, but the Fertilizer application of China exists problems: (1) utilization rate of fertilizer is low, fertilizer loss
Cause environmental situation serious.Although China puts into every year substantial amounts of fertilizer application in agricultural production, but utilization rate of fertilizer with
Developed country compares and has a long way to go.Compare the utilization rate of fertilizer of developed country 55%, China's chemical fertilizer utilization ratio averagely less than 30%,
Proving according to the study, this season utilization rate nitrogenous fertilizer of China's fertilizer is 30%～35%, and phosphate fertilizer is 10%～25%, potash fertilizer be 35%～
50%.The lowest owing to applying too much chemical fertilizer or utilization rate of fertilizer, the material such as soil water soluble nutrient is by rainwater and farmland irrigating
Water leaching, in subsoil water and river, causes subsoil water and the river pollution of some areas, and making subsoil water, river, lake is richness
Nutrient laden, causes that subsoil water is bad to be drunk, and the fish and shrimp in partial rivers, lake often occur the phenomenon of death.(2) singly execute or executing partially
Fertilizer brings the problems such as serious Soil Nutrients in Farmland destruction.All the time, the fertilizer production in the whole world is concentrated mainly on crop demand
