Description
Technical field
The present invention relates to agricultural fertilizer preparation fields, and in particular to a kind of preparation method of bagasse base Slow release organic fertilizer.
Background technology
China is large agricultural country, but is had a large population and a few land, and cultivated area is only the soil gross area 10% or so, and per capita cultivated land is average
Only 0.08 hectare.Chemical fertilizer plays obvious action as a kind of important agricultural material product to improving crop yield, is Modern Agriculture
The indispensable production factors of industry.According to national chemical fertilizer net statistics, external nitrogenous fertilizer in this season utilization rate 60%-70%, and I
State's nitrogenous fertilizer this season utilization rate is 30%-35%, phosphate fertilizer 10%-25%, potash fertilizer 35%-50%, but wherein with the volatilization of nitrogen
Loss is the most serious.The utilization rate of nitrogenous fertilizer is low, hinders China's Agriculture Production.
For people for a long time largely using inorganic fertilizer, in addition occupation mode is improper, fertilizer interest rate use is not high, causes fertilizer a large amount of
Loss, soil and water body are polluted, crops resistance decline, it is serious threatened agricultural sustainable development.Have
Machine fertilizer can not only provide full nutrition for crops, and fertilizer efficiency is long, can increase and update the soil organism, promote microorganism numerous
It grows, improves the physicochemical property and bioactivity of soil, be the Main Nutrients of pollution-free food production.Meanwhile by adding in fertilizer
Add long-acting sustained-release agent, inhibit the activity of certain enzymes in soil to slow down the decomposition and inversion of nitrogen be also improve utilization rate of fertilizer one
Effective way.
Representative of the coated slow release fertilizer as fertilizer product of new generation, by adding long-acting sustained-release agent in fertilizer, inhibits
In soil the activity of certain enzymes come slow down the decomposition and inversion of nitrogen be improve utilization rate of fertilizer an effective way.Many people are slow
