Abstract
The invention relates to a quick effective seedling nourishing controlled release compound fertilizer and production method thereof, wherein the fertilizer comprises at least amendment, solubilizing agent and active agent fertilizer control release architecture, and the production method comprises the steps of, mixing the raw materials proportionally and bruising, disintegrating the bonding agent to 80-100 mesh, proportioning while measuring, granulating and charging amendment, solubilizing agent and active agent, then drying the glutinous or column shaped materials.
Description
Technical field
The present invention relates to a kind of quick-acting strong seedling controlled-release compound fertilizer and production method thereof, particularly relate to a kind of quick-acting strong seedling controlled-release compound fertilizer and production method thereof that adapts to farm crop growth of seedling needs and prepare.
Background technology
Existing release fertilizer technology mainly adopts following several method to impel the seedling of crop to turn green:
(1) is affixed by simple substance nitrogenous fertilizer;
(2) not add any coating agent behind N, P, the K granulation of fertilizer;
(3) wrap up activator and sustained release dosage simultaneously at particle surface.
Above several method all can make crop seedling turn green, but (1) kind method nitrogenous fertilizer easily runs off, and utilization rate of fertilizer is low, and peasant's labour intensity is strengthened; (2) kind method seedling turns green slowly; (3) kind method activator can make the strength degradation of coating agent, need between the two to require strict coupling simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of quick-acting strong seedling controlled-release compound fertilizer and production method thereof, it can impel crop to turn green fast, and need not to impose other fertilizer, improves utilization rate of fertilizer.
The objective of the invention is to realize in the following way: quick-acting strong seedling controlled-release compound fertilizers, at least comprise nitrogenous source, the phosphorus source, the nutrient system in potassium source, according to external environment (as soil, light, accumulation temperature etc.) requirement, to comprising amendment at least, the fertilizer sustained release system of solubilizing agent and promoting agent, physiology and biological need situation by crop are carried out corresponding allotment, promote the dissolving of the required nutrient of crop, reduce the surface tension of solution (moisture) in the soil, promote nutrient matter stream migration in soil,, played seedling and turned green soon nutrient absorbing in order to crop root, strong seedling, promote the effect of root system development.
With urea, phosphorus ammonium, Repone K is main raw material, it is characterized in that, comprises the fertilizer sustained release system of binding agent, amendment, solubilizing agent, promoting agent, little fertilizer additive at least,
