Technical field
The present invention relates to the technical field of fertilizer, more particularly to a kind of plantation of early rice high sustained release compoiste fertilizer and its system
Preparation Method.
Background technology
China is Rice Cropping big country, and current Rice Cropping is mostly straight fertilizer with fertilizer, due to straight fertilizer cost
It is low, current China's Rice Production with fertilizer still using the straight fertilizer such as carbon ammonium, urea, calcium superphosphate or calcium magnesium phosphate, potassium chloride as
Main, for peasant, although China widelys popularize Formula fertilization by soil testing, how scientific and reasonable fertilising is still difficult.When
Before, compound compound fertilizer development trend is very fast, but compound fertilizer formula is using chaotic, irrational to be formulated applied to crops more
Crop production reduction or fertilizer loss aggravation are easily caused, and with economic development, peasant's fertilising pursuit recruitment is few and operation is simple
Single single fertilization, and fertilizer release rule and crop growth demand in soil is complete on the contrary, so causing seedling stage to need
Soil nutrient content reaches highest when fertilizer is few, and soil nutrient is but preferably minimized when needing fertile more into growth period, therefore current
Fertilizer and corresponding fertilizer practice so that China's utilization rate of fertilizer is chronically at reduced levels, have had a strong impact on the kind grain of peasant
