Abstract

The present invention discloses a long-acting slow-controlled biological fertilizer which comprises the ingredients in parts by mass: 6-8 parts of a water absorbent, 30-40 parts of pig manure, 15-20 parts of ammonium sulfate, 15-20 parts of ammonium phosphate, 15-20 parts of potassium sulfate, 15-20 parts of magnesium sulfate, 20-30 parts of calcium superphosphate, 20-25 parts of decomposed coal, 12-18 parts of sweet potato powder, 40-60 parts of urea, 5-10 parts of kaolin and 2-4 parts of microelement fertilizers.The biological fertilizer is low in cost, has a long-acting slow-controlled characteristic and is liable to prepare.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a long-acting slow-control biological fertilizer. Background technique [0002] Long-acting slow-control fertilizers refer to fertilizers whose nutrient release rate is slow and the release period is long, which can meet the growth needs of crops throughout the growth period of crops. But in a narrow sense, there are different definitions for slow-release fertilizers and controlled-release fertilizers. Slow-release fertilizers (SRFs), also known as long-acting fertilizers, mainly refer to fertilizers that are converted into effective plant nutrients at a slower rate than ordinary fertilizers after being applied to the soil. Its release rate, mode and duration cannot be well controlled, and are greatly affected by fertilization methods and environmental conditions. The advanced form of slow-release fertilizer is controlled-release fertilizer (CAFS), which refers to pre-se...
