Abstract

The invention relates to a high-efficiency slow / controlled-release fertilizer which is composed of the following components in parts by weight: 3-8 parts of potassium chloride, 6-10 parts of calcium sulfate, 2.5-6 parts of growth regulator, 7-12 parts of carbamide, 1.5-4 parts of sodium glutamate, 0.6-1.8 parts of manganese sulfate, 2.2-4.6 parts of peanut pulp powder, 1-4 parts of lime powder, 1.5-3.2 parts of minor element, 0.3-0.7 part of copper sulfate, 1.1-2.5 parts of slow-release agent and 1-3 parts of coating agent. The fertilizer can provide sufficient nutrients according to plant growth needs, has long action time, and is capable of reducing the raw material waste, lowering the environmental pollution and enhancing the economic value.

Description

technical field [0001] The invention relates to a high-efficiency slow-release and controlled-release fertilizer. Background technique [0002] In a broad sense, slow and controlled release fertilizers refer to fertilizers whose nutrient release rate is slow and the release period is long, which can meet the needs of crop growth during the entire growth period of crops. But in a narrow sense, there are different definitions for slow-release fertilizers and controlled-release fertilizers. Slow-release fertilizers, also known as long-acting fertilizers, mainly refer to fertilizers that transform into effective nutrients for plants after being applied to the soil at a slower rate than ordinary fertilizers. Its release rate, mode and duration cannot be well controlled, and are greatly affected by fertilization methods and environmental conditions. The principle of controlled-release fertilizer release is that when the nutrients in the fertilizer change from solid to liquid, th...
