Organic peanut planting controlled-release functional fertilizer and preparation method thereof

Abstract

Animal hair in life is a waste energy, the protein structure of the animal hair is stable and difficult to decompose under the natural condition, poultry feather and pig hair are used as raw materials to be mixed with alkaline substance slaked lime and sodium bicarbonate, the mixture is firstly soaked and then boiled, after the structure of the poultry feather and pig hair is destructed, the poultry feather and pig hair are ground and fermented to be used for preparing organic matters of the fertilizer, so that waste is utilized, the environment pollution is avoided, the resource is saved, the inner layer contains NPK (Nitrogen, Phosphorus and Potassium) element and trace minerals which are necessary for the high yield of crops, the NPK element and trace minerals are wrapped by a coating agent prepared by utilizing the resin so as to be used as a core of the organic fermented material, a film material is slowly decomposed, an effect for controlling the release of internal nutrients can be achieved, the waste caused by frequent application of fertilizer can be avoided, the cost is reduced, and the economic benefit is increased.

Description

technical field [0001] The invention relates to an organic slow-release functional fertilizer for peanut planting and a preparation method thereof, belonging to the technical field of organic slow-release fertilizers in fertilizers. Background technique [0002] Chemical fertilizer is the largest material input in agricultural production. According to the statistics of the Food and Agriculture Organization of the United Nations, chemical fertilizers account for 40-60% of the increase in yield. However, the production time shows that due to the nature of the fertilizer itself and the soil Due to the impact of environmental conditions and agricultural measures, the utilization rate of chemical fertilizers is very low. The waste of nutrient resources caused by the low utilization rate of fertilizer nutrients in China is astonishing. According to statistics, the annual production and application of nitrogen fertilizer in China is about 20 million tons, and the seasonal utilizati...
