Special long-acting slow-release compound fertilizer for peanut yield increase

Abstract

The invention relates to the field of compound fertilizers for crops, and particularly relates to a special long-acting slow-release compound fertilizer for peanut yield increase. The special long-acting slow-release compound fertilizer is prepared from the following raw materials in parts by weight: 12-15 parts of ammonium persulfate, 15-18 parts of ammonium nitrate, 25-28 parts of ammonium phosphate, 4-6 parts of lemon residues, 12-15 parts of soybean meal, 8-10 parts of rape seed cakes, 4-5 parts of alfalfa hay, 24-28 parts of potassium chloride, 2-5 parts of zinc sulfate, 5-8 parts of sodium borate, 2-3 parts of starch, 2-4 parts of ferrous sulfate, 6-8 parts of silicone acrylic emulsions, 1-2 parts of silane coupling agents, 2-4 parts of sodium bicarbonate, 1-2 parts of lauryl sodium sulfate, 12-15 parts of waste beer yeasts, 10-12 parts of grape pomace and 3-5 parts of auxiliary agents. The special long-acting slow-release compound fertilizer disclosed by the invention is prepared into powder with activated adsorption property by utilizing the lemon residues and the grape pomace, plays a role of fertilizer immobilization by preparing the lemon residues and the grape pomace into powder with activated adsorption property and mixing the powder with the raw materials, namely a fermentation solution of multiple organic substances, a medium trace element, an auxiliary agent and the like, realizes the fertilizer controlled-release capacity by utilizing a slow-release coating agent, has the advantages of more lasting fertilizer effect, vigorousness in crop growth and obviousness in yield increase effect and can not break the ecological balance of soil by being applied for a long time.

Description

technical field [0001] The invention relates to the field of special compound fertilizers for crops, in particular to a long-acting slow-release compound fertilizer special for increasing peanut production. Background technique [0002] Compound fertilizer plays an extremely important and indispensable role in modern agriculture. Compared with traditional organic fertilizers, it has the advantages of many types of nutrients, high content, high nutrient utilization rate, and convenient packaging, storage, and application. It is the future chemical fertilizer. direction of development. However, most of the existing compound fertilizers have a relatively fixed nutrient ratio, which cannot meet the growth needs of different soil environments and different crop varieties at each growth stage, and eventually lead to the ineffective loss of fertilizer efficiency, and cannot achieve a satisfactory effect of increasing production and income. Therefore, it is very It is necessary to ...
