Problems solved by technology

However, long-term production practice has found that the absorption speed of various soybeans is different and non-linear, so controlled-release fertilizers were invented, mainly sulfur-coated and wax-coated technologies, but the utilization rate of instant fertilizers still cannot be solved. , and thus cannot solve the problem of eutrophication or deficiencies in the soybean growth process and the water pollution caused by the loss of instant fertilizer

Abstract

The invention provides a special soybean controlled-release organic fertilizer and a preparation method thereof. The special soybean controlled-release organic fertilizer consists of xylogen, diatomite, attapulgite, humic acid, calcium-based silicate, castor meal, a nitrogenous fertilizer, a phosphatic fertilizer, a potassic fertilizer, microelements and water, wherein the microelements comprise borax, magnesium sulfate, ammonium molybdate, manganese sulfate and zinc sulfate heptahydrate. According to the preparation method, the components are formed by mixing and pelletizing after dissolving and stirring. The special soybean controlled-release organic fertilizer has a reasonable formula; the use rate of the organic fertilizer and the yield and the oil yield of soybeans can be greatly improved through the synergistic effect of the components; meanwhile, the problems of the eutrophy or nutrient deficiency symptom of crops can be effectively solved, so that the commodity of the soybeans can be greatly improved; the pollution problem of a water body caused by fertilizer runaway can be effectively prevented; soil can be improved; the resources can be saved; the cost is reduced; the preparation method is simple and is suitable for demands on scale industrial production.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a special slow-release organic fertilizer for soybeans and a preparation method thereof. Background technique [0002] During the planting of soybeans, chemical fertilizers need to be applied. However, the use of chemical fertilizers artificially changes the evolution process of the soil, so that in the existing agricultural production process, the natural weathered minerals cannot meet the needs of rapid growth of soybeans, resulting in a lack of nutrients. Artificial Auxiliary addition. However, soybeans require as many as 17 types of nutrients, including carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium; calcium, magnesium, sulfur, etc., and different varieties of soybeans have different requirements for nutrients, so compound fertilizers, Compound fertilizer, soil test formula fertilizer, in order to achieve balanced nutrient absorption of cro...
