Sustained-release organic fertilizer special for peanuts and preparation method thereof

Abstract

The invention provides a sustained-release organic fertilizer special for peanuts and a preparation method thereof. The sustained-release organic fertilizer special for the peanuts consists of lignin, diatomite, attapulgite, humic acid, calcium-based silicate mineral, a nitrogen fertilizer, a phosphate fertilizer, a potassic fertilizer, trace elements and water, wherein the trace elements consist of agricultural rare-earth, borax, ammonium molybdate, manganese sulfate and zinc sulphate heptahydrate; the sustained-release organic fertilizer special for the peanuts is prepared according to the preparation method of dissolving the components, stirring, mixing and granulating. The sustained-release organic fertilizer special for the peanuts has a reasonable formula; the utilization rate of the organic fertilizer as well as the yield and the oil yield of the peanuts is greatly improved by the synergistic effect of the components; meanwhile, the problems of eutrophication or nutrient deficiency symptoms of crops are solved; the taste of the peanuts is greatly improved; meanwhile, the problem of water body pollution caused by fertilizer loss is prevented effectively; the soil is improved; resources are saved; the cost is reduced; the preparation method is simple and meets the requirements on large-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 peanuts and a preparation method thereof. Background technique [0002] The use of chemical fertilizers is required in the planting process of peanuts. 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 the rapid growth of peanuts, resulting in a lack of nutrients. Artificial Auxiliary addition. However, peanuts require as many as 17 kinds of nutrients, including carbon, hydrogen, oxygen; nitrogen, phosphorus, potassium; calcium, magnesium, sulfur, etc., and different varieties of peanuts have different requirements for nutrients, so compound fertilizers, Compound fertilizer, soil test formula fertilizer, in order to achieve balanced nutrient absorption ...

AI Technical Summary

Problems solved by technology

However, long-term production practice has found that the absorption speed of various peanuts 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 peanut growth process and the water pollution caused by the loss of instant fertilizers
