Special slow-release organic fertilizer for grapes and preparation method of fertilizer

Abstract

The invention provides a special slow-release organic fertilizer for grapes and a preparation method of the fertilizer. The special slow-release organic fertilizer for the grapes consists of lignin, diatomite, attapulgite, humic acid, calcium bentonite, castor bean meal, a nitrogenous fertilizer, a calcium magnesium phosphate fertilizer, a potash fertilizer, microelements and water. The microelements consist of agricultural rare earth, borax, copper sulfate, manganese sulfate and zinc sulfate heptahydrate. The preparation method comprises steps of dissolving, stirring and mixing components and performing granulation. The special slow-release organic fertilizer for the grapes is reasonable in component, the utilization rate of the fertilizer and the grape yield are increased greatly through the synergy of all the components, meanwhile, the problems of eutrophy and nutrient deficiency symptoms of crops are solved effectively, the taste of the grapes is greatly improved, the problem of water pollution caused by fertilizer loss is solved effectively, the soil is improved, resources are saved, and the cost is reduced; and the preparation method is simple and meets the requirement of 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 grapes and a preparation method thereof. Background technique [0002] During the planting of grapes, 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 grapes, resulting in a lack of nutrients. Artificial Auxiliary addition. However, grapes require as many as 17 types of nutrients, including carbon, hydrogen, oxygen; nitrogen, phosphorus, potassium; calcium, magnesium, sulfur, etc., and different varieties of grapes have different requirements for nutrients, so compound fertilizers, Compound fertilizer, soil test formula fertilizer, in order to achieve balanced nutrient absorption of crops. Howev...

AI Technical Summary

Problems solved by technology

However, long-term production practice has found that the absorption rate of nutrients by various grapes 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 deficiency in the grape growing process and the water pollution caused by the loss of instant fertilizer
