Special slow-release organic fertilizer for pear trees and preparation method thereof

Abstract

The invention provides a special slow-release organic fertilizer for pear trees and a preparation method thereof. The special slow-release organic fertilizer comprises lignin, diatomite, attapulgite, humic acid, calcium bentonite, a nitrogen fertilizer, a phosphatic fertilizer, a potassium fertilizer, microelements and water, wherein the microelements comprise agricultural rare earth, borax, ferrous sulfate, copper sulfate, manganese sulfate and zinc sulphate heptahydrate. The preparation method comprises the following steps: dissolving, stirring, mixing and granulating the components. A formula of the special slow-release organic fertilizer is reasonable, the utilization rate of the organic fertilizer and the yield of the pear trees are greatly increased through the synergistic effect of the components, the problem of over-nutrition or nutrient deficiency symptom of crops is effectively solved, the mouth feel of pears is greatly improved, the problem of water body pollution caused by fertilizer loss is effectively prevented, the soil is improved, the resources are saved, and the cost is reduced; the preparation method is simple and meets the needs 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 pear trees and a preparation method thereof. Background technique [0002] Pear trees need to use chemical fertilizers during the planting process. 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 pear trees, resulting in nutrient deficiency. Add human assistance. However, pear trees require as many as 17 kinds of nutrients, including carbon, hydrogen, oxygen; Fertilizer, compound fertilizer, soil test formula fertilizer, in order to achieve balanced nutrient absorption of crops. However, long-term production practice has found that the absorption rate of nutrients by various pear trees is different and non-linear, so controlled-releas...

Problems solved by technology

However, long-term production practice has found that the absorption rate of nutrients by various pear trees is different and non-linear, so controlled-release fertilizers were invented, mainly sulfur-coated and wax-coated technologies, bu
