Production method of controlled release chemical fertilizer based on hylocereus undulatus leaves

Abstract

The invention provides a production method of a controlled release chemical fertilizer based on hylocereus undulatus leaves, belongs to a production process of a controlled release chemical fertilizer, and particularly relates to a production method of a controlled release adjustable chemical fertilizer. The production method comprises the step of adding hylocereus undulatus leaf extract on the basis of a traditional process after urea is completely melted. By virtue of the technological means, only the hylocereus undulatus leaf extract needs to be added on the basis of a traditional controlled release chemical fertilizer, so that the controlled release effect of the traditional controlled release chemical fertilizer can be adjusted; the chemical fertilizer prepared by the method not only has an ideal controlled release effect but also has a simple process and is low in production cost; meanwhile, secondary pollution to soil is not caused; and more importantly, the controlled release effect can be adjusted so that the chemical fertilizer can meet wide market requirements.

Description

technical field [0001] The invention discloses a method for manufacturing slow-controlled release chemical fertilizers based on keel flowers and leaves, which belongs to the manufacturing process of slow-controlled release chemical fertilizers, and in particular relates to a manufacturing process of slow-controlled release adjustable fertilizers. Background technique [0002] At present, there are mainly four types of slow-release fertilizers in the international fertilizer market: stable nitrogen fertilizers containing transformation inhibitors, organically synthesized slow-release nitrogen fertilizers, polymer-coated slow-release fertilizers and coated slow-control fertilizers. Release fertilizer. [0003] First, stable nitrogen fertilizer containing transformation inhibitors [0004] Hydrogen and ammonium dihydrogen are usually used to inhibit urease and nitrification agents. Its main function is to inhibit nitrogen loss during urea conversion and nitrification, reduce g...

AI Technical Summary

Problems solved by technology

However, the slow-release effect of this fertilizer will be affected by factors such as moisture and microorganisms, and the slow-control effect is not ideal.

For this reason, the invention patent with the application number 201110244080.1 "A Manufacturing Method of Spraying Sulfur Resin Type Slow and Controlled Release Fertilizer", the chemical fertilizer manufactured through this invention belongs to the inorganic package slow and controlled release fertilizer, which not only has a slow and controlled release effect, but also The process is simple, the production cost is low, and there will be no secondary pollution to the soil. Most importantly, it solves the problem of unsatisfactory slow and controlled release effects of traditional inorganic packaged slow and controlled release fertilizers

[0011] To sum up, inorganic packaged slow and controlled release fertilizers are the future development direction of slow and controlled release fertilizers. Unfortunately, at this stage, the slow and controlled release effect of this type of fertilizer is constant and cannot be adjusted according to needs.
