Preparation method of crop and fruit tree fertilizer and application

Abstract

The invention provides a preparation method of a crop and fruit tree fertilizer. The preparation method comprises the steps of grinding raw materials into meat paste or powder by utilizing a meat grinder or a pulverizer, soaking in water, removing moisture, then adding a bacillus subtilis inoculant, controlling the temperature to be 28-37 DEG C, stirring and composting for continuous fermentation to obtain the crop and fruit tree fertilizer after the fermentation is completed. The fermented aquatic protein is conducive to the absorption of crops and grape fruit trees, and can quickly restore soil fertility and take an effect for a long time. The preparation method provided by the invention realizes the purpose of secondary comprehensive utilization of wastes, protects the living environment, improves the air permeability, water permeability and the like of soil, realizes the reuse of the soil, and also avoids the addition of a lot of chemical fertilizers. The crop and fruit tree fertilizer can be directly used for fertilization for fruit trees and crops.

Description

technical field [0001] The invention belongs to the technical field of bio-organic fertilizers, and relates to a method for preparing fertilizers for crops and fruit trees. It is a method for preparing fertilizers from biologically fermented aquatic leftovers, and is suitable for fertilizing crops or fruit trees. Background technique [0002] Wastewater from aquatic product processing contains about 0.5-2.0% soluble protein. Taking the surimi production industry as an example, the current annual output of surimi in my country is about 300,000 to 400,000 tons. According to the calculation of about 15 tons of wastewater per ton of surimi, 90,000 to 120,000 tons of water-soluble proteins are lost. The existing domestic technology cannot effectively recover and utilize protein, resulting in a large loss of high-quality protein resources and seriously polluting the environment. [0003] On the other hand, chemical fertilizers are commonly used in my country's agriculture. The ap...

The existing domestic technology cannot effectively recover and utilize protein, resulting in a large loss of high-quality protein resources and seriously polluting the environment

[0003] On the other hand, chemical fertilizers are commonly used in my country's agriculture. The application of a large amount of chemical fertilizers results in poor air permeability and poor reusability of the soil.
