Problems solved by technology

In addition, due to the slow speed of fertilizing nitrogen nutrients, organic fertilizers often cannot meet the needs of crop growth. In order to meet the needs of crop growth, a large amount of organic fertilizers are applied at one time, which also causes environmental nitrogen leaching, NOx release, NH 3 release, especially the hazards of heavy metal pollution and salt accumulation
[0005] On the other hand, because a large amount of straw and tail vegetables cannot be decomposed in a short time after returning to the field, a large amount of straw is burned.
The tail vegetables are discarded everywhere, causing environmental pollution

Abstract

The invention discloses a preparation method of an organic fertilizer and a preparation method of an organic-inorganic biochar compound formula fertilizer. The preparation method of the organic fertilizer provided by the invention comprises the following steps: (1) mixing organic matters and biochar to obtain a premix; (2) controlling the water content of the premix to be 10%-50%; (3) adding an organic matter degrading enzyme into the premix treated in the step (2); (4) adding a biodegradation agent into the mixture obtained in the step (3); and (5) carrying out composting fermentation on the mixture obtained in the step (4) to obtain the organic fertilizer after the fermentation is finished. According to the compound formula fertilizer disclosed by the invention, plant-source and animal-source organic matters are mixed and fermented, and the raw materials are subjected to innocent treatment to form biochar, so that the adsorption effect of the biochar is exerted, and a clean organic fertilizer is produced; nitrogen, phosphorus and potassium fertilizers are balanced and reasonably formulated according to organic matters from different sources, so that the fertilizer efficiency is maximized.

Description

[0001] This application is a divisional application with an application date of September 27, 2016, an application number of 201610855065.3, and the title of the invention "An organic-inorganic biochar compound fertilizer and its preparation method". technical field [0002] The invention belongs to the technical field of compound fertilizer preparation, in particular to a preparation method of an organic fertilizer and a preparation method of an organic-inorganic biochar compound formula fertilizer. Background technique [0003] Fertilizer is one of the material bases of agricultural production. Before the world's green revolution, organic fertilizers were the mainstream of fertilizers. After the Green Revolution, chemical fertilizers replaced organic fertilizers, which increased yields but also caused soil fertility degradation and environmental problems. my country is facing the situation of soil fertility degradation, low efficiency of chemical fertilizer utilization, s...
