Environment-friendly organic fertilizer for improved saline alkali soil and preparation method of fertilizer

Abstract

The invention discloses an environment-friendly organic fertilizer for improved saline alkali soil and a preparation method of the fertilizer. The environment-friendly organic fertilizer is prepared by composting and fermenting, by weight, 10-20 parts of animal carcasses obtained after high temperature sterilization, 5-10 parts of plant straw, 15-30 parts of livestock excrement and 1-5 parts of composite decomposing microbial inoculums. The soil alkalinity can be effectively lowered, the nutrient content of saline alkali soil is increased, characteristics of the saline alkali soil are improved, and the saline alkali soil is improved conveniently; the handling method is mature, the technology is stable, and it is ensured that carcasses obtained after animals are dead are effectively handled, and environmental protection is achieved.

Description

technical field [0001] The invention relates to organic fertilizer technology, in particular to an environment-friendly organic fertilizer for improving saline-alkali soil and a preparation method thereof. Background technique [0002] The corpses of dead animals, no matter whether they died normally or died of epidemic diseases, often carry a variety of germs. If they are not handled or handled improperly, the corpses will quickly decompose and rot, giving off odor, causing pathogenic microorganisms to pollute the air, water and soil , affecting people's living environment, causing the spread and spread of the disease, and people who have direct or indirect contact with it may be infected. At present, there are animal corpses that are used to prepare organic fertilizers after high-temperature biodegradation, which can promote a virtuous cycle of agricultural and animal husbandry production, protect the environment, and prevent pathogenic microorganisms from polluting air, w...

Problems solved by technology

[0002] The corpses of dead animals, no matter whether they died normally or died of epidemic diseases, often carry a variety of germs. If they are not handled or handled improperly, the corpses will quickly decompose and rot, giving off odor, causing pathogenic microorganisms to pollute the air, water and soil , affecting people's living environment, causing the spread and spread of the disease, and people who have direct or indirect contact with it may be infected

At present, there are animal corpses that are used to prepare organic fertilizers after high-temperature biodegradation, which can promote a virtuous cycle of agricultural and animal husbandry production, protect the environment, and prevent pathogenic microorganisms from polluting air, water and soil, affecting people's living environment, and causing diseases. Propagation and spread, and the organic fertilizer prepared after high-temperature biodegradation of animal carcasses can effectively reduce the alkalinity of the soil, increase the nutrient content of the saline-alkali soil, improve the characteristics of the saline-alkali soil, and benefit the saline-alkali soil improvement, but the treatment method is still immature and the process is unstable, which affects people's effective treatment of dead animals and environmental protection
