Organic ecological soil conditioner and preparation method thereof

Abstract

The invention belongs to the technical field of crop additives and mainly discloses an organic ecological soil conditioner which is prepared by crop straws serving as a raw material and a preparation method for the organic ecological soil conditioner. The organic ecological soil conditioner is composed of, by weight, 60%-70% of straws which are subjected to fermentation and smashing and 30%-40% of auxiliary materials which are formed by combining animal ripening fertilizers, cake fertilizers, organic micro element fertilizers and strains. The organic ecological soil conditioner and the preparation method thereof have the advantages that by means of the organic ecological soil conditioner, quantity and activity of soil microorganisms are increased, simultaneously when organic substances with high carbon and nitrogen (C / N) ratio are added in the soil, the organic substances have complicated biochemistry reaction with carbon pool and nitrogen pool which originally exist in the soil, the circulation of carbon and nitrogen in the soil can be greatly changed, the soil respiration and CO2 emission are increased, a good temperature effect is provided for growth of crop roots, and the organic ecological soil conditioner has a remarkable improving effect on the soil structure.

Description

technical field [0001] The invention belongs to the technical field of crop additives, and mainly relates to an organic ecological soil conditioner prepared from crop stalks as a raw material and a preparation method thereof. Background technique [0002] In recent years, with the reduction of rural labor force and the change of fuel structure, the amount of discarded crop straw has risen sharply, and the surplus straw has become a major problem in agricultural production. In order to grab farming time and save manpower, farmers often use the method of direct burning in the field to dispose of straw. This not only wastes resources, but also releases a large amount of pollutants that are harmful to the human respiratory tract. The resulting smog leads to the closure of airports and frequent traffic accidents on highways, which has a great negative impact on people's production and life. In addition, burning straw also burns away part of the organic matter in the soil; the hi...

Problems solved by technology

This not only causes a waste of resources, but also open-air burning of straw will release a large amount of pollutants that are harmful to the human respiratory tract. The smog formed will lead to the closure of the airport and frequent highway traffic accidents, which will have a great negative impact on people's production and life.

In addition, burning straw also burns away part of the organic matter in the soil; the high temperature generated during the burning of straw has a great killing effect on soil microorganisms; the evaporation of soil moisture and the destruction of soil structure caused by burning straw are not conducive to survival of soil microbes

Over time, it will inevitably cause soil compaction, decline in fertility, deterioration of soil ecosystem, and greatly reduce the quality of agricultural products.
