Method for rapidly improving organic agricultural soil fertility

Abstract

The invention relates to the field of organic agricultural production and soil fertility improvement, in particular to a method for rapidly improving organic agricultural soil fertility and application thereof. The method for rapidly improving organic agricultural soil fertility, provided by the invention, is that a compound conditioner is applied to the soil and earthworms are released to the soil, wherein before the compound conditioner is applied and the earthworms are released, the soil is required to meet the following conditions: 1), the soil moisture content is kept to be 30%-50%, and 2), soluble-salt content of the soil is kept to be lower than 0.04%; 300-500 kg of the compound conditioner is applied to per mu of soil; 30-50 kg of the earthworms are released to per mu of the soil. By adopting the method provided by the invention, the number of earthworms in a farmland is increased greatly, the activity of earthworms in the farmland is improved greatly, soil rejuvenation and fertility improvement rate is increased, microbial diversity of the soil environment is increased, soil quality is improved, crop quality and yield are improved and sustainable development of organic agriculture is realized.

Description

technical field [0001] The invention relates to the field of organic agricultural production and fertilization, in particular to a method for rapidly improving the soil fertility of organic agricultural production farmland and its application. Background technique [0002] Agricultural development has basically gone through several stages of development, including traditional agriculture, green revolution, and oil agriculture. Petroleum agriculture has made a great contribution to solving the serious shortage of human food, but it has also brought a series of problems such as the reduction of cultivated land, the decline of cultivated land quality, environmental pollution, food safety, biodiversity reduction, resource depletion, etc., which affect the sustainable development of human beings on the earth. serious problem. In the high-intensity "modern" farming (such as extensive use of chemical fertilizers and pesticides), problems such as reduced soil compaction, increased ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a method of using earthworms to quickly improve the soil fertility of organic agriculture and improve the physical and chemical properties of farmland soil, to solve the problem of slow improvement of soil fertility during the conversion period of organic production bases and in the subsequent production process, and to improve soil structure and enhance Soil biological activity and reducing soil harmful microorganisms (such as Fusarium oxysporum, Fusarium wilt, etc.), improving the ecological environment of farmland
