Problems solved by technology

[0007] The purpose of the present invention is to provide a kind of biological farming technology that can replace mechanized farming in farmland, that is, earthworm culture and biological farming technology in farmland, to solve the problems of energy shortage caused by mechanization, low economic benefits, and non-point source pollution caused by chemical fertilizers. Improve soil structure, enhance soil biological activity and increase soil fertility, which can reduce the amount of chemical fertilizers and improve the ecological environment of farmland

Embodiment 1

[0029] Earthworm feeding conditions:

[0030] Soil moisture content is kept at 30-70%;

[0031] Smooth drainage and irrigation between crop ridges;

[0032] Each mu of land between ridges or fields should be 0.2-1.0m higher than the cultivated land, with an area of ​​5.0-15.0m 2 There are 5-15 turtle-shaped soil slopes on the left and right, so that earthworms can escape when it rains;

[0033] Earthworms can be placed with a weight of 100-1000kg per mu;

[0034] Feed sources for earthworm feeding are mainly crushed crop stalks, manure, livestock and poultry manure, commercial organic fertilizers, intercropping (intercropping) crops, planting green manure or pasture. In addition to returning crop straw to the field, apply more than 1,000kg of organic fertilizer per mu per year, and apply it according to the seasonal crop stubble arrangement.

[0035] The collection method is to use fried bran to add a small amount of fried bean cake powder, and sprinkle it on the soil surf...

Abstract

The invention relates to a farmland earthworm cultivation and organism farming method established according to the agricultural production, the soil living characteristics of earthworms and the requirement of modern agriculture ecological environment construction, in particular to a method for carrying out earthworm cultivation and organism farming under a non-crop rotation condition of planting and cultivating. Earthworms are cultivated under the environment conforming to the following cultivating conditions of: keeping the water content of farmland soil to be 20-70 percent; constructing inter-ridge irrigation and drainage channels; building a proper quantity of whaleback-shaped soil slopes used for escaping for the earthworms during raining between ridges or in fields; and putting earthworm seeds into the farmland and cultivating. In the invention, the earthworms are introduced to farmland production based on the characteristics of agricultural economic benefit improvement, agricultural environmental pollution reduction, simple and convenient management requirement, and the like, and meanwhile, proved by field tests, the proposed farmland earthworm cultivation and organism farming technology can improve the soil quality, enhance the soil bioactivity and improve the yield and the quality of agricultural products and the agricultural ecological environment.

Description

technical field [0001] The invention belongs to animal breeding and agricultural farming, in particular to a technology for realizing farmland soil biological farming under the condition of non-rotation of farmland crop planting and earthworm culture. Background technique [0002] As an ancient organism, earthworms have existed in nature for 600 million years. They are one of the animal groups with the largest biomass in soil and play an irreplaceable role in maintaining soil ecosystem functions. Earthworms can loosen the soil, increase soil organic matter and improve the structure, and can also promote acidic or alkaline soil to become neutral soil, increase phosphorus, potassium and other quick-acting components, making the soil suitable for the growth of crops. Because earthworms are rich in protein, they can be used as feed for livestock, poultry and aquaculture to increase production. Earthworms also occupy a certain position in pharmacology. They are common Chinese he...
