Facility and method for combining horticultural crop cultivation with earthworm breeding

Abstract

The invention relates to a facility and method for combining horticultural crop cultivation with earthworm breeding. Firstly, soil preparation is conducted in a three-layer stepped structure, ridges and rectangular pieces of a land in a field are covered with black mulching films, dried cow dung feed is stacked on the rectangular pieces of the land in the field to form a long-strip earthworm breeding bed, and the upper portion of the bed is covered with a straw curtain or a black sunshade net; a two-way drip irrigation way of an adjustable water dropper is adopted, drip irrigation and humidification are conducted on horticultural crops and the earthworm breeding bed respectively, the functions of horticultural crop cultivation and irrigation, earthworm breeding and organic fertilizer production are achieved, meanwhile an exudate nutrient solution produced by wormcast due to irrigation and rain is an organic liquid fertilizer needed by horticultural crop growth, thus the organic fertilizer is additionally applied, four actions including irrigation, cultivation, fertilizer production and fertilizer application are combined, the work efficiency is improved, the concept of ecological cycle is achieved, resource utilization of feces is achieved, the ecological environment is effectively protected, and the requirement of ecological green development is met.

Description

[0001] Technical field: [0002] The invention relates to the technical field of combination of planting and breeding, in particular to a method for combining high-efficiency horticultural crop cultivation and earthworm cultivation and the production of biomass organic fertilizer. [0003] Background technique: [0004] In recent years, with the country's vigorous advocacy of ecological agriculture, the concept of combining planting and breeding with ecological recycling is more and more in line with the future development direction of agriculture. Feeding earthworms with feed-based cow dung can not only reproduce a large number of new earthworms, but also produce As an organic fertilizer, vermicompost can improve soil structure and prevent soil compaction due to its aggregate structure. It has a large amount of biomass humic acid and can repair soil polluted by heavy metals. The combination of drip irrigation technology and plastic film mulching is applied to earthworm breed...

AI Technical Summary

Problems solved by technology

In the production process, if earthworms are cultivated directly around the horticultural crops without additional facilities, the stress on the horticultural crops will be great, and the initial growth of the horticultural crops will be affected. At the same time, it is inconvenient to collect earthworms and separate the vermicompost, which is not efficient. Characteristics of the sexual synthesis cycle
