Vegetable earthworm cultivation ecological system for overcoming soil salinization and continuous cropping obstacles

Abstract

The invention discloses a vegetable earthworm cultivation ecological system for overcoming soil salinization and continuous cropping obstacles. The vegetable earthworm cultivation ecological system comprises a plurality of vegetable planting ditches, multiple earthworm breeding ditches, a fermentation tank and earthworm breeding net cages. The plurality of vegetable planting ditches and the plurality of earthworm breeding ditches are arranged alternatively, and an operation space is formed between one vegetable planting ditch and one earthworm breeding ditch which are adjacent to each other. The fermentation tank is arranged near the plurality of vegetable planting ditches, and organic waste is contained in the fermentation tank. The earthworm breeding net cages are filled with earthworm breeding substrates, the earthworm breeding substrates are prepared by mixing a fermentation product of the organic waste in the fermentation tank with soil, and earthworms are put into the earthworm breeding net cages; and the plurality of earthworm breeding net cages are placed in each earthworm breeding ditch. According to the system, low-cost resource utilization of organic waste treatment is achieved, continuous cropping obstacles and salinization obstacles are overcome, organic circulation of vegetable production and efficient earthworm breeding are combined, and multiple effects and high-benefit output are achieved.

Description

technical field [0001] The invention relates to the technical field of ecological agriculture, in particular to a vegetable earthworm cultivation ecosystem for overcoming soil salinization and continuous sitting obstacles. Background technique [0002] The resource utilization of agricultural waste (including livestock and poultry manure, crop straw, etc.) has realistic and far-reaching significance for improving the agricultural ecological environment and promoting the sustainable development of agriculture. Earthworms are saprophytic animals that feed on organic waste and can transform organic waste into fertile organic fertilizers, promoting the virtuous cycle of materials and energy flow in the ecosystem. Earthworms are called "ecosystem engineers" and can improve soil and increase soil fertility. Existing studies have shown that earthworms can improve wetland water quality, enhance the photosynthetic activity, density and biomass of wetland plants, and enable them to a...

Problems solved by technology

[0003] Vegetables are an indispensable agricultural and sideline product for urban residents. During the vegetable planting process, there will be obstacles to continuous cropping and salinization, resulting in a decline in the quality of vegetables
