A cultivated land remediation device based on the principle of microbial remediation

Abstract

The invention discloses a cultivated land restoration device based on the principle of microbial restoration, which belongs to the field of cultivated land restoration. It is a cultivated land restoration device based on the principle of microbial restoration. The microorganisms in the microbial cultivation device of this proposal will produce anaerobic composting during the natural growth process process, and produce a large amount of waste gas from metabolism. With the increase of carbon dioxide and other waste gas content in the microbial culture device, the separation membrane will gradually expand, and even part of the separation membrane will be pushed out of the screen frame and contact with the push plate until the puncturing needle passes through the passage. The hole punctures the separation membrane, and the fermented fertilizer produced by the anaerobic composting process in the separation membrane will flow out of the separation membrane, flow into the soil through the bottom plate and the soil-breaking drill bit, and the liquid fertilizer will quickly spread in the soil to realize the restoration of the soil. It can effectively avoid the follow-up residual problems of traditional chemical fertilizers and bioremediation technologies, and is less prone to derivative problems caused by remediation technologies, reducing environmental pollution.

Description

technical field [0001] The invention relates to the field of cultivated land restoration, and more specifically relates to a cultivated land restoration device based on the principle of microbial restoration. Background technique [0002] The soil on which food is grown is usually called cultivated land, which is the basic resource and condition for human beings to survive. The output of cultivated land resources is closely related to the soil fertility of cultivated land. Fertile land usually has better food output, but food The fertility absorbed from the land during the growth process is much higher than the natural recovery speed of the land fertility. Therefore, no matter how fertile the land is, after a long time of cultivating a kind of food, the fertility and food output will usually decrease. , while the ancient people mainly improved soil fertility and increased the grain output of cultivated land through rotation or fallow. [0003] With the development of modern...
