Problems solved by technology

"At present, the quality of cultivated land in our country is low, and the problems of cost and pollution are serious, and the cultivated land is decreasing year by year. If the red line of arable land per mu cannot be ensured and the quality of arable land cannot be solved, it will inevitably threaten the national food security.

Embodiment 1

[0024] A method of utilizing earthworms to carry out soil restoration, comprising the following steps:

[0025] (1) Select the species of earthworm

[0026] There are many types of earthworms, and different types of earthworms have different tolerances to pollution levels. Choose the appropriate type of earthworm according to the soil condition;

[0027] (2) Artificial breeding of earthworms

[0028] Wild earthworms are limited by temperature, soil moisture and environment, and their reproduction is slow, so earthworms need to be cultured artificially

[0029] 1) Build medium

[0030] Livestock and poultry manure, plant straw or sludge are used as raw materials to form a culture medium. The culture medium is 10m-100m long and 1m-3m wide, and the culture medium is covered with a layer of straw;

[0031] 2) putting the selected earthworms into the culture medium;

[0032] 3) Control the temperature of the culture medium at 6-15C°;

[0033] 4) Sprinkle water regularly in the...

Abstract

The invention discloses a method for remediating soil by earthworms. The method comprises the following steps: (1) selecting the earthworm species; (2) artificially breeding the earthworms; (3) putting the earthworms collected from a breeding factory into the soil needed to be improved. According to the method, the number of the earthworms is increased by artificially breeding the earthworms, the bred earthworms are put into the soil needed to be improved, and the soil is quickly improved by earthworm manure generated by the earthworms in a normal metabolic process; the method is economic, safe and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, and specifically relates to a soil restoration method using earthworms. Background technique [0002] Earthworms play a very important role in terrestrial ecosystems. They participate in the decomposition of soil organic matter and nutrient cycling, and their feeding activities indirectly mechanically turn the soil, and transform the structure, air permeability and water permeability of the soil , so that the soil matures rapidly. The vermicompost produced by earthworms during normal metabolism contains a large number of microbial communities and complex organic chemical components, and has a special physical structure, so it plays a very important role in improving various physical and chemical structures of the soil and improving soil fertility. Known as "the plowman of agriculture" and "the expert of improving the soil". With the development of industrial processes and the continuo...
