Directional luring type soil composting method

Abstract

The invention discloses a directional luring type soil composting method, and belongs to the technical field of soil improvement and repair. A plurality of directional luring forks are directionally put in soil, food luring balls serving as luring earthworms are loaded on the directional luring forks, selected earthworms with vigorous vitality are put into the soil, under the action of the food luring balls, the earthworms can achieve activity foraging in the soil within the range of the buried directional luring forks, so that key plowing and composting of a specific area (such as a rhizosphere range) can be realized according to the requirements of agricultural production, other areas are uniformly subjected to plowing and composting, the problem of large difference of plowing and composting of the same soil of the same crop in some environments is solved effectively to a certain extent, soil plowing and composting comprehensiveness and directionality are easy to achieve, the directional luring fork can be replaced regularly, new food luring balls are loaded after replacement, new earthworms are thrown in at the same time, and the continuous positioning composting improvement ofthe soil is realized.

Description

technical field [0001] The invention relates to the technical field of soil improvement and maintenance, and more specifically relates to a directional-attraction type soil composting method. Background technique [0002] Earthworms are the main animal group in the soil, and they are called "ecosystem engineers". They can affect the soil structure and function through a series of life activities such as defecation, burrowing, and stirring. Darwin once pointed out that "the plow is one of the earliest and best inventions of man, but long before man existed the soil was and will be tilled by the earthworm". Modern research has also proved that earthworms have a great effect on the formation of soil structure (pores and aggregates). Earthworms can swallow soil equivalent to 5-30 times their own weight every day, leaving a large amount of vermicompost accumulated on the soil surface or in the soil. These vermicomposts have a good aggregate structure, which can significantly red...

AI Technical Summary

Problems solved by technology

[0003] In this process, people cannot control the direction and range of earthworm activities, so it is difficult to achieve key plowing and composting in specific areas (such as the rhizosphere) according to the needs of agricultural production

In addition, the characteristics of earthworms tending to fertilizer and water make earthworms more willing to live in areas rich in moisture and organic matter. If the soil fertility and humidity of the same crop are different, this limits the range of earthworm biological activities, making the same The difference between plowing and composting of the same piece of soil for crops gradually increases, making it difficult for the comprehensiveness and orientation of soil composting
