Embodiment 1-9

[0030] Feeding conditions:

[0031] Control the soil moisture content under the forest to 20%-80%;

[0032] The drainage and irrigation channels between the tree ridges under the forest are smooth;

[0033] Dig 0.5-1.0 meters wide, 0.2-1.0 meters deep, and 0.5-3.0 meters away from the tree pits every 5-10 meters between the tree ridges. When it rains, it is used for earthworms to escape, and the soil pit can be placed with organic fertilizers for feeding earthworms, and the fertilizers can be absorbed and utilized by trees.

[0034] The weight of earthworms per mu of forest land is 100-300kg. The sources of earthworm feed are shown in Table 1, mainly dead branches and leaves, crop stalks, manure, livestock and poultry manure, commercial organic fertilizers or interplanting green manure, pasture, etc. For the output of woodland earthworms, the application amount of organic fertilizer per mu of forest land is 4000 kg of unfermented livestock and poultry manure, or 2000 kg of o...

Abstract

The invention provides a method for raising earthworms in forest according to the features of the ecological environment in forest and the law of earthworm growth in combination with the demands of ecological, economic and social development at present. Earthworms are positioned into the forest and then raised in a scattered way in order to create an appropriate raising environment in the forest.On the basis of the advantages of high economic benefit, simple management requirement, easy operation and mastering of technology, strong operability of in-forest production and good ecological benefit, earthworms are positioned into the forest for production, and simultaneously, the invention also provides a technology for raising earthworms in forest. Field tests prove that the technology can improve the survival rate and the yield factor of earthworms and has a remarkable effect on soil improvement.

Description

technical field [0001] The invention belongs to the economic development mode and supporting technology of the ecological industry under the forest, in particular to the breeding technology for producing a kind of high value-added earthworm under the forest. Background technique [0002] Strengthening ecological construction and maintaining ecological security are common themes faced by mankind in the 21st century. Forestry construction is the main body of ecological construction. The goal of my country's ecological construction is: strive to make my country's forest coverage rate reach more than 19% by 2010; make the forest coverage rate reach more than 23% by 2020; make the forest coverage rate reach and stabilize at more than 26% by 2050 , basically achieve beautiful mountains and rivers, the ecological situation has entered a virtuous cycle, the contradiction between supply and demand of forest products has been alleviated, and a relatively complete forest ecological sys...
