Abstract

The comprehensive forest and silkworm running method relates to forestry technology and raising technology. The method includes chopping natural inferior secondary oaks, growing new oaks to form oak forest, planting shading needle trees under oak tree crown to form artificial compound storied forest, raising oak silkworm on the oak trees while cultivating artificial young forest. The method of the present invention has fast tree seedling growth, and can raise great amount of oak silkworm.

Description

Comprehensive producing method for forest and silk worm combined running

Technical field:

The present invention relates to the forestry plantation, support the planting technology field, is a kind of comprehensive producing method for forest and silk worm combined running.

Background technology:

At the Northeast China wide geographic area the secondary toothed oak wood of a large amount of natural low-qualitys woods is arranged, at present low-quality toothed oak wood woods there is not desirable science management style, it is the original single transformation production method of fostering, with the artificial sapling of toothed oak wood felling back plantation, should avoid the high light direct irradiation as coniferous tree such as Korean pine, dragon spruces, need cover shade, the tending [after young plantation complex management, and it is single to cultivate varieties of plant, and economic benefit, ecological benefits, social benefit are undesirable.

Summary of the invention:

The technical issues that need to address of the present invention provide and a kind ofly convenient manage, can increase economic efficiency, the comprehensive producing method for forest and silk worm combined running of ecological benefits, social benefit.

The present invention utilizes toothed oak tree growth cycle short, and the characteristics that primary growth is fast make it germinate young toothed oak tree in the primitive root evil after the felling, form the germinating toothed oak woods once more, build needle and cover shady seeds under toothed oak tree young growth hat, as Korean pine, dragon spruce etc., artificially form irregular forest.Produce simultaneously in tending [after young plantation, natural germinating children toothed oak tree is selected excellent managing and protecting, make it recover natural toothed oak woods group again, put tussah in a suitable place to breed then on the toothed oak tree, hat is fostered the young plantation down, realizes forestry, the silkworm comprehensive production and operation mode of common development already.

Further technical scheme of the present invention is as follows:

1, cut down whole toothed oaks trees of natural secondary toothed oak wood woods growth winter, when treating that spring, the primitive root evil was germinated young toothed oak sapling, place, the vacant lot plantation needle sapling between the former toothed oak tree root evil of forest land.

When 2, the toothed oak sapling grows into 20 to 50 cm heights, the toothed oak tree is selected excellent managing and protecting.

When 3, the toothed oak sapling grows into 50 to 100 cm heights, on the toothed oak tree, put tussah in a suitable place to breed.

Wherein said plantation needle sapling spacing can be two meters and take advantage of two meters, per hectare is planted 2,000 strains, as timber forest, the sapling spacing can be five meters and take advantage of ten meters that per hectare is planted 600 strains, as seed orchard, described select excellent manage and protect the young toothed oak tree that is meant germinating select individual growth preferably treelet select and remain, outdoor rearing of tussah silkworm amount is five hectares and puts a silkworm, and one is silkworm 150,000, is national standard.This production method is suitable for the Korean pine seed orchard most.

The present invention has protected biotic population and diversity of organism, has cultivated the high-quality theropencedrymion reserve forest resources and fast-growing and high-yield plantation, makes forest tree resource obtain the optimum organization configuration.The tussah excreta has increased the forest land organic manure, and quickening can have litter horizon to decompose, and has strengthened soil permeability and has made artificial treelet seedling healthy growth under the crown canopy, provides nutritional condition for cultivating the high-quality woods.The toothed oak tree is put silkworm in a suitable place to breed and can obtain high economic benefit in a short time.

The conifer seedling of the inventive method plantation highly increases by 13 centimeter than the nursery stock of existing method plantation every year, and per hectare is put silkworm in a suitable place to breed and obtained 2,100 yuan of direct economic benefits, saves and fosters 2,000 yuan of young growth production costs, and the tending [after young plantation management is simple.

Embodiment:

Select the five hectares of secondary toothed oak wood of natural low-quality woodss at Chinese Changbaishan area, all cut down winter, when treating that spring, the primitive root evil was germinated young toothed oak sapling, place, vacant lot between the former toothed oak tree root evil of forest land is plantation 10,000 strain Korean pine sapling timber forest evenly, when treating that the toothed oak sapling grows into 40 cm heights, toothed oak tree is selected excellent managing and protecting, when treating that the toothed oak sapling grows into 70 centimetres and above height, on the toothed oak tree, put a tussah in a suitable place to breed.

Select the ten hectares of secondary toothed oak wood of natural low-quality woodss at Chinese Changbaishan area, all cut down winter, when treating that spring, the primitive root evil was germinated young toothed oak sapling, place, vacant lot between the former toothed oak tree root evil of forest land is plantation 6,000 strain Korean pine saplings evenly, as seed orchard, when treating that the toothed oak sapling grows into 40 cm heights, the toothed oak tree is selected excellent managing and protecting, when treating that the toothed oak sapling grows into 70 centimetres and above height, on the toothed oak tree, put two tussahs in a suitable place to breed.

Claims

1, a kind of comprehensive producing method for forest and silk worm combined running, it is the secondary toothed oak wood of the natural low-quality of felling woods, make it germinate young toothed oak tree in the primitive root evil, form the germinating toothed oak woods once more, under toothed oak tree young growth hat, build needle and cover shady seeds, artificially form irregular forest, make it recover natural toothed oak woods group again, then on the toothed oak tree, put tussah in a suitable place to breed, foster the young plantation under the hat.

2, according to claim 1 described comprehensive producing method for forest and silk worm combined running, scheme is as follows:

(1), cut down whole toothed oaks trees of natural secondary toothed oak wood woods growth winter, when treating that spring, the primitive root evil was germinated young toothed oak sapling, place, the vacant lot plantation needle sapling between the former toothed oak tree root evil of forest land;

(2), when the toothed oak sapling grows into 20 to 50 cm heights, the toothed oak tree is selected excellent managing and protecting;

(3), when the toothed oak sapling grows into 50 to 100 cm heights, on the toothed oak tree, put tussah in a suitable place to breed.
