Fast propagation method of winter host moss of Chinese gall aphid

Abstract

The invention relates to a fast propagation method of winter host moss of Chinese gall aphid, comprising the following steps of: selecting a dank forest land as a moss nursery of the winter host moss of the Chinese gall aphid; selecting loose and fertile black soil containing much humus, and blending with 20 percent of screened fired soil ash to prepare nutrient soil; flattening the moss nursery,and dividing into plots; flatly paving non-woven fabrics on the plots; paving the nutrient soil on the non-woven fabrics; completely watering the nutrient soil, and then planting seed mosses; after the seed mosses are planted, covering mulching films on the plots for moisture preservation; constructing a sun-shading net on the moss nursery; uncovering the mulching films after a half month, weeding and removing impurities; and inoculating aphids migrating in autumn after two months. According to the fast propagation method disclosed by the invention, the growth speed and the propagation coefficient of the winter host moss can be greatly increased, and the fast propagation effect of Chinese gall mosses is very outstandingly enhanced.

Description

technical field [0001] The invention relates to a rapid propagation method of the moss which is the winter host of Galla aphid, and is particularly suitable for the rapid propagation method of the moss which is the winter host of the Galla aphid and the gall aphid. Background technique [0002] Gallnut is a gall formed by aphids parasitizing on the compound leaves of the genus Salmonella, Red Bran Poplar, and Green Bran Poplar in the Anacardaceae family. Gallnut production requires three elements of "aphids, moss, and double trees". Due to the limitation of the ecological environment, the productivity of gallnuts in the country is currently low, and the average yield per mu in wild natural conditions is about 1 kg; the average yield per mu in artificially constructed double forests is about 8-15 kg , The technical and economic comparison benefits are low, which seriously affects the production enthusiasm of Beinong. At present, the artificial planting of gallnut in my count...

Problems solved by technology

Gallnut production requires three elements of "aphids, moss, and double trees". Due to the limitation of the ecological environment, the productivity of gallnuts in the country is currently low, and the average yield per mu in wild natural conditions is about 1 kg; the average yield per mu in artificially constructed double forests is about 8-15 kg , the technical and economic benefits are low, which seriously affects the production enthusiasm of Beinong

At present, the artificial planting of gallnut in my country mainly adopts the techniques of "picking and retaining seeds, planting moss to propagate aphids, and artificially hanging bags". The technique of planting moss in pits is labor-intensive and the reproduction coefficient is low (generally 4-5 times), which affects the technical and economic benefits and popularization and application
