A method for increasing the yield of gallnut by using non-woven fabric as substrate to plant moss and raise aphids

Abstract

The invention relates to a method for increasing gallnut yield by cultivating moss and culturing aphids on non-woven fabric as a matrix, and belongs to the technical field of cultivation of economic forests. According to the method disclosed by the invention, according to the biological characteristics of good winter host moss for gallnut aphids, by taking schlechtendalia chinensis production as an example and taking the non-woven fabric as a carrier, the moss is cultivated and the aphids are cultured on the non-woven fabric matrix, and artificial management and culture is performed through a gallnut aphid scattering method or by inoculating gallnut aphids and autumn migrants, therefore the survival rate of overwintering aphids is increased; through production application in gallnut producing areas, such as Wufeng Tujia autonomous county, Zhushan county in Hubei province, the density of the overwintering aphids on the moss reaches 21 thousand per square meter on average, and the highest gallnut yield of a three-year-old gallnut forest is 82.5 kilograms per mu, which has a remarkable yield-increasing effect in comparison with the yield 30 to 50 kilograms per mu of traditional forest moss cultivation. The non-woven fabric adopted by the method disclosed by the invention is low in cost and small in size; moreover, the aphids and the moss are light in weight, firm as a whole, and easy to move; the aphids can be conveniently collected or scattered, and a better aphid collecting effect can be achieved; the method is simple and convenient in management and easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of cultivation of economic forests, and in particular relates to a method for artificial moss cultivation of galla aphids, collection of aphids and scattering in forests to increase the yield of galla aphids. Background technique [0002] Gallnut is a kind of gall formed by some aphids feeding on the leaves of Salmonella, Populus chinensis and Populus spp., stimulating the proliferation and expansion of leaf tissue cells. The main component of gallnut is tannic acid, which has the functions of astringing the lungs to stop bleeding, heat dissipation and detoxification, detoxification and anti-cancer, healing sores and swelling, etc. Gallnut has been used in China for more than 2,000 years, and its traditional uses are mainly in traditional Chinese medicine and textile industries. With the development of modern science and technology, gallnut has become an important raw material for extracting a series of chem...

Problems solved by technology

Soil substrate moss has disadvantages such as difficulty in moss block transportation and aphid collection, fast growth of weeds, high management cost, etc. It is difficult to realize factory production and management, which seriously restricts the promotion and application of Galla gall artificial cultivation technology

Although the prior art also discloses the method of utilizing soilless plant moss to raise aphids, for example, the patent application whose application number is 201410319188.6 discloses a kind of method for soilless plant moss to raise aphids to increase the yield, and the substrate for planting moss in this method is Tiles or bricks, but we know that tiles or bricks are fired from clay, which are heavy, bulky, fragile, and difficult to carry. Planting moss on tiles or bricks cannot achieve large-scale migration Generally, aphids can only be collected on the spot, so this method has not completely overcome the defects of moss block handling and aphid collection difficulties in traditional substrates.
