Abstract

This invention provides about the cultivation of weeping willow, the breeding districts includes Beijing, Shandon, Shanks, Heber, Kiangs, Guizhou, Hubei, Henan, Inner Mongolia, and Northeast area. It adopts the wild weeping willow from the Jilin district as the paternal and small black poplar from White Town as maternal, adopts stick bud graft and insert bark graft to crossbreed, then abandons the pseudo strain from the filial generation and retains the true cross strain, observe the later generation for three continuous years, and the single strain with high quality can be promoted when they are stable. The weeping willow cultivated by this method is a kind of ornamental which beautify the environment, and it also has excellent features and high economic values of common poplar.

Description

technical field [0001] The invention belongs to a method for cultivating inverted poplars. Background technique [0002] Poplar is widely distributed in my country. Poplar has the characteristics of fast growth in early stage, strong adaptability, many varieties and easy reproduction. In my country, poplars are mainly used to build shelter forests and timber forests. The purpose of cultivating fine varieties of poplars is mostly to allow poplars to quickly produce timber, shorten the rotation period, and increase the economic value of timber production and quality. However, there are few studies on the beautification of poplar, and there are few breeding studies that make poplar have higher economic value and beautify the environment. With the continuous development of my country's national economy, new breakthroughs have been made in my country's greening and beautifying cause, but there are few species of greening and beautifying trees. This traditional greening and beau...
