Abstract

The invention belongs to a method for cultivating drooping poplar trees. Breeding is performed in Beijing, Shandong, Shanxi, Hebei, Jiangsu, Guizhou, Hubei, Henan, Inner Mongolia and northeast China, wild drooping poplar trees are used as male parents, Populus xiaohei is used as female parents, patch budding and bark grafting are adopted for hybridization breeding, hybrid generations are selected, pseudo-hybrid plants are removed after grafting, hybrid plants are reserved, continuous observation for 1 to 3 years is performed, and superior individual plants which grow vigorously and are good in quality can be popularized for planting after the plants become stable. The drooping poplar trees cultivated by adopting the method have good viewing and environment beautifying effects, and simultaneously have excellent characteristics of poplar trees and greater economic value.

Description

technical field [0001] The invention belongs to a method for cultivating inverted poplars. Background technique [0002] Poplar is widely distributed in my country, and poplar has the characteristics of fast growth in the early stage, strong adaptability, many varieties, and easy reproduction. In my country, poplar is mainly used to build shelterbelts and timber forests. The purpose of cultivating fine varieties of poplars is mostly to allow poplars to grow quickly, shorten the rotation period, and improve the economic value of timber output 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 better beautify the environment. Along with the continuous development of my country's national economy, my country's greening and beautifying cause has had new breakthrough, but greening and beautifying tree species is few, and greening tree mainly contains pines and cypresses, ...
