Abstract

The invention discloses a method for improving the nutrient supply of female flower branches in artificial cross-breeding of black poplar. According to the technical link of the hybridization operation, the method comprises the steps of cultivating the nutrient supply seedlings from the female flower branches (that is, the rootstocks of the flower branches) and the nutrient supply seedlings from the female flower branches. The early management, hydroponic management of flowering branches, connection of female flowering branches and rootstocks, management of nutrient supply seedlings of female flowering branches, and hydroponic management of female flowering branches have been integrated and improved, so as to improve the hybridization of poplar cutting branches and hydroponics. Breeding goals for seed set rate and quality. Compared with the conventional method, the application of the method of the present invention not only has good seed quality, but also improves the seed setting rate, and the artificial cross-breeding effect of applying the method of the present invention is remarkable.

Description

technical field [0001] The invention belongs to the technical field of cross-breeding of forest trees, and relates to a method for improving the nutrient supply of female flower branches in artificial cross-breeding of black poplar, in particular to a method for improving the seed setting rate and quality of hydroponic hybrid breeding of poplar cutting branches by improving the nutrient supply of female flower branches . Background technique [0002] Poplar hybrid breeding is the most important way to improve poplar. Most of the domestic and foreign cultivars are selected through this way, because hybrids can have the required good quality and adaptability. In addition to a small number of natural hybrids in nature, artificial hybridization is the most important means to obtain hybrids. It is divided from the environment in which the female parent of the seed develops: one is artificial hybridization on an outdoor big tree, and the other is artificial hybridization indoors ...
