Embodiment Construction

[0027] The technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The present embodiment provides a kind of method that improves the nutrient supply of poplar artificial cross breeding female flower branch, to improve seed setting rate and quality of poplar cut branch hydroponic cross breeding, realize through the following steps:

[0029] 1) Collection of flower branches: The collection of flower branches should be carried out before the sap flows. The collection time in North China is generally at the end of January and the beginning of February...

Abstract

The invention discloses a method for improving nutrient supply of a Populus nigra artificial hybridization breeding female flowering branch. According to the technical link of a hybridization operation, the method carries out integrated improvement and promotion from the links, including breeding of a female flowering branch nutrient supply seedling (i.e., the inarching stock of the flowering branch), early stage management of the female flowering branch nutrient supply seedling, flowering branch hydroponic culture management, inarching of the female flowering branch and the stock, management of the female flowering branch nutrient supply seedling, hydroponic culture management of the female flowering branch and the like, and therefore, a goal of improving the seed setting percentage and the quality of Populus L. cutting branch hydroponic culture hybridization breeding is achieved. Compared with conventional methods, utilization of the method disclosed by the invention is characterized in that the quality of seeds is good, the seed setting percentage is improved, and an effect is obvious when the method disclosed by the invention is applied to Populus nigra artificial hybridization breeding.

Description

technical field [0001] The invention belongs to the technical field of hybrid breeding of forest trees, and relates to a method for increasing the nutrient supply of poplar artificial hybrid breeding female flower branches, specifically a method for improving the seed setting rate and quality of poplar cut branch hydroponic hybrid breeding seeds by increasing the nutrient supply of female flower branches . Background technique [0002] Poplar hybrid breeding is the most important way to improve poplar. Most of the cultivated varieties at home and abroad are selected through this way, because the hybrids can have the required excellent quality and adaptability. In addition to a small number of natural hybrids in nature, artificial hybridization is the most important means of obtaining hybrids. Divide from the environment where the female parent of seed development is located: a kind of is the artificial hybridization on outdoor big tree, and another kind is indoor artificial...
