Cultivating method of cercis canadensis grafting root stocks

Abstract

The invention discloses a cultivating method of cercis canadensis grafting root stocks. The cultivating method comprises the following steps: 1) selecting seeds; 2) performing land preparation; 3) preparing a seedbed; 4) sowing the seeds; 5) performing final-period management after sowing; 6) cutting scion bud slices; 7) cutting rootstock interfaces; 8) performing grafting; 9) treating grafted seedlings; 10) checking the survival rate; 11) performing complementary grafting; and 12) untying the grafted seedlings. The cultivating method disclosed by the invention aims to solve the problems of low survival rate and non-uniform seedling growth in the grafting process of the cercis canadensis at present, so that a new grafting method is provided, and by adopting the new grafting method of the invention, the survival rate of the grafted seedlings can be greatly improved, the growth vigor of the grafted seedlings is good, the grafted seedlings can keep good properties of a parent tree, are high in adaptability, can grow vigorously, and have developed root systems, and moreover, the method disclosed by the invention is simple and convenient and is low in cost.

Description

technical field [0001] The invention relates to a method for cultivating rootstocks of Bauhinia Bauhinia grafting. Background technique [0002] Purple-leaf Canadian Bauhinia is also known as Purple-leaf Canadian Bauhinia and Red-leaf Canadian Bauhinia (new high-grade colorful leaf seedlings), and the adult plant height is 7 to 15 meters. In early spring, the first leaves bloom, the corolla is flat, round, reddish-purple, clustered or in racemes, and the flower clusters are luxuriant and eye-catching. Purple-leaf Canadian Bauhinia can not only watch flowers but also watch leaves. It has purple-red heart-shaped leaves all year round. Bauhinia canadensis is the same species as Chinese Bauhinia, a small tree. Native to the United States, it belongs to the Fabaceae Bauhinia genus. The height of the tree is 6-9 meters, and the crown width is 8-11 meters. The leaves are brown to purple-red, turning yellow in autumn. The leaves are heart-shaped, broad-ovate, and cuneate at the ...
