Problems solved by technology

However, the existing kapok grafting methods are all single-stem grafting methods, which have the following disadvantages: 1) low survival rate: the survival rate of single-stem grafting is only 70-80%; 2) high cost: once the single-stem grafting fails, the rootstock will be damaged 3) High partial crown rate: even if single-stem grafting survives, it is

Example Embodiment

[0030] Example 1: A grafting method to correct the crown bias of grafted kapok seedlings

[0031] 1) Rootstock selection: From early winter to March of the following year, select robust and disease-free kapok seedlings with a diameter of 2 to 3 cm at breast height and at least one round of branches with a diameter at breast height of 2 to 3 cm from early winter to March of the following year. figure 1 Shown);

[0032] 2) The choice of scion: select two-year-old ceiba tree from the flowering ceiba mother tree, which is strong and full of buds with the same thickness as the rootstock. The scion length is 4~5cm (such as figure 2 Shown);

[0033] 3) Grafting: All branches of the rootstock in the first round of different directions are grafted by the incline cutting method. The specific operation is: at the lower end of the full bud of the scion 0.16~0.26cm, cut the length with or without xylem. The bevel is 2.1~3cm, and the inclination angle is 30°~45°; the requirement for the rootstoc...

Abstract

The invention discloses a grafting method correcting crown deflection of bombax ceiba grafted seedlings. A robust bombax ceiba seedling with one or more rings of branches is selected and used as a stock, and a robust and upright bombax ceiba branch bud which is equivalent to the branches on the stock in thickness is selected and used as scion; the slope cut-grafting method is used for enabling a cambium and phloem of a scion slope to be aligned and connected with cambiums and phloem of slopes of the branches of the stock in a sealed mode, and the joints are bound and fixed through plastic films. The specific slope cut-grafting method is used for carrying out grafting on different branches of the first ring of branches of the stock, the area of grafting operation of the stock is large, survival of grafted seedlings is not affected, and the survival rate of the grafted seedlings can reach 96.67%. Due to the fact that branches in different directions are grafted, balanced and equal growth of all branches is more facilitated, crown deflection is avoided, the grafted seedlings has the better ornamental trait, potential safety hazards are avoided, and the grafting method can be widely applied to gardens and parks.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation and relates to a grafting method for correcting partial crowns of kapok grafted seedlings. Background technique [0002] As the city flower of Guangzhou, kapok (Bombax ceiba) has rich and diverse genetic resources in my country, among which there are some varieties with excellent ornamental properties, such as "yellow flower kapok", "big flower kapok", "multi-flower kapok" and so on. However, excellent germplasm resources are always extremely scarce, and some varieties have even reached the endangered stage. Therefore, protecting resources and multiplying the number is a top priority for scientific researchers. The sowing and propagation of kapok seeds is easy to cause the separation of offspring traits, which is not conducive to the preservation of the genetic traits of the female parent, and the maturity period is long; the cutting propagation of kapok takes a long time, has no taproot...
