Propagating method for ceiba insignis

Abstract

The invention relates to a propagating method for ceiba insignis and belongs to the technical field of tree grafting. The method specifically comprises the following steps: (1) selecting a tree stock: cultivating ceiba pentandra as the tree stock; (2) cultivating and selecting bud shoots: selecting a single plant colony with excellent features as a propagating garden for bud-shoot spike picking, and cultivating straight branch bud shoots with sufficient trunks in present year according to the grafting requirement, wherein the size of the bud shoots is consistent to or slightly less than the size of the grafting ports of the tree stock; (3) grafting: adopting a stem grafting method as a grafting method; (4) managing growth: removing tree stock buds in time, thereby guaranteeing the normal growth of the grafting seedlings, and meanwhile, adopting a general nursery garden management method for performing other water and fertilizer management; and (5) supplementary grafting: re-grafting after buds grow on the tree stock and grow to the size of common tree stock if few grafted plants fail to survive. After the method is adopted, the joint of the grafted plant can effectively heal, the grafting survival rate is high, the growth is fast, the happening of bleeding diseases is reduced, the grown plants have few prickles, the tree shape is symmetrical, and the blooming is relatively regular and uniform.

Description

technical field [0001] The invention relates to a propagation method of different kapoks, in particular to a breeding method of beautiful kapoks with high survival rate, fast growth and high ornamental value, and belongs to the technical field of tree grafting. Background technique [0002] In the 1990s, a large number of beautiful different kapoks were introduced, and the method of sowing and propagation was generally adopted. It should be harvested and sowed at the same time, and the germination rate could reach 90%. The trunk has many and large thorns; the general flowering time is from November to December every year, but after the introduction and planting, it starts to bloom one after another from June to July every year (premature aging phenomenon), which is not consistent, and the amount of flowers varies greatly. large, with severe degradation. [0003] Later, with the efforts of some merchants in the Pearl River Delta, some plants with good tree shape, few prickle...

Problems solved by technology

[0007] Rootstock selection: In the early stage of the introduction of the beautiful kapok in the 1970s, due to the beautiful flowering of this tree species but its scarcity and difficulty in reproduction, relevant scientific and technical personnel used ordinary kapok trees as rootstocks for grafting, but the effect was not good. The affinity is not strong, and the survival rate of grafting is not high; secondly, due to the fast growth rate of the beautiful kapok and the slow growth of the kapok tree, the limited surviving plants also show top-heavy and capped, severe growth failure
