Method for cutting twig of catalpa bungei

Abstract

The invention discloses a method for cutting a twig of catalpa bungei. The method comprises the following steps: selecting the twig, preparing a soak solution, preparing a matrix, selecting a cutting period, treating a cutting pool, and carrying out management after cutting. The rooting rate and survival rate of a tender sprout, cut by adopting the method disclosed by the invention, of the catalpa bungei are high, the seedling emergence time is short, the growth vigor in a later period is good, and economic benefits of growers are greatly improved.

Description

technical field [0001] The invention relates to the field of forest tree breeding, in particular to a method for cutting twigs of catalpa. Background technique [0002] There have always been many difficulties in raising seedlings of catalpa, but there are few studies on provenance test, variety selection, seedling technology, cultivation management mode, etc., and there is no good effect in improving the survival rate of cutting seedlings, making catalpa afforestation. There are almost no sources, and large-scale promotion is greatly restricted. It is very important to study the seedling raising technology of catalpa and improve the survival rate of its seedling raising. In terms of propagation methods, due to the incompatibility of catalpa to its own flowers, the fruit is scarce, and the seed propagation is difficult, and the grafting propagation is prone to disadvantages such as incompatibility and premature aging. The current excellent varieties mainly rely on grafting...

AI Technical Summary

Problems solved by technology

In terms of propagation methods, due to the incompatibility of catalpa to its own flowers, the fruit is scarce, and it is difficult to reproduce by seedlings. Grafting and propagation are prone to disadvantages such as incompatibility and premature aging.

The current fine varieties mainly rely on grafting and propagation. However, rootstocks need to be cultivated for grafting seedlings, and the seedling cycle is prolonged. At the same time, grafted seedlings are prone to graft incompatibility, which affects the later growth of seedlings. The backward propagation technology has become a technical bottleneck that limits the promotion of Catalpa.
