Problems solved by technology

[0003] Catalpa is a cross-pollinated plant, which itself cannot bear fruit or rarely bears fruit. Lack of seeds and roots have become the limiting factors in the propagation methods of catalpa by sowing seedlings and burying seedlings, which restricts the development of catalpa
However, using common cutting methods, the survival rate of seedlings is low, only 20% to 30%.
In recent years, some places have adopted catalpa rootstock grafting seedling raising method, which has improved the reproduction coefficient of catalpa seedlings, has high reproduction survival rate and fast reproduction speed, but there are also certain disadvantages at the same time, such as the inconsistency between stem grafting and rootstock growth in the later stage ...

Embodiment Construction

[0011] The following is the best embodiment of the method for asexual rapid propagation of catalpa green branch cuttings of the present invention. The operating procedure of the vegetative rapid propagation of catalpa green branch cuttings is as follows:

[0012] (1) Sprout preparation stage: The sprout preparation stage includes seedling root treatment, site preparation and furrowing, seedling laying and post-laying management procedures.

[0013] 1. Treatment of roots

[0014] From the end of October to mid-November, when the catalpa saplings enter the dormant period, they will start to take seedlings from the nursery, cut them off at a distance of 15-20 cm from the ground, cultivate the roots tightly with soil, collect the upper part, and store them as false plants. Unearth after the dormant period and put them in clear water Soak in water, soak up enough water and drain it for later use.

[0015] 2. Soil preparation and furrowing

[0016] Started in mid-December. In th...

Abstract

The invention discloses a Chinese catalpa tree fast asexual propagation method by branch cottage comprising a bud sprout preparation stage, a root speeding stage, a management stage and a transplanting stage after cottage, wherein the bud sprout preparation stage includes seed strip and seed root handling, soil working, seed strip laying and management process, the root speeding stage includes a nursery sock growing bed preparation and bud collection cottage procedure. The invention realizes fast growth rate and high survival rate.

Description

technical field [0001] The invention relates to a cutting propagation method of catalpa, in particular to a method for rapid asexual propagation of catalpa green branch cuttings. Background technique [0002] Catalpa is a multifunctional tree species integrating high-quality timber, garden ornamental, and good ecological protection. It is currently one of the most valuable tree species for development. However, due to its slow growth and difficulty in reproduction, few people plant it. Due to the wide range of uses of catalpa, it is difficult to reproduce, so it has formed a situation of only picking sterility, which makes catalpa, an excellent tree species, face the situation of extinction. In recent years, my country's forestry scientific and technological workers have studied and adopted the method of selecting excellent trees, selected 3 excellent clones of catalpa, and defined 4 types of production. Among them, a set of sowing seedlings has been explored for fast-growi...
