Embodiment 1

[0013] The Yutong No. 1 material was selected, and the mode of "IBA, NBA (2:1) 1000ppm quick dipping + sand + flat buried new branches + middle part" was adopted, and the rooting rate was 92.57%.

Embodiment 2

[0015] The Yutong No. 1 material was selected, and the mode of "IBA, NBA (2:1) 1500ppm quick dipping + perlite + flat buried trunk new branches + middle part" was adopted, and the rooting rate was 93.00%.

Embodiment 3

[0017] The Yutong No. 1 material was selected, and the mode of "IBA, NBA (2:1) 500ppm quick dipping + vermiculite substrate + flat buried dry shoots + middle part" was adopted, and the rooting rate was 95.34%.

Abstract

A cultivation model of Catalp asexual propagation uses a model which includes two steps: first, makes Catalp asexual stem quick dipping in a solution of IBA, NBA (2:1) 500-1500ppm; second, Catalp asexual stem which is dipped in the solution is levelly buried in the middle to grow in a soil substrate containing vermiculite, perlite and sand. The cultivation model has a plurality of advantages: the cultivation model is simple and easy to learn for forestry and agriculture; degradation phenomenon of good characters for seeds propagation is avoided by propagating Catalp chozen clones using the cultivation model; Catalp seedlings can be propagated massively and quickly; moreover, the average survival rate reaches to more than 95%, and the average survival rate of conventional cuttage method is between 10% and 20%; the raw material used is cheap and easy to be get; the method is simple and practicable. The invention provides a new model for Catalp chozen clones widespreading and seeding fast-obtaining in the process of fast-growing plantation in our country.

Description

Technical field: [0001] The invention relates to a cultivation method for seedling asexual reproduction, in particular to a cultivation mode for catalpa asexual reproduction. technical background: [0002] Catalpa bungei C.A. Mey. belongs to the Bignoniaceae family and belongs to the genus Catalpa. It is a precious high-quality timber tree species and a famous garden ornamental tree species in China. Catalpa is different from other tree species in that its material is hard and known as the "King of Wood". It has high content of tannin, phenol and other substances in its body. Therefore, Catalpa is a tree species that is difficult to root, and the survival rate of cuttings is not high. Conventional cutting cuttings are difficult to root, the grafting survival rate is unstable, the cycle is long, and the cost of test-tube seedlings is high. Therefore, the difficulty of vegetative reproduction of catalpa has become a prominent problem. Scientists have also carried out a lot o...
