A method for improving the survival rate of radish side branch rooting and the quality of seed propagation

Abstract

The invention discloses a method for improving the lateral branch rooting survival rate and the seed reproduction quality of radish. The method comprises the following steps: a second-stage lateral branch is taken as a cutting branch, after the cut-off lateral branch heals naturally, the cut-off lateral branch is soaked in an indolebutyric acid solution for 10 seconds and then inserted in a seedbed substrate composed of coco coir, vermiculite and mushroom dreg; a mixed solution containing Huabao No.1, Huabao No.2 and naphthylacetic acid is sprayed on the branch so that the branch can be acclimated and then survives; when new leaves come out, transplanting is performed by use of an underground simple culture tank filled with planting soil which is composed of coco coir, vermiculite, mushroom dreg and decomposed cow dung; after the cutting lateral branch survives, ventilation and light illumination are realized, Huabao No.1 and Huabao No.2 are sprayed, and after seeds are mature, the seeds are harvested. The method for improving the lateral branch rooting survival rate and the seed reproduction quality of the radish has the advantages that the method of rooting by use of the second-stage cutting lateral branch of the radish is adopted, a new method is provided for solving the problem of seed reproduction material loss of the radish due to the infringement of soft rot, the plants cultured by use of the method are well developed in root system, high in transplanting survival rate, and stable in heritability, and furthermore, the seed reproduction can be saved.

Description

technical field [0001] The invention belongs to the technical field of plant cutting rooting and seed propagation, and in particular relates to a method for high-quality rooting and seed propagation of radish side branch cuttings. Background technique [0002] Radish (Raphanus sativus L.), also known as radish, is one of the popular vegetables with a long history of cultivation in my country, and has a cultivation history of more than 2700 years. Radish is not only a vegetable, but also has certain curative effects on more than 30 diseases of the human body, so it is deeply loved by everyone. At present, the planting area of ​​radish is continuously expanding, and the output is also gradually increasing, and there are more and more researches on radish. [0003] Radish is native to the temperate zone and is a semi-cold-resistant biennial plant. Its vegetative growth and reproductive growth span two natural years, and the growth cycle is long, which leads to the increase of ...

AI Technical Summary

Problems solved by technology

Usually during the reproductive growth period of radish, the onset of soft rot disease is relatively late, and the external symptoms are not obvious. Many materials cannot be harvested for seeds due to untimely control. If effective measures are not taken, materials will be lost.

The method of cutting side branches of radish can solve the problem of germplasm loss caused by soft rot in the process of radish seed retention, but the side branches of cut radish have no main root, only side roots, and the root layer is shallow, so there is a problem that it is not easy to survive
