Cutting Propagation Technology of Cotton Nodes

Abstract

The invention relates to the technical field of asexual reproduction of crops, in particular to a method for rapidly multiplying seeds by cutting cotton nodes. During the cotton growth and development season, the main stem node or fruiting branch node of the cotton plant is used to cut cuttings with a length of 5 to 8 cm, and one node and one leaf are used for cutting; The soil is disinfected, and the water content is subject to the saturation of the soil surface. Cover the top of the cuttings with an arch film, and seal them with soil around them to maintain temperature and humidity. After 20 days, it can be transplanted to the field. Field cultivation is the same as conventional cultivation. The cutting seedlings cultivated by this method have a transplanting seedling rate of about 98%, which can save costs.

Description

technical field

[0001] The invention belongs to the technical field of asexual propagation of crops, and in particular relates to a method for quickly propagating seeds by cutting cotton nodes. Background technique

[0002] At present, the reproduction of cotton is sexual reproduction, that is, the use of seeds for reproduction. If the cotton node cutting propagation technology is applied to cotton scientific research and production, one can avoid the separation of traits in sexual reproduction and rapidly expand the quality of cotton. The population can provide good parents for the utilization of excellent traits; the second is to speed up the propagation of special germplasm resources, such as the high-quality mutant strains or wild cotton found, often have no seeds or few seeds, at this time, node cuttings are used for propagation , can quickly increase seed production; third, it is used for heterosis fixation, and cutting propagation can maintain all the excellent traits...
