Cuttage reproducing method for cotton

Abstract

The invention discloses a cuttage breeding method of cotton, which comprises the following steps: 1) grafting cotton bough in the culture medium of regenerated plant to breed root; or soaking cotton bough in the root-growing agent for 20-28h; plugging cotton in the soil-less base; 2) transplanting after the cotton bough grows root.

Description

technical field [0001] The invention relates to a rapid propagation and cultivation method of plants, in particular to a cutting propagation method of cotton. Background technique [0002] Nutrient bowl seedling transplanting technology is one of the main technologies used in cotton production in my country. It is widely used in the cotton production areas of the Yangtze River Basin and the Yellow River Basin on the Huaibei Plain. The annual transplanting area accounts for about 50% of the national cotton planting area, with an area of ​​about It is 45 million mu. But this technology has following serious shortcoming: the one, owing to adopting soil substrate to carry seedling, the needed seedbed area is big, and the ratio of the seedbed area of ​​production and transplanting field area is about 1: 10-12, and seedling also can only adopt one family. It is carried out in a decentralized manner by one household; the second is that due to the heavy weight of the soil matrix car...

Problems solved by technology

But this technology has following serious shortcoming: the one, owing to adopting soil substrate to carry seedling, the needed seedbed area is big, and the ratio of the seedbed area of ​​production and transplanting field area is about 1: 10-12, and seedling also can only adopt one family. It is carried out in a decentralized manner by one household; the second is that due to the heavy weight of the soil matrix carrier during transplanting, the seedlings are easy to disperse in the pot, and the handling and transplanting are labor-intensive and time-consuming, and the transplanting cannot be carried out by mechanization, so the production efficiency is low; the third is Soil substrate transplanted cotton takes root slowly, and the slow seedling period is long, which will also have adverse effects on early cotton

This system is currently the most advanced cotton factory seedling raising system, but it needs a special seedling raising substrate and cotton seeds, so it has not yet reached the goal of cotton seedling raising using only the culture medium and branch cutting technology
