Raise seedling with soil and non-soil replanting method for cotton

Abstract

The invention relates to a method for seedling culturing with soil and transplanting without soil of cotton, which belongs to the technical field of cotton breeding. After being fully mixed, cotton seeds and rooting agent are planted into a the groove of a seedbed; two layers of ground film are used to cover the seedbed with the seeds sowed in; cotton seedlings are transplanted without soil aftera leaf and a core to five leaves and a core grow; the cotton seedlings after being transplanted are not restricted by the space in plastic pots for seedling culturing without soil and nutrition troughs for seedling culturing with soil, the volume of the nutrient soil occupied by the roots is large, water and fertilizer are adequate, plus the medicinal effect of nutrient liquid, the cotton seedlings are stronger than those cultured through matrix or nutrition trough seedling culturing method; after transplanting, the rejuvenation period is short, the growth recovery is fast and the survival rate is high. The method solves the problems that the labor required for nutrition trough seedling culturing and transplanting is heavy, the labor intensity is high, the seedbed management is complicated, the roots in seedling culturing without soil and transplanting are easy to be injured and the growth recovery of the roots is slow after transplanting. The method has low labor intensity in seedling culturing and transplanting with the seedbed easy to be managed, can culture seedlings in front of and behind houses, in the field or on the land, and is in particular applicable in household seedling culturing of farmers.

Description

Technical field: [0001] The invention relates to a cotton seedling raising and transplanting method, in particular to a soilless cotton seedling growing and transplanting method. Background technique: [0002] In order to increase the survival rate of cotton seedlings after being transplanted to the field, cotton seedlings are now mainly raised using the technology of nutrient pot seedling cultivation, that is, cotton seeds are sown into nutrient pots to germinate and grow indoors or in greenhouses. After the cotton seedlings grow to a certain extent, Dig ditches or dig holes at certain intervals in the field, then transplant the cotton seedlings and nutrient bowls together with soil into the ditch or caves of the field, and cover the nutrient bowls with soil. Adopting the method of transplanting with soil after raising seedlings in nutrient pots, although the survival rate of cotton seedlings transplanted, cotton yield and quality have been greatly improved, there are also ...

AI Technical Summary

Problems solved by technology

The disadvantage of this technique is that first, the root system is easily damaged when the cotton seedlings are taken out, and the degree of damage to the root system has a great relationship with the survival rate after transplanting, which in turn affects the future yield; Difficult to grasp, less watering affects the survival of cotton seedlings, and the large amount of watering reduces the ground temperature, which is not conducive to the growth of cotton seedlings; third, the fixed cost of raising seedlings in this method is large, and the cost of raising seedlings is high, and farmers cannot raise seedlings one by one
