Inverted root-accelerating and cutting seedling culture method

Abstract

The invention discloses an inverted root-accelerating and cutting seedling culture method. The inverted root-accelerating and cutting seedling culture method comprises the steps of land preparation, bedding, film mulching, cutting slip shearing and cutting slip primary treatment, specifically, the lower ends of cutting slips are soaked in a 1000*10<-6 > mg / ml ABT rooting powder first solution for2-3 cm, the cutting slips are taken out after being soaked for 0.5 h, and then inverted rooting acceleration is prepared; root accelerating treatment is carried out on cuttings in an inverted buried sand storage manner, secondary treatment is carried out on the cuttings, secondary treatment is carried out by using a 500*10<-6> mg / ml ABT rooting powder first low-concentration solution, and cuttageis carried out after the treatment; the cuttage time is the last ten days of April, and enough final singling water is irrigated immediately after cuttage; the cuttage density and the plant spacing are 10-15 cm, and finally seedling management is performed. An inverted root-accelerating and cutting seedling culture method is adopted to enable root calluses of the plants to form integrity; the rootaccelerating time is shortened by 5-7 days; manpower and financial resources are saved; under the condition that the soil texture, the environment and the seed branches are the same, the seedling rate of the inverted root accelerating technology is higher than that of a traditional method.

Description

Technical field [0001] The invention relates to an inverted root prompting cutting seedling raising method, which belongs to the technical field of agricultural cultivation. Background technique [0002] At present, the conventional cutting rooting methods of cutting seedlings in production include water soaking method, soil burying method, growth hormone, electric heating rooting, etc. Although the technology is mature, for Qinghai alpine regions, the ground temperature has risen to full, the temperature difference between day and night is large, and cutting seedlings is more difficult. The survival rate is very low. [0003] In the current field, cuttings that have not undergone root stimulating treatment are directly inserted. After germination, the root system has not the ability to absorb water and nutrients, and the germinated shoots cannot grow smoothly. If the water and nutrients of the cuttings are exhausted, the roots cannot supply water and nutrients normally, and the g...

AI Technical Summary

Problems solved by technology

Although the temperature has risen from March to April in spring, due to the large temperature difference between day and night in the alpine area of ​​Qinghai, the ground temperature rises slowly.

When cutting in the open field in spring, due to the high temperature and low soil temperature, the newly germinated shoots often wither due to insufficient water supply, which affects the survival rate of cuttings
