A method for promoting roots and raising seedlings of grape hard branches in an electric heating hotbed in the arid area of ​​Northwest China

Abstract

The invention discloses an electric hotbed root-promoting and seedling-raising method for grape hard branches in the northwest arid area. The method comprises the following steps of cutting recovery, cutting storage, electric hotbed arrangement, cutting slip treatment, hotbed heating and management, hotbed powering-off and cooling training, and field cutting seedling-raising. The method has the advantages that through the technical measures of rooting powder soaking, electric hotbed heating root-promoting, field cutting seedling-raising and the like, the problems that cutting seedlings from the grape hard branches can not root easily in the northwest arid area and are low in survival rate are solved, the rooting speed of the grape hard branches is increased, the current-year growing period of the seedlings is prolonged, the seedling quality is greatly improved, the rate of the high-quality strong seedlings reaches 90% or above, and the problems are solved that the survival rate of local grape hard branch cutting is low and the planting survival rate of seedlings delivered from foreign regions is influenced because of water loss. The method lays the foundation for the scale production of grape seedlings and the healthy and rapid development of the grape industry in the area.

Description

technical field [0001] The invention relates to the technical field of asexual reproduction, in particular to a method for promoting roots and raising seedlings of grape hard branches in an electric heating hotbed in the arid area of ​​Northwest China. Background technique [0002] There are many varieties of grapes, which can be divided into fresh eating, drying and wine making in terms of eating methods. Grapes are loved and demanded by people because of their rich nutritional value and effective health care functions. The demand for grapes in domestic and foreign markets is also increasing. increase. The northwestern part of Northwest my country is dry and rainless, with vast and flat land, convenient transportation, rich light and heat resources, large temperature difference between day and night, long sunshine hours, and a long history of sporadic cultivation. It is a priority area for the development of grapes. Most of the cultivated land in the area is sandy loam to ...

AI Technical Summary

Problems solved by technology

Due to poor cold and drought tolerance, grape seedlings are easy to lose water when transported from other places, which will lead to low planting survival rate and poor growth of seedlings; using traditional cutting and layering methods to raise seedlings, first, the seedling production is limited, and second, the survival rate Therefore, it is the key to promote the development of the grape industry to test and research a set of methods that can effectively solve the problems of difficult rooting and low survival rate of grape cuttings in severe cold and dry areas.
