Grape multi-resistance rootstock hard branch grafting nutrition bag seedling raising method in arid desert areas

Abstract

The invention provides a grape multi-resistance rootstock hard branch grafting nutrition bag seedling raising method in arid desert areas. The grape multi-resistance rootstock hard branch grafting nutrition bag seedling raising method in the arid desert areas adopts rootstocks which are selected from 5BB and / or S 04, and adopts following steps of gathering of scions, selection of rootstocks, pavement of double layers of electric heating hotbeds, grafting of the rootstocks and the scions, placement of cuttages on the electric heating hotbeds, placement of the cuttages in nutrition bags, and management after cutting of the rootstocks. A plurality of selection tests of rootstock varieties come to a discovery that after rootstocks S04 and rootstocks 5BB are grafted with local cladus, nursery stocks are good in resistances, low in infection rate of diseases and insect pests, strong in saline-alkaline resistance, high in survival rate, and rather good in local adaptability. Greenhouses are further used for carrying out large-scale fast breeding of grape hard branch grafting seedlings, breeding stage is short, and grafting, breeding and planting of the seedlings can be achieved in the same year. The grape multi-resistance rootstock hard branch grafting nutrition bag seedling raising method in the arid desert areas is particularly suitable for arid and saline-alkaline desertification areas, simple and practical in technology, and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of grape seedling cultivation, and relates to a method for cultivating grape seedlings with multi-resistant rootstock hard branches grafted with nutritional bags in arid sandy areas. Background technique [0002] In the arid and desertified areas in Northwest my country, such as Minqin, Gansu, the climate is dry and rainless, the wind and sand are relatively large, and the land salinization is high. , has natural pollution-free production conditions, and the planting of economic trees such as grapes has developed rapidly in recent years. However, in the process of growing grape seedlings in this area, most of the seedlings were imported from other places before, and the seedlings had poor adaptability to the local area at the initial stage, and the survival rate was not high; for local seedling cultivation, grape branches from the local nursery were directly used for electric heating hotbed to promote rooting...

AI Technical Summary

Problems solved by technology

However, in the process of growing grape seedlings in this area, most of the seedlings were imported from other places before, and the seedlings had poor adaptability to the local area at the initial stage, and the survival rate was not high; for local seedling cultivation, grape branches from the local nursery were directly used for electric heating hotbed to promote rooting and cutting seedlings. After the seedlings were transplanted to the nursery field, due to the windy spring in this area and the high salinity of the soil, the seedlings showed dead leaves about 10 days after transplanting, which indicated that the local seedlings had poor resistance and that bare-root seedlings were not conducive to survival.

Therefore it can be said that there is a lack of a grape grafting and seedling raising method that is particularly suitable for arid sandy areas and has excellent seedling resistance and fast breeding speed.
