High-quality stock-scion combined grafting reproducing technology for hawthorns

Abstract

The invention relates to a high-quality stock-scion combined grafting reproducing technology for hawthorns. Malus pallasiana is selected as basic stocks, sorb is selected as middle stocks, and crabapple bud-mutation hawthorns are selected as scions. The high-quality stock-scion combined grafting reproducing technology specifically includes the following steps: (1) grafting the hawthorns: sowing the malus pallasiana and the sorb in the early May, starting grafting when the plant heights of seedlings are about 1 m, adopting a scion grafting method, adopting sorb branches, removing the heads of the grafted portions of the malus pallasiana stocks for grafting, and carrying out grafting with a cut-grafting method; (2) carrying out management after grafting: in order to enable grafted seedlings to well grow, strengthening field management work such as fertilizer and water applying, weeding and insect disease prevention during the fast-growing period. By means of the high-quality stock-scion combined grafting reproducing technology, the dual effects of sight enjoying of the hawthorns and eating of haws in autumn and winter are achieved, the eating mode of eating frozen fruits in winter is additionally achieved, the planting benefits are increased, and the effect of landscape trees in the northeast China in winter is achieved.
