Close planting cultivation technology of red pear dwarf interstocks

Abstract

The invention discloses a close planting cultivation technology of red pear dwarf interstocks. Zaosu red pear and Wuhong pear are selected as red pear varieties, Zhongai No.5 is selected as the dwarfinterstocks, pyrus calleryana or pyrus betulaefolia is selected as grafting stock, pyrus calleryana or pyrus betulaefolia seeds are sown in furrows in spring of the first year, the dwarf interstock Zhongai No.5 is grafted on the grafting stock in early spring of the second year, red pears are grafted and cultivated on the dwarf interstocks in early spring of the third year, and the interstocks are27-30 cm long; nursery stocks are transplanted in winter of the third year. The dwarf interstock Zhongai No.5 can weaken growth vigor of branches and promote branching and formation of flower buds, crowns are reduced, and ventilation and light transmission are good; diseases are reduced, disease and pest control is facilitated, and coloring of fruits is facilitated, so that the high yield effectcan be realized.
