Embodiment Construction

[0023] In order to make the objectives and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0024] The embodiment of the present invention provides a red pear dwarfing interstock dense planting cultivation technique, which includes the following steps:

[0025] S1. Cultivation of seedlings: select Zaosu red pear and Wuhong pear as red pear varieties, select Zhong'ai No. 5 as the dwarfing intermediate stock, and use Douli or Duli as the base stock. Sowing Douli or Duli in the first spring in the trench Seeds were grafted on the dwarfed interstock Zhong'ai No. 5 in the early spring of the second year, and cultivated red pears were grafted on the dwarfed interstock in the early spring of the third year. The length of the interstock was...

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.

Description

Technical field [0001] The invention relates to the field of agricultural planting, in particular to a dense planting cultivation technique of a red pear dwarfing interstock.
