Tunnel half-shading green branch cottage and propagation method of large reed-leaf cherries and Teng county red cherries

Abstract

The invention relates to a tunnel half-shading green branch cuttage and propagation method of large reed-leaf cherries and Teng county red cherries, comprising the following steps: making a cuttage bed by using sandy loam as a ground substance ; making a tunnel by using an agricultural film, thin bamboo poles or mocks; covering the film of the tunnel by using a sun-shading net for shading; selecting cherries in winter and spring-heated greenhouses as cutting seed trees, wherein one cutting wood is three nodes having four buds about 10 to 15 cm in general, the distance from apical buds to pruning wounds is from 0.5 to 1cm, 1 / 2 to 1 / 3 of leaves are reserved on a top leaf, and the roots are cut into a shape of a horse ear; putting the cutting wood into a 800-time carbendazol solution for sterilization and moisture preservation after being cut; watering the slotter by using the carbendazol solution for primary soil sterilization and then punching holes by using small bamboo sticks when in cuttage; fully watering by using the carbendazol solution after cuttage, wherein the humidity in the tunnel is kept more than 85%; hardening off seedlings when finding the growth of new leaves in 26th day after cuttage and then uncovering the film for removing the tunnel after a week; shifting to the normal nursery management after uncovering the tunnel, i.e. weeding, watering, fertilizing, preventing and curing plant diseases and insect pests and the like. The invention has the advantages of high nursery stock breeding rate, high transplanting survival rate, no crown gall, vigorous growth, early fruiting, easy fertility and easy popularization.

Description

technical field [0001] The invention relates to the technical field of asexual propagation of Chinese cherries, in particular to a cutting propagation method of Dawulu (also known as Dawolou, Lou, Lou) leaf cherry and Tengxian Dahong cherry arch shed with semi-shade green branches. Background technique [0002] Chinese cherry [Cerasus pseudocerasus (Lindl) G.Don] is native to my country, with rich varieties and types and strong adaptability. Dawuluye cherry, produced in Zaozhuang, Shandong (see "Chinese Pomology" Chinese Academy of Agricultural Sciences and other editors, Agricultural Press, 1987 edition), the fruit is relatively large, round or nearly round, and the average single fruit weighs more than 2 grams. The peel is thick, purplish red and shiny. The pulp is slightly yellow, dense and soft, sweet and slightly sour, with aroma, more juice, and high quality. It matures in early and mid-May, with the same maturity period, and is more resistant to storage and transpor...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem of high-quality seedlings needed for large-scale development of cherries, overcome the shortcomings of seedling seedlings of poor quality, layering, and slow propagation of ramets, and provide a technology for growing seedlings by green branch cuttings that use shed film to keep warm and keep moisture and semi-shade, and Disinfect the cuttings and soil, and have fast propagation speed, high survival rate, large seedling growth per unit area, and low cost.
