Problems solved by technology

[0002] At present, American rose rootstocks M1 and M2 perform well in the south of the Yangtze River in my country, and can be directly grafted with rose varieties to cultivate tree-like roses. Although they grow rapidly in the north of the Yangtze River, due to their poor cold resistance and physiological drought resistance, Overwintering in the open air is difficult, it is difficult to popularize and apply, and there is still no solution so far

Embodiment Construction

[0017] 1. Rootstock preparation:

[0018] According to the requirements of different stem heights of rose trees, the 1-year-old stems (2-year-old rootstocks) American M1 and M2 rootstocks are cultivated so that the thickness at the fixed stem height reaches 0.5cm-0.8cm during grafting.

[0019] 2. Scion preparation:

[0020] For the branches of roses that were born in the current year, topping (removing the top buds) is carried out one week before grafting and ear picking to promote the maturation of buds.

[0021] 3. Grafting:

[0022] ① Time: July to August;

[0023] ②Grafted varieties: cold-resistant rose varieties that can withstand low temperatures below -15°C;

[0024] ③Grafting method and operation: "T-shaped" budding or budding with wood inlay. At the fixed dry height of the rootstock, two buds are grafted at opposite positions on both sides of the rootstock, and the exposed buds are tied tightly with a plastic film binding tape. After grafting, apply "Taizhibao" ...

Abstract

The invention discloses a method for cultivating tree-rose semi-finished rose trees through U.S.A. M1 and M2 rootstocks. The method adopts the method of grafting a cold-resistant rose variety onto U.S.A. tree-rose rootstocks, and greatly improves the cold resistance of the rootstocks by utilizing the influence of the grafted variety on the rootstocks, thereby achieving the aim of allowing tree-like rose rootstocks to safely overwinter in open air in northern China. Meanwhile, the method utilizes the characteristic of roses in vigorous growth to accelerate the thickening growth of the cultivated tree-rose rootstocks. Through the cultivation of the rose trees with certain crown-width semi-finished products, the aim of allowing tree-like roses to be shaped early and leave nurseries early is achieved.

Description

technical field [0001] The invention relates to the field of garden plant cultivation, in particular to a method for cultivating semi-finished Chinese rose trees with American M1 and M2 rootstocks. Background technique [0002] At present, American rose rootstocks M1 and M2 perform well in the south of the Yangtze River in my country, and can be directly grafted with rose varieties to cultivate tree-like roses. Although they grow rapidly in the north of the Yangtze River, due to their poor cold resistance and physiological drought resistance, Surviving the winter in the open air is difficult, difficult to popularize and apply, and there is still no solution so far. Contents of the invention [0003] The purpose of the present invention is to provide a solution to the problem of tree-like roses overwintering in the open field in northern my country, so that tree-like roses can grow well in the north, and at the same time solve the problem of accelerated growth of their dry d...
