Embodiment Construction

[0014] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] The embodiment of the present invention provides a method for inducing bolting and flowering of head cabbage by grafting under artificial climate conditions, comprising the following steps:

[0016] S1. Selection of scion and rootstock: choose the stem tip of cabbage G27 as the scion; Chinese cabbage is very easy to bolt, and it is easy to divide the side shoots, and the rootstock can be both the main shoot and the side shoots of 49 Chinese cabbage, but considering the nutrition For the problem of supply and light competition, choose at most 3 main shoots or side shoots of Chinese cabbage as rootstocks; choose 49 Chinese cabbage as rootst...

Abstract

The invention discloses a method for inducing bolting and flowering of common head cabbages by grafting under artificial climate conditions. The method includes the steps: firstly, selecting proper scions and stocks; creating strong-illumination and long-day total environments with proper temperature difference after grafting; performing proper management after scion common head cabbage stem tipsspend a seedling recovery period; finally, artificially pollinating the scion common head cabbages. The stem tips of the common head cabbages G27 serve as the scions, 49 Chinese flowering cabbages easily bolting serve as the stocks, the common head cabbage stem tips are grafted on rachises of the Chinese flowering cabbages, operation is more convenient, pollution can be decreased, and grafting survival rate is increased. In addition, the 49 Chinese flowering cabbages easily form side mosses, and more stock sources can be provided for grafting. After grafting, strong radiation treatment is performed, the stem tips can be promoted to form chlorophyll, and growth of the scions can be accelerated. Induction of bolting and flowering of the scion common head cabbages can be accelerated by long-day treatment. According to the method, the scion common head cabbages can be promoted to form inflorescence 26 days after grafting at the soonest.

Description

technical field [0001] The invention relates to the technical field of vegetable grafting, in particular to a method for inducing bolting and flowering of cabbage by grafting under artificial climate conditions. Background technique [0002] Heading cabbage, also known as cabbage, cabbage, cabbage, etc., is a variety of Brassicaceae and Brassica cabbage species. It is widely cultivated in various parts of our country and is one of the main vegetables in our country. In order to improve the disease resistance of cabbage varieties, increase yield, improve quality, etc., the core work of breeding experts is to breed new varieties of cabbage with excellent agronomic traits. At present, hybrid breeding is still an important method for cultivating and improving new varieties of cabbage. Because cabbage vegetables are typical green body vernalization plants, unlike cabbage vegetables that can feel low temperature during the seed germination stage, head cabbage can only feel low te...
