Stock seed propagation method of broccoli

Abstract

The invention belongs to the technical field of broccoli breeding, and particularly discloses a stock seed propagation method of broccoli. The method comprises the following steps: sowing in a seedling raising plate, managing until the broccoli has buds in the seedling raising plate, carrying out land selection, field planting, topdressing and pollination, and then the broccoli grows until seeds are harvested. According to the technical scheme, plant vegetative body can be weak, ball flowers become small and do not need to be cut, diseases and insect pets are controlled, pesticide treatment is convenient, the quantity of flowers after bolting and flowering is uniform, and the seedlings can be quickly transferred to a proper climate for pollination at an extreme temperature.

Description

technical field [0001] The invention belongs to the technical field of pine cauliflower breeding, and in particular relates to a method for breeding the original species of pine cauliflower. Background technique [0002] In recent years, cauliflower with loose curds (referred to as loose cauliflower, the same below) has won the favor of consumers for its tender green pedicel and crisp and sweet quality, and it is rapidly popular in domestic mass cities. , Songhua cauliflower has loose bulbs, long and green pedicels, and tastes sweet, crisp and tender. When frying and cooking, it is not easy to rot, and the color of the pedicel becomes greener after heating, and the appearance is good; when dehydrating, the edible pedicels are mainly long and green. According to the analysis of the main nutritional quality of Songhuacai, the chlorophyll content is 12.8μg·g -1 (FW), carotenoid content 3.3μg g -1 (FW), VC content 629mg·kg -1 The soluble sugar content is 2.82%. Compared with...

AI Technical Summary

Problems solved by technology

However, pine cauliflower varieties generally have large vegetative bodies, and the development of the plant type leads to a large row spacing during the production of the original species, which leads to a waste of land. Diseases and insect pests such as diamondback moth and aphid outbreaks; when the curds of pine cauliflower mature, the curds are larger, cutting the bulbs is not only a waste of photos, but the wounds caused by cutting the bulbs are often infected, resulting in sclerotinia, soft rot and other diseases; self-incompatible lines Uneven ball cutting of pine cauliflower varieties leads to more flowers after bolting and more concentrated flowering, and the artificial pollination speed cannot keep up, resulting in many flower buds being unable to pollinate successfully; mid-to-late maturing varieties of pine cauliflower have a late flowering time and encounter high temperatures in the later stage Climate pollen loses vigor and cannot set seeds normally, leading to crop failure
