A kind of cabbage seed production method

Abstract

The invention discloses a seed production technology of cabbage, which adopts the following seed production method: cutting the lateral buds from the nodes, culturing them on the culture medium, and continuously subculturing in the laboratory to obtain the original mother plant; breeding the sterile line: Preparation of sunbeds; preparation of seedling trays; artificial planting of mother plants; maintainer seedlings; planting; pollination; ventilated harvest: remove the row of maintainer plants in the middle of pod formation, increase the row spacing to facilitate ventilation and light transmission, and cut when 70% of the pods turn yellow Make it post-ripening, threshing after drying; male parent breeding: strict bud selection standards, standardized bud peeling and pollination operations, and well-marked pollination; hybrid breeding. The invention provides seed production technology, the yield reaches 65-75kg / mu, the bud rate and bud vigor are as high as more than 85%, and the seed yield is high, laying the foundation for realizing the stable production of cabbage; after planting, whether it is disease resistance, cold resistance Compared with other varieties, it has obvious advantages in terms of physiological shape and output, and is convenient for popularization and planting.

Description

Technical field [0001] The invention belongs to the technical field of vegetable seed production, and particularly relates to a cabbage seed production technology. Background technique [0002] Cabbage, also known as head cabbage, is commonly known as cabbage. It belongs to the cruciferous family and is native to the northern coast of the Mediterranean. It was introduced to China in the 16th century. It is an important vegetable commonly grown throughout my country and occupies an important position in vegetable cultivation and supply. It has strong adaptability, easy cultivation, resistance to transportation, high application value, and a wide range of edibles. It is an indispensable vegetable delicacy on the human table and has become an important cultivated vegetable species in the world. [0003] The world’s planted area is 24.6 million mu, and my country’s cabbage area has reached 12 million mu, accounting for 48.8% of the world’s planted area. Nowadays, it is widely cultivat...

Problems solved by technology

Existing problems: mature flowering season and other production are in the same period as the rainy season and smog. Continuous rain is not conducive to plant flowering and pollen transmission and pollination. In addition, diseases and insect pests will survive the winter and occur in large numbers in early spring, which cannot ensure the robustness of the plants. Especially It is the development of side shoots, causing serious difficulties for breeding

[0007] The invention with the patent application number 201410369272.9 discloses a cultivation method specifically related to increasing the amount of cut flowers and seed production of kale, and discloses a cultivation method for increasing the amount of cut flowers and seed production of kale, including adjusting the sowing date , seedling raising, planting, field management, harvesting cut flowers, stalk treatment, leaf ball treatment, timely pollination, batch harvesting and other treatments, the invention is simple, easy to operate, and the effect is obvious, which can make the cut flower kale can be harvested One fresh cut flower, and the output of fresh cut flower increased by more than 30%, can also significantly increase the seed yield, increase the seed yield by more than 20%, and also improve the quality of the seed, reduce the production cost, and increase the benefit, but the feather coat in the patent Cabbage is generally used as an ornamental, and the methods provided cannot solve the problems of low yield, disease resistance and seed production of head cabbage.

[0008] The invention patent with the application number 94100993.9 discloses the method of hybrid seed production of cabbage, but after planting, the yield is 3300-3800 kg per mu, which is low and difficult to meet the market demand
