Brassica oleracea seed production technology

Abstract

The invention discloses a brassica oleracea seed production technology, an adopted seed production method comprises the steps that a lateral bud is cut from a knot position and cultured on a culture medium, and subculture is performed in a lab continuously to obtain an original mother plant; seed reproduction of a sterile line is performed; a sun bed is prepared; a seeding tray is prepared; provisonal planting of the mother plant is performed; maintainer line seedling growing is performed; field planting is performed; pollination is performed; ventilation harvesting is performed; in the podding mid-term, maintainer line rows are removed; the row space is increased to facilitate ventilation and light transmitting, 70% of pods are cut when yellowing and dried for threshing after ripening; male parent seed reproduction is performed; the bud selection standard is strictly required, the bud stripping and pollination operation is standardized, and pollination marks are made; coeno-species seed reproduction is performed. According to the seed production technology, the yield can reach 65-75 kg / mu, the germination rate and the germination potential can reach up to 85% or above, the seed yield is high, and a foundation is laid for brassica oleracea stable production; after planting, the species has remarkable advantages over the other species on whether the disease resistance, the cold resistance, the physical shape or the yield, and the brassica oleracea is convenient to popularize, promote and plant.

Description

technical field [0001] The invention belongs to the technical field of vegetable seed production, and in particular relates to a cabbage seed production technology. Background technique [0002] Cabbage, also known as head cabbage, commonly known as cabbage, belongs to the cruciferous family. It is native to the northern shore of the Mediterranean Sea and was introduced to China in the 16th century. It has strong adaptability, easy cultivation, resistance to transportation, high application value, and wide edible range. It is an indispensable vegetable delicacy on the human table and has become an important cultivated vegetable species in the world. [0003] The planting area of ​​the world is 24.6 million mu, and the area of ​​head cabbage in my country has reached 12 million mu, accounting for 48.8% of the world's planting area. Now it is widely cultivated in various parts of our country, and it is one of the main vegetables in spring, summer and autumn in Northeast, Nort...

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
