Embodiment 1

[0020] Embodiment 1: put the seed into the prepared 0.05% H 2 o 2 Submerge the seeds in the seed soaking solution, soak for 10 hours in an indoor environment, pour out the soaking solution, rinse with clean water repeatedly, and then dry it for sowing. Select a 200-hole black hole tray as the germination bed. Each hole is filled with substrate, and each cell is clearly visible. Use the same hole tray to place it vertically on the tray filled with substrate, and place your hands flat on the hole. Gently press down on the plate, randomly select the plump and healthy seeds to be sown, put the seeds on the plate with well-pressed holes, put 3 seeds in the center of each hole, cover the original substrate after sowing, and use a scraper to remove the seeds from one end of the plate. Scrape to the other end so that the substrate surface is equal to the plate surface. The management of the trays is the same as the general production management. After the trays are placed, each is sp...

Abstract

The invention discloses a method for rapid breeding of winter rape seedlings and improving cold resistance. The method includes the steps of preparation of a seed-soaking reagent; seed soaking with hydrogen peroxide (H2O2), preparation of a seedling bed, seedling of an incubator and transplanting. Through combination of seed-soaking treatment with the low-concentrate H2O2 seed-soaking reagent with plug seedling at indoor temperature, seed breeding period of rape is remarkably shortened, activity of the seeds and cold resistance of the seedlings are favorably improved, and problems about land shortage for the rape due to delay of maturity of previous crops and cold damage in the seedling stage are solved; meanwhile, weak seedlings and lack of seedlings due to bad environment or poor management are made up, cold resistance of subsequent complementary planting of rape seedlings is improved, and overall output is stabilized; the method is simple and reliable and low in cost and can be promoted and applied extensively, time for early seedling of the rape is shortened, and meanwhile, output loss due to cold damage or lack of the seedlings can be saved timely.

Description

technical field [0001] The invention relates to plant cultivation, in particular to a method for breeding winter rapeseed seedlings. Background technique [0002] The middle and lower reaches of the Yangtze River is an important production area of ​​rapeseed in my country, which once accounted for nearly 70% of the total planting area of ​​rapeseed in the country. In recent years, due to the postponement of rice maturity, the land use of rapeseed has become increasingly tense, and the sowing date of rapeseed has also been delayed. Under the environment of global warming, extreme weather is increasing day by day, and cold waves occur more frequently during the growth period of rapeseed, which leads to a sharp drop in rapeseed yield and affects farmers' expectations for rapeseed planting. However, with the rapid development of industry, the world's oil supply has become tense, and my country is also facing the problem of insufficient oil supply. How to solve the current shor...
