Method for treating seeds for promoting germination of oilseed rape and improving cold resistance of oilseed rape

Abstract

The invention discloses a method for treating seeds for promoting germination of oilseed rape and improving the cold resistance of the oilseed rape. The method is characterized by comprising steps of 1), preparing the seeds, to be more specific, preparing the oilseed rape seeds to be sown during production and conventionally screening the seeds for standby application; 2), treating the selected oilseed rape seeds by the aid of chemical agents, to be more specific, soaking the selected oilseed rape seeds in 0.05% H2O2 solution at the room temperature of 20-25 DEG C for 4-8h or at the room temperature of 10-15 DEG C for 8-12h, and then repeatedly washing the oilseed rape seeds by the aid of tap water; 3), dehydrating and drying the seeds, to be more specific, spreading and drying the treated seeds in shade places under a room-temperature condition for 1-5 days, and storing the seeds in sealed bags for standby application after the water contents of the seeds are reduced and reach the water contents of the seeds in pretreatment states. The method has the advantages that as proved by tests, germination rates and germination indexes of the oilseed rape seeds treated by the aid of the method are higher than germination rates and germination indexes of untreated control group, and the oilseed rape is high in growth speed after the seeds are germinated and can grow robustly.

Description

technical field [0001] The present invention uses H 2 o 2 The invention relates to a solution soaking seed back-drying treatment method, specifically a seed treatment method for promoting the germination of rapeseed and improving the cold resistance of rapeseed, which can promote the germination and growth of rapeseed at low temperature, and belongs to the fields of crop science and seed science. Background technique [0002] Rapeseed is an important oilseed crop in China, and the Yangtze River Basin is an important rapeseed producing area in China and even in the world. Traditional rapeseed production is mainly based on seedling cultivation and transplanting, which requires a lot of labor, high cost and low income. Due to its labor-saving and cost-saving, live rapeseed has developed and promoted rapidly in the Yangtze River Basin. However, the former crops in this area are dominated by japonica rice with a longer growth period, which makes the subsequent rapeseed sow lat...

Problems solved by technology

[0004] Purpose of the invention: the purpose of this invention is to provide a seed treatment method that promotes the germination of rapeseed and improves the cold resistance of rapeseed, improves the germination potential and germination rate of direct seeding rapeseed, and forms early seedlings, uniform seedlings and strong seedlings, so as to solve the problem of producing direct seeding rapeseed. Especially the problems of low seed germination rate, slow seedling emergence and irregular seedling emergence of late-sown rapeseed at low temperature
