Embodiment 1
[0025] Take 100g of rape seeds with full grains and similar size, put them in 0.05% H 2 o 2 Soak in the solution at about 25°C for 8 hours, then wash with water. Let it dry in a cool place for 3 days, then store it in a sealed bag for later use. The treated seeds were sown by conventional methods.
Embodiment 2
[0027] Take 150g of rape seeds with full grains and similar size, put them in 0.05% H 2 o 2 Soak in the solution at about 15°C for 12 hours, then wash with water. Let it dry in a cool place for 4 days, and then store it in a sealed bag for later use. The treated seeds were sown by conventional methods.

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...
