Embodiment Construction

[0004] The present invention uses hydrogen peroxide for seed dressing, which utilizes the strong oxidizing property of hydrogen peroxide to enhance the permeability of wheat seed coats, and has a killing effect on germs on the surface of seed coats, and the use concentration is 0.2-5%, which is optimized to 1%. After planting for 1 hour, rinse with clean water to remove the inhibitors on the seeds that are unfavorable to seed germination; gibberellin 1-20PPm, optimized to 5ppm; ethephon 1-20ppm, optimized to 10ppm; potassium dihydrogen phosphate 50- 500ppm, optimized to 200ppm. The solution is sprayed to make the water holding capacity of the seeds reach 40% of the seed quality, and kept at 15-20° C. for 2-3 days to promote the transformation of nutrients and hormone components in the seeds, and then dried and ready for sowing.

Abstract

The invention discloses a method for improving the cold resistance of late-sowed wheat. The method is particularly suitable for planting wheat which cannot be sowed on time because of wet-stained soil or low soil moisture content. The method comprises the following steps of: mixing seeds with hydrogen peroxide; flushing and spraying the seeds with clean water; flushing and spraying the seeds with solutions of gibberellin, ethephon and monopotassium phosphate for multiple times; after flushing and spraying, placing the seeds at a warm place to convert internal nutrition and hormone of the wheat seeds; when one or more seeds root, spreading and airing the seeds; and before sowing the seeds, mixing the seeds with a rare earth tiny fertilizer to promote the growth and improve the cold resistance at a wheat seedling stage. The wheat seeds treated by the method have the advantages that: the germination speed is high; the root system is developed; the tillering ability is enhanced; the cold resistance of wheat can be obviously improved; the late-sowed wheat can safety live through the winter; and the yield of the wheat can be obviously improved.

Description

technical field [0001] The invention relates to a method for promoting germination and cold resistance of wheat, in particular for safe overwintering of late-sowed wheat caused by soil wetness or poor moisture content. technical background [0002] Wheat is the main food crop in northern my country. The sowing period is generally from late September to early October, and harvested in early June of the following year. The sowing date of wheat is greatly affected by the weather. When there is a lot of rain, the farmland is wet. Sometimes the weather is severe and the soil is too dry to sow seeds in time, which often delays the sowing date. After the delayed sowing date, the germination and growth of wheat are affected due to low temperature , often fail to reach the overwintering index, so that the seedlings will drop significantly in winter, which seriously affects the wheat yield. Contents of the invention [0003] The purpose of the present invention is to provide a met...
