Zusammenfassung:The invention discloses a method for improving the direct-seeding seedling rate of paddy rice. The method comprises the following steps of before the paddy rice direct seeding is executed, performing seed soaking treatment through gibberellin and fulvic acid: adding 100 kilograms of water, 0.5-1.5 grams of gibberellin and 18-22 grams of fulvic acid into every 50-60 kilograms of paddy rice, performing seed soaking for 72-96 hours, and directly sowing paddy rice seeds which are cleaned or not cleaned after the seed soaking is finished. The method disclosed by the invention is easy and convenient to operate; the direct seeding seedling rate can be effectively increased, and the seedling robustness is promoted; a comparison test of an inventor shoes that the seedling rate can be increased by 20-25 percent, so that the seeds can be saved, and the yield can be increased by over 10 percent.
