Method for increasing sprouting rate and seedling rate of directly-seeded early season rice

The invention discloses a method for increasing the sprouting rate and the seedling rate of directly-seeded early season rice. The method includes the steps of soaking directly-seeded early season rice seeds through a compound solution, increasing the sprouting rate and the seedling rate of directly-seeded early season rice through the cooperation with a rice seedling bed management method of directly-seeded rice, airing directly-seeded early season rice seeds in advance, preparing a compound soaking agent mother solution, soaking seeds for 2 days according to the ratio that 1 Kg of seeds are soaked in 1 liter of soaking solution, conducting stirring to evenly soak seeds, conducting heat preservation and germination accelerating for 2-3 days after seeds are taken out, leveling a direct seeding field according to requirements of directly-seeded rice, making drainage ditches according to the requirement that the field face is smooth and no obvious accumulated water or large-area protrusions are generated, and e
