Dry direct seeding cultivation method for rice

The invention belongs to the technical field of crop cultivation, and particularly relates to a dry direct seeding cultivation method for rice. The method comprises the following steps: (1) soil preparation; (2) seed selection and treatment; (3) sowing; (4) fertilizing; (5) water management; (6) weeds and pest management; and (7) harvest. According to the cultivation method, rice seeds are sown ona seedbed at depth of 0.5-2 cm after land preparation, the wet no-water layer is kept in the field before the tillering stage, so that the method is more water-saving than the traditional cultivationmethod. Meanwhile, the rice seeds are evenly sown and covered with soil, irrigation is not performed on the field at the early stage, and drainage is performed in advance at the later stage, so thatthe rice seeds can take root and germinate in an oxygen-rich environment, the emergence rate and uniformity of rice seeds can be effectively increased, the lodging resistance and yield at the later stage are increased, and mech
