The invention provides a full set of dry-finishing direct-sowing rice cultivating technologies which can save labor, increase output, resist fall-down and improve soil and the land farming mud layer. As the dry-cultivation and the dry-finishing are adopted, the soil has good crumb structure, good hydroscopic property and good water permeability, which facilitates to ensure that the seedlings can tiller earlier and more at lower positions and the basic seedlings are sufficient; a high-yield seedling rack can be formed easily without transplanting and seedling mitigating and the mature period can be advanced for 7-10 days. By adopting the technology, the requirement of the rice for water in the middle and last period is looser, the maturing rate is high, the kernel is heavy and big and the land farming mud layer can be kept in an optimum state for ever.
