Abstract:

Direct seeding is the common way of rice cultivation at present, it has the characteristics of labor saving, effort saving and high efficiency, and is advantageous to mechanization operation. In recent years, direct seeding rice has developed rapidly in various parts of China. North China is the main production area of japonica rice in China in recent years. The key techniques of direct seeding rice planting in wheat stubble in this area play an important role in promoting the development of high and stable yield of rice. Based on this, the paper expounds systematically the key techniques of direct seeding rice in this area from the aspects of variety selection, direct seeding methods and field cultivation management, in order to provide theoretical guidance for high yield, high efficiency and safe production of rice in North China.

Key words: rice, direct seeding, North China, cultivation model
