Abstract:

Direct seeding is an important rice planting method. It is widely used at home and abroad due to its advantages of saving labor, time and cost and significantly improving the comprehensive benefits of rice planting. In this paper, the research status and progress of direct seeding rice at home and abroad were elaborated, and three main direct seeding rice planting methods, namely wet direct seeding, water direct seeding and dry direct seeding, were introduced. Main problems in direct seeding rice production were analyzed from the aspects of yield, weed control and lodging resistance, and countermeasures were proposed as cultivating suitable varieties, appropriate nitrogen application, lodging resistance, weed control, and integrated development of agronomic practices and agricultural machinery. The paper also discussed the development trend of direct seeding rice, in order to provide reference for the cultivation and promotion of direct seeding rice with high yield and lodging resistance.

Key words: direct seeding rice, lodging, mechanized planting, weed damage
