Abstract
[Objective]To find out a best sowing mode of dry-land wheat under the condition of mechanical seeding condition.[Method]The four sowing modes were adopted,including conventional drilling(CK),broad-row mix sowing,seedling belt sowing and no-tillage furrow see-ding.Effects of different sowing modes on the soil moisture before sowing at different soil depths,emergence quality of wheat seedlings,wheat growth at wintering stage, wheat yield and its component factors, production cost and planting return were studied.[Result]Conventional drilling had the highest yield, while no-tillage furrow seeding saved labor, had high yield, good earnings and complete seedling emergence. [Conclusion]This research provided technical support for promoting the integration between agricultural machinery and agriculture, and the high-yield and normalized seeding.关键词
