直播油菜是在前茬水稻收割后,抢墒用复式播种机一次浅旋开沟或用旋耕机浅旋,然后将菜籽拌尿素后,条直播于田间的一种油菜种植方式。从1995~1997两季试验看,直播油菜显示出其良好的产量潜力和应用前景。为探索直播油菜在本区的适宜密度,进行了本试验。
Live rapeseed rapeseed is harvested in the field after the harvest in the past, grab water with a double seeder shallow ditch or rotary trowels shallow, and then the rapeseed mix urea, the strip live in the field of a rapeseed planting. From 1995 to 1997 two seasons see the test, direct seeding rape showed its good yield potential and application prospects. In order to explore the suitable density of live rapeseed in this area, this experiment was conducted.
