研究表明:在北京地区夏播的条件下,杂交油葵适宜密度一般为52500株/hm~2,适宜的除草剂为33%除草通(施田补)乳油2250～3300mL/hm~2对水375～450kg/hm~2喷洒地面。油葵种植应保证底墒水和现蕾水充足,有利于北京地区杂交油葵的生长,提高产量。
The results showed that the appropriate density of hybrid oil sunflower was 52500 plants / hm ~ 2 and the suitable herbicide was 33% under summer sowing conditions in Beijing. The optimal density of weed control was 2250 ~ 3300mL / hm ~ 2 for water 375 ~ 450kg / hm ~ 2 spray the ground. Sunflower oil should be planted at the end to ensure adequate water and bud water is conducive to the growth of hybrid sunflower in Beijing to improve production.
