通过麦后夏播油葵的品种筛选、种植密度及施肥试验等 ,研究影响夏播油葵生长发育的因素。结果表明 ,高产油葵杂交种 G1 0 1产量达 2 4 63.0 kg/hm2 ,比其它品种增产 8.7%～ 55.2 %。夏播油葵适宜种植密度为 52 50 0～ 60 0 0 0株 /hm2 ,蕾期追施氮磷肥比花期追施增产 1 1 .8%。 The factors affecting the growth and development of summer sowing oil sunflower were studied by screening wheat varieties, planting densities and fertilization experiments. The results showed that the yield of high yielding oil sunflower hybrid G1 0 1 reached 2463.0 kg / hm2, which increased 8.7% -55.2% more than other varieties. Summer planting oil sunflower suitable planting density of 5250 0 ~ 60 0 0 0 plants / hm2, buds topdressing nitrogen and phosphorus fertilizer than the topdressing flowering 11.8%.
