研究了麦后复播油葵不同品种、密度和施肥等栽培技术。筛选出高产油葵杂交种G101,该品种分别比汾葵6号、汾葵3号和内葵3号增产8.7%,12.9%和55.2%。随着密度增大,油葵盘径变小,每盘粒数和千粒重降低,单盘产量降低。适宜种植密度为52500~60000株/hm2。蕾期追肥比花期追肥增产11.8%
The cultivation techniques of different varieties, densities and fertilizers of wheat sunflower were studied. The high yielding oil sunflower hybrid G101 was screened, which was 8.7%, 12.9% and 55.2% more than fenhui 6, fenhui 3 and yankui 3 respectively. With the increase of density, the diameter of oil sunflower became smaller, the number of grains per panicle and grain weight per thousand decreased, and the yield of single disk decreased. Suitable planting density of 52500 ~ 60000 plants / hm2. Budding topdressing than flower topdressing 11.8%
