摘　　要：为了研究油菜昆虫授粉效果,在重庆地区开展昆虫授粉试验,测定油菜产量、结荚率、千粒重、角粒数4个指标。结果表明:授粉区样方产量、角粒数、千粒重与空白对照区均差异极显著(P<0.01),分别提高63.48%、14.85%、-18.69%。说明昆虫授粉对重庆地区油菜的增产效果显著。： To study the effect of insect pollination on rapeseed, an insect pollination test was carried out in Chongqing area, which was used for the determination of the four indicators including rapeseed yield, podding rate, thousand kernel weight and the number of seed per pod. The re- sults showed that the quadrat yield, seeds per silique and thousand kernel weight in the area of insect pollination were significantly different （ P 〈 0.01 ） compared with the blank control area, which increased by 63.48%, 14.85% , and - 18.69%, respectively. The results indicate that the insect pollination has an obvious effect on the increase of rapeseed yield in Chongqing area.
