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。
In order to study the pollination effect of rapeseed insects, insect pollination test was carried out in Chongqing, and four indexes of rapeseed yield, pod rate, 1000-grain weight and grain number were measured. The results showed that there was a significant difference (P <0.01) between quadrat yield, grain number, 1000-grain weight and blank control area in pollination area, which increased by 63.48%, 14.85% and -18.69% respectively. This shows that insect pollination significantly rapeseed production in Chongqing.
