意大利蜜蜂为重庆地区油菜授粉增产效果研究

Study on the effect of pollination by Apis mellifera ligustica on increasing the yield of Brassica napus L. in Chongqing area

为研究意大利蜜蜂为重庆地区油菜授粉增产提质的效果,建立适宜重庆地区的油菜授粉模式,试验通过在重庆市荣昌县安富镇开展授粉效果研究,分析意大利蜜蜂为重庆地区胜利油菜授粉的效果,评价意大利蜜蜂授粉对胜利油菜籽产量、千粒重及油菜籽粗脂肪含量的影响。结果表明:经意大利蜜蜂授粉的胜利油菜籽平均产量为459.34 kg/亩(1亩≈666.7m^2),显著高于未授粉组239.56 kg/亩(P<0.05),授粉组与未授粉组的千粒重差异不显著(P>0.05),授粉组的油菜籽粗脂肪含量(42.98%)显著高于未授粉组(40.66%)(P<0.05)。可见,意大利蜜蜂能够显著提高重庆地区胜利油菜籽的产量与质量。

To study the effect of pollination by Apis mellifera ligustica on increasing the yield and improving the quality of Brasswa napus L. in Chongqing area, establishing a suitable pollination mode of Brassica napus L. in Chongqing area. The pollination test was conducted in Rongchang of Chongqing city, and then the effect of pollination by Apis mellifera ligustica on Brassica napus cv. Shengli in Chongqing area was analyzed, and the effect of pollination by Apis mellifera ligustica on the yield of rapeseed of Brassica napus ev. Shengli, thousand kernel weights, and crude fat content of rapeseeds was also evaluated. The results showed that the average yield of rapeseed of Brassica napus cv. Shengli pollinated by Apis mellifera ligustica was 459.34 kg/mu （one mu equals to about 667 square meters）, which was significantly higher （P 〈0.05 ） than that of the unpollinated group （239.56 kg/mu）. There was no significant difference in the thousand kernel weights between the pollinated and unpollinated groups, and the crude fat content of rapeseeds in the pollinated group （42.98%） was significantly higher （ P 〈 0.05 ） than that of the unpollinated group （40.66%）. The results indicate that Apis mellifera ligustica can significantly improve the yield and quality of rapeseed of Brassica napus cv. Shengli in Chongqing area.
