【摘要】 为解决油菜杂交制种中的效率低、质量差问题,应用壁蜂对油菜杂交制种进行辅助授粉。通过对壁蜂生物学特性的连续观察及其在油菜制种授粉上的应用研究分析,结果表明,壁蜂的活动周期与油菜花期吻合性好,适用度高,不仅适合油菜大面积制种应用,而且适用于小面积网棚应用。每平方米投放10~15头壁蜂、巢箱高度1.0~1.5 m,可有效解决油菜制种过程中的串粉、用工多、结实率低等难题,是有效提高油菜制种质量和产量的一种新方法。更多还原

【Abstract】 In order to solve the problem of low efficiency and poor quality in hybrid seed production of rapeseed, application of Osmia auxiliary pollination on the production. Based on studying the biologicalcharacteristics of Osmia and its application in rape seed(Brassica campestris L.) pollination, we find that Osmia activity cycle had a good match with rapeseed flowering time. It’s not only suit for large area rape seedproduction, but also suit for small net tent application. It would be a good method for improving the quality andquantity of rape seed hybrid output, can effectively solve the difficult problems of mix, work hard and low seedsetting rate in the hybrid production process, with 10-15 Osmis in every square meter, and the nest box underthe condition of 1.0-1.5 m height.更多还原
