【Abstract】 Taking Osmia cornifrons as material,the effects of Osmia cornifrons on the yield of seed production of cabbage in net houses was analyzed by plot comparative test.The results showed that Osmia cornifrons could well adapt to the net house environment for breeding cabbage and perform stable pollination results.And the yield and purity of the cabbage seeds produced by Osmia cornifrons were higher than those of the artificial pollination by 29.8% and 3.9% respectively,and the pollination cost significantly reduced.更多还原
