在我国，随着规模化、产业化、区域化及设施农业的兴起、大面积种植单一作物品种，在花期较为集中、花量大的情况下，由于授粉昆虫虫源不足，造成不能满足作物授粉的需要。花期授粉不足，将导致产量和质量的严重下降，因此解决作物花期授粉不足问题无疑将是获得增产增收的重要
In our country, with the development of large-scale, industrialization, regionalization and facility agriculture, large-scale planting of single-crop varieties can not meet the requirements of crop pollination due to insufficient insect pollination due to relatively concentrated flowering and large flowering. Need. Inadequate pollination during flowering will lead to a serious decline in yield and quality, so resolving the problem of insufficient pollination at the flowering stage of the crop will undoubtedly be an important factor for increasing yield and income
