大部农作物都需要昆虫授粉。这些作物的产量首先取决于授粉昆虫的活动。授粉不良,即使有良好的土壤耕作、施肥灌水和植保等技术,也不能取得理想产量。巨大的经济组织使植物群落和授粉昆虫结构发生显著变化。由于田块的扩大,道路和田界面积随之缩小,大多数野蜂营巢处所变少;此外,机械或化学除草使开花杂草(蜜蜂食物)减少;开花杂草与大田作物同时开花,野生授粉昆虫比原来混杂地块上分布的范围更广。
Most crops require insect pollination. The yield of these crops depends first and foremost on the activities of pollinating insects. Poor pollination, even with good soil cultivation, fertigation and plant protection technologies, can not achieve the desired yield. Huge economic organizations make a significant change in the structure of plant communities and pollinating insects. Due to the expansion of plots, the area of roads and fields narrows, and most wild bee camping spaces become less. In addition, mechanical or chemical herbicides reduce flowering weeds (bee food); weeds and field crops bloom at the same time and wild Pollinating insects than the original mixed plots on the distribution of a wider range.
