棉花是可以异花授粉的自花授粉作物,利用蜜蜂授粉能够帮助棉花减少脱落增加产量。据苏联试验,利用蜜蜂授粉比不利用蜜蜂授粉的,一般可增加成铃12—22.5%,同时棉铃重、衣分和纤维长度都有增加。蜜蜂为棉花授粉时,蜂群与棉田的距离一般以在50米以内适当,据苏联试验,蜂群距离棉田50米以内者较距离500米者每 Cotton is a self-pollination crop that can cross-pollinate. Using bee pollination can help cotton reduce shedding and increase yield. According to the Soviet Union test, the use of bees pollination than the use of bees pollination, can generally increase the boll 12-22.5%, while boll weight, lint and fiber length have increased. When bees pollinate cotton, the distance between bee colony and cotton field is generally within 50 meters, according to the Soviet Union test, the colony is within 50 meters from the cotton field more than 500 meters
