向日葵,又叫葵花,其主要靠昆虫授粉才能结实。如今,大田作物大量使用农药,能为向日葵授粉的昆虫大多被农药杀死,能存活的已经很少。如果向日葵授粉不好结实率很低,秕子多,直接影响果实质量和产量。租用蜜蜂为向日葵授粉可提高产 Sunflower, also known as sunflower, pollinated mainly by insects to be strong. Today, field crops are heavily used in pesticides. Insects that pollinate sunflowers are mostly killed by pesticides and few have survived. If sunflower pollination is not good seed setting rate is very low, prickly heat, a direct impact on fruit quality and yield. Renting bees for sunflower pollination can increase production
