近几年来,经过农业部门的努力,转基因抗虫棉已在广水地区大面积推广,但农民对抗虫棉的认识依然存在两种误区:一种认为既然是抗虫棉,那就是百虫不侵,不必防虫,只需防病;另一种认为抗虫棉根本就不抗虫,因此在病虫防治上同普通棉花一样对待。针对这两种错误认识,笔者通过1999～2001年连续3a对比观察研究,总结出了抗虫棉抗虫局限性及综合防虫措施,以便充分发挥抗虫棉的优势,保护生态
In recent years, through the efforts of the agricultural sector, GM cotton has been widely popularized in Guangshui area. However, there are still two misunderstandings about farmers’ awareness of cotton insects: one is that since it is insect-resistant cotton, it is a kind of insect No invasion, no pest control, just disease prevention; the other does not consider insect-resistant cotton pest, so pest control on the same treatment with ordinary cotton. In view of these two kinds of mistakes, through three consecutive observational studies from 1999 to 2001, the author summed up the limitations of insect-resistant cotton and integrated pest control measures in order to give full play to the advantages of insect-resistant cotton and protect the ecology
