运用生化法防治各种病虫害,是现代农业植保的一个重要课题。它不仅能有效防治病虫害,而且能降低生产成本,尤其能减少环境污染,促进生态良性循环,生产更多无公害绿色食品,以满足社会生活需要。下面介绍几种生化防治病虫害的新方法。一、动物除草如将家兔放养到番茄园中,它们会迅速吃掉杂草,而对番茄却秋毫无犯。将白鹅放进棉田,白鹅会拼命残食杂草,而对具有特殊气味的棉株置之不理。采用这一方法,一般每只白鹅可以完成15亩棉田的除草任务。
The use of biochemical methods to prevent and control various pests and diseases is an important issue of modern agricultural plant protection. It not only can effectively prevent and control pests and diseases, but also can reduce the production cost, especially can reduce the environmental pollution, promote the ecological virtuous cycle, produce more pollution-free green food to meet the needs of social life. Here are some new methods of biochemical pest control. First, weeding animals such as the rabbit stocking tomato garden, they will quickly eat weeds, but no offense to the tomato autumn. Put the white goose in the cotton field, white goose will desperately eat weeds, but the special smell of cotton plants ignored. Using this method, each white goose can generally complete the weeding task of 15 acres of cotton fields.
