利用矛盾,以虫治虫,在我国有着悠久的历史,远古时代即在生产实践中有所应用;《仪礼》所说的“迎猫以除田鼠”,体现了“生生相克”。13世纪时,元朝所编《南方草木状》中又首次记载了广东桔农利用惊蚁以除治钻蚀性昆虫,是世界上利用生物除虫的最早记录。在错综复杂的自然界中,相互制约、相互依存的自然现象,也是普遍存在着的规律。有害虫,相应就有益虫存在。就松毛虫来说,它虽然繁殖率很大,危害严重,但自然界中抑制它的天敌也很多,如果没有这种抑制作用,松树就不可能保存至今。利用矛盾,是争服自然的一种手段。毛主席教导我们:“人们为着要在自然界里得到自由,就要用自然科学来了
The use of contradictions to worm pest control in our country has a long history, that is, ancient times in production practice has been applied; “Ceremony” said “welcome cats in addition to field mice,” reflects the “life and death g”. In the 13th century, for the first time recorded in the “Southern Herb” by the Yuan Dynasty, Guangdong orange farmers recorded the first use of creatures in the world by using ants to kill boring insects. In the complicated nature, the natural phenomena that are mutually restricted and interdependent are also the universal laws. Pests, the corresponding beneficial insects exist. In the case of pine caterpillars, although it has a high reproductive rate and serious harm, there are many natural enemies that can suppress it. Without such inhibition pine trees can not be preserved. The use of contradictions is a means of conquering nature. Chairman Mao taught us: "People want to be free in nature, it is necessary to use natural science
