近几年,由于鼠害严重,为了消灭老鼠而施用的农药,反而间接毒杀吃它们的天敌,使老鼠失去天敌控制而更加繁衍成灾。 去年,五一节期间,我到田里播种春花生,发现地头有一条0.6米长左右的水蛇,因吞食被药死的田鼠而死于鼠洞旁。在另一个地头,一只小鸟因食用灭鼠麦粒而毙命。 In recent years, due to the serious pests of rats, the pesticides used to eradicate rats have indirectly poisoned their natural enemies, causing them to lose their natural enemies and become more prolific. Last year, during May Day, I went to the fields to sow spring peanuts and discovered that there was a water snake about 0.6 meters long at the top of the ground. He died of rat death by swallowing a dead field mouse. In another place, a bird died from eating rodent grains.
