由于生态平衡不断遭受破坏,近年鼠害比较严重。特别是早稻育秧期间,老鼠对秧苗的危害更大。因为此时野外鼠粮奇缺,早稻秧苗遭受老鼠危害使首当其冲。轻者局部被糟踏,重者全田秧苗被毁灭。老鼠危害秧苗不仅仅是前期,中后期也常遭受危害,前期老鼠吃掉种谷,后期则将秧苗从泥里拔出浮于水面,使秧苗无法扎根生长。
As the ecological balance continues to suffer damage, rat damage is more serious in recent years. Especially in the early rice seedling, the greater harm to the seedlings of mice. Because of the shortage of wild rat food at this time, early rice seedlings suffered the brunt of mice bear the brunt. Part of the light was bad, most heavy field seedlings were destroyed. The harm of the seedlings of mice is not only the early stage, but also often endangered in the late period. Early stage mice eats the seed valley, and in the later stage the seedlings are pulled out of the mud and floated, making the seedlings unable to take root.
