1997年冬,我省降雪普遍较多,由于积雪量大且时间长、导致山、田鼠啮害果树现象大量发生。由于老鼠缘果树树于基部把表皮呈360°啮食净光、表皮下的导管、塞管全部被切断,无法输送水分和养分。第二年春季,大部分果树靠体内储存的那点养分,仅能维系开完花以后便枯萎、死亡。据九台市调查、这种现象不仅在成龄果园普遍存在,有的苗圃幼苗也有鼠害发生,给果农造成巨大的不可弥补的经济损失。 In the winter of 1997, snowfall in our province was generally more. Due to the large amount of snow and the long time, snowfall occurred in the mountains and voles. Due to the mouse margin of the tree tree at the base of the skin was 360 ° gobing net light, epidermal catheter, the tube was cut off, unable to transport moisture and nutrients. In the following spring, most of the nutrients that the fruit trees store in the body can only wither and die after the blooms are closed. According to the investigation of Jiutai City, this phenomenon is not only widespread in mature orchards, but some nursery seedlings also have rodent pests, causing huge irreparable economic losses to the growers.
