调查表明蘑菇房害鼠种类与农田相似 ,黄毛鼠为优势种 ,占 88.7%。害鼠侵入菇房为害的时间、数量受气候影响较大。害鼠迁入菇房高峰期 ,1 1月份为 1 9∶0 0～ 2 0∶0 0时 ,其数量占当夜迁入总量的 71 .5 % ,1 2月份随着气温的下降 ,迁入高峰期为 1 7∶0 0～ 1 8∶0 0时 ,其数量占当夜迁入总量 72 .8%。蘑菇房内鼠害面积分布 ,以第四层菇床居重 ,第二层最轻。害鼠对蘑菇各生育期均造成不同程度的危害 ,受害面积以复土期和第三潮菇最大 ,产量损失率以第二潮和第三潮为重 ,分别达 5 6 .48%和 6 9.75 %。
Survey shows that the type of mushroom house rats and farmland is similar to Rattus rat dominant species, accounting for 88.7%. Harmful rats invaded mushroom house damage time, the number affected by the climate. When the pest moved to the mushroom house peak, 1 January was 1 9:0 0 ~ 2 0:0 0, accounting for 71.5% of the total amount of the night moving into the night. As the temperature dropped in January, Into the peak of 1: 7: 0 ~ 1 8: 0 0, the number accounted for the total amount of moving into the night 72.8%. Mushroom room rat damage area distribution, to the fourth floor of mushroom bed weight, the second floor of the lightest. Harmful rats caused different degrees of harm to the growth period of mushrooms. The affected area was the largest in the period of returning to soil and the third tidal mushroom. The yield loss rate was the second tide and the third tidal wave, reaching 56.68% and 6.6% 9.75%.
