【摘要】 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 %。更多还原

【Abstract】 Through investigation, it is known that rat kinds in mushroom house are similar to those on farmland. Rattus rattoides account for about 88.7% being the domoinants. The time and quantity of rats invating mushroom house to do harm, are greatly affected by climate. In November, the climax time is from 19∶00 to 20∶00, and the quantity accounts for 71.5% of the total in the whole evening, in December, with dropping of temperature, the climax time is from 17∶00 to 18∶00, and the quantity accounts for 72.8%. The damage by rats is the most serious in the fourth floor, and is the lightest in the second floor. Rats cause different damage during different growth periods of mushroom, the damage area is the most broad during the soil covering period and the third harvest period, the yield loss is the largest during the second harvest and third harvest periods, reaching 56.48% and 69.75% respectively.更多还原
