摘要
利用7种填充剂,在室温和冰箱(5℃)内贮存,低温贮存25个月,白僵菌孢子萌发率为96.2％-98.2％;用黄土、活性炭、沙子、炉灰渣和草炭等填充剂的白僵菌室温贮存19个月,孢子萌发率为90.3％-95％。随着填充剂种类和贮存期的不同,孢子萌发率有差异。黄土填充剂有效贮存期最长达21个月;玉米轴粉、豆秸粉有效贮存期为9个月;对照有效贮存期为3个月。
Beauverin bassiana spores with 7 diluents were separately reserved in freezer at 5℃ and indoor for 25 months. The ratio of germinating spores was 96.2%-98.2%. Spores diluted with loess, active carbon, sand, slag, turf and so on were reserved at natural temperature indoor for 19 months and the ratio of germinating spores was 90.3%-90.5%. The ratios of germinating spores were different among treatments with different diluents and reserved time. The longest valid reserve time of spores diluted with loess was 21 months, while that with corncob or legume straw power was 9 months and the control was 3 months.
