Question

如题所述

Answer 1

将所需的农药剂量彻底地混和到土壤中作为水溶液，以令农药稀释成可用的浓度，及土壤放入玻璃罐内。将十条蚯蚓放进内置测试基材的一升玻璃容器中。为防止蚯蚓逃脱，测试容器乃用带有集成纱布（+1 MM）的聚乙烯薄膜覆盖，以确保通风最佳。经过14天、21天孵化期后，存活的蚯蚓是由人手拣出。测试端点是死亡率。

原文如下：
The desired amount of pesticide was thoroughly mixed into soil as an aqueous solution to give the working concentration of pesticide, and soil was placed into glass jars. Ten adult worms were placed in 1-L glass containers filled with test substrate. To prevent the worms from escaping, test containers were covered with a polythene sheet with integrated gauze (+1 mm) to ensure optimal ventilation. After 14 d, 21 d of incubation, surviving worms were sorted by hand. The test endpoint was mortality.
