在科技活动中，毒瓶是一种快速杀死昆虫常见而有效的工具。但毒瓶中的毒液一般为乙醚或氯仿等剧毒物质，稍有不慎便会发生意外。我经过多次实验发现了一种替代品──龙骨汁。 龙骨是一种类似仙人掌的植物，主干笔直呈三棱形并连续分叉，且长有刺和叶，它分布十分广泛，生长快， In scientific and technological activities, poison bottles are a common and effective tool for quickly killing insects. However, poisonous liquids in poison bottles are generally highly toxic substances such as ether or chloroform. Accidents can occur accidentally. After many experiments I discovered a substitute - keel juice. The keel is a cactus-like plant. The main trunk is straight and triangular in shape and continuously bifurcates. It has long thorns and leaves. It is widely distributed and grows fast.
