▌作品介绍：有一天，我们一家在公园里游玩，妹妹看见许多粉红色的花朵，特别漂亮，就去摘了一朵，哪知道手上立即起了红疹，她哭了，当时把我们也急坏了。立即去找了医生，医生介绍，是夹竹桃液体沾在皮肤上引起的。回家后，我查阅了相关资料：生长在公园里、道路旁、河道边的夹竹桃，是最毒的植物之一，它的叶、树皮、根、花、种子均含有多种配醣体，毒性及强，甚至于造成人们生命安全。但它对有害病虫有较强的灭杀作用，具有很好的杀虫功效。于是我设计了一个《环保卫士—-夹竹桃配醣体提取机器》，用它来提取夹竹桃中的配醣体液体，加工成杀虫剂，喷洒在生了白粉蚧的蔬菜上，让蔬菜上面虫卵、幼虫、成虫自然死亡，甚至全部消失。既达到了生态灭虫的目的，也增加了菜农伯伯的经济收入。
此文自动翻译Introduction:One day, our family was playing in the park. When my sister saw many pink flowers, which were very beautiful, she went to pick one. How did she know that there was a rash on her hand at once? She cried, and we were in a hurry at that time. Immediately went to the doctor, the doctor introduced that it was caused by oleander liquid on the skin. After returning home, I consulted relevant information: Oleander growing in parks, roadsides and rivers is one of the most poisonous plants. Its leaves, bark, roots, flowers and seeds all contain many kinds of ligands, which are toxic and strong, even cause people’s life safety. But it has a strong killing effect on pests and diseases, and has a good insecticidal effect. So I designed an “environmental protection guard – oleander carbohydrate extraction machine” to extract the carbohydrate liquid from oleander and process it into insecticide. It sprayed on the vegetable which produced the white powder scale, so that the eggs, larvae and adults on the vegetable died naturally, or even disappeared completely. It not only achieves the goal of ecological pest control, but also increases the economic income of vegetable farmers.
