过去,家乡的农民都是用壶点浇给玉米施氨水,挥发出来的氨令人没法喘气,眼泪直流。这不仅浪费肥料,还影响人的健康。我下决心要制造一种点施氨水的工具,使之既能使用方便又能避免氨水呛眼,还能让氨水不损坏庄稼。我的想法得到了老师的支持。在老师的指导下,经过几个月的反复实践和不断改进,我终于发明了“氨水点施器”。 In the past, peasants in their hometowns used pot water to pour ammonia into the corn. The volatilized ammonia was no way to breathe. This not only wastes fertilizer but also affects people’s health. I am determined to create a tool that applies ammonia water, so that it can be used easily and avoid ammonia blinking, but also allows ammonia to not damage crops. My idea got the support of the teacher. Under the guidance of the teacher, after several months of repeated practice and continuous improvement, I finally invented the “ammonia dispenser.”
