每年,人们都会对大大小小的河道进行疏浚,在河道疏浚的过程中会产生大量淤泥,即“疏浚土”。其实,疏浚土也是一种资源,如果能用其栽培植物,那么这将是一种理想的处理方案。和普通农田土相比,用疏浚土栽培出的植物,其长势会更好吗?带着这个问题,我在老师的帮助下进行了实验探索。 Every year, people dredge large and small rivers and dredge large amounts of silt, or “dredged soil.” In fact, dredging soil is also a kind of resource, if it can be used to grow plants, then this will be an ideal solution. Compared with ordinary farmland soil, the use of dredged soil cultivated plants, the growth will be better? With this question, I conducted experiments with the help of the teacher to explore.
