12月20日托?？谡Z(yǔ)Task 6
In the lecture, the professor talks about two disadvantages of irrigation. The first one is that plants won’t grow properly when there’s too much water. Take soil growing plants like melons as an example, when the soil gets too wet, fungus starts to form, and it will keep melons from growing properly. That’s why the whole irrigation system has to be designed carefully to avoid this problem. The second disadvantage is that in low-rainfall areas, salt builds up in lakes, when there’s too much salt in water, it will be harmful to plants as well.
