Well, I don't know if you know about this, but in California, there's a huge amount of plastic that's used in fields right now as plastic mulch, and this is plastic that's making these tiny little greenhouses right along the surface of the soil, and this provides warming the soil to increase the growing season, it allows us to control weeds, and, of course, it makes the watering much more efficient.
我不清楚你是否知道， 在加州，有大量的塑料 用于地膜， 这些塑料就在制造这些小型的温室 是在地表面， 也提供了土地的温暖从而增加了生长季节， 也允许我们控制杂草， 当然，也有效地利用了水分。
