| Abstract: | Based on the research in loess hilly-gully region,we selected the technology of "nature" for changing sloping fieldto terrace.The gradientof terrace was designed to 40-50 which closed to loess nature caesuraangle in engineering design.Then we planted many kinds of grasses in the terrace,through observing the soil physical properties and testing the grass growth,we firstly selectthree types of grass,which suitto grow on the soft ridge of field in loess terrace. |
| Keywords: | loess hilly-gully region soft ridge of field slope of ridge manual planting grass physic and chemistry properties |
