Result With young elm forest-pumpkin strip intercropping, since the branch tendril covered the gap between pumpkin planting-ditches and elm forest land, the soil moisture was remarkably increased. And the water use efficiency under intercropping increased by 23.7%-163.3% compared with the sole cropping. Elm-pumpkin strip intercropping changed the sequential succession trend of the grasses growing in the gap of the pumpkin planting-ditch, annual grasses became the dominant vegetation, and the feeding nutrient matter content and yield of the annual grasses increased significantly.
