摘要
对渭北生草制苹果园0～100cm土层水分分析结果表明,生草改善了0～60cm土层的贮水能力,但随生草种类不同而存在差异,牧草与果树在20～40 cm土层水分竞争强烈,在苹果年生长周期中,春季阶段(3～5月),生草能加重果园失墒,而在6～7月,生草能够增加果园贮水,8～10月各样地均处于增墒期.
Analysis on soil moisture of apple orchards with interplanting herbage management in the Weibei Plateau showed that sod culture resulted in improving of water-storage capacity at the depth of 0~60cm layer in comparison with clean cultivation, but different herbage species had various impact on it. In the period of apple growing season ,water competition between apple trees and herbage presented in the 20~40cm layer in the spring (from March to May ) where the soil moisture decreased, however the water-storage increased from June to October .
