| 摘 要： | 依据前期研究成果，在红壤坡地果园内全园覆盖百喜草(Paspalum notatum Fliigge)可以取得良好的水土保持效果。本研究通过标准径流小区翔实的观测数据，通过对百喜草、狗牙根(Cynodon dactylon)、宽叶雀稗草(Paspalum wettsteinii Hackel)3个草种进行全园覆盖与带状覆盖下的水土保持效应试验，得知3个草种均能有效地遏制水土流失，特别是百喜草水土保持保效应最优。

| Abstract: | From the preliminary conclusion that in the red-soil slopeland orchards overall-covered with Bahia grass (Paspalum notatum Fliigge) is of the lowest surface runoff and soil erosion, where the soil and water conservation effect is good. Based on the analysis of the accurate observational data on standard runoff plots with various grass practices were carried out. The results showed that Bahia grass was the optimal grass for soil and water conservation, others which were effective were Cynodon dactylon and Broadleaf paspalum (Paspalum wettsteinii Hackel). |
