| 摘 要： | 在盛夏干旱期，猕猴桃园行间百喜草覆盖（Covering)与株间百喜草敷盖（Mulching)可以降低地表温度，根际土温与冠幕气温，有效保持土壤含水量及冠幕空气相对湿度，随干旱期的持续延长，猴猴桃园土壤含水量，叶片水势，叶片光合速率均逐渐降低，而进喜草覆盖与敷盖可在一定程度上延缓它们的下降。

| Abstract: | During the dry season of mid-summer, the water content of soil and relative moisture in the canopy were maintained effectively, and the soil layer temperature, soil temperature in the root region, air temperature in the canopy, were reduced obviously by covering and mulching the space between the rows with Bahiagrass. As the period of high temperature and drought were prolonged, all of the water content of soil, leaf water potential and photosynthetic rate of Kiwifruit trees were decreased gradually. Bahiagrass covering and mulching could delay their decline to some extent. |
