In order to reveal the drought resistance and adaptation of the C(4) desert plant Haloxylon ammodendron under artificially controlled soil moisture regimes, representative plants were selected to measure canopy photosynthesis using canopy photosynthetic measurement system. The results showed that appropriate soil moisture significantly enhances the canopy and leaf photosynthetic capacity, and extremely high soil moisture is not conducive to the photosynthesis of H. ammodendron.
为了揭示人工控制土壤水分条件下 C(4) 荒漠植物梭梭的抗旱性和适应性，选择有代表性的植株，利用冠层光合测量系统测定了其冠层和叶片的光合特性。结果表明，适宜的土壤水分显著提高了梭梭的冠层和叶片光合能力，而极度高的土壤水分不利于梭梭的光合作用。
