笔者以10年生壶瓶枣为试材，研究了枣树在灌溉、未灌溉、遮阴、雾化栽培和喷施亚硒酸钠5个处理下光合作用的日变化规律。结果表明：干旱条件降低了树体的光合作用，通过遮阴、雾化栽培和喷施亚硒酸钠可以提高树体的气孔导度，调节叶片的蒸腾，提高树体的光合速率，保证光合作用的进行。亚硒酸钠处理显著提高了叶片上午的净光合速率，气孔导度和蒸腾速率都比其他处理高。
筆者以10年生壺瓶棘為試材，研究瞭棘樹在灌溉、未灌溉、遮陰、霧化栽培和噴施亞硒痠鈉5箇處理下光閤作用的日變化規律。結果錶明：榦旱條件降低瞭樹體的光閤作用，通過遮陰、霧化栽培和噴施亞硒痠鈉可以提高樹體的氣孔導度，調節葉片的蒸騰，提高樹體的光閤速率，保證光閤作用的進行。亞硒痠鈉處理顯著提高瞭葉片上午的淨光閤速率，氣孔導度和蒸騰速率都比其他處理高。

10a Huping jujube as material , daily variation of photosynthesis of jujube was studied , which cultivated under irrigation, no-irrigation, shade, atomization cultivation and spraying the sodium selenite .The results showed that drought condition reduced photosynthesis and shade , atomization cultivation and spraying sodium selenite could improve stomata conductance of tree , regulate transpiration of leaf and improve net photosynthetic rate of tree to promote the photosynthesis . Sodium selenite treatment improved significantly photosynthetic rate , stomata conductance and transpiration rate which was bigger than the other treatments in the morning .
