本研究以大豆吉育47为试验材料,通过盆栽土培法研究了施磷对水分胁迫下大豆光合特性的影响。结果表明,对大豆增施磷肥可以使干旱条件下大豆叶片的蒸腾速率降低,提高其光合速率、水分利用效率和产量得以提高。
In this study, Soybean Jiyu 47 was used as experimental material to study the effects of phosphorus application on the photosynthetic characteristics of soybean under water stress. The results showed that application of P fertilizer to soybean could reduce the transpiration rate of soybean leaves under drought condition and increase its photosynthetic rate, water use efficiency and yield.
