不同供水条件对大豆净光合速率的影响

Effects of Different Water Conditions on Soybean Net Photosynthetic Rate

对不同水肥条件下大豆叶片净光合速率进行了相关性分析,力求从影响作物光合作用的内因和外因入手,研究作物的光合生产机理,从而达到提高作物产量的目的。结果表明:在整个生育期内,不同水分处理大豆净光合速率在8:00、10:00、12:00、14:00、16:00、18:00时都表现出相似的规律,生育中期净光合速率最高,前期次之,后期最低。

The text that researched photosynthetic characteristic of soybean such as net photosynthesis rates. From the photo- synthesis＇ influence of inside and outside, studied farm crop to match production mechanism and exalted the yield of farm crop. The result showed that the net photosynthetic rate of different water have similar rule at 8：00,10：00,12：00,14：00, 16：00,18：00 during all growing period. The net photosynthetic rate of middle period is the highest,former period is second, and the last period net photosynthetic rate is the lowest.
