| 摘 要： | 通过对不同水土保持耕作下大豆叶片净光合速率、蒸腾速率的测定,结果表明:不同水土保持耕作下的叶片在整个生育期内净光合速率的变化趋势基本一致,在结荚期净光合速率达到最大,其中振动深松+行间覆膜+垄向区田和免耕秸秆覆盖的净光合速率明显高于常规耕作的净光合速率,分别是常规耕作的1.63和1.36倍;大豆叶片的蒸腾速率在花期达到最大值,最大值为9.56 mmol/(m2.s),振动深松+行间覆膜+垄向区田叶片比常规耕作的叶片蒸腾速率高1.15倍。从苗期到花期,由于叶片的净光合速率和蒸腾速率都以相近的速度增长,因而水分利用效率变化不大。

| Abstract: | The difference of the photosynthetic rate and transpiration rate of soybean was observed under different conservation tillage.The trend of the photosynthetic rate,whose soybeans were observed under different conservation tillage,is identical in the growing stage.The photosynthetic rate is the highest at pod stage,and that is obviously higher in ZDL and MQ than CK.It is separately 1.63 and 1.36 times than CK.The transpiration rate of soybean leaves is up to the highest figure at flowering stage,which is 9.56... |
