为进一步明确不同覆膜滴灌方式的光合特性和增产机理,2012年至2013年间,试验以春玉米为材料,对照为不覆膜滴灌,研究了4种覆膜滴灌方式对玉米净光合速率(Pn)、蒸腾速率(Tr)、气孔导度(Gs)、胞间CO2浓度、叶片瞬时水分利用效率(WUEi)、SPAD、荧光参数和籽粒产量的影响。结果表明,QM、KM、SM、JM处理的Pn、Tr、Gs、WUEi、SPAD、荧光参数和籽粒产量均显著高于 CK,呈极显著正相关关系。4个覆膜滴灌方式的产量较CK增产7.6%~28.5%,其中增产幅度最大的为 QM,较CK增加28.5%和18.3%,其次是 KM,较 CK增加24.0%和12.2%,是该地区最佳的覆膜滴灌方式。

In order to further clear the photosynthetic characteristics and production mechanism of the different effect of drip irrigation,during 2012 and 2013,this experiment by spring maize as material,effects of drip irrigation for comparison, studied the four kinds of effect of drip irrigation on maize net photosynthetic rate (Pn), transpiration rate (Tr),stomatal conductance (Gs), intercellular CO2 concentration,leaf instantaneous water use efficiency (WUEi),SPAD and fluorescence parameters and the influence of the grain yield. Results indicated that the QM,KM,SM,JM treatment of Pn,Tr and Gs,WUEi,SPAD,fluorescence parameters and grain yield were significantly higher than that of CK, it showed very significant positive correlation, 4 drip irrigation mode of yield increased by 7.6%~28.5% than CK, one of the biggest increase rate of QM, increased by 28.5% and 18.3%than CK, followed by KM, increased 24.0%and 12.2%than CK. It was the best way of drip irrigation in this area.
