不同覆膜滴灌方式对玉米叶片光合特性的影响
Effects of Different Drip Irrigation of Maize Leaf Photosynthetic Characteristics
摘要
Abstract
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.关键词
