| 摘 要： | 以甘农118玉米为试验材料,于2013年和2014年在宁夏盐池进行了大田试验,设置单膜平作(single film mulching and flat planting,SFP)、双膜平作(double film mulching and flat planting,DFP)、柠条粉沟覆平作(Caragana intermedia powder ditch mulching and flat planting,CPDP)和裸地(Uncovered and flat planting,CK)4个处理,比较了其对旱地玉米生长、光合特性及水分利用效率的影响。结果表明,在降雨量较多和玉米生长末期,各处理玉米的株高、茎粗和叶面积间无显著差异(P0.05);在降雨量较少时,覆膜处理(SFP和DFP)各生长特性间显著高于CK和CPDP处理(P0.05),而CPDP和CK处理间则无显著差异(P0.05)。在玉米建植后的中后期,覆膜处理(SFP和DFP)光合速率和蒸腾速率高于CPDP和CK处理处理。总体看来,CPDP处理的水分利用效率(叶片水平和产量水平)均低于SFP和DFP处理。因此,不建议在研究区采取CPDP处理措施。

| Abstract: | Using the maize cultivar Gannong 118 as material,a field experiment was conducted in Yanchi County,Ningxia Hui Autonomous Region in 2013 and 2014,with the purpose to investigate the effects of different treatments,in eluding single film mulching and flat planting (SFP),double film mulching and flat planting (DFP),Caragana intermedia powder ditch mulching and flat planting (CPDP),and uncovered and flat planting (CK),on the growth,photosynthetic characteristics and water use egiciency (WUE) of dryland maize.The results showed that,when the rainfall was abundant,there was no significant difference in plant height,stem diameter and leaf area at late growth stage of maize among different treatments;however,when the rainfall was deficient,all the growth parameters of maize under SFP and DFP were significantly better than those under CK and CPDP (P ＜ 0.05),and there was no significant difference between CK and CPDP.In the middle and late period of maize,the photosynthetic rate and transpiration rate of SFP and DFP were significantly higher than those of CPDP and CK (P ＜ 0.05).The WUE (including both leaf WUE and yield WUE) of CPDP was generally lower than that of SFP and DFP.Therefore,CPDP is not suggested to be applied in the study area. |
