| 摘 要： | 以郑单958为试验材料,在已经定位研究28年留茬深松(DT)、免耕(NT)、翻耕(PT)和传统耕法(CT)的基础上,探讨不同耕作方式对玉米叶片光合特性的影响。结果表明,不同耕作方式下玉米叶片的净光合速率(Pn)处理间存在差异,DT处理比NT、PT和CT分别高8.78%、25.50%和48.13%,NT处理比PT和CT分别高15.38%和16.00%,PT处理比CT高0.54%,DT和NT处理分别与CT差异达显著水平(p<0.05),其他处理间差异不显著(2010年);气孔导度(Gs)、胞间二氧化碳浓度(Ci)、蒸腾速率(Tr)和水分利用效率(WUE)处理间存在差异,差异不显著。

| Abstract: | Zhengdan958 was chosen as experiment material, the impacts of long-term (28 years) deep tillage with high stubble, no-tillage, plow tillage and conventional tillage on maize photosynthesis were assessed. The test results showed that there were different leaf photosynthesis rates of maize among different tillage, leaf photosynthesis rates on deep tillage(DT) 8.78%, 25.50% and 48.13% higher than on on-tillage(NT), plow tillage(PT) and conventional tillage(CT). Similarly, leaf photosynthesis rates on NT were 15.38% higher than on PT and CT. Besides, leaf photosynthesis rates on plow tillage were 0.54% higher than on conventional tillage. However, Gs, Ci, Tr and WUE of maize leaf were different among tillage, but, there were not significant. |
