| 摘 要： | 以间套作小麦玉米、单作小麦和单作玉米为研究对象,通过田间试验研究了氮素水平对单作和间套作小麦玉米叶片叶绿素及品质的影响。主要结果为:在同一施氮水平下,间套作小麦旗叶叶绿素含量大于相应单作;单作和间套作小麦开花期旗叶叶绿素含量和蛋白质含量、沉淀值之间都呈显著正相关(r分别为0.960*,0.948*,0.968*,0.957*)。在相同施氮水平下,单作玉米叶绿素含量高于相应间套作玉米;单作和间套作玉米孕穗期叶绿素含量与其蛋白质含量之间也呈显著正相关(r分别为0.861*和0.870*)。 |
| 关 键 词： | 氮素水平 小麦玉米间套作 单作小麦 单作玉米 叶绿素 品质 |

| Abstract: | This study compared the effect of nitrogen levels on chlorophyll content and quality of wheat and corn in monocropping and intercropping through field experiment. The results showed that, with the same nitrogen application, chlorophyll content of intercropped wheat was higher than that of monocropped wheat, while chlorophyll content of intercropped corn was lower than that of monocropped corn. Moreover, chlorophyll contents of intercropped and monocropped wheat at anthesis were separately positively correlated to protein content and sedimentation value (r=0.960~*, 0.948~*, 0.968~*,0.957~*, respectively), and chlorophyll contents of intercropped and monocropped corn at booting stage were separately positively correlated to protein content(r=0.861~*,0.870~*, respectively). |
| Keywords: | nitrogen level wheat/corn intercropping monocropped wheat monocropped corn chlorophyll content quality |
