攀西地区不同密度和施氮量对鲜食糯玉米叶片光合生理特性的影响

不同密度和施氮量下,鲜食糯玉米植株单株可见绿叶数和展开绿叶数、单株叶面积、叶面积指数、光合势、功能叶的叶绿素a、叶绿素b和叶绿素a b、功能叶净光合速率等变化均呈单峰曲线.单株可见绿叶数和展开绿叶数、单株叶面积、叶面积指数、光合势、功能叶的叶绿素a、叶绿素b和叶绿素a b、功能叶净光合速率等均随施氮量的增加而增加;但除叶面积指数、光合势随密度增加而增加,其余指标均随密度的增加而下降.

The Panxi Local Different Density and Nitrogenous Fertilizer Employment Quantity Characteristic Affects to the Fresh Food Glutinous Corn Leaf Blade Photosynthesis Physiology

The different density and under nitrogenous fertilizer employment quantity, the fresh food glutinous com adult plant single obvious green leaf number and launches the green leaf number, Single blade area, the leaf area index, the photosynthesis potential, function leaf' s chlorophyll a, chlorophyll b and the chlorophyll a b, the function leaf only photosynthesizes the speed and so on to assume the single peak change curve. The single obvious green leaf number and launches the green leaf number, Single blade area, the leaf area index, the photosynthesis potential, function leaf' s chlorophyll a, chlorophyll b and the chlorophyll a b, the function leaf only photosynthesizes the speed and so on to increase along with nitrogenous fertilizer employment quantity the increase; But eliminates the leaf area index, the photosynthesis potential increases along with the density increases, other targets drop along with the density increase.
