The Study of the Different Density and Nitrogenous Fertilizer Employment Quantity Characteristic Affects to the Fresh-eating Waxy Corn Leaf Blade Photosynthesis Physiology

The indices changes the fresh-eating waxy corn 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 under different density and nitrogenous fertilizer employment quantity, assume the single peak change curve. The indexes 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.
