Abstract
Using main cultivated JinShan27 as test material and ordinary households maize as the control,we analyzed the material production ability of leaf of high-yield maize.The results showed that Leaf area index of high-yield maize was higher than control,and difference was obvious in bottom leaf.The net photosynthetic rate of high-yield spring maize was lower than control in Jjointing,which was contrary in Silking and Milking.Population leaf area duration(LAD) of high-yield maize was higher than control in the whole growth period,and which was maximum form Silking to Milking.The yield of high-yield maize was extremely significant higher than control,The number of productive ear was extremely more in Production factors,and Grain number per spike and 1000-grainweight was lower than control.
