不同密度对青贮玉米产量与品质的影响

Impacts of Different Densities on Yield and Quality of Silage Maize

青贮玉米不同密度下的子粒产量和品质测定结果表明,不同种植密度直接影响子粒的产量与品质,在一定的密度范围内,玉米子粒蛋白质、脂肪的含量在不同成熟阶段随密度的增加呈下降趋势。玉米子粒中蛋白质、脂肪的低含量与最高产量相对应,但玉米子粒中蛋白质、脂肪的高含量却不与较低产量相对应。

The survey of yield and quality of seed to different densities of the ensiling maize showed the intluence of different densities on the yield and quality was strong. Within certain density range, protein and fat of maize descend with the increase of the density in different mature stages. The little protein and fat correspond to highest yield, but the high protein and fat did not correspond to low yield.
