| 摘 要： | 以优质杂交种雅玉青贮8号为材料,研究不同种植密度下青贮玉米生长变化以及对产量和营养成分的影响。结果表明:随密度增加,植株增高,茎粗变细,产量随密度增加有所上升,8.25万株/hm~2时产量最高。综合水分及粗蛋白、酸性洗涤纤维和中性洗涤纤维等营养成份含量分析,在8.25万株/hm~2和9.75万株/hm~2的种植密度下,其水分含量和营养成分含量比较合理。结合产量分析,8.25万株/hm~2的种植密度较能发挥雅玉青贮8号优质高产特性。

| Abstract: | Field experiments with silage cornYayu 8were carried out under 4 planting densities to study the effects of planting density on the growth,yield and nutrient content of the corn.The results showed that with the density increasing the corn increased in plant height and yield but decrease in stem diameter,and when the density was 82 500 plants/hm~2 the corn yield was the highest.The integrated analysis of moisture,crude protein,acid detergent fiber,neutral detergent fiber and other nutrient contents indicated... |
