摘要
通过大田试验研究不同密度和氮肥水平对花生苗期根的影响。结果表明:氮肥施用量对根形态有明显影响,根长、根体积和根表面积都呈上升的趋势,氮肥促进了根干物质的积累,增加了根冠比;密度增加则抑制了根的生长和根干物质的积累。
A field experiment was set up to study the effect of different nitrogen application levels and density levels on root in peanut seedling stage.The results show that nitrogen application levels significantly influences root morphology,root length,surface area and volume rise with the increasing nitrogen dose,nitrogen increases the accumulation of dry weight and root to shoot radio,suggesting that nitrogen enhances root development.On the contrary,the increasing of density inhibits the root development.
