| Abstract: | The research results were as follows:When alfalfa was planted on red soilhilly land lacking of nitrogen in Jiangxi Province,applying nitrogen fertilizerat the seedling stage could promote the growth of alfalfa.Applying urea at therate of 5/mu once,its average individual height,root length and individualnodule amount at the flower stage raised 32.5%,22.4%,and49.5%respectly ascompared with the control. |
