摘　　要：通过对"绿肥1号"不同生长期根、茎、叶器官产青量研究表明:茎、叶是"绿肥1号"主要产青器官,约占植株总产青量的80%～90%。各器官不同时期氮含量以叶片最高,为4%～6%,茎次之,根部氮含量最低。各时期钾含量以叶片含量最高,依次为茎、根。而磷含量6月中下旬以叶片最高,7月下旬至8月下旬以茎最高,9月份以根含量最高。The yield of ＂Green Manure 1#＂ come from Leaf and stem ,weight of leaf and stem is about 80%～90% of plant’s weight after investigating yield and nutrition concentration through the growth period. Nutrition is different from different organ of ＂Green Manure 1#＂,Nitrogen concentration in leaf from 4% to 6%,that of stem is lower,and root is lowest. Potassium concentration of leaf,stem and root is respective as leaf stem root. Phosphorus concentration is highest in leaf in the last ten-day period of June,that of stem is highest from the last ten-day period of July to August,that of root is highest in September.
