| 摘 要： | 对甘肃天祝金强河高寒地区不同生境下金露梅叶、茎，根和整株的热值及其季节动态进行研究的结果表明，生长季（４￣１０月）叶、茎、根和整株的干物质平均热值分别为２０１７１．９、２０６３４．８，２０７７９．８，２０６９７．２Ｊ／ｇ。金露梅整株的热值在生长季呈Ｖ型变化；可用线性方程Ｙ＝１０５８．１－３８．６３６Ｔ表达（ｒ＝－０．９５８，Ｙ为热值，Ｔ为月均气温），金露梅各器官的热值在时间上具有同步性，不同生境下

| Abstract: | Mean calorific values of leaf, stem, root and whole plant were 20 171.9, 20 634.8, 20 779.8 and 20 697.2 J/g DM respectively in growth season. Calorific value of whole plant could be described as Y=1 058.18-38 636T(Y was calorific value and T was mean month temperature). The calorific value in different organs showed the same dynamic and there was significant difference between calorific value of Dasiphora (Potentila) fruticosa living the different ecological environment. |
