摘　　要： 分析了不同地区的营养期和开花期2个物候期的酸模的矿质元素含量、C/N比值和含水量。结果表明:酸模的矿质养分含量比较高,氮、磷、钾分别可高达4.34%、0.49%、5.29%;C/N比值小,含水量高达80%以上,利于酸模腐解,重金属含量低,是安全速效的热带绿肥。 In this paper the mineral element content, C/N ratio and water content of the nutrition and tlowenng period of two different developmental stages of the Rumex acetosa Linnaeus which were collected from different areas were analyzed. The results showed that R. acetosa was rich in mineral nutrient content, the content of N, P, K as high as 4.34%, 0.49%, 5.29 respectively. C/N ratio was low, water content as high as 80%, which is good for the decomposition, the heavy metal content was also low, so R. acetosa is a kind of safe and effective tropical green manure.

关 键 词： 热带绿肥 酸模 矿质元素 评价
