摘　　要：以溪荪鸢尾品种"紫霞""紫蝶"为试材,分析了2种鸢尾干物质积累的规律,同时研究了氮(N)、磷(P)、钾(K)的吸收利用情况,并进行相关性分析。结果表明:干物质积累情况存在差异,"紫霞"整体呈现逐渐增加的趋势,8月10日出现最高值;而"紫蝶"干物质积累整体呈现出S型曲线变化;氮、磷、钾积累量在2种鸢尾体内差异性显著,同时2种鸢尾在氮、磷、钾养分的积累规律均呈现出N>K>P的特点;2种鸢尾干物质积累规律明显与氮、磷、钾积累显著正相关,相关性系数大小顺序均为N>K>P。An experiment was conducted to study the dry matter accumulation,nutrient uptake and the low of the distribution of two kinds of different types of Iris sanguinea Donn ex Horn.‘Zixia＇and‘Zidie＇,the relationship of the dry matter accumulation and N,P,K nutrient uptake results were discussed.The results showed that the dry matter accumulation of two kinds of the Iris sanguinea appeared different,dry matter accumulation of ‘Zixia＇increased in growth period,and had a single peak in August 10 th.Dry matter of‘Zidie＇accumulation appeared S-type curve.Many differences between the nutrient accumulation of primary organs in two varieties were seen in N〉K〉P features.The positive correlation was found NKP between the dry matter accumulation and nutrient accumulation.
