| 摘 要： | 以赣红麻一号为材料进行了红麻苗期12种主要矿质元素缺乏研究。结果表明：缺N、Ca、Mg、Fe、S、B等对植株上部症状影响明显，表现生长缓慢、叶数少，叶色失绿等，所有缺素处理叶鲜重均为对照的70％以下，其中缺Ca、缺Mg处理仅为CK的7．5％和19．5％；缺N、Ca、Mg、S、Mo等对根量有明显影响；缺N、P、Ca、Mg、Mo等对干物质积累与CK相比有明显差异。

| Abstract: | The study on lacking 12main mineral e lements of Hi biscus cannabinus L.in Seedling period indicated that the symptoms o f the grou nd part were evident when la cking N,Ca,Mg,Fe,S,B.It grew slowly,less lea ves and losed green,the weight of fresh leaves of all treatments is 30percent lower than CK,with Ca,Mg only 7.5percent a nd 19.5percent of the CK.L acking N,C a,Mg,S,Mo had ob-vious impact on quantity of roots.Lacking N,P ,Ca,Mg,Mo had obvious impact on dry mass accumulation |
