摘要
1990年起 ,采用浮床无土栽培技术在鱼塘水面种植陆生植物美人蕉 (CanageneralisBailey) .结果表明 ,美人蕉对水栽表现出良好的生态适应性 .水栽美人蕉单位面积生物产量比陆栽增加了 5 0 %左右 ,开花量增加近1倍 .水栽美人蕉花期比同期的陆栽美人蕉延长 2 1d .水栽美人蕉的良好适应性还表现在它的分枝根多 ,根系活力强 ,白根所占比例较高 .图 1表 4参
Canna ( Cana generalis Bailey) plants were cultured on fish pond by floating beds without soil from 1990 to 1995 in Fuyang County, Zhejiang. The results indicated that the canna plants grown in floating beds produced 52% more biomass than those in the soil. Besides, the former gave twice more flowers, flowering phase were 21 d longer, new root ratio was higher and root vigor was stronger comparing with the later. Fig 1, Tab 4, Ref 5
