| 摘 要： | 以新植苹果 (Malus pumila Mill/ Malus hupenensis Rhed)幼树为材料 ,研究了植物生长物质和肥料对果树新根 (吸收根和延长根 )的诱导效应。结果表明 ,尿素、IBA和羊粪不论单用与合用均增加新根总数、提高根系活力、改变吸收根 /延长根数量比值。其中尿素主要增加延长根数量 ,降低根 /冠比。 IBA明显促进延长根加长生长 ,提高根 /冠比。羊粪主要增加吸收根数量 ,提高吸收根 /延长根数量比值 ,使新根分枝增多、鲜重增加、延长根加粗。尿素与羊粪合用 ,增加根鲜重但降低根 /冠比值。 IBA与羊粪合用提高吸收根 /延长根数量比值 ,增加根鲜重 ,但对根 /冠比值没有明显影响 ,因而地上地下生长均衡。

| Abstract: | The effect of plant growth substance and fertilizer on root formation was studied in new planted apple tree(Malus pumila Mill/Malus hupenensis Rhed).The results indicated that urea and IBA and sheep dung all increased the total number and activity of new roots and changed the ratio of absorbing root to extensive root obviously.Urea increaced the number of extensive root and decreased the ratio of root to shoot mostly.IBA lengthened the extensive root and increased the ratio of root to shoot obviously.Sheep dung increased the number of absorbing root and increased the ratio of absorbing root to extensive root,divided new root into many branches,increased the fresh weight of root and thichen extensive root.The fresh weight of root increased and the ratio of root to shoot declined after urea added to sheep dung.After IBA added to sheep dung,both the ratio of absorbing root to extensive root and root fresh weight was increased and the ratio of root to shoot had no change obviously. |
