| 摘 要： | 地稔为野生多用途植物,摸清地稔的需肥特性是决定地稔人工栽培能否成功的关键,研究了在地稔人工栽培中N、P、K三要素对地稔的生长状况及植株养分分配的影响。结果显示:N、P、K均可以有效增加地稔的分枝数、叶片数、叶面积、开花量、结果数和干物量,且以N肥效果最明显, 其次是K和P肥,研究还发现三元素间配合施用具有相互促进吸收的作用,对促进地稔生长的效果更加明显,且养分配合效果大小依次是NPK＞NK＞NP＞PK。

| Abstract: | Melastoma dodecandrum Lou is a multi-purpose wild plant.Finding out the needed fertilizer characteristics is a key to success for artificial cultivation.Effect of N,P and K to Melastoma dodecandrum Lour growth and nutrient distribution under artificial cultivation was studied in this paper.The results showed that N,P,K can effectively increase Melastoma dodecandrum Lour’s branch umber,leaf number,leaf size,flowering capacity,fruit number and dry mater quantity.N fertilizer is the most effective,followed by K and P fertilizer.The study also founds that coordinated application of 3 elements can promote the absorption of each element,and the growth of Melastoma dodecandrum Lour.The cooperative effect of nutrients was NPK>NK>NP>PK. |
