Chinese. 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。

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 NPKNKNPPK.
