摘　　要：对近年新引进的互叶白千层苗期和幼林生长效应的研究结果表明：在引种区苗期以湿润沙质壤土生长最好；盆栽施肥在本试验条件下以Ｎ：０．５～１．０，Ｐ：０．６～０．９，Ｋ：０．８～１．２ｇ／盆为适宜施肥量；造林时，施基肥与不施基肥生长差异显著；林地施不同追肥２个月后，根据树高、地径、地上部分生物量得出的施肥效果排序为：复合肥Ⅱ＞复合肥Ⅰ＞碳氨＞尿素。Pot culture experiments were conducted to examine the response of Melaleuca alternifolia seedlings to soil texture and soil moisture content ,and the effect of different ratio of N、P、K on the growth of seedlings of the species. It was found that sandy soil was suitable for the seedlings′ growing and they throve well on damp soil. It was recommended that the combination of N:0.5～1.0,P:0.6～0.9,K:0.8～1.2(g/pot) was appropriate for the growth of seedlings of the species. Field studies were also carried out to access the effect of basal dressing and five treatments of top dressing. The result showed that basal dressing exerted tremendous effect on the growth of the young trees.It was concluded that the application of compound fertilizer Ⅱ(N 16%、P 16%、K 16%)with the dosage of 100 g/tree was the best for the growth of M. alternifolia among the five treatments of top dressing.
