摘要：为掌握追肥量、时间与次数对柚木生长的影响,在2年生柚木纯林和柚木格木混交林中,进行了肥种[复混肥(N10-P10-K8)]、3因素(追肥量、时间与次数)、8处理的施肥试验。试验结果显示:3年生和4年生时,追肥量分别以1 000.0 g/(株年)和2 000.0 g/(株年)为最好,低于此量时树高、胸径生长量随追肥量的增加而增加,反之则树高、胸径生长量都有所减少;施肥时间5月的树高、胸径生长量好于6或7月;施肥次数2次的树高、胸径生长量大于1次,不同地块施肥效果不同,纯林与混交林施肥效果没差异。
In order to investigate the effects of top-dressing quantity,time and frequency on growth of Tectona grandis,the manurial experiments with compounded fertilizer（N10-P10-K8）,3 factors（top-dressing quantity,time and frequency） and 8 kinds of treatments in the pure forest of 2-year-old of Tectona grandis and mingled forest of Tectona grandis and Erythrophloeum fordii.The results show that the best amounts of top-dressing quantity were 1 000.0 g/tree per year for 3-year-old stand and 2 000.0 g/tree per year for 4-year-old stand;when the top-dressing quantity were lower than these levels,the increments of height and DBH would be increased with the addition of top-dressing quantity,the increments of height and DBH would be reduced when the top-dressing quantity were higher than these levels;the increments of height and DBH when the trees were fertilized in May were better than that in June or July,the increments of them when fertilized for two times were larger than one time,there were different effects of fertilization in different fields,there were no differences in fertilizing effects between pure forest and mingled forest.
