| 摘 要： | 传统的桉树经营措施一般只追肥到2-3a,本文对桉树4年生左右的近熟林追肥的效果进行了研究,追肥8个月后的结果表明追肥林比对照平均提高产量1.42m3/667m2,可实现纯利润278.02元/667m2;近熟期的追肥对不同的品种的增产效果不同,其中LH1增产1.78m3/667m2,U6增产1.50m3/667m2,W5增产0.96m3/667m2。追肥的增产效果说明,对近熟林追施肥是挖掘桉树速生潜力的有效技术措施。

| Abstract: | Fertilizer was only applied to 2-3 years old eucalypt plantation in traditional management. In this paper we had studied the effect of fertilizer application to about 4-year old eucalypt plantation. The results of 8-month after the fertilization showed: an 1.42 m3/667m2 volume increment had been achieved comparing with the control, the additional fertilizer had different effects on different eucalypt clones. The volume increments on clone LH_1,U_6 and W_5 were 1.78 m3/667m2,1.50 m3/667m2 and 0.96 m3/667m2 respectively.To apply additional fertilizer on near-mature eucalypt plantation was an effective measure to explore the growth potential of eucalypt. |
