摘要 在桂西北天峨县高楼山林场境内,采用不同肥料配方(即:配比肥A为氮25.5%、磷5.3%、钾6.0%;硫酸铜0.2%、硫酸锌0.5%、硼砂1%;配比肥B为氮20.9%、磷6.0%、钾9.0%,硫酸铜0.2%、硫酸锌0.5%、硼砂1%;配比肥C为氮磷钾复合肥,总量为≥48%)对秃杉幼林进行施肥试验,探讨秃杉幼林生长的效果。结果表明:4 a生秃杉幼林平均地径为7.12~8.33 cm,平均树高为2.86~3.59 m,平均冠幅为1.92~2.39 m2,显示出配方B对秃杉幼林生长的效果较好。 In order to explore the effect of different formula fertilizations on growth of the Taiwania tlousiana planted young forest, fertilization experiment in Gaoloushan plantation TianE county of Northwest Guangxi. The author introduced three formula fertilizations, namely A was 25.5% of N, 5.3% of P, 6.0% of K; 0.2% of copper sulphate, 0.5% of zinc sulfate, 1% of borax ; B was 20.9% of N, 6.0% of P, 9.0% of K; 0.2% of copper sulphate, 0.5% of zinc sulfate, 1% of borax and C was N, P, K compound fertilizer, the total amount of ≥ 48%.The results showed that the average diameter of 4 a of young Taiwania llousiana were 7.12 - 8.33cm, the average tree height were 2.86 - 3.59m while the average crown were 1.92-2.39m2. The overall, the effect of formula B was more significantly.
