同等立地条件下9个杨树品种材积成熟龄对比

Study on the Mature Age of Volume of 9 Poplar Varieties

通过调查107、中林46、中荷1号、土耳其、72、69、南林95、南林895、丹红杨9个杨树品种1-8年生的材积,以常见栽植密度3 m×3 m为标准栽植密度,选取平原浇灌便利地块为标准地块进行相关试验。结果表明,9个品种的杨树在当地的最佳优选顺序依次为南林895、南林95、107、中荷1号、丹红杨、中林46、69、72、土耳其;栽植5-6年即可采代的南林895、南林95、107、中荷1号、丹红杨可取得最佳年化经济效益。

Taking the common planting density of 3 m ×3 m as the standard planting density and the plain irrigation convenient plot as the standard plot, the related experiments were carried out by investigating the volume of 9 poplar varieties(1-8 years old) of 107, Zhonglin 46、Zhonghe 1、Turkey、72、69、Nanlin 95、Nanlin 895 and Danhongyang. The results showed that the local optimum order of poplar of 9 varieties was Nanlin 895、Nanlin 95、107、Zhonghe 1、Danhongyang、Zhonglin 46、69、72、Turkey. The best annual economic benefit can be obtained by planting Nanlin895、Nanlin 95、107、Zhonghe 1、Danhongyangwhich can be cut in 5-6 years.
