| 摘 要： | 为优化太子山树种林种结构,进行了兰考泡桐引种栽培试验。苗木截干后栽植,设置了株行距为3 m×3 m和2 m×3 m的初植密度试验。经当年平茬及第3年间伐强度为40%和第5年隔行间伐的透光伐,对不同密度的兰考泡桐6年生长情况进行了分析。结果表明:兰考泡桐在试验区引种栽培初步成功,树高、胸径和单株材积年均生长量分别达到2.09 m、3.28 cm和0.024 0 m3,明显优于当地杉木二代林的生长量,表现出速生丰产的特点;栽植密度对兰考泡桐的胸径和材积生长有显著影响,以3 m×3 m或密度更大的林分生长较好。

| Abstract: | In order to optimize the tree species and improve the forest structure of Taizi Mountain Forest Park,Experiment of planting density(including 3 m×3 m and 2 m×3 m) with truncated stem was performed on cultivation Paulownia elongata S.Y.Hu.And then stumping,40% thinning and 1/2 line-thinning respectively in the first year,the third year and the fifth year,were treated.The results of growth of six years old stand indicated that P.elongata was introduced preliminary successfully.It showed fast-growing characteristics with height of 2.09 m,DDHB of 3.28 cm and volume of 0.024 0m3,which far surpassed the second rotation Chinese fir plantation locally.The differences of DDBH and volume growth were evidently with different initial density treatments.Low density(3 m×3 m or higher) in the plantation might promote the growth of P.elongata.The results also provided a basis for high-yield cultivation techniques of P.elongate in the northern margin area of Jianghan Plain. |
