引进窄冠速生刺槐营造速生丰产林研究

A Test on Silviculture of Fast-growing and High-yield Plantation of Introduced Narrow Crown Fast-growing Robinia pseudoacacia L.

采取截杆栽植技术和不同栽植密度开展窄冠刺槐速生丰产林营造试验,结果表明:引进的新品系刺槐苗木能够适应宁夏地区立地条件和自然生长环境;应用截杆栽植技术能有效提高刺槐苗木造林成活率;并通过采取科学合理密植,能够取得较好的经济效益和生态防护效益。

An experiment was conducted on silviculture of fast-growing and high-yield plantation of narrow crown fast-growing Robinia pseudoacacia L. using trunk-cutting planting technology and different planting densities. The results show that the introduced new line of Robinia pseudoacacia L.seedlings could adapt to the site conditions and natural growth environmen of Ningxia area. The survival rate of Robinia pseudoacacia L.seedlings planted could be upgraded effectivly by using trunk-cutting planting technology. With this and adopting scientific and rational planting density a good economic benefit and ecological protective effect colud be achieved.
