山地杨栽植技术研究

Study on Planting Technology of Populus maximowiczii Henry×Populus deltoids Marsh

为探索山区杨树造林的最佳方式,提高造林成效,2002年3月在建始县高坪镇采用带根苗造林、截干苗造林、插干苗造林3种不同的栽植方式对MD19等10个无性系进行对比试验。结果表明:采用带根苗造林的效果最好,造林后能迅速成林,成活率、保存率均高,生长最好;无性系中以MD19、MD110生长最快,在生产中可以大面积地推广应用。

Mountain soil thickness between 40~60 cm,In order to explore the best way to mountain poplar plantation,Improve the effectiveness of afforestation.In March 2002 the Jianshi County Gaoping Town of use with rooted planting,planting seedlings cut dry,dry plug seedlings planted three different planting methods on the MD19 in 10 clones to compare test.The results showed that use with a rooted forest of the best,afforestation after can rapidly established forest,survival rate,saving rates are high,the best growth;Clones in the MD19,MD110 fastest growing,In the production of large area application
