欧美杨无性系引种试验

在福建省建瓯市开展不同土壤条件下引种欧美杨107、108无性系,欧美杨与乡土速生阔叶树马褂木、枫香造林对比试验。结果表明:利用柑橘园迹地种植107杨、108杨,具有早期速生丰产性,其5年生时树高和胸径生长量以及单位面积蓄积远高于马褂木和枫香;施用垃圾肥、猪粪肥和复合肥等作基肥可促进欧美杨生长,但对于肥力较好的抛荒农田和果园肥效较小。

Populus canadensis Clone Introduction Experiment

Populus canadensis clones 107 and 108 were introduced in Jian'ou,Fujian under different soil conditions and the experiment of comparison between local fast-growing hardwood Liriodendron chinensis and Liquidambar formosana,and Populus Canadensis was developed.The results showed that:the citrus orchards was planted Populus canadensis 107 and 108,which owned the fast-growing and high-yield characteristics at the early stage,its 5-year-old tree height and diameter growth and stocking per unit area were much higher than Liriodendron chinensis and Liquidambar formosana;the application of waste manure,pig manure and compound fertilizer as basal fertilizer might promote the growth of Populus canadensis,but it had less fertilizer effect for abandoned farmlands and orchards.
