Effects of Afforestation for Poplar with Different Methods
Land suitable for poplar afforestation types were investigated by adopting different species ,different affor-estation methods in Chaoyang City .Result shows that :afforestation method of pit-filling with the foreign soil is far superior than that with the original soil ;afforestation effect of Populus × xiaozhuanied cv .‘Jinxian’ on overflow land with thin soil layer is optimal than that of Populus liaoningensis ;afforestation effect of Populus liaoningensis& Populus× euramerlicana‘Guariento’ on overflow land with thick soil layer is optimal than that of Populus× xi-aozhuanied cv .‘Jinxian’ ;the survival rate & preservation rate of plantation plots by using deeply rooted method on overflow land with deep-water are higher ;trees grow well ,much higher than that with conventional planting meth-od;overflow land with shallow-water (or thawing-flooded subsurface soil) can effectively prevent flooding or pro-longed immersion by earthen mound planting ;tree can grow normally after planting ;on overflow land which is easi-ly-hit by floods ,the direction of flow for water being V-shaped ,the poplar stand which was established by fixed-pit deep-planting method can effectively prevent the rushing attack & hazards of flood ;the preservation rate by using the above method is more higher than that of the poplar which were rectangular with the main river channel .
