摘 要:
经对杂交柳水湿地区适生性研究表明，杂交柳有比杨树更强的耐水湿能力。初步认为洞庭湖地区适宜推广杂交柳的水湿地有：水淹时间每年240d（一次连续3个月以内）、林分或接近没项不超过120d（一次连续43d）的湖洲滩地；季节性水淹河洲及岸边洼地；内垸低湿地。季节性水淹对杂交柳的生长是有利的，淹水100～240d（一次连续3个月以内）的湖洲滩地最适宜杂交柳造林。常年积水的洼地不适宜杂交柳造林。[著者文摘]

Abstract:
The result of examination on the adaptability of hybrid Willow in water-wet area showed that： The water resistance ability of hybrid Willow was higher than it of Poplar. The suitable afforest hybrid Willow water-wet area in Dongting Lake area were chosen preliminary in following： The beaches of lake which water-flooded time less than 240 days a year （ the continued time less than three months）, and the stand or water-flooded closed to tbe top less than 120 days （the continued time less than 43 days） i the seasonal water-flooded beach of river and the depression of bank; the low water-wet area in inner embankment area. The Seasonal water-flooded was favorable for growth of hybrid Willow, the best beach of lake for afforest Willow was water-flooded from 100 to 240 days （the continued less than tree months）. The depression was not suitable for afforest Willow which was water-flooded whole year.[著者文摘]
