赤桉(EuCaIYPtus CamaIduhensls)在我省典型的金沙江干热河谷——渡口市,旱季长达八个月之久。蒸发量大于降雨量的三倍,相对湿度年平均55%的生态条件下,具有耐旱、耐瘠性强。生长极为迅速的优良特性,成为该市绿化造林的先锋树种。又因它对低湿亦有较强的适应性近年在盆地平坝,浅丘地区也有较大的发展。成为主要造林树种。为加速赤桉的发展,解决干形不甚通直问题,提高木材利用值价。我们在选优调查的基
Eucommia (EuCaIYPtus CamaIduhensls) in the province’s typical Jinsha River dry and hot valley - Ferry City, the dry season up to eight months. Evaporation is greater than three times the rainfall, the average relative humidity of 55% of the ecological conditions, with drought and barren strong. The rapid growth of the excellent features, become the city’s afforestation pioneer tree species. Because of its low humidity and also have a strong adaptability in recent years in the basin Pingba, shallow hill area also have greater development. Become the main afforestation species. In order to speed up the development of Eucalyptus grandis, it is necessary to solve the problem of not being dry and straightforward and to increase the value of timber utilization. We are in the selection of the best basis for the investigation
