金沙江干热河谷恢复植被与造林技术研究

通过实验栽培与应用基础研究，筛选出赤桉、柠檬桉、绢毛相思、马占相思、大叶相思、新银合欢、木豆、山毛豆、车桑子及大翼豆等是适应干热生境和退化立地的造林树草种；营造的结构模式林具有改造环境、控制水土流失、培肥土壤和满足农民能源需求的多项功能；并对造林技术中的整地、育苗、造林时间等关键技术作了总结与研究，使造林保存率提高到８０％左右．该成果为干热河谷防护林建设提供了实用技术与科学依据

A STUDY ON VEGETATIONAL RESTORATION AND SILVICULTURAL TECHNIQUES IN THE DRY-HOT RIVER VALLEY OF THE JINSHAJIANG

E camadulensis,E cilriodora,A holoscricea,A mangium,A auriculif ormis,L leucocephala,C cajan,T candida,R wiscosa and M alroparpureus etc were selected as silvicultural trees and herbs of adaption to dry-hot environment and degenerative forest soil There were many functions in silvicultural structural patterns including environmental transformation,soil erosion control,ferti lity increase of soil and energy supply for farmers. Some key silvicultural techniques were studied and summarized for land preparation,seedling growth and silvicultural seasons etc. Silvicultural survival percent was around 80%. These techniques also provided practical skills and scientific basis for establishing protective forests of dry-hot river valley.
