Abstract:
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.
