Study on Selection of Acacia Species/Provenances in Water and Soil Serious Erosion Area

  • Received Date: 1994-12-27
  • After the introduction of aridity-tolerant acacias from Australia to Luokeng area where there are serious water and soil erosion,the face of the barren hill has been obviously changed and the water and soil erosion was preliminarily controlled.As for the result of 3 years'trial,there are 9 species and 19 provenances better than others,such as A. concurrens 17141,A. auriculiformis 16355,16147,16484,A. flavescens 15481,14968,14590,A. leptocarpa 16110,15478,A. colei 17906,17050,A. holosericea 16643,15732,A. crassicarpa 91000,A. ampliceps 14668 and A. brassii 17718,15480,16134. These species and provenances have good adaptability to poor site,fast growth and high biomass. In the first planting year they can close the crown,produce lot of litters to'cover the land and play an important role in the water and soil conservation.

Abstract: After the introduction of aridity-tolerant acacias from Australia to Luokeng area where there are serious water and soil erosion,the face of the barren hill has been obviously changed and the water and soil erosion was preliminarily controlled.As for the result of 3 years'trial,there are 9 species and 19 provenances better than others,such as A. concurrens 17141,A. auriculiformis 16355,16147,16484,A. flavescens 15481,14968,14590,A. leptocarpa 16110,15478,A. colei 17906,17050,A. holosericea 16643,15732,A. crassicarpa 91000,A. ampliceps 14668 and A. brassii 17718,15480,16134. These species and provenances have good adaptability to poor site,fast growth and high biomass. In the first planting year they can close the crown,produce lot of litters to'cover the land and play an important role in the water and soil conservation.
