| Abstract: |
| We introduced varieties of Cajanus cajan(L.) Millspaugh from India to the dry-hot valley of Yuanmou County,Yunnan Province in 2000.Its adaptability of phonological characteristic,growth condition at deteriorate mountain land and drought-heat resistance etc were studied.The results showed that Cajanus cajan(L.) Millspaugh could grow at degraded mountain land in the dry-hot valley,and its growth potential was better than original place.The light-heat resistance of Cajanus cajan(L.) Millspaugh are so strong that it could adapt the different light-heat environment in the dry-hot valley.But if the temperature was more than 37℃,it would stoped photosynthesis.The drought resistance of Cajanus cajan(L.) Millspaugh are also strong,and it could use different physiology modulation to adapt the dry-hot environment for completing its growth period. The Cajanus cajan(L.) Millspaugh could adapt the eco-environment of dry-hot valley.It is optimization shrub to control degraded mountain land. |
