| 中文摘要: |
| 2000年木豆(Cajanus cajan(L.) Millspaugh)引入云南省元谋干热河谷地区,观测其物候特征、生长适应性、抗旱适应性、抗光热适应性等植物学指标,以了解其对干热退化山地的整体生态适应性。结果表明,木豆能适应干热河谷的退化山地生长环境,其生长势优于原产地,表现出明显的速生性;木豆的抗光热能力较强,能适应干热河谷的不同光照及高温环境,但温度高于37℃,则光合作用停止;木豆的抗旱能力较强,能够通过不同的生理适应性度过旱季,完成其生长周期。木豆适应于干热河谷的生态环境,利用价值较大,是干热河谷退化山地治理与开发的优选灌木。 |
| 英文摘要: |
| 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. |
