岷江上游干旱河谷区岷江柏对不同海拔的响应
Effects of Different Altitudes on Growth Condition of Cupressus chengiana in the Arid River Valleys in the Upper Reaches of the Minjiang River
摘要
Abstract
Cupressus chengiana had been cultivated at different altitudes in arid valleys of the Minjiang River for 2 years.The soil moisture,plant physiology,biochemistry and growth were analyzed to explore the response of the main afforestation tree species to adversity in arid valleys and provide theory and technical guidance for the cultivation of Cupressus chengiana plantations in this area.The reseach results were as follows：with the increase of elevation,the photosynthetic rate,water use efficiency,the ativity of SOD,the content of MDA,soluble sugar and proline and the growth increment of Cupressus chengiana decreased firstly and then increased.While the transpiration rate and soluble protein increased firstly and then decreased.And the activity of POD and chlorophyll＇s content decreased with the increase of elevation.The results showd that the most suitable growth area of Cupressus chengiana in arid valleys of the Minjiang River was between 2 200 meter and 2 300 meter.Therefore Cupressus chengiana could widely planted in this area.关键词
