摘要：目的在甘肃岷县茶埠乡2 300～2 800 m进行当归海拔效应研究,为探讨当归生态适应性奠定基础。方法采用田间试验和相关分析相结合的方法,探索海拔对当归产量形成的影响,明确影响产量的关键因子。结果当归产量随海拔升高而增加,中海拔和高海拔处理分别比低海拔处理高30.3%和22.0%,差异达显著水平(P<0.05);相关分析表明,温度(R2=0.745 3)和降雨量(R2=0.741 7)是影响当归产量的关键生态因子,丙二醛(MDA)(R2=0.911 8)和可溶性糖量(SS)(R2=0.883 1)是影响当归产量的关键生理生化因子,胞间CO2浓度(Ci)(R2=0.739 3)和净光合速率(Pn)(R2=0.733 2)是影响当归产量的关键光合特性因子。结论升高海拔、降低环境温度、增加降雨量和有效光辐射、降低植株体内MDA量、SS量和Ci均有利于提高当归产量。
Objective To explore the ecological adaptability of Angelic sinensis in altitude of 2 300—2 800 m in Chabu countryside,Min County,Gansu province.Methods Using the field experiment and correlation analysis,the effect of altitude on the yield formation was explored,and the key factors affecting yield were investgated.Results The yield of A.sinensis increased with the elevation rising,the yields in the mid-and high-altitudes were higher than that of low-altitude by 30.3% and 22.0%,with significant difference（P 0.05）;The correlation analysis showed that temperature（R^2 = 0.745 3） and rainfall（R^2 = 0.741 7） were the key ecological factors,the malonaldehyde（MDA,R^2 = 0.911 8） and soluble sugar（SS,R^2 = 0.8831） were the key physiological and biochemical factors,and the intercellular CO2（Ci,R^2 = 0.739 3） and photosynthetic rate（Pn,R^2 = 0.733 2） were the key photosynthetic characteristic factors influencing the yield of A.sinensis.Conclusion That is the benefit of the yield formation of A.sinensis by rising altitudes,reducing environmental temperature,increasing rainfall and photosynthetically active radiation,and reducing the contents of MDA,SS,and Ci.
