摘　　要：目的:研究栽培模式对丹参光合作用及其产量的影响。方法:试验设覆地膜双垄、无地膜双垄和传统单垄3种栽培模式。使用LI-6400XT光合仪测定不同生育期丹参叶片的光合参数;并测量地上部分和地下部分生物量。结果:不同栽培模式下,丹参叶片气孔导度由大到小依次是覆地膜双垄>无地膜双垄>传统单垄;胞间CO_2浓度由大到小依次是无地膜双垄>覆地膜双垄>传统单垄;蒸腾速率由大到小依次是覆地膜双垄>无地膜双垄>传统单垄;净光合速率由大到小依次是覆地膜双垄>无地膜双垄>传统单垄。丹参地下部分鲜重和干重由大到小依次是覆地膜双垄>无地膜双垄>传统单垄,覆地膜双垄较无地膜双垄和传统单垄分别提高16.62%、18.20%和14.68%、48.62%。结论:地膜栽培模式通过提高土壤的含水量来降低水分胁迫,从而提高了丹参的光合效率,使其积累更多的干物质,最终达到提高药材产量的目的。Objective：To investigate the effect of cultivation pattern on photosynthesis and yield of Salvia miltiorrhiza. Methods： The covering plastic mulch,the uncorering plastic mulch,and the trditional cultivation pattern were used to analysed. LI-6400XT photosynthesis was used to determine the photosynthetic parameter of Salvia miltiorrhiza, and some growth indexes of Salvia militiorrhiza were measured,and the accumulation was measured. Results：The change of stomatal conductance in the plants of different treatments were as follows,the covering plastic mulch 〉 the uncovering plastic mulch 〉 the traditional cultivation pattern;the change of intercellular CO2 concentrationin the plants of different treatments was as follows, the uncovering plastic mulch 〉 the covering plastic mulch 〉 the Iradi- tional cultivation pattern;the change of transpiration rates in the plants of different treatments was as follows,the covering plastic mulch 〉 the uncovering plastic mulch 〉 the traditional cultivation pattern;the change of net photosynthetic rates in the plants of different treal- ments was as follows,the covering plastic mulch 〉 the uncovering plastic mulch 〉 the traditional cultivation pattern. The change of fresh and dry weight in root of Salvia miltiorrhiza of different treatments was as follows,the covering plastic mulch 〉 tile uncovering plastic mulch 〉 the traditional cultivation pattern. Compared to the uncovering plastic mulch and the traditional cultivation pattern ,the fresh and dry weight in the root nf Salvia miltiorrhiza of the covering plastic mulch were increased to 16. 62% , 18.20% and 14. 68% ,48.62% Conclusion：The cultivation pattern of covering plastic muleh reduced water stress by increasing the water content of soil to increase photosynthesis efficiency,thus increase the yield of Salvia miltiorrhiza.
