摘　　要：为进一步探明宽幅匀播与常规条播对青稞生长生理特性及产量的影响,以甘南州农业科学研究所自主选育“甘青9号”为供试品种,采用机械宽幅匀播与人工常规条播进行不同耕种方式对高原青稞生长、光合特性及产量形成的研究。结果表明:宽幅匀播可有效增加青稞穗长、穗粒质量及产量,优化青稞叶片光合特性,促进青稞产量增加,且宽幅匀播较常规条播增产14.29%,而常规条播叶绿素含量(soil and plant analyzer develotrnent,SPAD)整体略高于宽幅匀播。宽幅匀播优于常规条播,利于高原青稞种植生产。To further explore the effects of wide range uniform sowing and conventional strip sowing on the physiological characteristics and yield of highland barley,‘Ganqing 9’independently selected by Gannan Agricultural Science Research Institute as the test variety,different cultivation methods of mechanical wide range uniform sowing and artificial conventional strip sowing were performed and the growth,photosynthetic characteris-tics,and yield formation of highland barley were studied.The results showed that wide range uniform sowing can effectively increase the ear length,ear grain quality,and yield of highland barley,optimize the photosynthetic characteristics of highland barley leaves,promote the increase yield of highland barley,and increase the yield by 14.29%compared to conventional strip sowing.However,the SPAD of conventional strip sowing is slightly higher overall than that of wide uniform sowing.Wide uniform sowing is better than conventional drill sowing,which is beneficial for the cultivation and production of highland barley.
