摘　　要：为了解青稞新品种昆仑13号的产量影响因素,本试验以昆仑13号为材料,研究了在三类不同生态区的肥料和密度试验对其产量、田间群体密度和产量性状的影响。结果表明,3个生态区肥料和密度试验表明生态环境对昆仑13号产量的影响较大,昆仑13号在3个生态区的平均产量变幅为3 148-6 510 kg/hm2,生态环境和播种量对昆仑13号田间群体密度产生直接和重要的影响。试验给出了昆仑13号在3个生态区达到目标产量需要施入尿素、磷酸二铵和播量的最优实施方案.这些栽培措施组合和不同生态区高产分析建议可以作为昆仑13号青稞新品种在青海省青稞主产区大面积推广种植的高产栽培措施优化方案。In order to study the influencing factors on the yield of Kunlun 13, 3 different ecological zones were selected to conduct fertilizer and density tests to study the yield, density and yield traits of Kunlun 13. 3 ecological fertilizer and density tests showed that the ecological environment had big influence on Kunlun 13, the average yields in 3 zones ranged from 3 148~6 510 kg/hm2, ecological environment and the seeding amount had direct and important impact on the field density of Kunlun 13. Experiment showed optimal plan of urea, phosphoric acid diamine and seeding amount of Kunlun 13. These cultivations and high-yield suggestions on different eco-regions suggested that Kunlun 13 could be spreaded and planted in Qinghai.
