不同藜麦品种(系)在寒旱山区的种植表现

Cultivation Performace of Different Quinoa Varieties(Lines)in Cold and Arid Mountainous Area

为探明不同藜麦品种在寒旱山区的适应性与丰产性,筛选出适宜种植的优良藜麦品种。以陇藜1号、陇藜4号为对照,对引进的8个藜麦品种(系)在天祝县松山镇进行种植试验。结果表明,8个藜麦品种(系)均能成熟,折合产量为1529.02~3391.76 kg/hm^(2),其中LYLM-5折合产量最高,为3391.76 kg/hm^(2),较对照品种陇黎1号、陇黎4号分别增产13.79%、20.98%;青藜4号、蒙藜4号折合产量较高,分别为3313.53、3255.10 kg/hm^(2),较对照品种陇黎1号分别增产11.16%、9.20%,较对照品种陇黎4号分别增产18.19%、16.11%;黑藜1号、GSQ-9的农艺性状及产量表现最差。综合评价认为,LYLM-5、蒙藜4号适宜在天祝县松山镇范围内推广种植。

In order to explore the adaptability and yield potentials of different quinoa varieties in cold and arid mountainous areas and to screen out excellent quinoa varieties suitable for local planting,taking Longli 1 and Longli 4 as the controls,8 introduced quinoa varieties were used to conduct the cultivation experiment in Songshan Township,Tianzhu County.The results showed that 8 quinoa varieties(lines)could mature,and the average yield was from 1529.02 to 3391.76 kg/ha.Among them,LYLM-5 had the best average yield,i.e.,3391.76 kg/ha,which was 13.79%and 20.98%higher than that of Longli 1 and Longli 4,respectively.Yields of Qingli 4 and Mengli 4 were higher,which were 3313.53 and 3255.10 kg/ha,respectively,and were 11.16%and 9.20%higher that that of the control Longli 1,respectively,and were 18.19%and 16.11%higher that that of the control Longli 4,respectively.The agronomic traits and yields of Heili 1 and GSQ-9 were the worst.According to the comprehensive evaluation,LYLM-5 and Mengli 4 were suitable for planting in Songshan Township of Tianzhu County.
