陇中旱作区藜麦引种比较试验初报

为筛选出适宜会宁县旱作区种植的藜麦品种,促进藜麦产业的发展。以藜麦新品种陇藜2号为对照品种,对引进的10个藜麦品种(系)在会宁旱作区进行比较试验。结果表明,在当地旱作区栽培条件下,参试藜麦品种(系)均能正常成熟,折合产量为2 341.7～3 091.7 kg/hm2,其中以18-19的折合产量最高,为3 091.7 kg/hm2,较对照品种陇藜2号增产13.80%;其次是YY32,折合产量为3 008.3 kg/hm2,较对照品种陇藜2号增产10.73%。这2个品系综合性状表现优异,株高适中,果穗紧凑,单株重量较大,增产潜力较大。综合考虑会宁旱作区的生产需要,认为18-19和YY32适宜在会宁县旱作区种植。

Preliminary Report on the Comparison Experiment of Quinoa Varieties Introduction in Central Gansu

To select quinoa varieties suitable for the dry farming pratice at Huining County and to promote the development of quinoa industry. A comparision experiment was conducted at Huining County using 10 introduced quinoa varieties(lines) and Longli 2 (control). Results showed that all the introduced quinoa varieties (lines) could reach their maturity under dry farming practice locally with average yields varied between 2 341.7 to 3 091.7 kg/ha, among which the average yield of 18-19 was the highest, i.e. 3 091.7 kg/ha, and was 13.80% higher compared with that of control Longli 2, average yield of YY32 ranked the second with a number of 3 008.3 kg/ha and was 10.73% higher compared with that of control Longli 2. Those 2 varieties showed ideal comprehensive characters, suitable plant heights, compact ears and heavy individual weights, and were considered as varieties with high yield potentials. Taken the production requirement of dry farming at Huining, 18-19 and YY32 are suitable for Huining under dry farming practice.
