藜麦在张家口地区试种的表现与评价

本研究对在张家口地区进行试种的4份藜麦材料进行了农艺性状与品质性状评价。试种藜麦株高范围为119.27~180.51 cm,生育期范围为103~118 d。子粒饱满,产量可达3 637.32 kg/hm2,蛋白质含量为14.79±0.72%,脂肪含量为7.57±1.17%,天冬氨酸、赖氨酸和精氨酸含量分别为1.37±0.06%、1.00±0.03%、1.47±0.08%,皂苷含量为2.12±0.50%。以上结果与文献对比结果表明,藜麦富含多种营养成分,且蛋白质含量丰富、氨基酸比例平衡、增产潜力大等特点能够充分表现,适宜在张家口地区以及生态条件类似的地区种植。

Evaluation of Agronomic and Quality Characters of Quinoa Cultivated in Zhangjiakou

With agronomic and quality characters evaluated, four quinoa (Chenopodium quinoa willd) accessions were cultivated in Zhangjiakou, Hebei Province. Plant height ranged from 119.21 cm to 180.50 cm. Growth duration varied between 103 d and 118 d. The highest yield of the quinoa in Zhangjiakou reached 3637.32 kg hm-2. Contents of protein and oil were 14.79?.72% and 7.57?.17% respectively. Contents of aspartic acid, lysine and arginine were 1.37?.06%, 1.00?.03% and 1.47?.08% correspondingly. Saponin content was 2.12?.50%. These results demonstrate that trial planting of quinoa in Zhangjiakou is successful and could provide practical information for the promotion of quinoa in China.
