摘要
【目的】评价藜麦在四川省阿坝州的农艺和品质性状,为该地区藜麦种植提供理论依据。【方法】将引进的9份藜麦品种/系试种于阿坝州马尔康市,调查分析全生育期、株高、主穗长、千粒质量、单株产量、产量、病虫害及籽粒蛋白质、脂肪、抗性淀粉和总淀粉含量。【结果】参试藜麦表现出一定的多样性,各材料间的千粒质量、单株产量、产量、蛋白质含量、脂肪含量和抗性淀粉含量均有显著或极显著差异(P<0.05或P<0.01)。参试藜麦早熟品种全生育期约125 d,晚熟品种全生育期159 d;株高(149.6±12.2) cm,穗长(52.5±6.8) cm,千粒质量(3.11±0.46) g,单株产量(62.5±33.2) g,产量(1 172.9±785.6) kg/hm~2;籽粒蛋白质含量(15.6±1.3)%,脂肪含量(6.4±0.5)%,抗性淀粉含量(0.15±0.02)%,总淀粉含量(55.9±1.9)%。病虫害有潜叶蝇、斜纹夜蛾和叶斑病,发生轻微。试种材料中NX-1和CX-2综合表现最好,可进一步推广种植。【结论】藜麦可在马尔康及生态条件类似的地区种植,但要注意选择品种、播期和病虫害观测,进一步引进和筛选适宜品种并形成配套栽培措施是下一步研究的重点。
[Purpose]To evaluate the agronomic and quality characteristics of quinoa in Aba Prefecture of Sichuan Province,and provide a theoretical basis for quinoa cultivation in this region.[Method]The duration,plant height,main spike length,1000-grain weight,yield per plant,yield,diseases and insect pests,protein,fat,resistant starch and total starch content of 9 quinoa accessions were investigated in Barkam.[Result]Quinoa accessions showed a certain diversity,and there were significant or extremely significant differences(P<0.05 or P<0.01)in 1000-grain weight,yield per plant,yield,protein content,fat content and resistant starch content among accessions.Growth durations was about 125 d in early-maturing accessions,and 159 d in late-maturing accessions.Plant height and inflorescence length was(149.6±12.2)cm and(52.5±6.8)cm,respectively.1000-grain weight was(3.11±0.46)g.Single plant yield and yield was(62.5±33.2)g and(1172.9±785.6)kg/hm2,respectively.Content of grain protein,fat,resistant starch and total starch were(15.6±1.3)%,(6.4±0.5)%,(0.15±0.02)%,and(55.9±1.9)%,correspondingly.There were slightly leaf miner,twill moth and leaf spot diseases been observed on quinoa accessions.NX-1 and CX-2 showed excellent performance among these accessions,which could be further cropped.[Conclusion]Quinoa could be planted in Barkam and areas with similar ecological conditions.Attention should be paid on the selection of varieties,sowing date and observation of diseases and insect pests.Introduction and screening of suitable varieties and formation cultivation measures were the focuses in the further.
