摘要
在西宁首次引种了５个籽粒苋品种。６年试验结果表明，西宁生态条件下籽粒苋生育期平均１５０ｄ；种子萌发最低温度８～１０℃；出苗后５０ｄ生长速度加快。在西宁冷凉秋季能够正常灌浆成熟。但播种期提早，生育期则延缓。具有叶面积系数小，干物质生产日积累量小。
Five varieties of the grain amaranth (Amaranthus SPP.) known as 'future grain crop of mankind' were first introduced to Xining. Results of the test with six years indicated that the mean growth duration of grain amaranth were 150 days under the Xining ecological condition. The lowest germination temperature were 8￣10℃. The growth velocity were speed after 50 days of seedling. The filling and maturity of these varieties were normal in cool autumn of Xining. Their growth characteristics were as follows: less leaf area index, less accumulation amount per day, lower accumulation peak value and shorter period of peak value. These indicated that the grain amaranth had the adaptability to ecology conditions of the high and cold area.
