【摘要】 以9个苦荞麦品种为材料,旨在筛选出适宜晋北地区种植的苦荞麦品种,并配套相适应的高产栽培技术措施,为荞麦生产和开发提供理论依据和技术指导。试验结果表明,黔苦3号、晋荞麦2号、黔苦5号产量居前3位,且生育期均为97 d,是适宜在晋北地区种植的中熟品种;川荞1号和西荞1号产量次之,生育期均为84 d,是适宜晋北地区种植的早熟品种;晋北地区无霜期较短,西荞2号和六苦2081生育期较长,在落早霜(2011年9月16日)时其籽粒成熟度还不到70%,造成产量减少,不适宜在晋北地区种植。更多还原

【Abstract】 Nine tartary buckwheat varieties were chosen to screen suitable varieties for planting in the northern Shanxi area matching with proper high yield cultivation techniques and measures for buckwheat production and development to provide the theory basis and the technical guidance.The test results showed that,the yield of Qianku 3,Jinqiaomai 2,Qianku 5 were in the top 3 places and the growth period(from seedling emergence to mature) was 97 d.Thus it was the suitable medium variety for planting in the northern Shanxi area followed by the yield of Chuanqiao 1 and Xiqiao 1 with the the growth period of 84 d,which were the suitable variety for planting in the northern Shanxi area;frost-free period was short in the northern Shanxi area and the growth periods of Xiqiao 2 and Liuku 2081 were longer.In the early frost on September 16,2011,the grain maturity was under 70% resulting in the yield diseasing,so it was not suitable for planting in the northern Shanxi area.更多还原
