摘要
为了筛选出适宜陇东(高海拔、干旱)地区种植的高粱新品种,本研究通过引进 10 个粒用高粱品种在平凉地区进行种植,观察记录开花期、成熟期、穗形、穗型、壳色等农艺性状,对株高、茎粗、叶片数、产量、抗病性等进行分析.结果表明,吉杂 193、辽杂 68 和晋中 104 适宜在陇东地区进行大面积推广种植,产量分别为 541.30 kg/667 m2、524.26 kg/667 m2、508.52 kg/667 m2,晋糯粱 10 号、凤杂 88、辽糯梁 2 号、泉粱 5 号、本糯 5 号、沈杂 13 号、锦杂 118 等 7 个品种抗病性、抗倒性和株高不理想,引种价值不大,不建议引种.
Abstract
In order to screen out new sorghum varieties suitable for planting in Longdong region(high altitude,dry),this study introduced 10 grain sorghum varieties to plant in Pingliang,observed and recorded agronomic traits such as flowering,maturity,spike shape,ear type and shell color during the whole growth period,and analyzed plant height,stem diameter,leaf number,yield and disease resistance.The results showed that Jiza193,Liaoza68 and Jinzhong104 were suitable for large-scale cultivation in Longdong region,and the yield was 541.30kg/667 m2,524.26 kg/667 m2 and 508.52 kg/667 m2,respectively.Jinnuoliang10,Fengza88,Liaonuoliang2,Quanliang5,Benuo5,Shenza13 and Jinza118 were not the most ideal varieties for disease resistance,lodging resistance and plant height.
