甘引1号黑麦在高寒地区的适应性评价

通过甘引1号黑麦(Secale cereal cv.Ganyin No.1)在高寒地区适应性栽培试验,以冬牧70(Secale cereale cv.Wintergrazing 70)和固原小黑麦(Triticale Wittmack cv.Guyuan)为对照,对其在高寒地区的生产性能及营养价值做出客观评价。结果表明:甘引1号黑麦较冬牧70和固原小黑麦提前出苗4~6d;在抽穗期前甘引1号黑麦生长速度最快,生长速度2.20cm/d,孕穗期及孕穗期前刈割,一年可收获2茬;甘引1号黑麦的鲜草和干草产量均显著(P0.05)高于冬牧70黑麦和固原小黑麦,干草产量较后两者分别提高53.61%和41.39%,鲜草产量分别提高33.33%和27.45%;甘引1号黑麦粗蛋白、粗脂肪、钙、磷产量分别较固原小黑麦高42.36%、39.0%、54.02%和47.82%,较冬牧70高54.66%、53.61%、61.55%、60.59%。

Evaluation of the adaptability of Secale cereal cv. Ganyin No.1 in alpine areas

A experiment in Ganyin No.1 rye (Secale cereal cv.Ganyin No.1)cultivation was conducted in the alpine area,using Dounmu70 rye (Secale cereale cv.Wentergrazing70)and Guyuan triticale (Triticale Witt-mack cv.Guyuan)as controls.Productivities and nutritive values were assessed in this paper.The results showed that seeding stage of Ganyin No.1 was 4-6 days earlier than that of Dongmu70 and Guyuan.The growth rate (2.20 cm/d)of Ganyin No.1 was the fastest among the three varieties before heading stage.Ganyin No.1 could be harvested twice in a year as cutting at or before booting stage.The fodder yield and fresh fodder yield of Ganyin No.1 were significantly higher than those of Dongmu70 and Guyuan.The fresh fodder yield and fod-der yield of Ganyin No.1 increased by 33.33％ and 53.61％,respectively,compared with Dongmu70.The fresh fodder yield and fodder yield of Ganyin No.1 increased by 27.45％ and 41.39％,respectively,compared with Guyuan.The content of crude protein,crude fat,calcium and phosphorus of Ganyin No.1 increased by 42.36％, 39.0％,54.02％ and 47.82％,respectively,compared with Guyuan.Those values of Ganyin No.1 increased by 54.66％,53.61％,61.55％ and 60.59％,respectively,compared with Dongmu70.
