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.
