摘要
通过研究小黑麦(×Triticosecale Wittmack)新品系(P_2、P_4)在甘肃省高寒牧区(肃南、合作、玛曲)的草产量及营养价值,以筛选适宜种植区域,以石大1号和中饲1048为对照品种。结果表明,不同试点间、小黑麦材料间和材料×试点交互作用间的草产量和营养价值均有显著差异(P<0.05)。4个小黑麦材料在3个试点的干草产量表现为P_2(14.42t·hm^(-2))>P_4(11.72 t·hm^(-2))>中饲1048小黑麦(10.03 t·hm^(-2))>石大1号小黑麦(9.70 t·hm^(-2)),粗蛋白总含量为P_2(13.31%)>P_4(12.17%)>中饲1048小黑麦(8.37%)>石大1号小黑麦(7.40%),中性洗剂纤维总含量为P_2(61.65%)<中饲1048小黑麦(63.82%)<P_4(64.89%)<石大1号小黑麦(68.14%),酸性洗剂纤维总含量为P_2(41.97%)<中饲1048小黑麦(42.15%)<P_4(43.35%)<石大1号小黑麦(45.06%)。综合分析,小黑麦新品系P_2高产优质,最适宜在甘肃省高寒牧区种植。
In order to screen the suitable area for new triticale lines( P_2,P_4),the hay yield and nutrition were studied in the alpine pastoral areas( Sunan,Hezuo and Maqu) of Gansu province,with Shida No. 1 and Zhongsi 1048 as control. The results showed that significant differences existedin triticale materials,experimental sites and the interaction between triticale materials and experimental sites(P〈0. 05). The averaged hay yield: P_2( 14. 42 t·ha^(-1)) P_4( 11.72 t·ha^(-1)) Zhongsi 1048( 10. 03 t·ha^(-1)) Shida No. 1( 9. 70 t·ha^(-1)),CP content: P_2( 13. 31%) P_4( 12.17%) Zhongsi 1048( 8. 37%) Shida No. 1( 7. 40%),NDF content: P_2( 61. 65%) Zhongsi 1048( 63. 82%) P_4( 64. 89%) Shida No. 1( 68. 14 %),ADF content: P_2( 41. 97%) Zhongsi 1048( 42. 15%) P_4( 43. 35%) Shida No. 1( 45. 06%). By comprehensive evaluation,the triticale new line P_2 was the best with high yield and good quality and was suitable to be planted in alpine pastoral areas of Gansu Province.
