摘要
就7个多花黑麦草品种在达州浅丘地区的生产性能进行比较研究,比较分析各品种物候期、生长速度、产草量及茎叶比等性状。结果表明:长江2号(0. 625cm/d)和川农1号(0. 622cm/d)冬季生长速度相对较快,具有明显的冬季生长优势。总鲜草产量和总干草产量剑宝最高,长江2号和川农1号表现较好,各品种第3茬鲜草产量为主要产量。茎叶比最高的为长江2号,最低的为杰特。综合分析,剑宝、长江2号和川农1号在生长速度、产量、株高、分蘖数等性状上表现较好,适合在达州浅丘地区推广。
The production performance of 7 varieties of annual ryegrass was studied in the hilly area of Dazhou by phenological phase,growth rate,yield and stem leaf ratio.According to the research,the winter growth rates of Changjiang No.2(0.625cm/d)and Chuannong No.1(0.622cm/d)were faster.The fresh and dry yield of Jumbo were the highest,Changjiang No.2 and Chuannong No.1 also had advantages.The fresh yield of the third cutting time was the main yield among all the varieties.The stem leaf ratio of Changjiang No.2 was the lowest,and the highest one was Jivet.Therefore,Jumbo,Changjiang No.2 and Chuannong No.1 performed well in growth rate,yield,tillers and height,implying that they were more suitable for planting in the hilly area of Dazhou.
