摘要
对川东北地区的扁穗雀麦、苇状羊茅、"广益"牛鞭草、"重高"牛鞭草等4种禾本科牧草的生长速度、产草量、叶宽和叶长等性状进行了研究。结果显示,4个材料都能适合该地区的气候和土壤条件,扁穗雀麦的生长速度最大,其次为"广益","重高"、苇状羊茅最小;另外,扁穗雀麦的叶片长度和宽度都显著高于其他材料;从产量上来看,"广益"最高,达26493.0kg/hm2,"重高"和扁穗雀麦次之,分别为26040.0和21103.5kg/hm2,苇状羊茅最低,为15768kg/hm2。由此表明,牛鞭草和扁穗雀麦均适宜在川东北丘陵地区栽培,具有较高的推广价值。
The applicability of 4 herbage grasses , including Bromus catharticus Vah, Festuca arundinacea Schreb, ＇ Guangyi＇Hemarthria compress,＇ Chonggao＇ H. compressa were compared in the study. The result showed that all materials could adapt in the soil condition and climate of the area. Among the 4 materials,the yield ofB. catharticu had the highest,reaching 26 493.0 kg/hm2 ,and that of Festuca. arundinacea was the lowest yield,being 15 768 kg/hm2. Therefore, B. catharticus and H. compressa were two kinds of quality gramineae that were suitable to the hill region of northeast of Sichuan.
