几种多年生禾本科牧草栽培比较试验

Study on Comparative Cultivation of Perennial Forage Grasses

以5份禾本科牧草为试材,综合评定了各牧草品种的生育期、农艺性状和产量性状等方面,以筛选出适合哈尔滨地区种植的优良禾本科牧草品种。结果表明:供试的5个牧草品种均可在哈尔滨地区进行生产和开发利用。"农菁7号"偃麦草和"农菁6号"无芒雀麦综合性状表现最好,鲜草产量高、叶量丰富、营养价值高,是饲喂家畜和建立优质人工草地的理想禾本科草种;"农菁3号"鹅观草出苗率高,品质较好,应与豆科牧草混播建植人工草地进行放牧利用;"农菁11号"羊草和"农菁16号"披碱草干鲜比和干草产量较高,利于刈割后调制干草。

Taking five kinds of forage grass as test materials,the phenological phase,agronomic characteristics and yield of five forage grasses varieties were compared and studied,in order to breeding excellent forage grasses varieties that could adapt for planting in Harbin area.The results showed that according to the comprehensive evaluation,the five forage grasses could be planted and utilized in Harbin.Elytrigia repens Nevski of‘Nongjing No.7＇and Bromus inermis cv.of‘Nongjing No.6＇had a higher fresh grass yield and quantity of leaf and nutrition also higher than the other three grasses.These two grasses were suitable for feeding livestock and establish artificial grassland.Roegneria C.Koch.of‘Nongjing No.3＇had the highest germination rate and it＇s quality higher than the other grasses.Roegneria C.Koch.of‘Nongjing No.3＇should mixed sowing with legume forage to establish artificial grassland for grazing.Leymus chinensis Trin Tzvel of‘Nongjing No.11＇and Elymus L.of‘Nongjing No.16＇had the higher ratio of dry to fresh weight and dry grass yield,which suitable for harvest dry grass.
