春播禾本科牧草品比试验

进行杂交苏丹草Sorghum sudanense,杂交狼尾草Pennisetum hybrid,美洲狼尾草Pennisetum americanum,饲用高粱Sorghum vulgare,墨西哥饲用玉米Euchlaena mexicana联5个春播禾本科牧草品种品比试验,结果表明:各品种均能适应试验地环境条件,试验期内未发生病虫害.其中以饲用高粱产草量最高,鲜草产量达到156 285kg/hm2,且草质好,适口性强,是继墨西哥饲用玉米后值得推广的优选品种.杂交狼尾草、美洲狼尾草不宜作高产栽培品种.试验为象山县丰富春播牧草栽培品种、推广常年牧草轮作模式、提高牧草生产效益提供了依据.

Variety comparative test of spring sowing forage species

Variety comparative tests have been carried out among 5 varieties of spring sowing forage grasses including Sorghum sudanense,Pennisetum hybrid,Pennisetum americanum,Sorghum vulgare,Euchlaena mexicana. The tests were located at Xiangshan county, Zhejiang province. The tests indicate that all the varieties could acclimate the environment in the testing area. There was no occurrence of plant disease and insect pests during the testing period. Among these varieties, Sorghum had the highest yield of 156,285 kg/ahm~2, as well as high quality and better palatability. Following Mexican forage maize, forage sorghum is another optimum variety for extension. Pennisetum hybrid and Pennisetum american are not suitable for planting as high-yielding varieties. The tests have provided a basis for enriching the varieties of spring sowing forage grass, extending the continuous forage grass rotation method and increasing the forage grass productivity in the testing area.
