2年试验结果表明,象草、南牧一号、杂交狼尾草、墨西哥类玉米、青贮玉米5种高禾草新植的当年鲜草每亩产量分别为13800、12963、12030、10911、7170kg,第二年的产量每亩分别为14848、14108、13280、10999、6850kg。叶茎比分别为南牧一号1:1.50、杂交狼尾草1:2.33、墨西哥类玉米1:2.39、象草1:2.63、青贮玉米1:3.35。5种牧草的营养品质和适口性依次为南牧一号、墨西哥类玉米、青贮玉米、杂交狼尾草、象草。5种牧草皆适宜在闽北栽培,其多年生的象草、南牧一号、杂交狼尾草皆能在保护措施下安全越冬。 The results of two years showed that the yield per mu of fresh grass in the year of newly planted five grass species of grassy weed, Nammu One, hybrid Pennisetum, Mexican corn and silage corn were 13800, 12963, 12030, 10911 and 7170kg respectively, The second year’s output was 14848,14108,13280,10999,6850kg per acre respectively. The ratio of leaf to stem was 1: 1.50 of Nanmu No.1, 1: 2.33 of hybrid Pennisetum, 1: 2.39 of Mexican corn, 1: 2.63 of Grass, 1: 3.63 of Silage, and 1: 3.35 of Silage, respectively. The nutritional quality and palatability of Nam Mu 1, Mexican corn, silage corn, hybrid Pennisetum, grassy. All five species of forages are suitable for cultivation in northern Fujian. The perennial grassy weeds, Nanmu No.1 and hybrid Pennisetum can both wintering safely under the protective measures.
