福建南亚热带狼尾草属牧草品比试验

Test of forage varieties of Pennisetum Rich. in the south subtropics in Fujian

对狼尾草属的华南象草、细茎象草和杂交狼尾草3个牧草品种进行为期2a的比较试验.结果表明:在相同的田间管理,行株距为60cm×43cm的条件下,其鲜草平均产量分别为346.29、301.63和283.33t·hm-2;分蘖力最高的是杂交狼尾草,最低的是华南象草;其粗蛋白质量分数分别为8.75%、11.25%、10.55%.

Forage variety test was conducted to Pnnisetum purpureum Schumach cv.Huanan, thin stemmed P.purpureum and P.amcrieanum×P.purpureum in Fujian. Under the same field management condition and planting density (60 cm×43 cm), the average fresh grass yields were 346.29, 301.63 and 283.33 t·hm-2 respectively. The tillering ability was the highest in P.amcrieanum×P.purpureum and the lowest in P.purpureum Schumach.cv.Huanan. Sample analysis indicated that the crude protein contents were 8.75% in P.purpureum Schumach.cv.Huanan, 11.25% in thin stemmed P.purpureum, and 10.55% in P.amcrieanum×P.purpureum.
