| 摘 要： | 通过覆盖地膜与未覆盖地膜栽培方法,进行墨西哥饲用玉米、皇竹草、高丹草等禾本科牧草品种对比试验,结果表明,覆盖地膜组比未覆盖地膜组试验生长季节内多刈割牧草1～2茬次,增加了牧草产量,墨西哥饲用玉米增产53.36%;皇竹草增产35.36%;高丹草增产23.68%,其中墨西哥饲用玉米产鲜草量高达180 945 kg/hm2.为沈阳地区选择禾本科牧草栽培模式,增加牧草产量,提高经济效益提供了依据.

| Abstract: | Comparison experiments was carried out among 3 varieties of Gramineae grasses including Euchlaena mexicana,Pennisetum hydridum and Pacesetter by film-mulching cultivation and non film-mulching cultivation.The results indicated that the groups of film-mulching cultivation were cradled more one to two stubble than non film-mulching cultivation groups in tested growing season.The yields of Euchlaena mexicana,Pennisetum hydridum and Pacesetter were in film-mulching groups higher 53.36%,35.36 and 23.68% than that in non film-mulching groups respectively and the fresh grass yields of Euchlaena mexicana were 180 945 kg/hm2.The tests provided a basis for selecting cultivation mode,increasing production and raising economic returns of Gramineae grasses in Shenyang region. |
