摘　　要：试验通过研究饲料玉米、桂牧一号、牛鞭草、黑麦草在湘西地区不同收割时期的产量以及总产量,以期缓解11月后养殖业草料短缺问题,并为后期研究牧草轮作提供依据。在试验地区,饲料玉米灌浆期产量为63.69 t·hm-2,全熟期产量57.5 t·hm-2;桂牧一号可收割5次,产量可达315.65 t·hm-2;牛鞭草可收割5次,产量达127.38 t·hm-2;黑麦草可收割5次,产量达110.82 t·hm-2。This experiment was conducted to study the yield and total yield of feed corn, Guimu-1 Hybrid Pennisetum urpureum, Hemarthria altissima, Lolium perenne in different harvesting periods in Xiangxi, in order to alleviate the shortage of forage in the breeding industry after November, provide the basis for the later research of forage rotation. The results showed that the yield of Feed corn was 63.69 t·hm-2 in the filling stage and 57.5 t·hm-2 in the mature stage, that of Guimu-1 Hybrid Pennisetum urpureum could be harvested five times a year, and 315.65 t·hm-2, that of Hemarthria altissima could be harvested five times a year, and 127.38 t·hm-2, and that of Lolium perenne could be harvested five times a year and 110.82 t·hm-2.
