摘  要:
研究了不同留茬高度和刈割次数对苏丹草生产性能的影响。结果表明:在生育期间,随着刈割次数的增加,鲜、干草产量均以刈割2次为最高,分别达到95.05和20.46 t/hm2;不同留茬高度处理的鲜、干草产量,以留茬8 cm处理最高,分别达105.11和37.64 t/hm2,高于或低于8 cm留茬高度处理的茎叶比和产草量均与其差异显著(P<0.05)。

摘  要:
The effects of different clipping frequencies and stubble height on the yield of Sorghum sudanense were tested.The results showed that the fresh and dry forage yield of two-time-clipping was the highest among the different clipping times;it reached 95.1 t/hm2 and 20.5 t/hm2 respectively.Stubble at 8 cm would obtain highest fresh and dry forage yield,it reached 98.3 t/hm2 and 14.8 t/hm2 respectively.
