摘　　要：对秋季大棚种植和露天种植的多花黑麦草进行周期刈割,研究刈割次数对江苏沿海大棚种植和露天种植多花黑麦草的产草量及品质的影响。结果表明,从刈割次数来看,大棚种植多花黑麦草以刈割5次产量最高,达85614.45 kg/hm^2,随着刈割次数的增加,粗蛋白含量下降,中性洗涤纤维含量和酸性洗涤纤维含量增加;从刈割时间来看,大棚种植的多花黑麦草鲜草产量在3月份左右达到峰值。Cyclic cutting of Lolium multiflorum planted in the greenhouse and the outdoor in autumn was carried out.The effects of cutting times on the yield and quality of L.multiflorum in the greenhouse and the outdoor in coastal areas of Jiangsu Province were studied.The results showed that,as for the cutting times,the yield of L.multiflorum in the greenhouse in the treatment with the cutting times of five times was the highest,reaching 85614.45 kg/hm 2.As the cutting times increased,the crude protein content decreased,the contents of neutral detergent fiber and acid detergent fiber increased.As for the cutting time,the fresh yield of L.multiflorum i n the greenhouse in March reached the peak value,showing a parabolic trend.
