| 摘 要： | 研究了施氮对不同刈割时期小黑麦中饲237 Triticale cereale cv. Zhongsi 237的饲草产量及营养成分的影响.结果表明:施氮和刈割时期对中饲237的草产量均有明显的影响,施氮可显著改善刈割后中饲237的再生性,促进植株生长,提高二茬鲜草、干草产量,且差异达极显著水平,同时可提高饲草的粗蛋白、粗脂肪、氨基酸含量,降低粗纤维含量,改善饲草品质.起身期刈割的处理,其二茬草的草产量、粗蛋白、粗脂肪产量均高于拔节期刈割的处理.追施氮肥处理的粗蛋白含量及产量均大于未追施氮肥的处理,而中性洗涤纤维、酸性洗涤纤维含量小于未追氮肥的处理.

| Abstract: | The effects of nitrogen topdressing on the yield and nutrition components of Triticale cereale cv.Zhongsi 237 were studied.The results showed that both clipping date and nitrogen topdressing shown obvious effects on the yield and regrowth.The growth,fresh yield,dry matter yield were significantly increased.Meanwhile,the contents of crude protein,crude fat and amino acid of young grass were increased;the content of crude fibre was reduced and the quality of the forage was improved.The yield of crude protein and crude fat of second clipping grass was higher than that clipped in jointing-period.The content and yield of crude protein under nitrogen treatments were higher than that of the control,and the contents of NDF and ADF were lower than that of the control. |
