分析不同收割时期闽江口湿地互花米草的营养成分,确定最佳收获期,并探讨互花米草的饲用价值.结果表明,互花米草的最佳收获期是6～9月的营养生长期,在此期间的互花米草粗蛋白13.57％、粗脂肪3.04 ％、钙0.34％、磷0.18％、天冬氨酸1.37％、谷氨酸0.75％、中性洗涤纤维58.78％、酸性洗涤纤维34.47％、NaCl含量3.51％.互花米草不仅氨基酸组成成分齐全、含量丰富,饲料相对价值(RFV)达98.17％,与杂交狼尾草相近,具有一定的饲用价值.%This study was to determine the commercial value and optimum harvest time of the common cordgrass, Spartina alterni flora < collected from the wetland of Min River estuaries in Fujian. The analytical results indicated that the grass' nutritional value peaked between June and September in a year. During this period of time, its crude protein reached 11. 54%; calcium, 0.32%; phosphorus, 0. 16%; NDF, 58. 78%; ADF, 34. 47%; ash, 7.93%; and NaCl, 3. 35%. Consequently, S. alterni flora was found to be rich and complete in amino acids, and that it could be a potential source as forage.
