摘　　要：按甘蔗梢与水葫芦的质量比3:7(C3W7)、5:5(C5W5)和7:3(C7W3)分别调制3种混合青贮,同时调制水葫芦单贮(W10)、甘蔗梢单贮(C10)作为对照,每个处理重复3次,常温下贮存60d,开封后测定青贮的pH、乳酸(LA)、乙酸(AA)、干物质回收率(DMR)、氨态氮(NH3-N)等。结果表明,随甘蔗梢比率升高,青贮的LA含量极显著增加,pH极显著降低(P<0.01)。同时,随甘蔗梢比率增加,3种混合青贮和C10单贮的AA含量和NH3-N极显著减少,DMR极显著上升(P<0.01)。可见,利用甘蔗梢能显著改善水葫芦青贮的品质,调制甘蔗梢水葫芦混合青贮是开发利用水葫芦的一条极佳途径。Cane stern and water hyacinth were ensiled at three different kinds of mixed ratio, which were 3：7,5：5and 7：3（short for C3W7, C5W5 and C7W3）,and an only water hyacinth silage（W10）, an only Cane stern silage（C10） as two controls, Each treatment was three repeats. Silages were fermented for 60 days under normal temperature. Then the pH value, Lactic acid（LA）, acetic acid（AA）, dry matter recovery（DMR）, ammonia（NH3-N）, and other items were measured. Results indicated that with the ratio of cane stern increased, lactic acid of silage（LA） was significantly increased, pH was significantly reduced（P0.01）. the content of three sorts of mixed ratio silages and an only cane stern silage of acetic acid （AA） and ammonia（NH3-N） have been significantly decreased with the increasing of cane stern, while the DMR has increased greatly（P0.01）. It will be seen that using of cane stern can significantly improve the quality of water hyacinth silage, modulating of mixture silage between cane stern and water hyacinth is a feasible way for development and utilization of water hyacinth.
