摘　　要：通过大棚小区试验,研究在无机肥施用量相同情况下,增施菌渣有机肥对大白菜产量及品质的影响.结果表明：菌渣施用量达30t·hm^-2 时, 白菜产量、株高、叶绿素、维生素C、可溶性糖分别比对照提高43.5%、9.7%、26.7%、15.5%和21%;硝酸盐含量以对照最高,为1120mg·kg^-1,施用菌渣能使大白菜硝酸盐含量降低3.4%～24.2%.表明菌渣与无机肥混合施用,能显著降低硝酸盐在白菜体内的积累.In a greenhouse ,utilization of mushroom dregs for fertilizing Chinese cabbages was investigated .When the dregs were applied up to 30 t/hm2 ,the yield ,plant height and contents of chlorophyll ,vitamin C and soluble sugar of the cabbages increased 43.5% ,9.7% ,26.7% ,15.5% and 21% ,respectively ,as compared with control . The highest nitrate content in the cabbages was 1 ,120 mg/kg found in control .That was reduced by 3.4-24.2%with the dregs application .Consequently ,besides improvements on quality ,combining the mushroom dregs with regular inorganic fertilizers in the vegetable cultivation could significantly reduce the nitrate accumulated in the cabbages as well .
