摘　　要：试验设:Ⅰ70 mL菌肥/5L(水)、:Ⅱ100 mL菌肥/5L(水)、Ⅲ:200 mL菌肥/5L(水)3个浓度、Ⅳ:化肥(尿素)(250 g/株)、Ⅴ:对照(除底肥以外不施任何肥料)5个处理,探讨菌肥在枣树上的应用效果,通过田间施用菌肥,研究菌肥对大铃枣光合特性和产量品质的影响。结果表明:施用菌肥可改善大铃铛枣叶片的光合特性,施用菌肥提高了枣叶片气孔导度与净光合速率,可改善大铃铛枣的口味和提高大铃铛枣的产量和品质。以70 mL(Bacterial Manure)/5L(H2O)处理效果最好,比Ⅴ(对照)、Ⅳ(化肥)分别增产35.41%和10.52%;施用菌肥后的大枣的糖酸比变化比较大,以70 mL(Bacterial Manure)/5L(H2O)处理效果最好,达到了36.4%;Vc含量比Ⅴ、Ⅳ分别提高37%和52%。Effects of Bacterial Manure on the photosynthetic properties,yield and quality of Chinese date were studied in field experiment in 2007. Our test designed as followling I： 70 mL bacterial manure per 5 L（water）,Ⅱ：100 mL bacterial manure per 5 L（water）,Ⅲ：200 mL bacterial manure per 5 L（water）, Ⅳ： chemical fertilizer（urea）（250 g per strain）, V： CK（without any fertilizer except base fertilizer）. The results showed that applying Bacterial Manure could improve the photosynthetic properties, increased the yield and improve the quality of Chinese date, and increased Chinese date conductance and transpiration rate of Chinese date leaves. The application of Bacterial Manure under the condition of 70 mL （Bacterial Manure）/SL（H2O）decrement of the routine rate had yield increments about 35.41% and 10.52% compared with the control and carbamide application respectively. Using Bacterial Manure had big election sugar-acid ratio of fruit. The eapplication of Bacterial Manure under the condition of 70 mL （Bacterial Manure）/5L（H2O）decrement of the routine rate had best effects and could increase Vitamin C content significantly.
