摘要：

以"京欣2号"大棚西瓜为试材,研究了生物有机肥对大棚西瓜生长特性及品质的影响。结果表明:从幼苗期到膨瓜期,生物有机肥(BOF)和对照(CK)处理下西瓜株高、茎粗、主根长随生长期呈逐渐增加趋势,而叶面积指数在膨瓜期有所降低,不同时期BOF西瓜株高、茎粗、主根长叶面积指数均高于对照;BOF和CK处理下叶绿素a和叶绿素b含量均随生长期增加呈先增加后降低趋势,可溶性糖和可溶性蛋白质含量表现为逐渐增加趋势,不同时期BOF处理下西瓜叶片叶绿素a、叶绿素b、可溶性糖和可溶性蛋白质含量均高于对照;生物有机肥增加了大棚西瓜根区土壤养分,BOF处理下西瓜根区土壤有机碳、全氮和全钾含量均显著高于CK(P<0.05),其中,以有机碳的增加幅度最大(73.67%),对全磷的影响不显著(P>0.05);生物有机肥显著增加了大棚西瓜的单瓜质量和产量(P<0.05),并且增加了西瓜果实中维生素C、可溶性蛋白质、可溶性总糖、总酸度、总黄酮、中心糖、边糖含量和含水量,以可溶性糖的增加幅度最大。综合比较来看,生物有机肥可有效促进西瓜营养代谢协调均衡,还可以提高糖分含量,改善西瓜品质,确保西瓜的高产优质。
