摘　　要：针对桂林地区部分农户为追求苦瓜高产量,长期过量施用化肥,轻施有机肥,导致土壤养分结构失调、物理性状变差,造成产品品质降低,产收比扩大的现状,设计3个有机肥替代部分化肥处理,以期筛选出最佳的有机肥替代部分化肥的搭配。结果表明,车田河牌牛粪有机肥+EM菌发酵农家肥+复合肥(处理2)施肥方法最佳,在化肥减施情况下,产量达5078.2 kg/667 m^(2),比常规对照增产14.0%。In order to pursue high yield of bitter gourd,some farmers in Guilin area applied long-term excessive chemical fertilizers and light organic fertilizers,which led to imbalance of soil nutrient structure,deterioration of physical properties,in addition,reduced product quality and increased yield-to-income ratio.Three treatments were designed to replace some chemical fertilizers with organic fertilizers,in order to screen out the best combination of organic fertilizers to replace some chemical fertilizers.The results showed that Chetianhe brand cattle manure organic fertilizer+EM fermentation farm manure+compound fertilizer(treatment 2)was the best fertilization method.Under the condition of reducing chemical fertilizer application,the yield reached 5078.2 kg/667 m^(2),with an increase of 14.0% compared with the conventional treatment.
