摘　　要：研究不同有机碳(α-酮戊二酸、丙酮酸、草酰乙酸)的几种组合以及其与氮源配合施用对玉米、蔬菜生物量的影响。结果表明,喷施有机碳对玉米、蔬菜有较大的增产作用,其中组合碳优于单一碳,多碳源组合并配合氮源的效果最好,与清水对照相比,玉米增产超过10%,空心菜增产超过70%,苋菜增产60%。有机碳肥养分组合具有很大的增产潜力,是平衡施肥水平提升的新技术空间,值得深入研究。The effects of several combinations of different organic carbons(keto acid, pyruvic acid, oxaloacetate)and their combined application with nitrogen sources on the biomass of corn and vegetables are studied. The results show that spraying organic carbon on corn and vegetables has a great effect on increasing yield. Among them, the combined carbon is better than the single carbon, and the combination of the multiple carbon sources and the nitrogen source has the best effect. Compared with spraying water treatment, the yield of corn is increased by more than 10%, the yield of hollow cabbage is increased by more than 70%, the yield of amaranth is increased 60%. The nutrient combination of organic carbon fertilizer has great potential for high yield. There is a new technology space for better balanced fertilization, and worthy of further study.
