摘　　要：沼液肥含有丰富的有机质、微量养分、碱性磷酸酶、酶和有益微生物,是一种优质高效、无污染的有机肥料。设施番茄在长期传统施肥模式下,病虫危害愈发严重,鉴于此,本研究在番茄传统种植的基础上,进行了沼液肥与复合肥及农家肥的对比试验,得出施用沼液肥的处理增产61.8%,加倍沼液肥增产35.8%,复合肥增产20.7%,农家肥增产18.7%;加倍沼液肥处理的土壤有机质含量为41.14 g/kg,为所有处理中最高的,其对土壤pH的调节幅度也最大;且沼液肥处理还可以使土壤碱解氮、有效磷及速效钾分别提高1.63倍、12.66倍及76.30倍。Biogas slurry fertilizer is rich in organic matter,trace nutrients,alkaline phosphatase,enzymes and beneficial microorganisms.It is a high-quality,efficient and pollution-free organic fertilizer.Under the long-term traditional fertilization mode,the harm of plant diseases and insect pests is becoming more and more serious.In view of this,based on the traditional planting of tomato,this study carried out the comparative experiment of biogas slurry fertilizer,compound fertilizer and farm fertilizer.It was concluded that the treatment with biogas liquid fertilizer increased the yield by 61.8%,double the biogas liquid fertilizer by 35.8%,compound fertilizer by 20.7%and farmyard fertilizer by 18.7%.The soil organic matter content of double biogas liquid fertilizer treatment was 41.14 g/kg,which was the highest among all treatments,and its regulation range of soil pH was also the largest.Biogas slurry fertilizer treatment increased soil alkali hydrolyzable nitrogen,available phosphorus and available potassium by 1.63 times,12.66 times and 76.30 times respectively.
