摘　　要：为探讨日光温室栽培番茄化肥减量施用技术,通过有机复混肥替代化肥减施不同比例氮,研究其对日光温室番茄植株生长、果实品质、产量、土壤酶活性、土壤微生物数量等各项指标的影响。结果表明,与对照CK(鸡粪2000 kg·667 m^-2+常规化肥量333 kg·667 m^-2)相比,有机复混肥替代化肥的减氮施肥处理可不同程度地促进番茄生长,增加产量,改善土壤环境。其中T3(鸡粪2000 kg·667 m^-2+有机复混肥46.88 kg·667 m^-2+化肥283 kg·667 m^-2)处理,即有机复混肥替代减施氮含量15%的化肥,效果显著,番茄植株生长状况最好,产量品质最佳。In order to explore the technology of reducing fertilizer application in tomato cultivation in solar greenhouse,the effects of organic compound fertilizer alternative to chemical fertilizer to reduce different proportions of nitrogen on plant growth,fruit quality,yield,soil enzyme activity and soil microbial quantity of tomato in solar greenhouse were studied.The results showed that,compared with CK(Chicken manure 2000 kg·667 m^-2+conventional fertilizer amount 333 kg·667 m^-2),different fertilization treatments of organic compound fertilizer alternative to fertilizer nitrogen reduction all promoted tomato growth,increased yield and improved soil environment to varying degrees.Among them,T3 treatment(Chicken manure 2000 kg·667 m^-2+organic compound fertilizer 46.88 kg·667 m^-2+fertilizer 283 kg·667 m^-2),that is,organic compound fertilizer replaces fertilizer with reduced nitrogen content of 15%has a significant effect,with the best growth condition and the best yield and quality in the cultivation which the total soluble sugar content is 2.623%,the vitamin C content is 12.687 mg·100 g^-1,the soluble protein content is 20.917μ·g^-1,and the yield per 667 m2 is 17142.22 kg.
