【摘要】 研究了不同肥料对大棚番茄及其土壤的影响。结果表明:生物有机无机复混肥对番茄产量、品质和土壤养分有重要的作用。与NPK无机复混肥、常规施肥相比,生物有机无机复混肥可使番茄产量增加7 34%～13 64%,果实可溶性糖、有机酸、维生素C、糖酸比分别提高18 2%～23 2%、8 3%～15 6%、13 2%～15 1%、9 1%～12 6%,果实中硝酸盐(NO3-)含量下降22 9%～23 8%。土壤耕层有机质、碱解氮、速效磷、速效钾含量分别增加8 25%～10 48%、9 43%～14 71%、11 29%～15 00%、13 60%～18 34%。根际土壤中细菌、真菌、放线菌的数量依次增加45 45%～60 00%、14 29%～33 33%、44 19%～100 00%,细菌与真菌数量比值提高19 98%～37 27%。更多还原

【Abstract】 This paper described the influence of different fertilizers on tomato planted in protected soil . The results showed that biological organic-inorganic compound fertilizer expressed quite important effects on yield, quality of tomato and soil nutrient. Compared with the NPK chemical compound fertilizer and control, the yield, soluble sugar content, organic acid content, and VC content in tomato were increased 7.34%～13.64%, 18.2%～23.2%, 8.3%～15.6%, 13.2%～15.1% respectively , while the nitrate content of tomato were reduced 22.9%～23.8%. The content of organic matter, alkaline N, available P, available K in tested soil were increased by 8.25%～10.48%, 9.43%～14.71%, 11.29%～15.00%, 13.60%～18.34% respectively; the number of bacteria, actinomycetes, and fungi were increased by 45.45%～60.00%, 14.29%～33.33%, 44.19%～100.00%.更多还原
