| 摘 要： | 采用农户问卷调查、田间取样及实验室化验分析方法,分析了福州市郊11片蔬菜基地的蔬菜施肥现状及菜地土壤养分累积特征,结果表明:(1)蔬菜生产上以施用化肥为主,有机肥为辅,化肥以俄罗斯进口复合肥最为普遍;每茬不同类型蔬菜的平均施肥水平(N、P2O5和K2O总养分)在493.6-1212.2 kg.hm-2之间,氮磷钾比例(平均1∶0.77∶0.75)不协调,磷肥施用量明显偏高;各轮作类型蔬菜平均施肥量(N、P2O5和K2O总养分)在2002.3-3455.2 kg.hm-2.a-1之间.(2)与林坡地自然土壤相比,菜地土壤的全磷(2.04 g.kg-1)、速效磷(182.9 mg.kg-1)、CaCl2-P(1.02 mg.kg-1)平均含量呈现明显累积,分别提高3.16、6.87和12.3倍;有机质(37.4 g.kg-1)和全氮(2.18 g.kg-1)平均含量分别提高33.43%和17.16%;全钾含量变化不明显;而碱解氮(200 mg.kg-1)、速效钾(243.8 mg.kg-1)、CEC(14.7 cmol.kg-1)和pH值(5.97)分别降低了15.01%、38.2%、3.14%和9.7%. |

| Abstract: | With the method of questionnaire investigation to farmers,sampling from field and assay at laboratory,fertilization status quo and nutrient accumulation of 11 pieces of vegetable field in the suburb of Fuzhou city were analyzed.Results showed that:(1) Chemical fertilizer was primarily used,organic fertilizer was complementarily used,in which the imported compound fertilizer made in Russia was applied most prevalently.The average fertilization rate(including N,P2O5 and K2O) of different kinds of vegetable wa... |
