摘　　要：“绿源”牌生态有机肥对露地土壤特性及番茄生长和产量有一定影响,结果表明:施用生态有机肥2500kg/667m2～3750kg/667m2并追施适量化肥有利于生育期内各速效养分的平衡供应。施用生态有机肥有利于提高土壤有机质含量,降低土壤pH,防止土壤盐分积累;同时可明显增加番茄植株叶片数,但减小植株开展度,对株高、茎粗影响不大;施用生态有机肥2500kg/667m2～3750kg/667m2并配施适量化肥可使果实采收期提前1d～3d(天),同时明显增加单株采收果数和单株产量。The effects of“Lu Yuan”organic fertilizer（Ecological organic fertilizer）on soil characters, growth and yield of tomato were studied.The results were as follows：Applying the ecological organic fertilizer at a rate of 2 500 kg/667 m^2～3 750 kg/667 m^2 with proper inorganic fertilizer can keep every available nutrients balance during the whole growth stages. It was effective to promote organic matter of soil, lower pH, prevented from accumulation of salt. Applying this ecological organic fertilizer could obviously increase leaf numbers of tomato, but decrease plant expansion, and had little effect on plant height and stem diameter. Applying the ecological organic fertilizer at the rate of 2 500 kg/667 m^2～3 750 kg/667 m^2 with proper inorganic fertilizer could make the harvest time earlier for 1～3 days. and the fruit numbers per plant and production per plant be increased.
