摘　　要：以金鹏1号番茄为试材,采用随机区组设计设6个处理,研究了中等肥力土壤条件下,不同施肥水平对春大棚番茄产量及品质的影响,以期探讨施肥水平与大棚番茄产量与品质的关系,为设施栽培番茄提高产量,改善品质提供理论依据。结果表明:所有施肥水平中有2个处理达到目标产量,番茄产量和果实中可溶性固形物,Vc,可溶性糖,有机酸和硝酸盐含量均明显高于对照,并且随着施肥水平的提高而提高,但肥水过剩的条件下,番茄产量和品质又呈下降趋势。综合品质及产量2个因素,中等土壤肥力的塑料大棚番茄春季栽培中,推荐最佳施肥量大约每667m2施干牛粪7500kg,尿素125kg,过磷酸钙250kg,硫酸钾84kg。This experiment designed 6 treatments using Random Blocks, used j inpeng 1 tomato as the experiment material, effects of different fertilization levels on middle fertility land ranged, yieId and quality of tomato were studied. The study was done to evaluate the relationship between fertilization theoretical foundation for further research of increasing yield and level and the yield, quality in tomato, and to provide improving quality. It had 2 treatments reached the target yield in all fertilization level, tomato yield and content of Soluble matter, Vitamin C, soluble sugar, Organic acid, nitrate were obviously superior compared with the control. And all were remark increased by increasing the amount of fertilization levels. But the excessive fertilization made various index of tomato was downtrend. Considering the factors of both quality and yield, about dry cattle manure 7 500 kg/667m^2, carbamide 125 kg/667m^2, calcium superphosphate 250 kg/667m^2 and potassium sulphate 84 kg/667m^2 as the optimal fertilizer rate during spring season tomato cultivation in plastic greenhouse with medium soil fertility according to experiment.
