减施化肥配施微生物菌剂对番茄产质量和土壤肥力的影响

试验以樱桃番茄为材料,研究减施化肥配施不同微生物菌剂(EM和春语)对樱桃番茄产量、品质和土壤肥力的影响。结果表明:减施化肥配施EM菌剂处理(RCF+EM)的樱桃番茄产量高于全量化肥处理(CF),但差异未达显著水平(P0.05),RCF+EM处理番茄可溶性固形物、可溶性蛋白和可溶性糖含量显著高于CF处理(P0.05),增幅依次为31.05%、27.82%、62.73%;RCF+EM处理的土壤pH、有机质、速效养分和微生物生物量碳氮含量均高于CF处理,其中p H、碱解氮和微生物生物量碳差异达到显著水平(P0.05),增幅依次为13.07%、20.83%、66.10%。与EM菌剂相比,春语微生物菌剂的效果总体较差。因此,减施化肥配施EM菌剂可提高樱桃番茄产量和果实品质,对土壤肥力也有良好的改善作用。

Effects of Reduction of Chemical Fertilizer Combined with Application of Microbial Agents on Growth and Soil Fertility of Cherry Tomato

This research examined the effects of the reduction of chemical fertilizer (RCF) combined with the application of microbial agents (EM and CY agents) on the yield and quality of cherry tomato and on soil properties. The results showed that the contents of soluble solids, protein and sugar under RCF + EM treatment were significantly greater than those under the CF treatment (31.05%, 27.82% and 62.73% higher, respectively, P<0.05). There was no significant difference in the yields between RCF + EM and CF treatments (P>0.05). Soil pH, contents of organic matter and available nutrients and microbial quantity under RCF + EM treatment were higher than those under CF treatment, among of which, soil pH, contents of available nitrogen and soil microbial biomass nitrogen were significantly higher (13.07%, 20.83% and 66.10% higher, respectively, P<0.05). Comparatively, the effects of RCF + EM treatment on cherry tomato were generally better than those of RCF + CY treatment. In conclusion, reduction of chemical fertilizer combined with the application of EM agents can not only promote the yield and quality of cherry tomato, but also improve soil fertility.
