Abstract: In order to improve the shortage of micronutrients in the facility soil, reduce the application of chemical fertilizers, increase the yield of tomatoes. In the sunlight greenhouse in Shuigaozhuang village(SFQ)and the sunlight greenhouse in Xiaoshawo village(XFQ), different amounts of organic fertilizers were used instead of chemical fertilizers as treatments to study the changes of available Fe, Mn, Cu content in the soil of facility greenhouses and relationship with tomato quality and yield. The results showed that the substitution of organic fertilizers for chemical fertilizers increased the content of available Fe, Mn and Cu in the soil to varying degrees. In the greenhouse SFQ, the available Mn and Cu contents in the SGY soil increased by 140.95% and 348.95% respectively compared with the control treatment; in the greenhouse XFQ, the XGY treatment significantly increased the soil available Fe content, which was 12.28% higher than the control treatment, the available Mn and Cu contents of XGY treatment were 84.60% and 215.71% higher than the control treatment, respectively. The available Fe, Mn, Cu in the two greenhouses were extremely significantly positively correlated with Vc and yield of tomato fruits, and were extremely significantly negatively correlated with the NO3--N content. Soil available Fe in the greenhouse SFQ and available Fe, Mn and Cu in soil in the greenhouse XFQ were all significantly correlated with yield. Replacement of chemical fertilizers with high amounts of organic fertilizers could extremely significantly increased the Vc content, reduced nitrate content of tomato fruits, and significantly increased tomato yield. Therefore, organic fertilizers can alleviate the shortage of micronutrients in the facility soil, which provide references for the sustainable utilization of soil and the development of facility agriculture.

Key words: Organic fertilizer replacement, Facility vegetables, Soil, Available Fe, Mn, Cu
