Abstract: The effect of soil amendments on soil microbial communities,quality and yield of tomato in protected house were investigated for providing a scientific basis for reasonable use of soil amendments.A field experiment was initiated in a planting tomato greenhouse with different kinds of soil amendments(lime nitrogen,fosthiazate,abamectin and substrate).Changes of bacteria,fungi,quality,yield were monitored.Results showed that four different types of soil amendments could significantly increased the number of soil bacteria,fungi,actinomycetes and antagonists,while the numbers of bacteria and fungi in the later growing period of tomato compared with the middle growing period were decreased;the contents of lycopene and Vc reached the highest under substrate treatment for 8.75 mg/100g,78.60 mg/kg,respectively;the soluble sugar content ranged from 2.85% FW to 3.29% FW;compared with other treatments,the sugar acid ratio of CK,substrate and abamectin were 7.57,6.91 and 7.70,respectively,taste the best;under substrate treatment,the yield of tomato was the highest for 139 059.30 kg/ha,which was increased by 21.18% compared with CK.Considering the taste quality and yield,substrate could be used as a preliminary reference for tomatoes production.
