摘　　要：将8种物质苜蓿汁、韭菜汁、木醋液、白菜汁、萝卜汁、葱汁、草木灰和蘑菇汁分别与有机肥以1:7的比例混合,制成土壤添加剂,然后再将配好的不同土壤添加剂分别按1:30的比例加入到土壤中,混合均匀,种植上番茄,设有机肥处理作为对照,待番茄苗出土后,每隔7d测定一次番茄土壤根际微生物数量(主要测定土壤细菌,土壤真菌和土壤放线菌的数量)。测定结果表明,在整个测定期间,与有机肥对照相比,苜蓿汁与有机肥、韭菜汁与有机肥和木醋液与有机肥配制的土壤添加剂对土壤中微生物数量都有增加趋势。木醋液与有机肥配制的土壤添加剂在加入土壤15d,土壤细菌、土壤放线菌和土壤真菌数量就增加到最大,分别为1131.94%、191.67%和348.19%。Eight different soil amendments were generated by mixing eight kind of material (clover juice, leek juice, wood vinegar liquid, Chinese cabbage juice, radish juice, shallot juice, plant ash and mushroom manure juice) respectively with organic manure at proportion of 1:7.Then put the eight soil amendments into soil individually at proportion of 1:30, followed by mixing them evenly with soil. Tomato was planted, and set the organic manure treatment group as control. After the tomato seedling break through the soil, quantities of the soil microbes around the tomato root (primarily bacteria, actinomyces and fungi) were counted every 7 days during the whole process of experiment period. The result from this study indicates that, compared with control, clover juice measure, leek juice measure and wood vinegar liquid together with organic manure treatments can increase the quantities of microbes around the tomato root. 15 days post treatment with soil amendment made from wood vinegar liquid and organic manure, the number of bacteria, actinomyces and fungi reach their highest level, measured as 1131.94%?191.67% and 348.19% respectively.
