The experirent set up six treatments, respectively using 0,20%, 40%, 60%, 80% and 100% of the mushroom to instead of peat. The results showed that, effects of different ratios of mushroom substrrate on tomato seedlings biological index,biomass,seedling index and accumulation of nitogen phosphorus potassium in various organs were consistent,T2T1T3T4CKT5. Seedling’s indicators with 40% mushroom compost were higher than control group and other treatments. The accumulation of three nutrient elements in tomato seedlings were nitrogen: 22.8mg / strain; Phosphorus: 3.2mg / strain; Potassium: 8.4mg / strains. It is recommended to use 40% of mushroom compost instead of peat and nutrient ratio of N: P: K = 7:1:3 can obtain good breeding results. Key words:mushroom compost;tomato;accumulation and distribution of nitogen phosphorus potassium;seedlings strength of plants 引言 随着经济发展，社会进步，人们的生活水平不断提高，对农产品的需求越来越高，造成
