Abstract: By means of relational analysis of grey system theory and variance analysis, the primary factor influencing on yield of Pleurotus ostreatus growing in vinegar waste were studied. The results indicated that seed quantity was the most primary factors while the composition of bran was secondary and the carbamide content had no markble influence. On the basis of analysis above, the suitable composition of culture material should be consist of 80% of vinegar waste and 20% of bran,with 1% of phosphate fertilizer, 2% of gypsum powder and 3% of lime powder and the seed quantity is 20%.
