Abstract: In order to promote the matrix application of rotten maize straw,in this study,the compost straw of maize used as matrix was the research object,spinach,lettuce and Eruca sativa Mill.as experimental crops.This experiments conducted in the greenhouse.The effects of the proportion of straw compost on the growth of three vegetables and soil enzyme activities were investigated.The results showed that the 70% straw compost combined with 30% arable soil according to the volume ratio was beneficial to the yield formation of spinach and Eruca sativa Mill..And 50%of straw compost was conducive to the yield formation of lettuce.Soil enzyme activities in seeding matrix of lettuce and Eruca sativa Mill.showed increased with compost straw of maize adding,then they did show significant difference between treatments of spinach planting.
