Abstract: In view of effect of high temperature in summer on growth of leafy vegetables in solar greenhouse，a comparative experiment was conducted among three oversummer planting patterns：soil+shading net，matrix+shading net and matrix+shading net+wet curtain.Effects on temperature and humidity of greenhouse，growth of leafy vegetables and economic benefits were analyzed.Preliminary results showed that on hottest day of year，average outdoor daytime（8：00am～15：30pm）temperature was 32.5 ℃.Average daytime temperature of soil+shading net，matrix+shading net planting mode was 7.1 and 6.4 ℃ higher than that of matrix+shading net+wet curtain planting mode，respectively.Meanwhile，average relative humidity of the indoor daytime was lower than that of the soil+shade，and average relative humidity of the substrate+wet curtain was the highest.According to yield and benefit，yield of Brassica pekinensis and Brassica japonica Sieb was the highest under mode of matrix+sunshade+wet curtain mode，the highest yield of rapeseed planted was under matrix+sunshade mode.Three kinds of leaf vegetables were the best planting efficiency under substrate+shade+wet curtain planting.
