Abstract: In order to actively explore the diversity of solid substrate in China,so that fresh and low-cost Sonchus asper can be eaten in northeast Yunnan Province in winter,and improve the comprehensive utilization level of agricultural waste,the Sonchus asper was taken as the test material.Set V （red soil）∶V （maize stalk residue）=1:1 （T₁）,V （red soil）∶V （maize stalk residue）=3:1 （T₂）,V （red soil）∶V （maize stalk residue）=5:1 （T₃）,V （red soil）∶V （maize stalk residue）=1:5 （T₄）,V （red soil）∶V （maize stalk residue）=1:3（T₅）,V （perlite）∶V （maize stalk residue）=1∶2 （T₆）,V （river sand）∶V （maize stalk residue）=1∶2 （T₇）,V （coconut bran）∶V （maize stalk residue）=1∶2 （T₈）,and maize stalk residue （T₉） were treated with 9 cultivation substrates,and the local red soil was used as con‐trol （CK）.To study the application effect of adding different proportions of granular maize straw residue in the cultivation of Sonchus asper,and explore the effects of maize straw residue on physical and chemical properties,water holding capacity,phenotypic proper‐ties and yield of Sonchus asper.The results showed that the pH value,conductivity and density of the substrate and the yield of Son‐chus asper were changed by adding different proportion of maize straw residue.Under T₂treatment,the comprehensive evaluation was the best and the yield was high.The quality of Sonchus asper planted with pure maize straw residue was better.Considering the economic cost,T₂treatment can be selected,which can be planted outdoors and indoors.Considering the clean and refreshing,T₉treatment can be selected,and it can be planted on the balcony.
