Abstract:In order to explore the relationship between the absorption of medium and trace elements in rice and rice quality under different rice co-cropping with shrimp modes, the field experiments were conducted in this study with different lobster species and densities. Four treatments were designed: rice monoculture (R), rice co-cropping with Procambarus Clarkii in low density (RCL), rice co-cropping with Procambarus Clarkii in high
