The effects of different mechanical-transplanting patterns and densities on the rice quality of Nanjing 9108 and Nanjing 5718,two japonica rice varieties with good taste quality,were studied.The results showed that compared with the conventional cultiva-tion mode,the rice-shrimp co-cropping mode increased the head milled rice rate,protein content and gel consistency of rice,and de-creased the chalky grain rate,chalkiness degree and amylose content.The rice-shrimp co-cropping had a greater impact on the starch RVA profile characteristic values.It increased the disintegration value,and reduced the attenuation value.The rice-shrimp co-crop-ping improved the appearance,hardness,viscosity,equilibrium degree and taste value of the rice.The mechanical-transplanting den-sity had a great influence on chalky grain rate and amylose content(P<0.01),significantly affected chalkiness degree and protein con-tent(P<0.05),and the taste quality of rice was significantly improved with the decrease of the mechanical-transplanting density.The interaction analysis showed that varieties,mechanical-transplanting densities,patterns,and their interactions had significant effects on rice quality.
