Abstract: This research studies the effect of the combination of rice ridge cultivation and rice-fish-chicken cultivation on the growth of the rice root system. On the basis of the researches carried out by other scholars on rice ridge cultivation, rice-fish cultivation, and rice-chicken cultivation, this research came up with a creative planting and breeding technique that features combining chicken and fish breeding with rice ridge cultivation. This research was based on a field comparison experiment that consisted of conventional rice ridge cultivation (CK), rice ridge cultivation with fish breeding (RF), rice ridge cultivation with chicken breeding (RC), and rice ridge cultivation with fish and chicken breeding (RFC). The growth trait and biological activity of the rice root system under rice-fish-chicken ridge cultivation was explored. The results showed that there were differences in the structure and biological property of the roots among different cultivation models during the two-year experiment. RFC and RC had no insignificant differences in root dry matter, root shoot ratio, root volume, root number, maximum root length, and root antioxidant activity and bleeding sap after full heading, which were slightly higher than CK (some indicators had significantly difference). Compared with CK, the root volume of RFC and RC was increased by 0.77%-14.05% and 0.10%-13.88% respectively, and the antioxidant activity was increased by 2.15%-13.48% and 0.64%-10.05% respectively. Compared to CK, RF showed a downward trend of all indexes related to the root structure, the antioxidant activity, and bleeding sap, in which the root dry matter, root volume, the antioxidant activity, and bleeding sap were reduced by 24.62%-50.70%, 7.80%-47.45%, 10.49%-21.68% and 24.39%-39.25% respectively. In conclusion, rice-fish-chicken ridge cultivation and rice-chicken ridge cultivation had a higher level in root morphological index compared with conventional rice ridge cultivation,such as root volume, root shoot ratio, root number and maximum root length. The biological activity of root system was improved after full heading stage and the aging of the root system at later stage was reduced, thus ensuring the growth of the overground parts of the rice and its yield.
