Super rice as a representative variety type of high-yield rice was successfully developed to greatly increase paddy output in China. The large of root biomass, root weight density, root length, root length density, root diameter, and deep soil root biomass are the main biological characteristics of super rice root. The high of root oxidation activity, total root absorbing surface area, active absorbing surface area and root cytokinin (root zeatin and zeatin riboside) content are the important physiological basis of super rice root. In rice cultivation practice, fertilization management, water ...
