How to grow nitrogen-free fertilizer rice

摘要

PROBLEM TO BE SOLVED: To provide a method for cultivating rice for harvesting palatable rice without causing any environmental pollution by eliminating axial roots through developing rice roots near the ground surface without application of any nitrogenous fertilizer as basal fertilizer or additional fertilizer. SOLUTION: This method for cultivating rice comprises the following practice: using no nitrogenous fertilizer as basal or additional fertilizer, a rooting promoter is spread on the ground surface and a phosphoric acid-containing aqueous solution is vertically spread on the leaves and the ground surface to 'develop the rice roots near the ground surface by the synergistic effect of both the rooting promoter and the phosphoric acid-containing aqueous solution and eliminate the axial roots.
