    The result of an experiment on the amount of nitrogen application for soil moisture preservation and dry direct sowing rice shows that the optimal nitrogen application amount for soil moisture preservation and dry direct sowing rice is 274.5 kg/hm2 and the highest theoretical yield of the rice is 9,957.30 kg/hm2. With this the fertilizer utilization efficiency and the yield are highest.
