摘要
水稻保墒旱直播氮肥施用量试验结果表明:水稻保墒旱直播氮肥最佳施用量为274.5 kg/hm2,水稻最高理论单产为9 957.30 kg/hm2。此时的肥料利用率最大,水稻单产最高。
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.
