Zusammenfassung:The invention provides a fertilizing method for double-season rice of which the previous crop is winter potatoes. Base fertilizer is not applied to the early rice and the late rice, and top dressing is performed in the late period. According to the fertilizing method, the fertilizing amount can be decreased to about 80% of the conventional fertilizing amount, the yields of the obtained early rice and late rice are both high, the quality is good, and the yields and the quality have little difference with those of early rice and late rice which are obtained through a conventional fertilizing method. Accordingly, through the fertilizing method, the fertilizer utilization rate and the production benefit can be increased, the production cost is reduced, and too much pollution cannot be caused to the environment. 本发明提供了一种前茬为冬种马铃薯的双季水稻施肥方法,早晚双季水稻不施基肥,后期进行追肥。该施肥方法的施肥量可以下降至常规施肥量的80%左右,而所获取的早稻和晚稻的产量均较高,品质较好,与常规施肥法所获取的早稻、晚稻的产量和品质差别不大。即本发明所提供的施肥方法能够提高肥料利用率和生产效益,降低生产成本,且不会对环境造成过多的污染。
