摘　　要：通过垄畦栽冷渍型稻田早、中稻化肥不同施量及施用方法的田间试验,建立氮、磷、钾化肥施用量与产量的回归方程,推导出早、中稻氮、磷、钾化肥最佳施用量;在施肥量相等情况下,深施比表施肥效好,钾肥不足情况下,以稻草代钾肥同样取得较好增产效果。By using different fertilizer amount & method experiments in the cold waterlogged ridge rice field,We set uparegression equation of N,P,K fertilizer application amount and crop yield.With same fertilizer application amount,the effect of subsoil application is better than that of top soil application.
