通过对冷浸单季稻增施磷肥钾肥试验表明:增施磷肥对冷浸田水稻增产效果不明显;增施钾肥对冷浸田水稻增产效果极显著,与对照相比,每增加稻谷产量63.2kg/667m~2,增幅12.9%;平衡施肥对冷浸田水稻增产显著。
The experiment of applying phosphate fertilizer and potassium fertilizer to cold-soaked single-cropping rice showed that the effect of increasing phosphorus was not obvious to paddy rice in cold-dip field; the effect of increasing potassium fertilizer on yield of paddy rice was very significant. Compared with the control, 667m ~ 2, an increase of 12.9%; balanced fertilization on cold paddy rice yield significantly.
