摘　　要：通过田间试验研究了长效硅钾肥在信阳水稻上的肥料效果。结果表明 ,长效硅钾肥对本区的水稻有显著的增产作用 ,其肥效优于同钾量的化肥。By field experiments, we have studied the effect of the silicon kalium fertilizer with long term effectiveness on the paddy in Xinyang area. The result indicated that the silicon kalium fertilizer with long term effectiveness can improve the paddy yield remarkably in this area, the effect of which is better than that of other fertilizers with the same content of kalium.
