配方施肥是提高肥料效益,降低生产成本,促进农业增产增收的重要措施。但受农民文化素质和化肥产、销体制影响,难以具体化,盲目施肥的情况十分严重。为了研究配方施肥对水稻的增产效应及大面积示范推广途径,使有限的肥料发挥更大的增产效果,1989年我们在水稻上进行了多点试验及大面积生产示范,增产效果显著,受到农民欢迎,现总结如下:
Formula fertilization is to improve fertilizer efficiency, reduce production costs and promote agricultural production and income an important measure. However, due to the cultural quality of peasants and the system of production and sales of fertilizer, it is difficult to substantiate the situation. The situation of blindly applying fertilizers is very serious. In order to study the yield-increasing effect of formula fertilizers on rice and the large-scale demonstration and promotion ways to make the limited fertilizers exert more stimulation effect, in 1989 we carried out multi-point experiments and large-scale production demonstration on rice, and the yield increase was remarkable. Welcome, are summarized as follows:
