摘　　要：通过水稻本田期主要生育期与产量构成因素的关系建立W模型图,同时利用相应的W模型施肥方法与当地的常规施肥方法进行小区比较试验,研究不同施肥方法对水稻的增产作用。结果表明,水稻W模型施肥方法比常规施肥方法能有效地提高成穗率和结实率,增加每穗结实粒数,从而达到增加水稻产量,为推广应用水稻W模型高产施肥法提供科学依据。Diagram 'W' was formed by the relationship between the main growth period and the factors make up of the yield of rice. The results of fertilizing by the way of diagram 'W' and the normal way were compared by experimental zones, in order to find the relationship between fertilization and the products. The result shows that rice fertilized by the way of diagram 'W' can effectively improve the rate of setting panicles, fruiting and the amount of grains of each spike than by the normal way, thus the yield can also be improved. It gives evidence for the extension and appliance of the high yield of rice fertilized by the way of diagram 'W'.
