作者在总结前人施肥模式成果的基础上,提出了稳穗增粒施肥模式。通过4年的田间试验,比较和分析了增产、节肥的效果及原因。结果表明:该模式比当前推行的3种参比模式增产5％～17％。生产7500kg/hm稻谷的氮肥用量控制在105～120kg/hm,至少可以节约氮肥25％～30％。在中高肥力土壤上,该模式是取得高产稳产和节肥的一个良好的选择,对节约能源和农田环境保护也有重要意义,具有推广价值。
On the basis of summarizing the achievements of the predecessors’ fertilization mode, the author put forward the mode of stabilizing spike and fertilization. Through four years of field experiments, the effects and reasons of yield increase and fertilizer control were compared and analyzed. The results show that this model yields 5% ~ 17% more than the current three reference modes. The amount of nitrogen fertilizer used to produce 7500kg / hm paddy is controlled at 105 ~ 120kg / hm, at least 25% ~ 30% of nitrogen fertilizer can be saved. In medium-high fertility soils, this model is a good choice to achieve high and stable yield and fertilizer saving. It is also of great significance to conserve energy and farmland environmental protection and has the promotion value.
