杂交早稻生产在我省尤其在浙中南地区占有愈来愈重要的地位。其产量直接关系到该地区全年粮食总量。“三高一稳”栽培法是杂交早稻取得高产的有效途径。文章通过设立麦茬杂交早稻不同施氮量与施氮方法试验，探明氮肥用量对杂交早稻产量形成与其苗、蘖、穗、粒的相关性，及不同施氮方法对杂交早稻库源流协调的影响；明确了最佳用氮量与最佳施氮方法，进一步完善了杂交早稻的“三高一稳”高产栽培技术。
Early hybrid rice production in our province, especially in central and southern Zhejiang occupy an increasingly important position. Its output is directly related to the total annual grain output in the area. “Three highs and one stability” cultivation method is an effective way to obtain high yield of early hybrid rice. Through the experiment of different nitrogen application rate and nitrogen application rate in early-season hybrid rice, the correlation between yield and its seedling, tiller, spike and grain of early hybrid rice and the effect of different nitrogen application methods on the coordination of source and flow of early hybrid rice ; Clear the best amount of nitrogen and nitrogen application method to further improve the hybrid early rice “three high and one stable” high-yielding cultivation techniques.
