The objective was to reveal characteristics of nutrients accumulation and distribution in early and ratoon rice under different cultivation models; Dry weight and nutrients contents in the rice plants were determined at different developmental stages, using a new combination hybrid rice II Youhang 1 under super high-yield cultivation and conventional cultivation models;The results showed that the accumulated N, P and K in the plant were 15.06 g/m2, 4.58 g/m2 and 15.8 g/m2 at the fully ripening stage under SHC models, which were 47.2%, 21.2% higher and 9.1% lower than those under CC models respectively.

探讨不同栽培模式早稻-再生稻水稻的养分积累动态和分配特征；以杂交水稻新组合Ⅱ优航1号为材料，采用超高产栽培和常规栽培模式，通过测定水稻各生育期的干物质积累和养分含量变化；超高产模式头季稻稻株N含量在全生育期均高于常规模式，孕穗前稻株P含量、黄熟前及再生稻K含量亦明显高于常规模式。
