花粳固优１号在５００ｋｇ／亩产量水平下，每生产１００ｋｇ籽粒需吸收Ｎ、１７７ｋｇ，Ｐ２Ｏ５、０８０ｋｇ，Ｋ２Ｏ、２１１ｋｇ。不同器官氮磷钾的含量不同，在成熟期：氮的含量，籽粒＞叶＞鞘＞茎；磷的含量，籽粒＞鞘＞茎＞叶；钾的含量，茎＞鞘＞叶＞籽粒。不同养分的主要吸收时期不同，氮主要在移栽到分蘖期吸收，磷主要在拔节到抽穗期吸收，钾主要在分蘖到拔节期吸收 At the output of 500kg / mu, the flower japonica Guanyou 1 is required to absorb N, 177kg, P2O5,080kg, K2O, 211kg per 100kg grain. The contents of nitrogen, phosphorus and potassium in different organs were different. At the maturity stage, the contents of nitrogen, grain> leaf> sheath> stem and leaf, phosphorus content, kernel> sheath> stem> leaf, potassium content, stem> sheath> leaf> grain. The main absorption period of different nutrients is different, nitrogen is mainly absorbed in transplanting to tillering stage, phosphorus is mainly absorbed at jointing stage and heading stage, potassium is mainly absorbed at tillering to jointing stage
