采用田间试验与室内化验分析相结合的方法,对花生（花育16）在露地栽培、荚果产量5 216.0 kg/hm2水平下植株N,P,K吸收特性进行了研究。结果表明,平均每生产100 kg荚果,植株需吸收N 4.554 kg,P2O51.537 kg,K2O 3.623 kg;比例为1.00∶0.34∶0.80。出苗后41～60 d是植株吸收N,P2O5,K2O最多的时期,分别占各自总吸收量的38.75%,37.19%,43.89%。收获时植株吸收N,P2O5,K2O主要贮存在荚果中,分别占总吸收量的59.97%,52.64%,32.14%。不同时期各器官中N,P2O5,K2O的含量不同。

Combining field experiment with indoor analysis,the assimilation characteristics of N,P and K of peanuts（Huayu 16） cropped outdoors was studied with the legume＇s yield level being 5 216.0 kg/hm2.The results showed that： to produce every 100 kg legumes,the plants needed to assimilate 4.554 kg N,1.537 kg P,and 3.623 kg K2O,with the proportion being 1.00∶0.34∶0.80.40 to 60 days after seedling emergence was the period in which plants assimilated most N,P2O5 and K2O,which were of 38.75%,37.19% and 43.89% of the total assimilation value,respectively.At harvest time,N,P2O5 and K2O assimilated by plants were mainly stored in the legumes,which were of 59.97%,52.64% and 32.14% of the total assimilation value respectively.In different periods,the contents of N,P2O5 and K2O in different organs were different.
