| Abstract: | 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. |
