摘要： 为揭示中熟超高产大豆N、P2O5、K2O养分吸收分配规律。田间研究了975 m3/hm2 (W1)、 1575 m3/hm2 (W2)、2175 m3/hm2 (W3)、2775 m3/hm2 (W4) 4种滴水处理对‘新大豆27号’N、P2O5、K2O吸收的影响。结果表明，增加花荚期滴水量，明显增加花荚期叶、茎中N、P2O5、K2O百分含量和积累量，并大幅度提高籽粒产量；明显提高N、P2O5、K2O的收获指数、每生产100 kg籽粒所需N、P2O5、K2O量和K2O的比例。籽粒产量在6082.6~6404.7 kg/hm2，每生产100 kg籽粒需积累N 6.4~6.6 kg，P2O5 1.4 kg，K2O 4.6~5.2 kg。适宜的滴水量大幅度提高了花荚期N、P2O5、K2O积累速率和K2O的比例是产量增加的重要原因。

Abstract: The paper aims to reveal the rule of N, P2O5, K2O accumulation and distribution of the super-high-yielding production of soybeans. 4 different dripping amount treatments of 975 m3/hm2 (W1), 1575 m3/hm2 (W2), 2175 m3/hm2 (W3), 2775 m3/hm2 (W4) were conducted in the field to study their effects on N, P2O5, K2O absorption by ‘Xindadou 27’. The results showed that increasing the amount of dripping water during flower period could significantly increase the percentage content and accumulation of N, P2O5, K2O in the leaves and stems during flower period, and increase grain yield substantially, the harvest index of N, P2O5, K2O significantly, and the required amount of N, P2O5, K2O and the proportion of K2O of every per 100 kg grain production. N 6.4-6.6 kg, P2O5 1.4 kg, K2O 4.6-5.2 kg was required to accumulate to produce every per 100 kg grain under the grain yield of 6082.6-6404.7 kg/hm2. The suitable amount of dripping water in the flower period can substantially increase the accumulation rate of N, P2O5, K2O and the ratio of K2O, that is a crucial reason for the increase in production.
