摘要： 为研究超高产水稻新品种做为菜后稻的氮磷钾施肥效应和适宜用量问题，以‘两优616’为试验材料，采用“3414”肥料试验方案设计方法对其进行研究。结果表明，在高肥力菜田上平衡施肥能有效改善‘两优616’的农艺性状，提高有效穗、穗粒数和千粒重。氮磷钾肥平均增产效果分别为13.1%、2.9%和13.4%，氮钾肥的增产作用高于磷肥。氮磷养分主要存储在稻谷里，分别占总吸收量的63.8%和73.6%，但钾素有89.0%存储在稻草里。氮磷钾肥利用率分别为34.7%、24.7%和30.2%。在本研究条件下，经济施肥量为N 71 kg/hm2、P2O5 34 kg/hm2和K2O 101 g/hm2，三要素最佳施肥比例为1:0.48:1.42。研究结果为‘两优616’作为菜后稻的合理施肥提供了科学依据。

Abstract: We carried out a research on NPK fertilizer response of the super high- yield rice variety ‘Liangyou616’grown in vegetable field with‘3414’the optimum regression design. The results indicated that balanced fertilization could effectively improve the agronomic characters of‘Liangyou616’in high soil fertility, and increase efficient panicle, grain per panicle and 1000-grain weight. The average yield-increasing effect of N, P and K applications was 13.1%, 2.9% and 13.4%, respectively, the yield-increase effect of N and K was higher than that of P. The uptake of N and P nutrients was mainly stored in rice, which was 63.8% and 73.6% of total uptake of N and P respectively, while 89.0% of potassium was stored in the straw. The utilization ratio of N, P and K fertilization in season was 34.7% , 24.7% and 30.2% , respectively. The economic application rates were N 71 kg/hm2, P2O5 34 kg/hm2 and K2O 101 kg/hm2, the optimum ratio of the three elements was 1:0.48:1.42 under the test condition. The results provided a scientific basis for adequate fertilization on‘Liangyou616’as post-vegetable rice.
