摘要：

近年来，随着玉米高产品种的大量种植，玉米产量不断提高的同时，化肥用量也在增加，搞好玉米的生产与施肥是直接关系到高效农业发展的重大问题。此研究以‘辽单527’为试材，通过设置不同氮肥、磷肥和钾肥的肥料组合，对其产量和农艺性状的施肥效应进行了研究。结果表明，每公顷施N 135.0~180.0 kg、P2O5 75.0~120.0 kg、K2O 90.0~120.0 kg，‘辽单527’的产量较高。不同肥料效应试验中，‘辽单527’处理间产量和处理间秃尖长度的差异均达极显著水平。‘辽单527’的穗粒数与产量呈正相关关系。磷肥和钾肥效应试验中，‘辽单527’处理间百粒重的差异均达显著或极显著水平。合理的氮、磷、钾肥配施可以显著提高‘辽单527’的产量，其中，N4P4K2处理，‘辽单527’的产量最高。

Abstract:

In recent years, the yield of maize was increased by planting many high-yielding cultivars with more chemical fertilizers input. Do well in maize production and fertilizer application was related to key problem of developing high-efficiency agriculture. Effects of different N, P, K fertilizer combinations on yield and agronomic characters of ‘Liandan 527’ were studied. Results showed that the highest seed yield of ‘Liaodan 527’ was at N 135.0-180.0 kg/hm2, P2O5 75.0-120.0 kg/hm2, K2O 90.0-120.0 kg/hm2 fertilizer combination treatments. There were quite significant differences in seed yield and the length of barren tip of ‘Liandan 527’ among fertilizer treatments in different N, P, K fertilizer combination trials. Correlation analysis showed that the number of kernels per ear of ‘Liandan 527’ had a positive correlated with yield. The difference of 100-kernels weight between fertilizer treatments was significant at 0.05 or 0.01 in P and K fertilizer combination trials. The yield of ‘Liaodan 527’ was increased significantly by reasonable N, P and K fertilizer combinations applied, compared with other fertilizer combinations, N4P4K2 treatment had the highest yield.
