石灰性田超级稻“3414＋1”肥料效应研究

采用“3414＋1”回归设计，在融安县石灰性稻田进行了超级稻施用氮、磷、钾、锌肥的效果试验。结果表明：氮、磷、钾肥合理搭配结合施用锌肥，可以显著提高超级稻的产量。通过建立模型和综合分析，最后选择以磷的一元二次肥效模型作为该地超级稻生产的推荐施肥模型，该模型提供的施肥参数为施纯氮210kg／hm2,五氧化二磷72．7kg／hm2,氧化钾210kg／hm2，超级稻理论最高产量为10429kg／hm2。...

Summary:采用“3414＋1”回归设计，在融安县石灰性稻田进行了超级稻施用氮、磷、钾、锌肥的效果试验。结果表明：氮、磷、钾肥合理搭配结合施用锌肥，可以显著提高超级稻的产量。通过建立模型和综合分析，最后选择以磷的一元二次肥效模型作为该地超级稻生产的推荐施肥模型，该模型提供的施肥参数为施纯氮210kg／hm2,五氧化二磷72．7kg／hm2,氧化钾210kg／hm2，超级稻理论最高产量为10429kg／hm2。
Bibliography:The effects of nitrogen, phosphorus, potassium and zinc fertilizer application on super hybrid rice were studied by u- sing ＂3414 ＋ 1＂ regression design in calcareous paddy fields of Rong＇ an county. The results showed that the reasonable application of nitrogen, phosphorus and potassium fertilizer combined with zinc fertilizer could significantly improve the yield of super rice. A one - place quadratic phosphorus fertilization model was recommended for super rice production based on model and comprehensive analysis. Fertilization parameters were acquired as follows ： nitrogen 210 kg/hm2, phosphorus pentoxide 72.7 kg/hm2, and potassium oxide 210 kg/hm2. The theoretical maximum yield was 10429 kg/hm2.
