摘要
玉米是C4作物,其高产稳产关乎到粮食安全战略。近年来,随着我国化肥使用量零增长的逐步推进,化肥的精确、科学、合理地施用备受关注。我国玉米现阶段施肥主要存在的问题是氮肥用量偏高、氮磷钾配比不均衡、肥料利用率低、基肥和前期施肥比例过大等问题。玉米配方施肥是实现玉米高产优质和节本增效的一项关键技术。本研究旨在改变传统玉米施肥的观念,归纳总结玉米科学施肥技术要点,以期指导玉米规模化安全生产,促进节本增效、节能减排的现实需要。
Maize is a crop of carbon 4,its high and stable yield is related to the strategy of food security.In recent years,the accurate,scientific and reasonable application of chemical fertilizer has attracted much attention with the gradual advance of zero increase of chemical fertilizer usage in China.The main problems of maize fertilization in China are high application amount per mu,unbalanced fertilization,low fertilizer utilization rate,high ratio of base fertilizer and early fertilization.Maize formula fertilization is a key technology to achieve high yield,high quality and cost saving.The purpose of this study is to change the traditional concept of maize fertilization and summarize the technical key points of maize scientific fertilization,to guide the largescale safe production of maize and promote the practical needs of cost saving,efficiency increasing,energy saving and emission reduction.
