小麦水肥产量效应研究进展

Research achievemens on the relationship between wheat yield and water and fertilizer

小麦产量与水肥因子的关系研究能为提高小麦产量提供科学依据和实用的田间管理技术。通过多年的小麦水肥产量效应试验研究并结合同类地区的有关研究结果，探讨了小麦产量与水分（包括：降水、底墒、灌水）因子的关系；同时也分析了其与肥力因子（包括：化肥、有机肥、施肥方式、肥料配合技术）的关系。提出的一些综合分析可为提高小麦产量水平参考；研究结论也反映了该地区的小麦水肥产量关系的研究进展。

The study on the relationship between wheat yield and water fertilizer playsa very important role in the practice of wheat yield improving,and deepen the understanding of ways used in increasing grain yield. In this paper, the authors had analyzed the data and documents from either themselves' or other researchers'. They had discussed how wheat yield was affected by water factors (including soil moisture, rainfall and irrigation) and by fertilizer (N, P, K, mane and methods of fertilizing). They indicated that wheat yield could be increased if their research results can be put into practice. This was also the state of art on this research field in China.
