摘要
通过田间试验，提出冬小麦水肥增产耦合效益的田间试验设计、试验统计分析、水肥因子增产耦合效应和最佳水肥投入经济性分析等，突出了统计分析的基本方法、优化方法和计算机技术的应用。
Based on field test results,the design of field tests on interaction of irrigational water and fertilizer application for yield increase of winter wheat, the statistical analysis on the tests,the interaction and optimal input of irrigation water and fertilizer application for yield increase and the economic analysis were described with an emphasis on the basic methods of statistical analysis,the method of optimization and the application of computer technology.
