摘要
[目的]分析辽西地区林农复合经营模式下影响玉米产量的主要因素，为选择适合该地区的高产玉米种植方式提供参考。[方法]通过试验方法研究了影响玉米产量的主要因素（玉米品种、种植密度、有机肥施用量、耕作方式），利用 Matlab 软件中的 anova1函数对试验数据进行单因素方差分析。[结果]通过试验测得不同因素在不同设置下的玉米产量和生物产量数据，将数据带入 Matlab 软件计算得到试验数据的方差分析结果。[结论]玉米品种、种植密度、有机肥施用量均对玉米产量影响显著，在实际生产中应进行适当选择；耕作方式对玉米产量影响不大，可以在玉米种植中适当减少耕作次数。
Abstract
Objective] The aim was to analyze main factors influencing maize yield under agroforestry operation mode in western Liaoning, to provide reference for choosing appropriate cultivation way for maize.[ Method] The main factors influencing maize yield ( variety, planting density, organic fertilizer application amount and tillage method) were studied, single factor variance analysis was conducted on data by using anoval function of Matlab software.[ Result] The maize yield and biological yield under different treatments were obtained by experiment, through Matlab procedure, the variance analysis results were calculated.[Conclusion] The varieties of maize, planting density, applied a-mount of fertilizer affect maize yield significantly, and should be chosen appropriately in practice; but farming methods have little effect on yield, times of cultivation can be reduced in practice of maize planting.
