三、农业系统方法 农业各个专业学科的研究,最通用的传统方法是试验研究加上生物统计。即选定有代表性的试验田,进行不同处理的对比试验,然后用生物统计方法,作出不同处理间的差异显著性分析。这一套方法在农业科学发展中,获得很大成功,今后仍将继续使用。但必须看到,这种方法亦有很大的局限性:它不能反映农业整体内部大量因子间的错综复杂的关系;一般不能反映许多因子间的动态的数量关系;由于传统方法考虑因子很少,因此,根据传统方法,不能真正作出农业上的最优决策。例如,
Third, the agricultural system of agricultural research disciplines in various disciplines, the most common traditional method is to add experimental research and biometric statistics. That is, a representative experimental field was selected and comparative experiments of different treatments were conducted. Then, the significance of the differences among the different treatments was analyzed using the biometric method. This set of methods has enjoyed great success in the development of agricultural science and will continue to be used in the future. However, it must be observed that this method has its own limitations: it can not reflect the intricacies of a large number of factors in agriculture as a whole, generally can not reflect the quantitative relationship among many factors, and because of the small consideration of traditional methods, Therefore, according to the traditional method, the best agricultural decision can not be made. E.g,
