摘要
怎样对间作试验中获得的数据进行数学分析,对间作效果作出评价,是当前间作研究中的一个重要问题。本文综述了这方面的文献,并对其中3种主要的分析方法(指数分析法、双变量分析法和模拟方法)作了较详细的介绍,并对其中存在的问题进行了讨论。
How to analyse the data obtained from intercropping experimentsand evaluate the intercropping effects is an important problem in intercroppingresearches.Some papers relating to this field were reviewed and three mainmathematical methods(index analysis,bivariate analysis and simulation)were introduced in detail.Discussion on the problems and limitation of themethods were given in the paper.
