1970年以来,苏州地区的耕作制度由传统的一年稻麦两熟,大面积改革为麦稻稻三熟。改制以后的经济效益究竟如何?由于评价的角度或者评价的方法不同,得出的结论也不同。 我们通过实地典型调查,运用数理统计和线性规划法进行定量分析,来探讨这一问题。本研究着重对现有几种主要水稻熟制形式进行经济效益分析,并探讨如何因地制宜确定一个生产队的合理种植方案。 Since 1970, the system of farming in Suzhou has been transformed from the traditional one-year rice and wheat crops to the third generation of wheat and rice. After the restructuring of the economic benefits of what? As the evaluation of the point of view or evaluation of different methods, draw conclusions are also different. We explore this issue through field-based surveys, quantitative analysis using mathematical statistics and linear programming. This study focuses on the analysis of the economic benefits of several existing forms of cooked rice and discusses how to determine a reasonable planting plan for a production team according to local conditions.
