二、场地选择在农村,合理地选择场地,是一个常见的问题。例如,播种时,将秧田设置在什么地方,使插秧时运秧的劳力最省?收割时,将晒场设置在什么地方,使运稻路线最短?等等,这些都涉及到合理选择场地的问题。下面通过实例,介绍几种选择场地的方法。1、晒场的选择(图上作业法)[例4]平村生产队有六片稻田。它们的实际位置绘于图14,图中的方格及方格内的数字表示各片稻田及估计的产量,(斤)、它们之间的连线为可运行的道路。问晒场应设置在什么地方,使所花运力最省?
Second, the site selection In the countryside, a reasonable choice of venue is a common problem. For example, when sowing, where are the seedlings arranged so that the most labor-saving seedlings can be transplanted at the time of planting? Where are the drying places laid at the time of planting? . The following examples, introduce several ways to choose the venue. 1, the drying field of choice (Figure Act) [Example 4] Ping Village production team has six rice fields. Their actual location is shown in Figure 14. The figures in the boxes and boxes indicate the paddy fields and the estimated yield (kg). The connection between them is a runnable road. Asked the drying yard should be set in what place, so spend the most provinces?
