改革耕作制度,选择优良品种等,一般都需要通过试验。如何安排试验,还有一个方法问题。毛主席教导我们:“我们不但要提出任务,而且要解决完成任务的方法问题。我们的任务是过河,但是没有桥或没有船就不能过。不解决桥或船的问题,过河就是一句空话。不解决方法问题,任务也只是瞎说一顿。”一个 Reforming the farming system and choosing fine varieties generally require experimentation. How to arrange the test, there is a methodological problem. Chairman Mao taught us: "We must not only propose a task, but also solve the method of accomplishing it. Our task is to cross the river, but we can not cross the river without a bridge or without a boat. Empty words .Do not solve the problem, the task is just nonsense
