一项新技术或一台新机具的应用,往往会给农业生产带来明显效益。然而,承包责任制落实后,大部分村把土地分得精光,试验只能在个体农户的土地上进行。而这样做的困难很大。因为农户不了解其作用和意义,不愿承担风险和麻烦,这种思想工作很难做。如果村集体留有试验田,上述矛盾便迎刃而解。因此,各村在土地调整时,应留出一部分试验田,数量不一定多。但要有代表性,高产、中产、低产田各占一定比例。一旦新技术、新机具在试验田上应用成功,就 The application of a new technology or a new tool often brings significant benefits to agricultural production. However, after the implementation of the contract responsibility system, most villages have allocated more land and the tests can only be conducted on the land of individual farmers. And it is very difficult to do so. Because farmers do not understand its role and significance, are not willing to take risks and troubles, this ideological work is difficult to do. If the village collective experimental field, the above contradictions will be solved. Therefore, in the adjustment of the land in villages, a portion of the experimental fields should be set aside, not necessarily in large numbers. However, there should be representative, high-yielding, middle-yielding and low-yielding fields each with a certain proportion. Once the new technology, new equipment in the experimental field applied successfully
