近几年来,越来越明显地可以看出合理安排輪作复种耕作制度,对实现粮食持續增产具有重要作用。从浙江省已实现粮食亩产八百斤生产单位的經驗来看,增产原因虽然是多方面的,但其中有一条共同經驗,就是因地制宜安排轮作复种制度,妥善处理用地与养地的关系, In recent years, it has become increasingly clear that a rational arrangement of rotation and cropping system can play an important role in achieving sustained grain output. Although Zhejiang Province has achieved the experience of producing 800 kg of grain per mu, the reasons for its increase are numerous. However, one of the common experiences is that the rotation system should be arranged according to local conditions so as to properly handle the relationship between the land and the raised land.
