春花连作稻三熟制(下称三熟制)是目前加兴专区比较优良的耕作制度,是迅速增产粮食的主要途径。例如桐乡大麻公社1959年扩种了13,144亩三熟制田,获得了平均亩产粮食1,629斤的高额产量(其中早稻604斤,晚稻720斤,春花266斤),比草子连作稻二熟制田增产17%,比春花单季稻二熟制田增产58.5%。但是,随着三熟制面积的日益发展和冬种面积的不断增加,使晚秋作物(晚稻)的收获季节和春花作物的种植时间相应地延迟,造成了前后作物季节安排上的新矛盾。1960年加兴专区各地,在春花作
Chunhua continuous cropping rice three cooked system (hereinafter referred to as three cooked system) is currently Jiaxing prefecture relatively fine farming system is the main means of rapid production of grain. For example, Tongxiang Hemp Commune expanded planting of 13,144 mu of three-cropping land in 1959 and obtained the high yield of 1,629 kg per mu of grain per mu (including 604 kg for early rice, 720 kg for late rice and 266 kg for spring flower) Field increase of 17%, spring flower than double cropping single yield 58.5%. However, with the growing of the three-cropping system and the continuous increase of the winter planting area, the harvest season of late autumn crops (late rice) and the planting time of the spring flower crops are correspondingly delayed, resulting in a new contradiction in the seasonal arrangement of the pre- and post-crop crops. In 1960 Jiaxing area around, in the spring flowers
