忻定盆地是由五台山、恒山和云中山构成的河谷盆地。该地区从1972年开始,进行了以麦秋套种为中心,变一作为二作、三作的耕制改革。这种改革究竟生产上需要不需要?与当地自然条件,生产水平适应不适应?有没有实际生产价值?是急需做出评价的。必要性耕作制度总是随着农业生产条件的相对稳定而稳定,又随着生产条件的不断改善而向前发展。近30年来,忻定盆地的耕作制度演变大体上经历了三个阶段。
Xin Ding Basin is composed of Wutai Mountain, Hengshan and Yunzhongshan valley basin. Beginning in 1972, the area began with the wheat-wheat intercropping system as the center, becoming the second and third crop farming reforms.

It is in urgent need of evaluation. Necessary tillage system is always stable with the relative stability of agricultural production conditions and stability, but also with the continuous improvement of production conditions and move forward. In the past 30 years, the evolution of the farming system in the Xinding Basin has generally gone through three stages.
