摘要：

套种可争取季节,提高光、热、水的利用率。在华北复杂多变的自然条件下,套种可以趋利避害,产量较稳。但由此也产生了一系列种内和种间竞争,例如边行优势与减少播种行的矛盾、群体与个体的矛盾、共生期作物之间的矛盾等。这就需要从作物搭配、田间结构和水肥管理等方面予以调整。麦后复播便于机械化,同时不存在两种作物共生

Abstract: There are several patterns of double cropping in wheat fields in North China,relay-intercroppingand sequential cropping are two main patterns.On the basis of field experiments and investigationsfor a five year(1973～1978)period,an effort is made to discuss the utilization of solar energy,cropeompeti
