冬油菜是泾河川传统的油料作物。由于冬油菜跨年生长,生长期长,油菜收后复种早熟玉米、糜谷等作物,只能达到二年三熟。这在人多地少复种指数要求高的地区,扩大冬油菜种植面积势必影响粮食生产。为了解决粮油生产争地的矛盾,泾川县城关公社水泉寺大队农科站近几年来积极开展了粮油间作套种和粮油二熟试验。目前试验出比较成功的有:春油菜→复种谷子、冬小麦→复种油菜等二种粮油二熟形式,为实现粮油双丰收,创出了新路。一、以春油菜为前茬,后季复种谷子实行油粮一年二熟
Winter rape is Jing River traditional oil crops. As a result of winter rape’s New Year’s Eve growth, long growth period, rapeseed recovery of early maturing corn, Mi Gu and other crops, can only reach three years cooked. This is a region where the requirement for multiple cropping and multiple cropping is low, and expanding the planting area of winter rape will inevitably affect grain production. In order to solve the contradiction between grain and oil production disputes, Jingchuan County Commune Shuizumi Temple Brigade Agricultural Station in recent years actively carry out intercropping of grain and oil intercropping and grain and oil two trials. Currently tested more successful are: spring rape → milled multiple millet, winter wheat → rapeseed and other two kinds of two kinds of grain and oil in two forms, in order to achieve double harvest of grain and oil, creating a new road. First, the spring rapeseed crop, the second quarter of the implementation of the multi-crop grain two crops a year
