为促进现有的种植结构由“粮-经”二元种植结构向“粮-经-饲”三元种植结构发展,针对黑龙江省北部地区早熟作物收获后农闲期长、光温资源浪费、生态环境恶化等问题,通过早熟作物收获后复种饲料油菜,不仅可以提高光、温、水资源的利用率,增加复种指数,而且有利于现阶段黑龙江省“镰刀弯”地区玉米种植结构调整。从复种饲料油菜的发展与复种模式、饲料油菜种植与利用、饲料油菜的效益三方面论述了饲料油菜在黑龙江省的推广与应用。
In order to promote the development of the current planting structure from the “grain-economic” binary planting structure to the “grain-economic-feed” ternary planting structure, aiming at the problem that the early maturing crops in the northern part of Heilongjiang Province have a long aftermath, Waste of resources, deterioration of ecological environment and other issues. After rapeseed crop is harvested by multiple cropping, it can not only increase the utilization rate of light, temperature and water resources but also increase the multiple cropping index, which is also beneficial to the corn in Heilongjiang Province at the moment of “sickle bend” Planting structure adjustment. This paper discusses the popularization and application of forage rape in Heilongjiang Province from three aspects: the development of multi-forage rape and multiple cropping patterns, the cultivation and utilization of forage rape and the benefit of forage rape.
