摘要
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 improve the development of ＂grain-cash crops＂ dual plantation structure to ＂grain-cashfodder crops＂ ternary plantation structure, in allusion to the questions of long slack season, wasting of light and temperature resources, ecological environment deterioration after early-maturing crops harvest in upstate of Heilongjiang province. By multiple cropping fodder rape not only increase light and temperature resources use ratio, add cropping index, and that avail to maize structural adjustment in ＂Camber＂ area in Heilongjiang province. The develop and multiple cropping pattern, plant and utilize were discussed, as well as the benefit of fodder rape in Heilongjiang province to popularization and application.
