以大棚蔬菜为前茬的菜稻复种模式是一项很有发展前途的立体农业生产模式。自 1 996年开始立项研究、示范推广 ,至 1 998年 3年时间内在铁岭、灯塔等市县推广了约 870ｈｍ2 。1 棚菜复稻的高产高效原理1 1 提高了自然资源利用率北方稻区由于受温光条件限制 ,传统上都是种一季
The vegetable-rice multiple cropping model with the vegetable shed in the greenhouse is a very promising three-dimensional agricultural production mode. Since 1996, research and demonstration projects have been started and demonstration projects have been carried out. Up to 870hm2 was popularized in cities and counties such as Tieling and Beacon by the year of 1998. 1 greenhouse vegetables high yield and efficiency of rice principle 1 1 to improve the utilization of natural resources in northern rice due to temperature and light conditions, are traditionally a season
