抚宁县地处河北省东北部。当地≥0℃积温4163℃、≥10℃积温3795℃,无霜日174天,在农作物种植区域上属于春粮和春花生一熟制产区。在生产实际中严重存在着粮油争地和单纯种植一茬粮油作物经济效益偏低问题。小麦、花生、大豆三茬套种新模式,效果良好,一是解决了粮油争地矛盾。改一年一熟为三熟,小麦产量270kg/667m~2、花生210kg/667m~2、大豆100kg/667m~2,实现了保粮增油。二是提高了经济效益,过去单纯种植一茬粮(玉米)油(花生)作物667m~2产值仅400多元,改种三茬后产值上升到1000元上下,实现了
Funing County is located in northeastern Hebei Province. The local ≥ 0 ℃ accumulated temperature of 4163 ℃, ≥ 10 ℃ accumulated temperature of 3795 ℃, frost-free day of 174 days in the cropping area belongs to the spring grain and spring peanut-cooked area. Seriously in the actual production of grain and oil disputes and simply planting a crop of crop economic problems of low efficiency. Wheat, peanut, soybean crop three interplanting new model, the effect is good, one is to solve the conflicts between grain and oil. One year to change the cooked three crops, wheat yield 270kg / 667m ~ 2, 210kg / 667m ~ 2 peanuts, soybeans 100kg / 667m ~ 2, achieved a grain of oil. The second is to improve economic efficiency. In the past, the output value of 667m ~ 2 crop of simple crop (corn) oil (peanut) oil crop was only 400 yuan, and the output value increased to 1,000 yuan
