为了给高寒阴湿山区发展高产高效种植业提供示范推广的种植形式,我们在和政县卜家庄乡拉力洼村(海拔2250～2400m)进行了地膜玉米与麦、油、豆、菜作物的复合带田试验示范,通过三年来的种植示范,在缺磷少氮的黑麻土地上亩施硝铵60kg,过磷酸钙25kg,农肥5000kg的投入水平下,混合亩产平均达499.1～634.9kg,比单种地膜玉米亩增产粮71～206.8kg,亩增收77～410元。比全乡单种粮食平均亩增383.3kg,比本村单种粮食平均亩增
In order to provide demonstration and popularization of cultivation for the development of high-yield and high-efficiency planting in the alpine and humid mountainous areas, we conducted the experiment of mulching corn and wheat, oil, beans and vegetable crops in Laluwa Village (2250 ~ 2400m above sea level) in Bujiazhuang, Hezheng County In the past three years of demonstration, the average yield of mixed mu produce reached 499.1 ~ 634.9kg per mu under the input level of 60kg of ammonium nitrate, 25kg of superphosphate and 5000kg of fertilizer. , Which is 71 ~ 206.8kg more than the single mulberry mu. The mu income increased by 77 ~ 410 yuan. An average of 383.3kg more than the average grain output of the single township, an average increase over the single grain of the village
