陕西省汉中平川一直延续着“油菜+水稻”或“小麦+水稻”两熟农业生产模式,生产成本高、效益差。近几年,青壮年大量外出务工,农村劳动力严重不足,加之农村养殖业效益直线下滑,全民养殖局面一去不复返,农业生产所需的农家肥严重不足,土壤养分缺乏、化肥使用量不断加大、生产成本节节攀高、生产效益匮乏、冬季土地撂荒现象日益严重。针对该地当前农业生产现状,经过多年的探索试验示范,笔者总结出了汉中川道“双膜马铃薯早玉米豆角间作套种高效栽培技术”。该项技术简单易行,可减轻农户的劳动强度、降低生产成本、提高效益、减少冬季撂荒、弥补效益不足、稳定粮油产量。
Hanzhong Pingchuan in Shaanxi Province has inherited the “double cropping” model of “rape + rice” or “wheat + rice” with high production cost and poor efficiency. In recent years, a large number of young and middle-aged migrant workers go abroad, a serious shortage of rural labor, combined with a straight-line decline in rural aquaculture efficiency, the situation of universal farming gone, a serious lack of necessary agricultural production of agricultural production, lack of nutrients in the soil, the use of chemical fertilizers Increase production costs steadily increase, lack of production efficiency, land shortage in winter is worsening. In response to the current status of agricultural production in the area, after years of exploration and demonstration, the author summed up the Hanzhong River Road, “double-film potato early corn intercropping intercropping efficient cultivation techniques.” The technology is simple and easy, can reduce the labor intensity of farmers, reduce production costs, improve efficiency, reduce winter shortage, make up for lack of efficiency, and stabilize grain output.
