我县位于胶东东部,是个丘陵山区。土薄耕层浅,水浇条件差。全年无霜期190天。几年来,在县委领导下,深入开展农业学大寨运动,大搞农田基本建设,实行科学种田,采用挖抗旱丰产沟的方法,实行花生或甘薯与玉米间作,大大提高了粮食和花生的产量,为发展粮油生产闯出了一条新路。怎样挖丰产沟?所谓抗旱丰产沟,是每隔7—10米,南北向挖一条宽1.5—2尺、深1.5—1.8尺的沟,沟面低于地平面6寸左右,沟内种2行玉米,沟之间种花生或甘薯(图)。抗旱丰产沟在丘陵山地或平地都可以挖,但以山丘梯田的增产效果为最显著。
My county is located in eastern Shandong, is a hilly mountain. Shallow tillage, poor water conditions. Frost-free period throughout the year 190 days. In the past few years, under the leadership of the county Party committee, the Dazhai Agriculture Campaign has been intensively carried out. Basic farmland construction has been vigorously carried out. Scientific farming has been carried out. The method of digging drought-resistant ditches has been adopted to implement intercropping of peanuts or sweet potatoes with corn, greatly increasing the output of grain and peanuts , For the development of grain and oil production to break a new road. How to dig a ditch? The so-called drought ditches, every 7-10 meters, north-south to dig a 1.5-2 feet wide and 1.5-1.8 feet deep ditch, ditch less than 6 inches above ground level, ditch species 2 Line of corn, ditch between the peanut or sweet potato (Figure). Drought-yielding ditches can be dug in the hilly mountains or plains, but the yield-increasing effect of the terrace terraces is the most significant.
