涿鹿县采取传统技术与现代科学相结合的方法,对30万亩丘陵农田实行旱作,使粮食总产连续九年稳定在1.5亿公斤左右。涿鹿县地形复杂,有山区、丘陵、河川,水地、旱地各占一半。近年来,根据“有水搞灌溉,无水靠旱作”的原则因地制宜。在提高水地单产的同时,重点挖掘丘陵旱地的增产潜力。为此,采用了下列旱作农业技术: ——改造坡梁地,建设水平梯田。全县每年结合小流域治理,大搞梯田加工,把跑水、跑土、跑肥的“三跑田”改造为“三保田”,使土壤蓄水抗旱能力和地力得到提高。全县已建成水平梯田达10万亩。——坚持秋耕、深耕、普耕,耕后耙耱、碾压和蓄雪保墒。据测定:凡耙耱碾压的地块,10厘米深 Zhuolu County adopts a combination of traditional techniques and modern science to dry up 300,000 mu of hilly farmland so that the total grain output will be stable at 150 million kilograms for nine consecutive years. Zhuolu County terrain complex, with mountains, hills, rivers, water, dry land each accounted for half. In recent years, according to the principle of “water is irrigated and no water is used for drought”, measures should be taken in accordance with local conditions. In improving water yield at the same time, focus on the hurdles yield potential. To this end, the following dry farming techniques have been adopted: - Reconstruction of slopes, construction of horizontal terraces. The county combined with small watershed management every year, engage in terraced processing, the running water, running the soil, running fertilizer, “Three Kau fields” transformed into “three insured fields” so that soil water resistance and ability to improve drought resistance. The county has built up to 100000 acres of terraces. - Insist on autumn plowing, deep plowing, general farming, raking 耕 after cultivation, rolling and storing snow moisture. It is measured: Where rake 耱 rolling plots, 10 cm deep
