省东旱塬蒲城、澄城、合阳一带是陕西重要粮棉产区,麦田占耕地面积50%左右,棉田占10～30%,地广土厚,生产潜力很大。唯因经常出现旱情,尤其近几年来,年降水量多小于500毫米,伏旱强度大,严重影响粮棉的稳产高产。1974年,在批林批孔运动推动下,农业学大寨运动深入发展,虽遇严重春伏旱,仍夺得了较好收成.合阳县大伏六人队小麦单产一季上《纲要》,亩产412斤,澄城县埝村大队小麦亩产264斤,均为历史最高水平。深厚的土体相当于一个蓄水库,通过学习群众抗旱增产经验,了解有关土 Pucheng, Chengcheng, and Heyang in the eastern Hanban Plateau are important grain and cotton producing areas in Shaanxi Province. Wheat fields account for about 50% of the cultivated land area and cotton fields account for 10% to 30%. Due to the frequent drought, especially in recent years, the annual precipitation more than 500 mm, the intensity of drought, seriously affecting the stable yield and high yield of grain and cotton. In 1974, thanks to the campaign of criticizing Lin and Kong dynasties, the Dazhai Campaign in Agriculture was further developed, and despite the severe spring drought, it still won a good harvest. Producing 412 pounds, Chengcheng County Qiongcun brigade wheat yield 264 pounds, are the highest level in history. Deep soil is equivalent to a reservoir, learning drought relief by increasing production experience to understand the soil
