山西省在第一个五年計划期間,粮食总产量一直是在70至90亿斤之間搖摆不前,从未突破百亿斤的大关。在全省6,800万亩耕地中,有半数(3,560万亩)是坡耕地。这些坡耕地中有2,300万亩亩产量在100斤以下,人們称之为“低产区”。因此改变占全省耕地三分之一的低产区为高产区,就成为全省农業增产中的关键問題了。这个低产区分布在雁門关以北和山西省西部、西北部黄河沿岸地区,共有33个县。其特点是:地广人稀、水土流失严重,輪垦陡坡、开荒到頂、劳力不足,畜力困难,三料(肥料、燃料、飼料)俱缺,耕作粗放,地力瘠薄,广种薄收,單一經济,人民生活貧困。如平鲁县共有耕地102万亩,每人平均耕地12
During the first five-year plan of Shanxi Province, the total grain output has been staggering between 7 and 9 billion jin and never exceeded the mark of 10 billion jin. Half of the 68 million mu of arable land in the province (35.6 million mu) is sloping land. There are 2,300 mu of mu yield in these slopes of cultivated land below 100 kg, which people call “low-yield areas.” Therefore, changing the low-yielding area, which occupies one third of the cultivated land in the province, into a high-yielding area has become a key issue in the province’s agricultural production increase. The low-yielding areas are located in the north of Yanmen Pass and west of Shanxi Province, the Yellow River northwest of the region, a total of 33 counties. Its features are: sparsely populated, soil erosion is serious, Rotary reclamation steep slopes, land reclamation to the top, lack of labor, animal husbandry difficulties, three materials (fertilizers, fuel, feed) deficiency, extensive farming, infertility, a variety of thin income, single economy, people Living in poverty. For example, Pinglu County has a total of 1.02 million mu of arable land, with an average of 12 per mu
