为了挖掘土地生产力,提高单位面积上的经济效益,我们运用农业工程学原理,结合当地生产实际,设计了若干农田栽培工程模式,经过二三年实践检验,经济效益十分明显,广大农民乐于接受。1986年全区推广17万亩,每亩产值平均为727.5元,最高达1510元,最低为520元。由于运城地区地处山西省最南部,光热资源丰富(0℃以上积温5118.3℃),无霜期长(203—236天),水肥条件好,推广复种或间、套、栽种农田,有着得天独厚的自然条件,只要设计科学,安排合理,就能创造良好的经济效益,增加农民收入。运城地区主产小麦、棉花,全区920万亩耕地,常年种植小麦540万亩,棉花200万亩,仅此二项占耕地80.4％,因而,高效益农田设计,一般以麦田和棉田为主。主要形式介绍如下:
In order to excavate land productivity and increase the economic benefits per unit area, we have used agricultural engineering principles and local production practices to design a number of farmland cultivation engineering models. After two or three years of practice, the economic benefits are obvious and the majority of farmers are happy to accept them. In 1986, the whole region promoted 170,000 mu, with an average output value of 727.5 yuan per mu, up to 1,510 yuan and a minimum of 520 yuan. As the Yuncheng area is located in the southernmost part of Shanxi Province, it is rich in light and heat resources (5118.3 ℃ accumulated temperature above 0 ℃), long frost-free period (203-236 days), good water and fertilizer conditions, promotion of multiple cropping or planting, farmland cultivation, Conditions, as long as scientific design, reasonable arrangements, we can create good economic returns and increase farmers’ income. The main production of wheat and cotton in Yuncheng area covers 920 million mu of cultivated land in the whole region. The annual planting of wheat is 540 million mu and 200 million mu of cotton. Only the two items occupy 80.4% of the cultivated land. Therefore, the design of high-efficiency farmland is mainly dominated by wheat fields and cotton fields . The main form is as follows:
