晋南是山西主要棉麦产区,现有耕地中低产田占很大的比例(50％左右),所以提高低产田的生产水平和经济效益就成为提高农业总产量和总效益的关键问题。根据物质守恒定律,单纯依靠低产田自身的物质循环,很难达到农作物高产优质。故我们于1988～1990年连续三年在山西省永济县于乡,省劳改局农牧研究所低产田中播置了小麦肥料用量的试验,探讨提高低产田肥力以达到小麦高产优质和提高施肥效益的合理施肥措施。

Jinnan is a major cotton and wheat producing area in Shanxi. Currently, a large proportion (about 50%) of middle and low-yield farmland is under cultivation. Therefore, raising the production level and economic benefits of low-yielding fields has become a key issue to increase total agricultural output and total benefits. According to the law of conservation of matter, it is hard to achieve the high yield and quality of crops simply by relying on the material circulation of low-yield fields. Therefore, in 1988 ~ 1990 for three consecutive years in Yongji County, Shanxi Province, Township, Provincial Bureau of Agriculture and Animal Husbandry Institute of low-yield field of wheat fertilizer trial broadcast to explore ways to improve low yield fertility in wheat to achieve high yield and quality of wheat and improve fertilization Effective fertilization measures.
