东起吕梁山,西到黄河畔,北至右玉,南抵乡宁,这一狭长地带,是晋西水土流失严重地区。境内28县,面积46200平方公里,约占全省总面积的三分之一。这里因受地形和水文条件所限,适宜发展灌溉的土地很少,历来实行旱作农业。但是,由于大多是坡耕地,水土流失严重,土壤瘠薄,耕作粗放,旱作农业的生产力很低。如何提高该地区旱作农业生产水平,许多专家从各方面进行着广泛的研究。本文想就水土保持治理与旱作农业的有关方面谈几点粗浅的看法。
Lvliangshan from the east, west to the Yellow River, north to right Jade, south Ningxiang, this strip of land, is a serious water and soil loss areas in western Shanxi. The territory of 28 counties, an area of 46200 square kilometers, accounting for about one-third of the total area of the province. Because of the limited terrain and hydrological conditions here, there is very little land suitable for irrigation and dry farming has always been practiced. However, due to mostly sloping fields, soil erosion is serious, the soil is infertile and extensive farming, the productivity of dry farming is very low. How to improve the level of dry farming in the area? Many experts conduct extensive research in all fields. This article would like to talk about the soil and water conservation and dry farming related aspects of a few superficial views.
