晋西北土地资源利用研究

Land Resources Utilization in the Northwest of Shanxi Province

晋西北地区在山西省人均耕地资源丰富,但是受到低温、干旱、坡度大的为害,农业生产广种薄收。通过调查研究,认为晋西北农业生产应该注意以下几点:①在土地利用结构调整中,建设坡耕地退耕种草、饲料玉米、豆科杂粮和抗寒果树的4类用地结构;②在农业生产中,促进生产的机械化、集约化和产业化水平;③加大地膜覆盖推广力度,尤其是宽幅地膜的推广、增施化肥和有机肥、引进良种、农田保护性耕作与粮草轮作技术和病虫害防治等5大类实用农业技术。

The Northwest of Shanxi Province is rich in capitation land resources, However, limited by the low temperature, drought and steep slope of land, crop yield in the region is very low. This paper presented some approaches to develop agriculture there. ①Adjusting land use structure, using slope land as grassland in stead of cropland, constructing forage maize, bean and grain field or cold-hardiness fruit tree orchard; ②Promoting mechanization, intensive cultivation and industrialization; ③ Popularizing plastic mulching, especially wide mulching plastic cover, increasing fertilizer and organic matter, in addition, introducing improved variety and other agricultural technologies, such as protective cultivation and grass-croprotation, the defense and controlling of pest and disease, so on.
