摘要
采用系统分析方法,以张掖市甘州区为例,对典型绿洲灌区种植业结构的现状和发展进行了分析,提出了基于传统节水农业技术体系和高新节水技术体系的优化节水型种植业结构。构建了以优化作物灌溉制度,压粮扩经,强化饲料作物生产,加强带田生产技术研发和应用,以种子和蔬菜产业为突破口,实现节水与增效目标的种植业结构优化对策。表4,参6。
System analysis method was used to develop an optimum agricultural structure for oasis irrigation area in this paper. Based on analyzing the current status and developing tendency of the agricultural structure in a typical oasis irrigation area, two kinds of water-saving agricultural structures were proposed according to traditional water-saving techniques and high-tech water-saving practices respectively. Crop irrigation system was optimized, strategies like decreasing the plant area of the cereal crops while increasing the area of cash crops and forage crops, intensifying the development and adoption of intercropping, and taking the production of vegetables and seeds as a breakthrough, and improving agricultural profit.
