摘　　要：在中国农业现代化建设中,影响农业资源可持续发展的主要因素是土、种、肥、药、水。精准耕整技术、精准播种技术、精准施肥技术、精准施药技术和精准灌溉技术是提高农业资源利用率的几项关键技术。提高农业机械化水平,是促进农业资源可持续发展的重要途径之一。该文介绍了提高农业资源利用率的机械化精准作业关键技术与机具。为了进一步发挥农业机械化在提高农业资源利用率、促进农业可持续发展中的作用,该文建议:进一步加强农机农艺融合,加强相关基础理论研究;进一步加强相关关键技术的研究;进一步加强相关机械与装备制造的自主创新能力;进一步加强推广应用。Although great development has taken place in agricultural mechanization since reform and opening up, China still faces the big challenge in improving agricultural resource utilization as well as promoting the sustainable development of agriculture at present. As we all know, it is mainly the 5 factors, i.e. water, soil, fertilizer, pesticide and seed that affect sustainable development in the construction of China＇s agricultural modernization. The overall development of agriculture in China will be impeded if the resource utilization stays low. There exist some phenomena： 1） the irrigation water use is 360 billion m3 each year, while canal-system water use efficiency is only 0.4~0.6; 2） high-quality cultivated land is lacking; 3）nitrogen use efficiency is about 30%~35%, which is 20% less than developed country; 4） pesticide utilization is merely about30%, while leads to severe environmental pollution; 5） the demand of seeding quantity is high while there are shortage of high-quality seeds and serious waste of seeds. Accordingly, several technologies and machines in PA（precision agriculture）were put forward in this article so as to meet the requirement of agricultural sustainable development： precision irrigation,precision plow, precision fertilization, precision spraying, and precision sowing. By reviewing the researches at home and abroad, the current situation of PA was analyzed and thus the methods to achieve the 5 mentioned key technologies were presented. Meanwhile, some other suggestions were proposed to push the agricultural mechanization to play a greater and more important role on the utilization of agricultural resource and agricultural sustainable development： 1） further strengthen the combination of agricultural machinery and agronomy as well as the basic study of related theory; 2） carry out in-depth studies on key technologies of maximum utilization of agricultural resource, especially in precision irrigation,precision plow, precision fertilization, precision spraying, and
