节水农业关键技术发展趋势及国内外差异分析

该文通过对国内外节水农业现状及发展趋势分析指出,现代节水农业技术是以节水、高效、安全、改善生态环境与可持续发展为目标,在传统的节水农业技术中融入了生物、计算机模拟、电子信息、高分子材料等一系列高新技术,具有多学科相互交叉、各种单项技术互相渗透的明显特征.该文从灌溉节水技术、节水种植制度、覆盖农业节水技术、抗旱节水作物品种的选育、节水制剂与材料、水肥信息采集技术与预警系统等方面分析了国内外存在的差异.我国节水农业已开展了一系列的技术创新与应用研究,取得了瞩目的成就,但与节水技术先进国家相比仍然存在较大差距.

TREND AND DIFFERENCE FOR DEVELOPMENT ON KEY TECHNOLOGY OF AGRICULTURAL WATER-AVING IN CHINA AND DEVELOPED COUNTRIES

This paper analised and summarized the research and development trend for the agricultural key water -saving technology, pointed out that the goal of the modernized agriculture water-saving technology is water -saving , high- efficiency, security, entironment protection and sustainable agriculture . It is the result of combing the traditional agriculture water saving technology with biology, computer simulation, electronic information, and high polymer material etc. , technology with the characteristic of inter- overlap among many courses of study and inter- infiltration among each single technology. Although the great achievements have been made in China,there is still great distence between China and moernized countries in agricultural key watersaving technology .
