棉花是南疆地区的最主要经济作物，主要采用膜下滴灌的方式进行灌溉。近几年，为了降低灌溉管理的劳动强度，提高灌溉水肥的利用效率，在南疆农一师一团建设了一套基于两线解码器的智能灌溉控制系统。经过两年的应用实践表明，与传统的人工控制方式相比，基于两线解码器通讯的智能灌溉控制系统具有节水、省时、省工、省力等诸多优势。同时，与基于zigbee的无线灌溉控制系统相比，两线解码器运行更为稳定、可靠。综合而言，两线解码器系统是新疆棉花膜下滴灌的较为适宜的自动控制模式。%Cotton is the primary economic crop in the southern Xinjiang, China. Currently, most of the cotton fields in this area is mainly irrigated through dripping systems under the plastic film. In recent years, to further increase the water and fertilizer application efficiency, and to reduce the labor cost of irrigation system management, a computer control ed intel igent irrigation management system is set up in cotton farmland of Xinjiang, which is based on two-wire decoder signal transmission. After two years operation, it showed that the computer control ed intel igent irrigation management system has advantages such as water saving, time saving, and relatively lower labor requirements compared with traditional manual y irrigation system. In addition, the two-wire decoder signal transmission system is more stable than radio signal automation system. It is concluded that the two-wire decoder system is the most suitable automation control measure for the cotton drip irrigation system in Xinjiang.
