Water-saving irrigation is an important part of the modernization of agriculture, the development of water-saving irrigation, water efficiency is the only way to achieve modernization. China's situation: on the one hand, a serious shortage of water resources, on the other hand the low utilization of agricultural irrigation water, waste is very serious. China's long-term agricultural irrigation in use primitive methods of irrigation, water saving space. Water-saving irrigation according to crop water requirement and the local water supply conditions, a variety of measures taken in order to make effective use of rainfall and irrigation water, and access to the best agricultural economic, social, ecological environmental benefits, the general term. Irrigation water from the source to the field to go through several links, each link is there water useless loss. All these links can reduce the amount of water loss, improve irrigation water use efficiency and economic benefits of various measures, belong to the category of water-saving irrigation. Water-saving irrigation measures are the following: (1) reasonable development and utilization of water resources, (2) reduce channel water losses. (3) the use of water-saving irrigation methods and techniques. (4) agronomic water-saving technologies that from the crop itself seek water-saving methods. (5) to improve the level of water management. sprinkler technology is one of the water-saving irrigation methods, pressurized water, the use of specialized equipment or the use of the natural drop of water will have a pressurized water to the irrigation lots through the sprinkler spray into the air to form water droplets sprayed onto crops and field irrigation methods like rain. Sprinkler irrigation not only meet the conservation needs of urban green spaces and sports turf add a beautiful landscape, but also for the people's living environment. This method has a water-saving, increase production, save labor, land, soil conservation, fertilizer, adaptable and comprehensive utilization of advantages. Electric pivots sprinkler irrigation technique used in sprinkler irrigation equipment, electric irrigation system, the roll shift irrigation machine, winding irrigation machine. This article is mainly developed for winding irrigation machine. Winding irrigation machine in the early 1970s in the the shift pipe sprinkler system on the basis of development, is a compact, easy to move, fewer operating personnel and can automatically walk sprinkler irrigation equipment for spraying operations. Winding irrigation machine nozzle car, hose, hydraulic drive machine and reel cars and other parts. Sprinkler operating time, the hose is pulled Shop on the ground are filling, the rotating winding hose reel sprinkler pressure water drive, traction nozzle slowly toward the reel and spraying operations. Where the hose is special in density polyethylene black half-hose, high pressure resistance, drag, resistance to bending characteristics. The service life of up to 10 years of this irrigation machine, easy to operate, can be automated to run, only 1-2 people management. Can work day and night, every day just to move one or two, once just over 20 minutes to install. Each irrigation machine control 3.50hm ~ 2 land. Can be adapted to different regions, crops, soil and water. Irrigation ground without any engineering facilities are not subject to the influence of the field, trees, utility poles and other obstacles, as long as there is water, connected to the pressure of the water can move the sprinkler, irrigation finished the whole storage custody. Based on these advantages, further illustrate the need for developed winding irrigation machine.
