目前,大田作物的灌溉方式以管灌、渠灌为主,其中渠灌仍占有很大比重。管灌与渠灌相比,虽然在节水上迈出了重要一步,但仅是提高了渠系水利用率,而田间水利用率并无大的提高。固定式喷灌与管灌相比,虽然节水效果有很大提高,但由于与传统的耕作方式不协调,不能大面积推广。半固定式、移动式喷灌由于操作、管理不便,也很难大面积应用。为此,现结合卷盘式喷灌机的特点探讨了喷灌系统规划设计。
At present, the irrigation methods of field crops are pipe irrigation and canal irrigation, of which canal irrigation still occupies a large proportion. Compared with canal irrigation, irrigation and canal irrigation have taken an important step in saving water, but only increased the utilization rate of canal system water, while there is no big increase in field water utilization rate. Compared with pipe irrigation, fixed sprinkler irrigation greatly improves the water saving effect, but it can not be popularized in a large area because of incompatible with the traditional farming methods. Semi-fixed, mobile sprinkler due to operation, management inconvenience, it is difficult to large-scale application. Therefore, the design of sprinkler irrigation system is discussed with the characteristics of the reel-type irrigation machine.
