| 农田喷灌设备的使用 Use of Sprinkler Irrigation Equipment in Farmland 使用农田喷灌设备时，要根据灌溉的地形、灌溉面积的大小、作物的品种、不同生长期的不同需水量等因素，合理选择喷灌机组和喷头，正确安装和调整，正确使用和保养动力机械和水泵，保证作业质量。 When using farmland sprinkler irrigation equipment, we should reasonably select sprinkler irrigation units and sprinkler heads, install and adjust them correctly, use and maintain power machinery and pumps correctly according to the factors such as irrigation topography, irrigation area, crop varieties and different water demand in different growth periods, and so on, so as to ensure the quality of operation. 1、管路系统的布置 1. Layout of Pipeline System 布置管路系统时，一定要综合考虑现有水利系统、水源的位置、地势、地形、主要的风向、风速、作物的布局和耕作的方向等因素，在经济和技术上进行全面比较和权衡，选出最优方案。 When arranging pipeline system, we must comprehensively consider the existing water conservancy system, water source location, topography, main wind direction, wind speed, crop layout and tillage direction and other factors, and make a comprehensive comparison and balance in economy and technology to select the optimal scheme. 2、喷头的配置 2. Configuration of nozzles 喷头配置的位置直接影响到喷洒质量，配置时各喷头的喷洒面积与邻近喷头的喷洒面积必须有一定的重叠量，以防漏喷。喷洒方式一般采用全圆喷洒，其特点是喷头间距大，喷灌强度低；由于风力的影响、水土保持的要求、地边地角喷洒需要、移动机组的行走道路等因素，有时也采用扇形喷洒。定点喷灌的喷头配置组合原则是，保证喷洒不留空白，并有较高均匀度。 The position of sprinkler configuration directly affects the spraying quality. The spraying area of each www.hupomoju.cn www.lujianbanmoju.cn www.paomoqiegeji.com.cn www.lianjieqi.org.cn www.baowenganggua.cn www.duihanfalan.com.cnsprinkler must overlap with the spraying area of adjacent sprinklers in order to prevent leakage. Full circle spraying is generally adopted, which is characterized by large distance between sprinklers and low intensity of sprinkler irrigation. Fan spraying is sometimes used because of the influence of wind, the requirements of soil and water conservation, the need of spraying at the edge and corner, and the walking road of mobile units. The combination principle of sprinkler configuration for fixed-point sprinkler irrigation is to ensure that no blank is left in the sprinkler and that the sprinkler has a high uniformity. |
