近年来,随着农业生产的不断发展,在作物灌溉方面除了原有的畦灌、沟灌、喷灌和滴灌外,又出现了地面管道灌水、地下渗灌和空中喷雾灌溉等几种新的灌水方法。一、地上移动式管道灌溉地上移动式管道灌溉原先是根据抗旱灌溉的需要而采用的灌水方法,适用于平原及丘陵地区大面积的农田灌溉。管材一般是用塑料薄膜软管,也可以用硬质塑料管、维尼龙软管或消防水带管。进行灌溉时将管子的一端连在水泵的出水口上(即“对口抽”),另一端则延伸到农田畦子的远端(也可以不打
In recent years, along with the continuous development of agricultural production, in addition to the original irrigation, furrow irrigation, sprinkler irrigation and drip irrigation in crop irrigation, several new irrigation methods such as ground pipe irrigation, underground infiltration irrigation and air spray irrigation have emerged. First, the mobile ground irrigation Pipeline irrigation was originally based on the needs of drought irrigation irrigation method used for large areas of plain and hilly areas of farmland irrigation. Plastic pipe is generally used plastic hose, you can also use rigid plastic pipe, vinylon hose or fire hose. For irrigation, connect one end of the tube to the water outlet of the pump (ie “pump”) and the other end to the far side of the farmland
