摘要
为了探求更加经济节水的保护地蔬菜栽培灌溉技术,应用特殊打孔工艺研制了节点式PE渗灌管。田间灌水性能试验表明,自行研制的渗灌管灌水均匀度达到了90%以上;豇豆试验结果表明,相同的田间管理条件采用节点式渗灌技术的灌水量仅为沟灌用水量的1/3,而每方水豇豆的生产力为沟灌的3.42倍。
In order to search more economical water-saving irrigation technique in greenhouse, a PE-Node Permeation Irrigation pipeline was developed with a special stiletto techniques. Experiment of irrigation capability was carried out in field, the result showed that the uniformity of irrigation is over 90%. Result of cowpea cultivation experiment showed that the water quantity of node permeation irrigation pipeline only accounted for 1/3 of furrow irrigation＇s, and the productivity of cowpea was 3.42 times as much as furrow irrigation＇s.
