旱地麦田隧洞渗(洇)灌技术试验

Experiment of Tunnel Permeating Irrigation in Dryland Wheat

根据传统隧道式灌溉经验 ,设计了旱地小麦隧洞渗 (洇 )灌技术。连续两年试验表明 ,每年灌水 5次 ,大旱之年基本可满足小麦生长发育之需要。洞内水渗 (洇 )距离横向 70～ 80cm ,纵向 30～ 50cm ,比地面灌溉节水 58.1%～ 6 5.1% ,小麦增产 4 4.3%～ 177.0 %。

Based on traditional experience,tunnel permeating irrigation for dryland wheat has been designed.The results of successive two year experiment showed that,five irrigations in one year could meet the water requirement for wheat growth in serious drought year;and the lateral width and vertical depth of water permeatibilities are 70～80cm and 30～50cm respectively.The irrigation method could save 58.1%～65.1% water than the normal type and increased type and increased yield 44.3%～177%.
