果树涌泉灌溉方式的技术应用

涌泉灌又称小管出流.涌泉灌溉技术是针对滴灌系统使用过程中灌水器容易堵塞,以及农业生产管理水平不高而设计的一种微灌技术.它具有节水、节能、灌水均匀、水肥同步、适应性强、管理方便等优点.经过试用,涌泉灌溉果树一般较传统的地面灌节水50%～70%,增产6%～10%,灌水均匀度在90%以上.该文介绍了涌泉灌溉技术及田间设计要点.

Technology and application of fruit tree bubbler irrigation

Bubbler irrigation is called little pipe current. Bubbler irrigation is one type of the micro-irrigation. It aims directly at apparatus blockade problem of drip-irrigation system in China. Bubbler irrigation has the advantages of saving water and energy, more uniform irrigation, coincidence of water and fertilizer and easy operation, etc. Through application, bubble irrigation fruit tree saved water by 50%~70%, production yield rose by 6%~10%, compared with furrow irrigation. Irrigation uniformity is over 90%. This paper introduces bubbler irrigation technology and main design points.
