摘要
微灌小管出流环沟灌溉法是在原有微灌设备基础上实施的一种节水、节能、抗堵塞的局部灌溉方法,增产省工,灌水均匀,对地形适应性强。这种方法是绕树修一深20cm、宽25cm的渗水小环沟,灌水器利用直径为4mm的塑料管与输水毛管连接,将水引入环沟,湿润果树周围的部分土壤,以达到灌溉的目的。
Based on former microirrigation equipments, Irrigation of circle furrow with small pipes from which water outflow is a part irrigation method that can save water and energy, resist blockages, increase outputs, save labors, irrigate evenly and have a good adaptability to the topography. This type is to dig a 20cmdeep 25cmwide permeable circle furrow round a tree. A plastic pipe connecting with gross diversion pipes as irrigator (4cm in diameter) conducts water to the ditch in such way as to moisten a part of soil round a fruit tree and reach the objective of irrigation.
