滴灌,是近年来发展起来的一种较先进的灌水技术。它是利用一套设备将水以点滴的方式,缓慢地、一滴一滴地送到作物根系最发达的区域,只湿润部分土层和表土,使作物根系附近的土壤水分保持在最合适的含量,这就改变了地面灌溉存在的土壤水分含量有时过多,有时过少的现象,有利于作物的生长和发育。滴灌较适用于干旱缺水的丘陵山区和沙漠地带。它的特点灶:省水(20～50%),省工,增产(据对比
Drip irrigation, developed in recent years, a more advanced irrigation technology. It uses a set of equipment to trickle down the water slowly and drop by drop to the most developed area of the crop root. Only wetting some soil layers and topsoil, the soil moisture in the vicinity of the crop root is kept at the most suitable level, This has changed the sometimes excessive and sometimes too little soil moisture content of surface irrigation, which is conducive to crop growth and development. Drip irrigation is more suitable for drought and watery hills and desert areas. Its characteristics stove: saving water (20 ~ 50%), labor, increase production (according to contrast
