在农业灌溉中,有“漫灌”、“喷灌”和“滴灌”三种浇灌方式。同样是灌溉,投入与产出是绝不相同的:“漫灌”是一种粗放的地面灌溉,任水漫流下渗,水量浪费大而收效微;“喷灌”是将水喷射至空中,以雨滴状态散落田间的一种方法,它是针对大面积作物的定时灌溉,相对而言,既节约收效也高;“滴灌”是利用管道等设备,使灌溉水缓缓滴出,浸润作物根系的一种灌溉方法,它从根本上改变了传统耕耘观念,使每一滴水都派上了用场,真正做到了节能而高效。
In agricultural irrigation, there are three types of watering methods: “deep irrigation,” “spray irrigation,” and “drip irrigation.” In the same way, irrigation is different from input and output: “Rain irrigation” is a kind of extensive surface irrigation, where any water is infiltrated, water is wasted and the effect is small; “sprinkling” is spraying water into the sky and falling in raindrops. A method in the field, which is aimed at the regular irrigation of large-scale crops. Relatively speaking, it saves both efficiency and efficiency; “drip irrigation” is the use of pipelines and other equipment to slowly drip irrigation water and infiltrate the roots of crops. Method, it fundamentally changed the concept of traditional cultivation, so that every drop of water came in handy, truly energy-efficient and efficient.
