改造高灌为喷灌,经过在几个点上的试验,效果较好. 高灌是将水送上山顶蓄水池,然后让水从高处流下来灌溉农田,送水上山的输水管从田间通过但不浇地,从渠道流下来的水又往往造成水土流失.改造高灌为喷灌,可以作到一管两用,既能上水,又能喷灌,花钱少,见效快.根据地形情况,可采用自压喷灌或一般喷灌.变高灌为喷灌的好处是:①扩大浇地面积;②节省动力和主管道及其工程投资;③节约用
Transforming high-irrigation for sprinkler irrigation, after several tests, the effect is better.High irrigation is the water sent to the top of the reservoir, and then let the water flow down from high to irrigate the farmland, water pipe up the mountain from the field through But not irrigated, the water flowing down from the channel often causes water and soil loss.Improving high irrigation is sprinkling irrigation, which can be used in one pipe and can be used both for watering and irrigation, , Can be self-pressure sprinkler irrigation or general sprinkler irrigation.Rapid irrigation for irrigation benefits are: ① to expand the irrigated area; ② save power and the main pipeline and its project investment; ③ save
