1 集雨自压节灌试点的科学尝试1.1 工程的建设情况拐沟试点工程主要集纳北横岭山坡上的雨水,利用自然高差,用管道将水送入集雨水窖进行自压灌溉。现已完成:①积雨工程:利用北横岭雨水汇集的“五萝井”水和70年代修建的积蓄山坡雨水3000m~3水池,集雨面积24hm~2。②输水工程:铺设、安装各种塑料管5000多米,将水输送到每个水
1 rainwater harvesting self-pressure pilot project of scientific experimentation 1.1 Construction of the project The main project of the trenching pilot project is to absorb the rainwater on the northern ridge of Hengshan and make use of natural height difference to send the water to the catchment cellar for self-pressure irrigation by pipeline. It has been completed: ①Catch rain project: use “Five Lotus” water collected by the rainstorms of North Hengling and 3000m ~ 3 pool of rainwater on the hillside built in the 1970s, collecting rain area of 24hm ~ 2. ② water projects: laying, installing more than 5,000 meters of plastic pipe, the water delivered to each water
