利用风力进行提水灌溉已有较久的历史。目前,盐城县大纵湖公社是使用风车提水最多的一个公社。通过调查,发现使用风力提水机具有不能保证稻田用水的需要,实际投资大,吨水成本高,年利用率低等问题,得出不宜在水稻地区发展风力提水机具的意见。一、风力提水机具的使用情况大纵湖公社地处盐城县西南,属水稻产区。该社共3万人口,3万亩耕地。耕地都是开垦草滩而来,因此虽属粘土,稻田有如沙壤土的渗水现象,需要经常补水。在3万亩耕地中,一熟制水稻田为144亩,稻麦两熟有26322亩,其余
It has been a long time since irrigation was carried out using wind power. At present, Yancheng Dahonghu commune is the commune that uses windmills to lift water most. Through the investigation, it was found that the use of the wind-powered water-purifier can not guarantee the water demand of the paddy field, the actual investment is large, the cost per ton of water is high, and the annual utilization rate is low. First, the use of wind lifting equipment Dazhong Lake commune is located in Yancheng County, southwest, is a rice-producing areas. The community a total of 30,000 people, 30000 acres of arable land. Cultivated land is reclaimed from the beach, so although it is clay, paddy fields like sand loam seepage phenomenon, the need for regular replenishment. Among the 30,000 mu of cultivated land, there are 144,300 mu of paddy field and 26,322 mu of paddy and wheat. The rest
