我省是全国水资源最少的省份之一,特别是70年代末以来,连年干旱,农业、工业和城镇生活用水日趋紧张,已成为我省国民经济发展的制约因素。农业缺水的严重局面促使我省广大农民从思想认识到生产实践走上了节约用水的必经之路。搞好输水防渗,提高水的利用率,是节约用水的一个重要方面。我省以井灌为主,井灌区的输水防渗是关系到农业生产持续稳步发展的重要课题。 80年代初以来,我省使用塑料管道输水灌溉,效果好、发展快,目前已在平原、沿海区的大部井灌区和局部山丘区得到广泛应用。
Our province is one of the provinces with the least water resources in our country. Especially since the late 1970s, successive years of drought, water use in agriculture, industry and urban areas have become increasingly tense, which has become the limiting factor in the development of our national economy. The serious situation of water shortage in agriculture has prompted the vast number of peasants in our province to embark on the path of water conservation from ideological understanding to production practice. Doing a good job in water seepage prevention and improving water utilization rate is an important aspect of water conservation. Well-irrigation is the main part of our province, well irrigation and drainage seepage control is related to the sustained and steady development of agricultural production an important issue. Since the early 1980s, the use of plastic pipe irrigation in our province has achieved good results and rapid development. At present, it has been widely used in most well irrigation areas and local hills in the plains and the coastal areas.
