地面灌溉是最古老、最传统的灌水方法,它与先进的喷灌、滴灌、微灌等方法相比较,存在灌水定额大、灌溉水的利用率低、土壤结构易破坏,用工多等缺点。随社会的发展,其终将被取代,但就目前国情而言,由于传统灌水观念的影响以及地面灌投资小、管理费用低、易操作等,故在未来的很长一段时间里,还将是灌水方式的主题。为了提高地面灌水技术,必须从几方面进行考虑。
Ground irrigation is the oldest and most traditional irrigation method. Compared with advanced irrigation, drip irrigation and micro-irrigation methods, surface irrigation has the disadvantages of large irrigation quota, low utilization rate of irrigation water, easily damaged soil structure and many labor. With the development of society, it will eventually be replaced. However, given the current situation, due to the impact of traditional irrigation concepts and the small investment in land management, the management fee is low and the operation is easy. Therefore, for a long time to come, Is the theme of irrigation methods. In order to improve the surface irrigation technology, we must consider from several aspects.
