当今国内外地面灌溉仍是最普遍采用的灌水方式,因此改善地面灌水技术是提高田间灌水质量、节约灌溉水量的重要举措.作为80年代逐渐发展起来的先进地面灌水技术,波涌灌溉方法具有田间水利用效率高、灌水均匀度好的特点,但其在我国的实际应用有赖于适合国情的波涌灌溉设备的开发问世.结合国家“九五”科技攻关项目研制的波涌灌设备具有一阔多用、操作简便的特点.田间考核结果表明,这套设备已达到原设计要求和较佳性能指标,具有较强的实用性和推广应用前景.
At present, surface irrigation at home and abroad is still the most commonly used method of irrigation. Therefore, improving ground irrigation technology is an important measure to improve the quality of irrigation and save irrigation water. As an advanced ground irrigation technology gradually developed in the 1980s, the surge irrigation method has the characteristics of high field water use efficiency and good irrigation uniformity, but its practical application in our country depends on the development of surge irrigation equipment suitable for the national conditions. Combined with the national “Ninth Five” scientific and technological project developed surge irrigation equipment has a wide range of uses, easy to operate features. Field assessment results show that this set of equipment has reached the original design requirements and better performance indicators, with strong practicality and promote the use of the future.
