喷灌技术具有省水、省工、省地、增产、调节田间小气候,适应性强等优点。在高扬程提水灌溉或地下水埋藏深的地区,采用喷灌技术在节水的同时还能节能。在小麦产区还可以抵抗干热风的侵害。因此在缺水的干旱半干旱丘陵山区应大力提倡和推广。一、基本情况我市喷灌建设是在1977年和1978年两年 Sprinkler irrigation technology has the advantages of saving water, saving labor, saving land, increasing production, regulating the microclimate in the field, and adaptability. In high-lift irrigation or groundwater buried deep areas, the use of sprinkler irrigation technology, while saving energy. In the wheat-producing areas can also be resistant to dry hot wind violations. Therefore, it is necessary to advocate and popularize in the dry and drought semi-arid hills and mountains. First, the basic situation Sprinkler irrigation construction in 1977 and 1978 two years
