摘要
微喷带是在滴灌与喷灌方式的基础上发展起来的灌溉设备,为了研究其在建平县等半干旱地区的应用效果,开展了微喷带灌溉、膜下滴灌、漫灌3种方式的对比试验。结果表明,微喷带灌溉与膜下滴灌、漫灌相比分别节水16.7%、66.7%,灌水次数比漫灌少50%;微喷带灌溉及膜下滴灌均在一定程度上抑制了玉米的营养生长,但其产量比漫灌方式高。由此可知,该技术可以在建平县及其他相似地区推广。
Micro-spraying hose irrigation is developed on the basis of drip irrigation and sprinkler irrigation,in order to study the application effect in the semi arid area such as Jianping County,the comparative test were carried out in 3 ways of microspray irrigation,drip irrigation under mulch film and flood irrigation.The result showed that microspray irrigation save 16.7%、66.7% water of drip irrigation and flood irrigation,reduced 50% irrigation times of flood irrigation,micro-spraying hose and drip irrigation under mulch film inhibited the growth of maize in a certain extent,but the yield was higher than flood irrigation.Thus,the technology can be popularized in Jianping County and other similar areas.
