滴灌是目前干旱缺水地区最有效的节水灌溉工程形式之一,灌溉水的利用率可达95%。较喷灌具有更高的节水增产效果,同时结合施肥,可以提高肥效一倍以上。水资源日趋紧张的严峻形式下,确保我省粮食产量持续稳定,保障国家粮食安全,大力推广大田滴灌势在必行。
Drip irrigation is one of the most effective forms of water-saving irrigation in drought and water shortage areas. The utilization rate of irrigation water can reach 95%. Compared with sprinkler irrigation has a higher water yield, combined with fertilization, fertilizer can increase more than doubled. Water resources are increasingly tense under the austere form of ensuring that the province’s grain production continued steady, to ensure national food security, vigorously promote the field drip irrigation imperative.
