自压滴灌技术在农田灌溉中的应用与研究

Research and application of self-pressure drip irrigation technology in farmland irrigation

我国是农业大国,每年用于农业的灌溉用水约占全国总供水量的60%,因此合理应用灌溉技术,提高水资源的利用率,是推动我国农业现代化发展的关键。自压滴灌技术是把自然环境中的重力落差作为农业灌溉用水的动力,将灌溉用水通过设施过滤分流后输送到土壤之中,具有节约用水、节约肥料、节约人力、应用成本低等优势,尤其适用于干旱地区、丘陵山区的农田灌溉。通过分析自压滴灌技术的优势,提出从做好引水渠道、压力前池、首部枢纽、水配水管网等关键要素的设计和规划入手,充分发挥该技术的应用优势,有效提高农田灌溉的效率和水资源的综合利用率。

China is a largely agricultural country,and the annual irrigation water used for agriculture accounts for about 60%of the total water supply in the country.Therefore,the rational application of irrigation technology and improving the utilization rate of water resources is the key to promoting the development of agricultural modernization in China.Self-pressure drip irrigation technology uses the gravity drop in the natural environment as the driving force for agricultural irrigation water,which is filtered and diverted through facilities before being transported to the soil.It has the advantages of saving water,fertilizer,manpower,and low application costs,and is particularly suitable for agricultural irrigation in arid areas and hilly and mountainous areas.Through the analysis of the advantages of self-pressure drip irrigation technology,the design and planning of key elements such as water diversion channel,pressure response,head hub and water distribution pipe network are proposed.This scheme can give full play to the application advantages of this technology and effectively improve the working efficiency of farmland irrigation and the comprehensive utilization rate of water resources.
