不同类型滴灌带灌水均匀度田间试验分析

"十二五"规划中指出发展节水灌溉的同时保证低能耗,为此,低压低能耗的微灌技术将成为未来节水灌溉发展的核心。实验选取了自治区节水灌溉重点县自动化滴灌示范基地中使用较多的两种不同类型滴灌带作为研究对象,分析了不同铺设坡度、铺设长度、入口压力等对滴管带灌水均匀度的影响。结果表明,该自动化滴灌示范基地中采用的两种滴灌带均能满足设计的灌水要求,均匀度良好。从试验结果中还发现A型滴灌带在低压条件下进行灌水均匀度良好,综合分析且在耗能上较B型滴灌带低,能够达到低压低能耗微灌技术的要求。

Field Experiment and Analysis of Irrigation Uniformity of Different Drip Irrigation Tapes

As pointed in Twelfth Five-year Plan,water saving irrigation and low energy consumption should be ensured at the same time.So,the micro-irrigation technology with low pressure and low energy consumption will be the core of water saving irrigation development in the future.Two different types of drip irrigation tapes,which are used frequently in autonomous region key automation drip irrigation demonstration base,are selected as research objects in this experiment to study the effects of different laying slope,length and inlet pressure on the irrigation uniformity of drip irrigation tapes.The results show that both the two kinds of drip irrigation tapes in this automation drip irrigation demonstration base can satisfy the irrigation requirements,and the irrigation uniformity is well.It is also found in this experiment that the irrigation uniformity of A-tape drip irrigation tape is well under low pressure condition,and its energy consumption is lower than that of B-tape.The A-tape can match the requirement of low energy consumption micro-irrigation technique.
