摘要
通过大田枸杞滴灌和传统畦灌对照处理试验,研究了覆膜滴灌下枸杞耗水规律、水分利用效率和产量的变化规律,结果表明,枸杞覆膜滴灌生育期内耗水量相比传统畦灌平均减少了34%,生育期内灌溉定额相比传统畦灌平均节约了52%。当覆膜滴灌枸杞耗水量为612 mm时,枸杞的水分效率和干果产量达到最优组合水平。
The ETc, water use efficiency and yield variation of Chinese wolfberry were studied through field drip irrigation and border irrigation. The result shows that the ET~ of Chinese wolfberry under mulch drip irrigation is reduced by 34 % on average compared with the traditional border irrigation, and saving 52 % of irrigation quota compared with the traditional border irrigation. When the ETc of Chinese wolfberry under mulch drip irrigation is about 612 mm, the water efficiency and dried fruit production of Chinese wolfberry reach the optimal combined levels.
