极端干旱地区滴灌条件下葡萄生长发育特征

    Characteristics of grape growth under drip irrigation condition in extremely arid regions

    • 摘要: 不同滴灌布设方式下,土壤含水率不尽相同,作物的长势和产量也因此受到影响。为探究滴灌管道布置方式和系统技术参数对葡萄植株生长发育特性和产量的影响,并优选出适合吐哈盆地的葡萄滴灌技术参数,该文对不同滴灌技术下土壤含水率以及成熟期葡萄植株生理指标进行观测和分析,结果表明:地面滴灌3管布置、滴头流量2.7 L/h、滴头间距30 cm的处理达到了最优效果,该处理下的土壤含水率、葡萄水分生理指标和产量均处于较高水平。

       

      Abstract: Soil moisture is different under different layout style of drip irrigation pipeline, which will affect crop growth and its yield. In this study, soil moisture and water physiological indexes under different treatments during grape ripeness were measured and analyzed in order to investigate the effect of layout style of pipeline and technical parameters of drip irrigation system on grape’s growth, yield and select the optimal technique parameters of drip irrigation that suitable for TuHa Basin. The results show that the treatment with three surface drip irrigation pipelines,outlet flow of 2.7 L/h and the distance of 30 cm between the emitters has the optimal results. Under the condition of this treatment, soil moisture, grape’s water physiological indexes and yield all reach a higher level.
