【目的】在吐鲁番戈壁砾石地和极度干燥气候条件下,研究葡萄根域限制方式和自压软管灌溉对葡萄生长发育的影响,摸清自压软管的灌水量、灌溉周期和栽培管理措施。【方法】设置三个不同灌水量,采用自压软管灌溉与根域限制结合的栽培方式,研究其对无核白新梢粗度、叶面积、果粒大小、含糖量、产量的影响。【结果】采用自压软灌灌溉,灌水量控制1 025 m3/667 m2时,葡萄产量达到1 508.5 kg/667 m2,单粒重2.5 g,灌水量在867 m3时,产量只有1 348 kg/667 m2。【结论】在吐鲁番地区实行软管与根域限制结合的栽培方式,灌水量较常规沟灌减少灌溉量近40%,葡萄单粒重、可溶性固形物含量、单产与沟灌基本相当。
【Objective】 Under the condition of Gobi gravel and extreme dry climate in Turpan, the effects of root restraints and self-pressured hose irrigation on the growth and development of grape were studied, and the irrigation volume, irrigation cycle and cultivation management measures of self-pressured hose . 【Method】 Three different irrigation modes were set up, and the cultivation methods of self-pressured tube irrigation combined with root zone limitation were used to study the effects on the thickness, leaf area, fruit size, sugar content and yield of seedless white shoots . 【Result】 The results showed that the yield of grape reached 1 508.5 kg / 667 m2, single grain weight 2.5 g and irrigation volume 867 m3 with only 1 348 kg / 667 m2. 【Conclusion】 In Turpan region, the combination of hose and root zone restriction was applied. The irrigation volume was reduced by nearly 40% compared with conventional furrow irrigation. The single grain weight and soluble solids content of grapes were almost the same as those of furrow irrigation.
