| 摘要: |
| 【目的】定量综合分析调控灌溉下北方葡萄产量及灌溉水分利用效率的影响因素,综合评价中国北方葡萄园最佳灌溉定额的区域合理性。【方法】以充分灌溉为对照,基于45篇公开发表的学术论文中所收集的316对葡萄产量与灌溉水分利用效率观测数据数据,采用Meta方法对调控灌溉条件下的田间试验结果进行综合归纳,并通过回归分析与亚组分析探讨了对产量和水分利用效率的影响因素；使用反距离权重对试验站点的最佳灌溉定额值进行插值得到最佳灌溉定额的区域图。【结果】与充分灌溉相比,调控灌溉使北方葡萄减产710.37kg/hm2,灌溉水分利用效率提高1.19kg/m3。不同品种的灌溉水分利用效率对调控灌溉响应不同,鲜食葡萄“户太8号”呈显著负效应,“阳光玫瑰”正效应最强。鲜食葡萄比酿酒葡萄增效率高61%,在壤土和砂质土类型的园区,进行全生育期或者着色成熟期轻度调控灌溉更能稳产增效。考虑品质等因素得到的鲜食葡萄最佳灌溉定额与理论灌溉量的数值区间、空间分布基本吻合,酿酒葡萄空间分布基本吻合,数值区间整体低于理论灌溉量。【结论】调控灌溉下中国北方葡萄减产但增效,鲜食葡萄最佳灌溉定额与理论灌溉量基本匹配。 |

| Abstract: |
| 【Objective】The aim was to quantitatively and comprehensively analyze the influencing factors of grape yield and irrigation water use efficiency under regulated deficit irrigation in northern China, and comprehensively evaluate whether the best irrigation quota was matched with the theoretical irrigation amount in vineyards in northern China.【Method】Taking full irrigation as control, based on 316 pairs of grape yield and irrigation water use efficiency observation data collected in 45 published academic papers, the field experiment results under regulated deficit irrigation were comprehensively summarized by Meta method, and the influencing factors on yield and water use efficiency were discussed by regression analysis and subgroup analysis. The inverse distance weight was used to interpolate the optimal irrigation quota values of 41 test sites to obtain the regional map of the optimal irrigation quota.【Result】Compared with full irrigation, regulated deficit irrigation reduced the yield of northern grape by 710.37 kg / hm2, and increased the irrigation water use efficiency by 1.19 kg / m3. The response of irrigation water use efficiency of different varieties to regulated deficit irrigation was different. " Hutai 8 " showed an indigenous negative effect, and " Sunshine Rose " had the strongest positive effect. Overall, fresh grapes increased efficiency by 61 % than wine grapes, in loam and sandy soil type of park, the whole growth period or coloring maturity of mild deficit irrigation is more stable yield and efficiency. The optimal irrigation quota of fresh grapes obtained by considering quality and other factors is basically consistent with the numerical range and spatial distribution of theoretical irrigation amount, and the spatial distribution of wine grapes is basically consistent. The numerical range is generally lower than the theoretical irrigation amount.【Conclusion】Under regulated deficit irrigation, the yield of grapes in northern China decreased but increased, and the optimum irrigation quota of fresh grapes was basically matched with the theoretical irrigation amount. |
