| 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. |
