| Abstract: |
| 【Objective】In order to further find out the coordination between dominate wine grape varieties and irrigation system at east-foot of Helan Mountain in Ningxia, enhance the he level of precision irrigation,【Method】 Two-factor strip test was conducted, the dominant grape wine variety ‘Cabernet Sauvignon’ (V1), ‘Matheran’ (V2), ‘Merlot’ (V3), ‘Syrah’ (V4), and ‘Pinot Noir’ (V5) were used as test materials. The conventional irrigation amount was 4500m3.hm-2 as the control group CK(W1), and another four irrigation amount is 4050m3.hm-2(W2), 3600m3.hm-2(W3), 3150m3.hm-2(W4), 2700m3.hm-2(W5) respectively. The growth, yield and quality of different wine grapes were analyzed under the different irrigation amount.【Result】The results showed that: wine grape varieties significantly affected on growth, physiological characteristics. V3 base stem diameter is the largest, flowed by V1, V2, and V4 are centered, and V5 is lowest. V2, V5SPAD value is highest, V3, V1 at middle, V4 is lowest. There are photosynthetic rate (F = 3.82, P <0.01), transpiration rate (F = 2.79, P <0.05) and stomata conductance (F=4.09, P <0.01) significantly difference among wine grape varieties. Irrigation systems significantly affected wine grape growth, physiological characteristics, yield and quality. V1 and V2 base stem diameter under W4 and W5 is superior to other three irrigation treatment, V3, V4, V5 are optimal at W3, W4, W1 treatment respectively. the highest SPAD value of V1, V2 and V5 are under W3 , and with the increase of the amount of irrigation, its variation was firstly increased, then decreased, V3 and V4 increased with increasing amount of irrigation. Irrigation system significantly influenced the transpiration rate (F = 14.48, P <0.01) , by which the single ear weight (F = 19.02, P <0.01) ,total (F = 17.50, P <0.01) ,fruit weight (F = 3.05, P <0.05) ,and fruit particle size (F = 2.76, P <0.05) were very significant effected, and also reducing sugars (F = 24.35, P <0.01), total acid (F = 8.25, P <0.01), tannins (F = 8.88, P <0.01 ) and total phenols (F=8.92, P <0.01) were very significantly affected, soluble solids (F=2.79, P <0.05) is significantly affected. Varieties and irrigation interaction very significantly affect transpiration rate (F = 4.33, P <0.01), by which stomata conductance (F =2.23, P <0.05) was significantly affected, single ear length (F = 4.68, P <0.01) , particle weight (F = 16.28, P <0.01), fruit weight (F = 8.29, P <0.01) and fruit diameter (F=15.77, P <0.01), total yield (F=1.29, P <0.01) were very significant ly impacted, and also soluble solids (F = 34.77, P <0.01), reducing sugars (F =7.68, P <0.01), total acid (F = 3.80, P <0.01), tannins (F =108.61, P <0.01) and total phenols (F=3.71, P <0.01) were very significantly influenced.【Conclusion】It can be concluded that Variety precisely coordinated with the irrigation system, can effectively regulate wine grape growth and quality. |
