| Abstract:【Objective】In order to explore the effect of different drip irrigation and irrigation quota ongrowth, yield and quality of wine grape under the gravel soil condition in the eastern foot of Helan Mountain.【Method】The effects of different drip irrigation and irrigation quota on growth, photosynthesis, yield and quality of wine grape were studied by two factors and three levels of randomized block experiment.The factors of drip irrigation include three levels: no film drip irrigation (A1), drip irrigation above film (A2) and drip irrigation under film (A3). The factors of irrigation quota include three levels: high water (W1), middle water (W2) and low water (W3) during the growth period. There are 9 treatments in the whole experiment.【Result】Drip irrigation with film and increase irrigation quota appropriately can effectively promote the growth and development of wine grape. The average level of new shoot length and stem diameter was 4.49% and 6.77% higher than that of drip irrigation without film. With the increase of irrigation quota, the 100 grain weight and yield of wine grape gradually increase. The average yield of drip irrigation under film and drip irrigation above film was 48.26% and 20.26% higher than that of drip irrigation without film The sugar acid ratio of drip irrigation under mulch was in the range of 35.23~43.32, which was more reasonable than other drip irrigation methods.【Conclusion】The results show that under the condition of 126.3mm rainfall in the gravel soil planting area at the eastern foot of Helan Mountain, the growth, yield and quality of wine grape are better when the combination of drip irrigation under film and irrigation quota is 2295 m-3·hm-2. If the irrigation quota is not changed(irrigation quota is 2295 m-3·hm-2), the drip irrigation system under mulch is more suitable if the irrigation is adjusted 5~7 times, at the eastern foot of Helan Mountain,. |
