| Abstract: |
| 【Objective】To explore the coordinated model of water and fertilizer for grape fruit growth, yield and quality improvement under drip irrigation.【Method】Three irrigation levels(W1:10950 m3/hm2, W2:9150 m3/hm2, 7800m3/hm2) and three fertilization levels(N1:750 kg/hm2, N2:450 kg/hm2, N3:300 kg/hm2), a total of 9treatments were randomly combined with 3 replicates for each treatment. The field experiment of water and fertilizer coordination was carried out to study the effects of water and fertilizer coordination on grape grain growth, yield and quality.【Result】The appearance quality, 100-grain quality, yield and quality of grape were positively promoted by the appropriate coordination of water and fertilizer. Under the coordination of water and fertilizer, the appearance quality, 100-grain weight, yield, soluble solids and hardness of grape treated by W2N2 were superior to those of other treatments. The solid-acid ratio of grape treated by W2N3 was the best, but the difference was not significant with that of W2N2. Vitamin C, W1N1 treatment was the best, and the difference was significant with that of other treatments.【Conclusion】The effects of water and fertilizer on grape indexes were comprehensively compared. W2N2 treatment was the optimal water and fertilizer treatment, that is, irrigation amount of 9150 m3/hm2 and fertilizer amount of 450kg/hm2 were the optimal combination of water and fertilizer. Through the establishment of binary quadratic regression model of water and fertilizer yield, it was determined that the amount of water and fertilizer under high yield was 9723 m3/hm2 and 557 kg/hm2, and the target yield was 38636.53 kg/hm2. |
