| Abstract: |
| In order to determine the most ideal processing mode for grape with facility-delayed cultivation, the influences by different ways of irrigation amount and mulching methods were investigated on grape growth characteristics, changes of fruit diameter size during enlargement period, and quality, yield and water use efficiency during mature period. The results showed that for the same kind of mulching treatment, plant growth characteristics including new tips, the size of fruit weight and soluble solids content, Vc content were not significantly different between treatments by two different water levels (P＞0.05). Under different ways of mulching, soluble solids and Vc contents of grapes by moderately regulated deficit irrigation were higher than those by standard irrigation. Under the same water gradient, compared with no mulching treatment, new-tip growth characteristics, size and weight of fruit, content of soluble solid and Vc by other treatments were increased, especially by the straw stalks plastic mulching method. Different treatments could improve grape yield and water use efficiency. Straw stalks plastic mulching treatment under moderate water deficit treatment could achieve the largest yield and water use efficiency, reaching 36 381.1 kg·hm-2 and 6.29 kg·m-3, respectively. In conclusion, straw stalks plastic mulching treatment under moderate water deficit can result in the largest weight of fruits, yield and water use efficiency. This conclusion can be popularized and implemented toward future water saving, and high-quality irrigation system for planting grapes. |
