| In order to fertilize and irrigate properly and get high quality and yield of greenhouse grape under delayed cultivation, the effects of three different fertilization levels (upper level fertilization, middle level fertilization and lower level fertilization) and four irrigation thresholds (Wet, mild stress, moderate stress and severe stress) on quality and yield of “Red Globe” grape were investigated. The results indicate that the effect of different irrigation threshold on the grape diameter and grain weight was extremely significant, the effect of interaction on the figure index become significant. Total soluble solid (TSS) first increased and then decreased with the fertilization level, the titratable acid content increased with the fertilization level. It can increase anthocyanin content and enhance the grape resistance while fertilize and irrigate reasonably. The yield of grape increased with the increase of fertilization level, and first increased and then decreased with the water deficit. By comprehensive consideration of increasing yield and grape quality, under the treatment of upper level fertilization (the content of N, P, K were 161.92, 53.97 kg·hm-2 and 44.98 kg·hm-2 respectively) and moderate stress (55%～60%θf), the yield of greenhouse grape under delayed cultivation was highest and the quality was preferable. |
