为合理施肥灌水，实现设施延后栽培葡萄的优质高产，就3个施肥水平（高肥、中肥、低肥）和4个灌水水平（丰水、轻度胁迫、中度胁迫、重度胁迫）对“红地球”葡萄的产量和品质的影响进行了研究。结果表明：灌水量对葡萄纵横径和单粒重的影响达到极显著水平，水肥互作效应对果型指数呈显著水平，可溶性固形物随施肥量的增加先增加后减小，可滴定酸含量随施肥量的增加而增加，适量的施肥和适度的缺水可增加花色苷含量，提高糖酸比，葡萄产量随施肥量的增加而增加，随水分的亏缺先增大后减小。综合考虑产量和品质，中肥（N 、P 、K 分别为161．92、53．97 kg?hm －2和44．98 kg?hm －2 ）和中度胁迫（55％～60％田间持水量）处理组合产量最高，品质较佳。

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 in-creased 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 treat-ment of upper level fertilization (the content of N ,P ,K were 161 .92 ,53 .97 kg?hm - 2 and 44 .98 kg?hm - 2 respective-ly) and moderate stress (55% ~ 60% θf ) ,the yield of greenhouse grape under delayed cultivation was highest and the quality was preferable .
