| Abstract: |
| 【Objective】The objective is to find the best Fertilizer-water of the yield and quality of delayed cultivated grape. 【Method】 A field experiment was conducted to study Four irrigation thresholds and three fertilization levels comprised the fertigation treatments, aimed at the effects of fertilization and irrigation threshold on the water consumption regularity and quality of greenhouse grape under delayed cultivation. 【Result】The results were as follows: the effect of different irrigation threshold on the water consumption, water intensity of greenhouse grape 、Water consumption modulus、Titratable acid of picking period、Anthocyanin was significant; the effect of fertilizer on anthocyanin was insignificant; the effect of different irrigation threshold on measured indicators with the opposite. It can increase the grape yield、promote berry ripening and improve quality while fertilize and irrigate reasonably. 【Conclusion】Under the treatment of 55%~60%θf and the content of N,P,K were 161.92,53.97,44.98kg/hm2 respectively(W3F2)，the yield of greenhouse grape under delayed cultivation can reach 38937.68kg/hm2, the quality was better and water use efficiency can reach 7.86 kg/m3 ,was the suitable water and fertilizer management techniques of experiment grapes. |
