Abstract: The research on delayed cultivating mode was done with ‘Merlot’ and ’Zinfandel’ that had been cultivated for 3 years in Xi’chang experimental vineyard in 2000.With the first growing bunch removed, shoots were pruned to 3~4 buds at 20d, 40d, 60d and 80d after the first blossoming respectively in order to force the hibernacula to sprout, and then the second fruiting were produced by hibernacula accessory shoots. The results indicated that under the delayed cultivating method; the maturity of two varieties could be postponed to 10~20 in Nov. In the treatments, the maximum data of soluble solids and total sugar appeared in the treatment 60d after blossoming. Fruit soluble solids of ‘Merlot’ and ‘Zinfandel’ reached 21.2 oBe and 20.5 oBe(CK were 17.6 oBe and 17.4 oBe)and the total sugar content enhanced 36g/L and 35g/L than that of the control respectively, but the total acid was more than CK. The juice yield decreased with treating time postponed. The maximum yield appeared in the treatment after blossoming 60d, which reached 50.7% and 45.7% of CK. The theoretic yields were about 8019kg/hm2 and 4665/hm2 respectively. The infection of fungi disease was lower than the control except the treatment of 20d. It could be concluded that under the delayed cultivating method, the quality of grape would be enhanced greatly and the maturity of the berry regulated effectively, but it made the yield decrease and prolonged the production period.
