Influence of two drainage status on fruiting performance of facility grape
To compare the effects of different drainage status on the yield of Southern facilities vineyard, the fruiting performance for Red Globe grape in northwestern Hunan in winter was analyzed under the mode of long shoot pruning. Ridge block from 2 drainage status of design in the observation of 40 sample trees, there are fruiting trees ratio accounted for 77.5% and 37.5%. According to nested trial data structure with ridge block and age factors, variance analysis of all 80 grape trees of fruiting branch rate showed that the two kinds of drainage design were significant difference;a total of 215 mother branches from 31 grape sample trees in total drainage design ridge block was observed, the fruiting mother branch rate was 66.05%. With the same statistical methods, the fruiting mother branch rate was 14.43%. The results show that the drainage status have significant influence on grape fruiting performance, poor drainage make the fruiting trees ratio and fruiting branch rate reduced greatly.
