Effects of different pruning quantity on growth and fruiting in peach
Pruning is one of the most critical management practices for producing high yield of high quality peaches in orchards.In this study,two peach varieties,'Ruipan 10'and'Yuhua 2',were used as materials,and three levels of no pruning(0 pruning),light pruning(nearly 50％pruning)and normal pruning(nearly 70％pruning)were carried out during the dormancy period,so as to explore the effect of winter pruning on vegetative growth and fruiting.The results showed that the proportion of short twigs in the two treatments of no pruning and light pruning was 2.00 times and 1.90 times than the treatment of normal pruning at the end of June in'Ruipan 10',while the proportion of short twigs in the two treatments of delayed pruning and light pruning was 1.19 times and 1.17 times than the treatment of the normal pruning at the end of June in'Yuhua 2',respectively.The yield of the treatment of light pruning was higher than that of normal pruning,and significantly higher than the treatment of no pruning in'Ruipan 10'and'Yuhua 2'treatment.However,the contents of soluble solids and titratable acid were not significantly different among the three treatments.This study provides a significant reference for pruning management in peach production.
