Abstract:

Peach trees are the main economic fruit tree species planted in the mountainous areas of northern Zhejiang. The selection of tree shape has great significance for improving the yield, quality, and economic benefits of peach trees. This experiment aims to provide a basis for selecting tree shapes in mountainous areas by comparing “the traditional main branches of natural open center (open center shape)”and “main trunk shape”. The results showed that the main trunk shape harvested 8 days earlier than the open center shape, and the main trunk shape was put into production quickly, 60.6% higher compared with the open center shape on production in the third year; The main trunk shape was higher than the open center type in soluble solid content, but the open center shape fruit is more bright; The open center type was 1.95 times than the main trunk shape in pruning cost, while the open center shape was 2.48 times than the main trunk shape peach tree in the field management fee. The main trunk shape is mainly suitable for small machinery under mountainous conditions.

Key words: peach tree, tree shape, mountainous areas, production, fruit quality, agricultural cost
