浙北山地桃树不同树形对产量、品质和成本的影响

Effects of different tree shape of peach tree on fruit yield,quality and agricultural production cost in the mountainous areas of northern

桃树是浙北山地地区主栽的经济性果树树种,而树形的选择对于桃树产量、品质以及经济效益的提升有着重要意义。本试验通过选择传统的三主枝自然开心形(开心形)和主干形的两种树形进行比较试验,以期为山地地区选择树形提供依据。结果表明,采摘时期主干形桃树早于开心形8 d,产量上主干形桃树投产快,第三年产量即高出开心形桃树60.6%;可溶性固形物含量方面,主干形桃树高于开心形,但是开心形果实较为鲜艳;从成本上,修剪成本开心形桃树是主干形的1.95倍,而田间管理费用开心形桃树是主干形桃树的2.48倍,山地条件下主干形行距宽适合小型机械使用。

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.
