摘要

Woodnat项目(H2020)的目标是确定在欧盟2080/92法规和农村发展计划的财政支持下建立的核桃种植园中导致产量低的问题,并改善对较小品种的市场需求。该项目框架内监测到的一些种植园需要疏伐:一个是1994年建立的一个试验林,有5个不同布局和物种的地块,于2018年春季疏伐;第二个是1996年建立的一个由普通核桃、杂交杨和护树组成的多环人工林,2017年春季对核桃进行了间伐。在间伐时,在每个地点随机选择的5棵树的底部采集样本盘,以测定径向、切向和纵向的密度和收缩率。平均密度为0.52g/cm3;平均切向收缩率为12%,而平均径向收缩率为6.7%。来自两个地点的样品之间的行为存在差异,可能是由于不同的植物材料、种植园的年龄和栽培模式。

Common walnut (Juglans regia L.) wood characteristics in two Italian plantations
The Woodnat project (H2020) has the goal of identifying the problems that led to poor yields in walnut plantations established under the financial support of EU 2080/92 Regulation and Rural Development Programme, and of improving the market demand for smaller assortments. Some of the plantations monitored in the framework of the project needed thinning: one,  an experimental stand with 5 plots with different layouts and species established in 1994, was thinned in spring 2018; in a second one, a polycyclic plantation established in 1996 with common walnut, hybrid poplar and nurse trees, the walnut was thinned in spring 2017.  At thinning, sample disks were taken at the base of 5 trees randomly selected at each site for the determination of density and shrinkage in the radial, tangential and longitudinal direction. The average density was 0.52g/cm 3 ; the average tangential shrinkage was 12%, while the average radial shrinkage was 6.7%. There were differences in behaviour between the samples from the two sites, probably due to different vegetal materials, age of the plantations and cultivation models.
