2021-2022年太行山区核桃主产区树体性状分析的原始数据

2021年至2022年2年内，每年的7-9月，每月去1次，在河北涉县、武安、隆尧、临城、赞皇、元氏、井陉、唐县、曲阳、顺平等地对太行山核桃主产区辽宁1号核桃品种的树体特性进行观测比较后得到的数据。得到的指标包括：树龄、株高、干周、枝展、株产等。

This dataset is derived from field observations and comparative analyses conducted over two consecutive years (2021 to 2022). One survey was carried out per month during July to September each year in major walnut-producing areas of the Taihang Mountains across multiple counties in Hebei Province, including She County, Wu'an, Longyao, Lincheng, Zanhuang, Yuanshi, Jingxing, Tang County, Quyang, Shunping and other relevant regions. The target cultivar was 'Liaoning No.1' walnut. Measured indicators include tree age, plant height, trunk circumference, branch spread, yield per plant, and other related tree growth traits.
