摘要
用根窖法观察了核桃根系和地上部在年周期中的生长关系,以及核桃的根系生长动态与地上部枝、果实等生长的相互关系。结果表明:在间作栽培条件下,核桃根系于10℃地温即开始生长,地温17～19℃为根系生长的适温。在1年当中,根系生长早于地上部,且只有1次生长高峰。
Walnut trees were employed to study the relationship between root and top growth during the whole year. The growth of the roots was observed in the conventional underground observation chamber. The root growth started at 10℃, and the optimum temperature for root growth was 17 - 19℃. During the whole year, one growth peaks were observed.
