茶树品种槠叶齐树冠结构动态变化的数学模型探讨

The Mathematical Models Showing the Dynamic Change of the Crown Structure of the Tea Tree

本研究选用湖南省规范化栽培茶园 1～ 18年生的槠叶齐品种为材料 ,以与产量、品质密切相关的 14项树冠结构指标的动态变化规律。测定结果表明 ,树冠结构指标与树龄均可建立相应的数学模型 。

Zhuyeqi' is a fine tea clone developed by the Tea Research Institute of Hunan Agricultural Academy. It is good for black tea production and is under wide extension. In order to provide the growers with a standardized horticultural technique, a test was conducted in search of the changing patterns of the crown structure. Tea gardens from one to eighteen years old were used, and 14 crown-structure related indices relevant to the yield and quality of tealeaves were studied. Results indicated that each index of the crown structure is mathematically correlated with the tree age. Accordingly, 14 models were derived to show the dynamic change of the crown structure.
