丽水地区茶园绝大部分是建在山坡上,这种立地条件从栽培角度来看,除了排水条件较好以外,存在土壤冲刷严重,表土层浅薄,有机质缺少,茶树容易出现营养不足,土地利用率不高等弊病。因此,如何根据山地茶园特点,采用相应的栽培管理措施,显得尤为重要。树冠结构是茶叶高产优质的基础。山地茶园由于接纳太阳辐射情况与平地不同,因此其树冠结构也应与平地的不同。为了探讨山地茶园产量与树冠结构的关系,为塑造丰产树冠提供依据,笔者对该地区有代表性的6个茶场10片不同产量的茶园进行了实地调查,现将调查结果分析如下。
Lishui tea plantations are mostly built on the hillside, the site conditions from the cultivation point of view, in addition to better drainage conditions, there are serious soil erosion, topsoil shallow, lack of organic matter, tea is prone to undernutrition, land use efficiency Not higher ills. Therefore, how to use the characteristics of mountain tea plantations, the corresponding cultivation and management measures, it is particularly important. Canopy structure is the basis of high yield and quality of tea. Due to the fact that the mountainous tea gardens are different from the ground in accepting solar radiation, their canopy structure should also be different from that of the ground. In order to explore the relationship between the yield of mountain tea garden and the structure of canopy, and to provide the basis for shaping the crown of high yield, I surveyed 10 representative tea farms of 6 different tea farms in the region. The results of the survey are as follows.
