复合茶园光照强度的研究

Study on the Intensity of Illumination in Interplanted Tea Stands

复合茶园能提高茶叶的产量和质量已是不争的事实．然而复合茶园内的光照强度必须符合茶树生长发育需要，过强或过弱都将影响茶叶的产量和品质．因此，研究复合茶园内的光照强度具有重要的理论与实践意义．而计算茶园内各点的光照强度的关键问题是要解决间作树的消光率，通过间作树冠层消光率的计算就可算出茶园各点的光照强度，以作复合茶园设计和调控之依据.

It is well known that interplanting technique can increase the output and improvethe quality of tea． Since the intensity of illumination in interplanted tea stands must be designedand controlled to be suitable to the growth of tea trees， the calculation of the intensity of illumina-tion， and thus the calculation of the dulling rate of the crown canopy of interplanted trees are ofgreat importance theoretically and practically． This paper presents analgorithm by which the dulling rate, and then the intensity of illumi-nation of each point of an interplanted tea plantation can be calculated． Thus， with the aid of thisalgorithm， a quantitative basis of designing and managing interplanted tea plantations can be pro-vided．
