摘要

测定了霜冻夜风机运行时的风速和叶片温度。在风力机前方5.4 m、10.8m、16.2 m、21.6 m、27.0 m处，将热线风速计和温度计并排放置在灌木树冠上。风速在离风机最近的10.8 m处最大，随着距离的增加变化较小。叶温升在5.4 m ~ 10.8 m处最大，但随距离变化较小。在10.8 ~ 27.0 m区间，叶片温升随风速增大而增大。在5.4 m处风速较小，但叶温升高幅度较大。从这些结果来看，空气搅拌法的防霜效果取决于风击中茶树树冠引起的叶温升高，而取决于另一个因素在接近风力机的范围内。

Relationship of Wind Speed and Canopy Leaf Temperature Rise for Air Stirring Frost Protection in Tea Field

Wind speed and leaf temperature under wind machine running were measured in frost nights. Hot-wire anemometers and thermometers were placed side by side on bush canopies in terms of distance 5.4 m, 10.8m, 16.2 m, 21.6 m, 27.0 m points ahead of the wind machine. Wind speed showed a maximum at 10.8 m point closest to the wind machine, but changed smaller as distance. Leaf temperature rise showed a maximum at 5.4 m -10.8 m points, but changed smaller as distance. Between 10.8 - 27.0 m points, leaf temperature rise seemed to increase as wind speed was large. Leaf temperature rise was greater amount despite wind speed is small at 5.4 m point. From these results, frost-protective effect of the air stirring method is dependent on the leaf temperature rise caused by the wind hits the tea bush canopy, but on another factor in the range close to the wind machine.

期刊介绍： The Journal of Tea Science was established in August 1964, approved by the Publicity Department, CCCPC. Its title was inscribed by Zhu De, the chairman of CCCPC. It was discontinued during the Cultural Revolution in 1966, and it was reissued in August 1984, approved by the State Scientific and Technological Commission.Academicians Chen Zongmao and Liu Zhonghuaof the Chinese Academy of Engineering served as the directors of the editorial board. The Journal of Tea Science is managed by the China Association for Science and Technology,sponsored by the China Tea Science Society and the Tea Research Institute of the Chinese Academy of Agricultural Sciences, and edited and published by the editorial office of the Journal of Tea Science. It is the only one of Chinese core journals in the field of tea science that is included in the core library of the Chinese Science Citation Database.Its Domestic Unified Serial Number is CN 33-1115/S, its International Standard Serial Number is ISSN 1000-369X and its International publication name code is CODEN-CHKEF4. At present, the Journal of Tea Science is a bimonthly publication, published in the middle of the month, with a book size of 16.
