以吐鲁番地区常见的3种葡萄栽培方式为研究对象,采用HOBO were气象站、EI USB 2型温湿度记录仪以及LAI-2200冠层分析仪,测定3种架式叶幕不同部位光合有效辐射(PAR)、温湿度日变化及叶面积指数(LAI),分析各部位微气候差异,以提高吐鲁番地区特殊自然条件下不同栽培架式葡萄的产量及品质,并且为选择适宜的栽培方式提供理论依据。结果表明:不同架式架面内部平均相对PAR和相对温度为小棚架Ⅰ>水平棚架>小棚架Ⅱ,相对湿度反之;同种架式之间PAR最高值出现在架梢处,架中LAI最高;架根处相对湿度最高;架梢到架根相对PAR、LAI及温度呈递减趋势;3种架式中小棚架Ⅰ架面内部结果部位微环境因子的差异相对较小,微气候环境比较稳定。
Taking the three kinds of viticulture methods commonly used in Turpan as research object, the photosynthetically active radiation of different parts of three kinds of frame-type leaves were measured using HOBO were weather station, EI USB 2 temperature and humidity recorder and LAI-2200 canopy analyzer PAR), diurnal variation of temperature and humidity and leaf area index (LAI). The differences of microclimate in different parts were analyzed in order to improve the yield and quality of different cultivated grapevines under special natural conditions in Turpan region, and to provide a theoretical basis for selecting appropriate cultivation methods . The results showed that: the average relative PAR and relative temperature in different shelving planes were small shelving Ⅰ> horizontal shelving> small shelving Ⅱ, on the contrary, the highest PAR value appeared in shelving between shelves, LAI and temperature showed a decreasing trend. The differences of microenvironmental factors in the internal results of the first shelf of three kinds of shelves were relatively small, and the micro-climate Environment is more stable.
