The Analysis on the Meteorological Factors of the Wine Grape Growing Region in Shangri-la Area

摘要

Shangri-La, which located in Yunnan Province of China, has special geographical conditions of low latitude and high altitude, its environmental factors directly affects the growth and quality of grape. In this paper, the meteorological data is collected and monitored by automatic weather observation instruments to study the meteorological factors in particular terrain environment. Meanwhile, this paper does a preliminary analysis of the correlation of key meteorological factors of 6 meteorological stations in different altitude, latitude and longitude along the Jinsha River and Lantsang River. According to the rule of the variation of meteorological elements, the change laws of various meteorological factors of wine grape are analyzed respectively in the period of flowering (early May to early June), discoloring (early July to early September), and picking (in the middle of the middle of September to November). In particular, USB4000 Fiber Optic Spectrometer is used by collecting and analyzing thedistribution of the solar spectrum in Shangri-La area. It is found that, Shangri-La area has less rainfall, bigger total radiation and ultraviolet radiation, significant temperature changes, smaller relative humidity changes, almost identical various spectral distribution regularity in the sun, and increasing sunlight intensity with altitude rising. The results can provide a reference for the development of local wine grape planting.
