Micro-meteorological characteristics in the vineyard (2)

This paper both includes the difference of micro-meteorological characteristics with the luxuriancy of the trellis of grapes and that when the soybean was planted in the field under the trellis.This investigation was carried out for several days in both summer and autumn, i.e., July 14-15, August 20-21 and November 5-6, 1953, in a vineyard in Tokyo Agricultural Experiment Station.It was samely recognized that there were two layers of thermal importance, i.e., the soil surface and the trellis of grapes as seen in the 1st Report.The vertical distribution of temperature and the relative humidity distribution are shown respectively in Fig. 1, 2 and Tab. 4, 6 with the luxuriancy of the trellis of grapes.The micro-meteorological characteristics in the vineyard was not influenced even when the soyhean was planted under the trellis, shown in Fig. 3, because the trellis has large influency upon the micro-climatology in the vineyard.
