In order to get an effective and economical burning method, especially that of a spacing of oil-burners in a vineyard, we investigated horizontal and vertical distributions of air temperature in the experimental field before and after lighting.
The experiments were carried out at Kikyogahara in Nagano Prefecture on May 19-23, 1953.
In the results of the experiments, we found a good, uniform distribution of the warm zone, with the temperature rise of 1.5° to 2°C in the whole experimental field and of 3°C in the middle, when small tins (the diameter 14cm) were hung at the height of 90cm under the trellis and were spaced in such a manner that there is about one heater in every 4sq meters. (See Fig. 3.)
