배추, 무우, 토마토, 오이에 대(對)하여 표준시비(標準施肥) 및 질소비료(窒素肥料)와 가리비료(加里肥料)를 50%증시(增施)하고, 토양수분(土壤水分)을 10%, 21%, 33%로 하여 아질산(亞窒酸)가스 0.05, 0.10,
This study was carried out to find out the effects of nitrogen dioxide gas on vegetable crops. Chinese cabbage, radish, tomato and cucumber were used for this experiment, and these crops were fumigated with various concentration of nitrogen dixoide gas for 2 hours under the different condition of light and soil water at the vegetable growth stage. The results obtained were as follows. The crops damages measured by percentage of leaf destruction were more severe at the night time fumigation than at the day time, under the full sun condition than under the shading, and at the higher soil water contents than at the low soil water contents. The cucumber plant showed the highest resistance to nitrogen dioxide gas and tomato plant showed the least resistance. As the nitrogen dioxide concentration increased from
