摘要

The oilpaper-covering nursery-bed of paddy rice is thought to be one of the most important new technics of rice culture in the cold districts of Japan. In this experiment 21 varities of rice were used to know the varietal differences induced by oilpaper-covering in the nursery stage. The plants from oilpaper-covering bed increased the number of stalks in all varieties, and this tend ency was so great in few-stalks varieties, that the varietal difference in stalks-number was disappeared. The heading date was more accelerated in medium and late-ripe varieties, but the yield was not decreased.
