摘要

In the previous report, the author presented the fact that the percentage of fructiftcation in upland rice plant was higher when transplanted, but the crop yield was usually poor owing to the decreased number of tillers developing. In this paper, he tried to know of some measures for improving the crop by shifting the time of transplanting and proper spacing. The results were as follows : 1) Sown at the same date and suplied with the same amount of fertilizers under the same plant density, the yields obtained from the transplanted plots were always lower compared to those from the direct sowing plots. 2) When sown in nursery 20 days earlier than the standard time of direct sowing and grown up in nursery for 40 days, and then transplanted at the rate of 2 seedlings per hill spaced at 12×9cm, the crdp gave a yield 4∼10% smaller than that of directly sown crop. While the crop, when transplanted at the rate of 2 seedlings per hill spaced at 6×9cm gave about the same amounts of yield as that of the direct sowing method. The labour requirement in the transplanting culture method was found 5∼10% less than that of the direct sowing method. In pradtices of transplanting method, however, many other factors such as fertilizers, the variety of rice and rotation system, including mix.culture of rice with other crops, etc. should be taken into consideration.
