| Abstract: | Double cropping late rice seedlings are raised on the dry land bed using the popular combination of Shanyou 64. The optimum sowing quantity is 1.333kg/hm 2. Early transplanting with different sowing quantities shows no significant difference in yied. With delay of the transplanting time and increase in the seedling age, the effective spikes decrease, which causes significant or remarkably significant difference in yield. Different transplanting times cause significant or remarkably significant difference in yield. The critical transplanting date is July 28. |
