Abstract
The arrangement of sowing stage is a very important step for agricultural production. Comparative experiments on different sowing stages of two Brazil upland rice were applied, the results showed: The best sowing stage of Brazil upland rice was May 10, and the yield was maximal. LAI and chlorophyll of functional leaves in full head stage was maximal among different sowing stages, then them declined along with the aging of vegetation. Root vigorous declined along with the delay of sowing stage after full heading stage, and the difference of root vigorous in full head stage was not significant among different sowing stages, but it was significant in the subsequent stages. The lower of full spikelets per panicle and seed setting rate were the limitative factors on yield.关键词
