An experiment was carried out in Shanghai Haifeng Modern Agriculture Co LTD, to study the effects of different sowing date on plant type and ear characters of direct seeded rice of Huaidao 5, Wuyujing3, Wuyunjing21. The preliminary results were as follows: the best sowing date of direct seeded rice was in early June in Haifeng region. With delayed sowing date, the plant heights, upper internodes, the number of primary branches and secondary branches, the grain number per panicle were decreased, the lower internodes were increased. The delayed sowing date had less effects on ear characters, plant heights and yields of Wuyunjing 21 and Huaidao 5 than that of Wuyujing 3.
