摘　　要：以不同类型的水稻品种为材料 ,于 1997～ 1998年在北纬 31°39 的昆山市共青丰产方实施播期试验 ,初步探明了太湖农区生态条件对不同类型水稻品种生育期与产量形成的主要影响 ,从气候生态型角度明确了目前该农区最适宜种植的水稻品种为中熟、早熟晚粳类型 ,最适宜的播种期为 5月 10～ 2 0日 。The study taking various varieties of rice as test materials was conducted in 1997～1998 in Kunshan City.The results are as follows:the growing period and actual yield of rice varieties are influenced by ecologic conditions in Taihu farming region.And the results show that the optimal planting rice type is early middle maturing late japonica variety,the optimal sowing date is between 10～20 May,and the best cultivation tactic is using the appropriate technique to produce mainly large spikes.
