摘　　要：采用直播和移栽两种方式对"上师大3号"水稻进行试种.两种种植条件下的"上师大3号"水稻大多农艺性状基本相同,全生育期分别为149d和150d;两种种植条件收获的水稻产量分别为8863.6kg·hm-2和8407.8kg·hm-2,直播比移栽增加5.4%;经农业部稻米及制品质量监督检验测试中心分析,尽管两种种植条件的"上师大3号"水稻稻米品质指标大多相近,都达到二级食用米标准,但是,移栽方式种植的稻米直链淀粉含量和胶稠度两项指标略好于直播方式种植的稻米.The ＂Shangshida 3＂ rice variety was planted in two patterns, the direct sowing and the transplanting seedlings. Most of agronomic characters of the rice planted by two patterns were basically the same, and their whole growth periods were 149 days and 150 days respectively. The grain yields were 8863.6 kg · hm^-2 and 8407.8 kg · hm^-2, respectively, and the grain yield by the direct sowing was 5.4% over that by the transplanting seedlings. Analyzed by The Quality Supervision, Inspection, ＆ Testing Centre for Rice and Rice Products, Ministry of Agriculture of China, the indexes of amylose content and the gel consistency in the grains harvested from the transplanting seedlings plant were better than those from the direct sowing plant, although most of quality indexes of the grains were similar and accorded with the second grade for the edible rice demand.
