| 摘 要： | 在冷浸田设置了5种不同的种植密度试验,对比研究了种植密度对早稻和晚稻的农艺性状和产量的影响,初步掌握了赣中南冷浸田的种植密度,无论早、晚稻,均以每公顷栽插33.75万蔸为最佳密度,可获理想产量。

| Abstract: | A field test for the effects of five different planting densities on the agronomic characters and yield of early rice and late rice in cold waterlogged paddy field in central and southern Jiangxi was conducted. The results indicated that the optimal plant- ing density of both early rice and late rice was 337500 plants/bin2 because the ideal yield could be gained. |
