摘　　要：以水稻品系T-43为供试材料,采用不同种子处理和不同播种深度进行种植。结果表明,浸种后播种有利于出苗,浸种并播种深度≤2 cm产量最高。产量相关性分析表明:总变异的贡献是种子处理>播种深度>种子处理×播种深度。In the current research,the tested rice line T- 43 was planted under mulched drip irrigation conditions with different seed treatments and sowing depths（ 1,2,3,4 cm）. As a result,seed treatments favored seedling emergence,and seed treatments in combination with a sowing depth of 2 cm or less resulted in the highest yield. Yield correlation analysis indicated that the contribution of treatment to the total variation is in the following order： seed treatment sowing depth seed treatment in combination with sowing depth.
