摘要
本研究针对丘陵双季稻区,以11个早晚稻品种为材料,采用大田随机区组试验,设置8寸与9寸2个机插行距,研究不同处理条件下的茎蘖动态、干物质量、产量和产量结构。结果表明:8寸行距的干物质量、收获指数和产量均比9寸行距的高;8寸行距的产量比9寸行距平均增产534.86 kg/hm2,平均增产率达8.37%。
Using 11 rice cultivars as materials,the tiller dynamic,dry matter amount,yield and yield structure in 2 row spacings were studied by field randomized blocks design experiment.The results indicated that the dry matter amount,harvest index and yield in 26.6-cm row spacing were all higher than those in 30-cm row spacing.The yield increased by 534.86 kg per hectare and the average yield increase rate reached 8.37%.
