| 摘 要： | 针对水稻传统耕作导致土壤结构破坏和土壤板结等问题,开展垄作双深耕作模式及不同株行距配置对水稻产量影响的研究。选用水稻品种齐粳10号,采用二因素随机区组试验设计,设置垄作双深和常规平作2种耕作模式、4个株行配置,共8个处理。结果表明：与常规平作相比,垄作双深处理的穗重和一次枝梗数分别显著增加7.88%和7.00%,灌浆期净光合速率、蒸腾速率、胞间CO2浓度和气孔导度分别显著增加9.33%、14.81%、11.46%和27.09%。株行配置方面,株距15cm处理的穴穗重均极显著高于株距12cm处理,穗长随着株行距的减小而减小,株行距为12cm×(17~33)cm处理的穗数最大,平均显著高于其他株行配置12.87%。垄作双深与株行距为12cm×(17~33)cm互作处理产量最高（10 239.12kg/hm2）,显著高于其他处理。

| Abstract: | Based on the problems of soil structure destruction and soil hardening caused by traditional cultivation in rice, the effects of ridge tillage of double depth and different planting spaces on rice yield were studied. The rice variety, Qijing 10, was selected for the experiment, and the two-factor random block design was adopted. The experiment adopted two tillage methods: bilateral deep fertilization on ridge and conventional flat planting, four rows were set for both, and eight treatments in total. The results showed that the panicle weight and the primary branch number under ridge tillage of double depth significantly increased by 7.88% and 7.00% respectively. The net photosynthetic rate, transpiration rate, intercellular CO2 concentration and stomatal conductance increased by 9.33%, 14.81%, 11.46% and 27.09% at the grain-filling stage, respectively. In terms of plant row configuration, the panicle weight per hole treated with plant spacing of 15cm was significantly higher than that of 12cm, the panicle length decreased with the decreasing of the spacing in the rows, the number of panicles will be maximum when the spacing in the rows are 12cm×(17-33)cm, on average 12.87% higher than that of other collocations. The combination of the ridge tillage of double depth and plant spacing of 12cm×(17-33)cm has the highest yield of 10 239.12kg/ha, which was significantly higher than that of other treatments. |
