为了研究不同行距插秧机对双季稻产量的影响及配套农艺技术，以11个早晚稻品种为材料，设置8寸和9寸两个机插行距，系统测定不同处理的机插质量和产量。结果表明：8寸插秧机的机插质量高，作业性能稳定；8寸插秧机较9寸插秧机，早稻增产347.30 kg/hm2，增产率达5.49%，晚稻增产579.54 kg/hm2，增产率达9.12%。基于试验支持研究和已有相关研究成果，制定了适应8寸插秧机的配套农艺技术。

The primary objective of this study was to research effect of different row spacing transplanter on rice yield and corresponding agronomic techniques. Field experiments were conducted at Jiangxi province in 2011 and 2012, involving eleven early and late rice cultivars and two row spacing. The mechanical transplanting quality and grain yield of different treatments were measured. The results indicated that the 8 inch rice transplanter has a good mechanized planting quality and stable operation. The 8 inch rice transplanter compare with 9 inch rice transplanter, yield increased by 347.30 kg/hm2 and increase yield rate by 5.49% of early rice. The yield increased by 579.54 kg/hm2 and increase yield rate by 9.12% on 8 inch row spacing more than 9 inch rice transplanter of late rice. Based on experimental support research and related research results, the corresponding agronomic techniques for adapt to 8 inch rice transplanter was established.
