| 2021年在建三江分公司各农场开展大田试验，以‘龙粳31’为材料，比较分析了不同地点叠盘暗室育苗与常规育苗对寒地水稻秧苗素质及产量的影响。研究结果表明，叠盘暗室1.5叶期的株高、叶龄、根数、茎基宽、百株地上鲜质量、百株地下鲜质量、百株地上干质量和百株地下干质量比常规育苗分别提高了46.83%、47.06%、64.78%、14.28%、71.23%、25.60%、67.44%和17.48%；叠盘暗室移栽前的株高、叶龄、根数、茎基宽、百株地上鲜质量、百株地下鲜质量、百株地上干质量和百株地下干质量比常规育苗分别提高了2.84%、9.21%、12.08%、10.53%、12.51%、14.63%、10.83%、8.90%。叠盘暗室育苗方式的出苗率、成苗率和标准苗率极显著高于常规育苗，分别提高了5.21%、5.64%、7.77%，插秧用量极显著低于常规育苗，降低了8.37%。叠盘暗室育苗方式比常规育苗的理论产量、实测产量分别提高了6.32%和5.07%。通过一年多点试验得出，叠盘暗室的秧苗素质极显著优于常规育苗，前哨农场的叠盘育苗增产效果优于其他8个试验农场。在生产实践中应推广叠盘暗室育苗技术。 |

| In 2021, field experiments using‘Longjing 31’ were carried out on the branch farms of Jiansanjiang Company. The effects of stacked pan in darkroom and conventional seedling breeding mode at different locations on the quality and yield of cold region rice seedlings were compared and analyzed. The results showed that, the plant height, leaf age, root number, stem base width, aboveground fresh mass, underground fresh mass, aboveground dry mass and underground dry mass of 100 plants in the 1.5 leaf stage of the stacked pans in darkroom mode were increased by 46.83%, 47.06%, 64.78%, 14.28%, 71.23%, 25.60%, 67.44%, and 17.48% respectively compared with the conventional seedling raising. The plant height, leaf age, root number, stem base width, aboveground fresh mass, underground fresh mass, aboveground dry mass and underground dry mass of 100 plants before transplanting in the stacked pans in darkroom mode were 2.84%, 9.21%, 12.08%, 10.53%, 12.51%, 14.63%, 10.83%, and 8.90% higher than those of conventional seedling raising, respectively. The seedling emergence rate, seedling rate and standard seedling rate of the stacked pans in darkroom mode were significantly higher than those of conventional seedlings, which were increased by 5.21%, 5.64% and 7.77%, respectively. The amount of rice transplanting was significantly lower than that of conventional seedlings by 8.37%. Compared with conventional seedlings, the theoretical yield and the measured yield of the stacked pans in darkroom mode were increased by 6.32% and 5.07%, respectively. The one year’s multi\|point experiment found that the seedling quality of stacked pans in darkroom mode was significantly better than that of conventional seedling raising, and the effect of stacked pans in seedling raising in Qianshao farm was better than that of the other eight experimental frams. In the production practice, stacked pans in darkroom seedlings raising technology should be promoted. |
