烟草育苗托盘与基质互作效应研究

Research on Interaction Effect of Seedling Tray and Substrate in Tobacco Seedlings

采用育苗基质托盘填装育苗基质的育苗方式和普通托盘填装砂基土的育苗方式对比,研究探索最佳的育苗方式组合,寻求改进育苗质量的新方法。试验结果表明,采用育苗基质托盘填装育苗基质的育苗方式在烟苗的长势,假植的操作环节,托盘的损耗,烟苗根系的发育都具有一定优势。但在保水,基质厚度方面存在不足,建议加高基质育苗托盘的高度,减小托盘底部筛孔的数量和孔径大小,确保托盘的保水性能。

With the comparison of seedling raising style between substrate seedling tray loaded with seedling substrate and ordinary tray loaded with sand, the and new method of improving seedling raising quality seedling raised with suhshale seedling tray loaded with tobacco seedling growlh, operation of temporaryplanting, new style was lacking in water retention and substrate optimal combination of seedling raising style was obtained. The resuhs showed that tile seedling substrate had certain superiorities on tray loss and root development. However, the thickness. So heighten the substrate seedling tray. decrease the number and diameter of tray bottom could strengthen the water retention capacity.
