粉煤灰替代草炭作基质的烤烟漂浮育苗效果

Effect of coal ash in float seedling production of flue-cured tobacco compared with grass carbon

以粉煤灰为主要原料完全替代烟草漂浮育苗基质配方中的草炭,再添加不同比例珍珠岩作为主处理,以草炭为基质主要原料作为对照,进行常规漂浮育苗和大棚育苗试验。结果表明:用粉煤灰完全替代草炭作为育苗基质的处理,其出苗率、成苗率、壮苗率,都与以草炭为基质主要材料的对照没有显著差异,粉煤灰可以作为烤烟漂浮育苗基质草炭的替代材料。5%珍珠岩和95%粉煤灰是粉煤灰基质配方组合的最佳使用比例。

Coal ash supplemented with perlite was used to replace grass carbon as media in tobacco seedling production with floating system. Results showed that there was no significant difference from control in emergence rate,stocking percent and rate of seedling strength. Coal ash can be used to replace grass carbon as media in tobacco seedling production with floating system. Result also indicated the best ratio of 5% perlite and 95% coal ash.
