[目的]探究烟苗最佳沙培育苗基质配方。[方法]以贵州德江当地资源稻谷壳和河沙为原料进行基质配方试验。[结果]处理5[草炭(越西)∶河沙∶糠壳∶珍珠岩∶钙镁磷肥=40%∶40%∶0∶20%∶20 g/盘]、处理7[草炭(越西)∶河沙∶糠壳∶珍珠岩∶钙镁磷肥=40%∶15%∶20%∶25%∶20 g/盘]在出苗率及苗期长势上表现优越,烟苗素质达壮苗要求,但处理5在封盘前盘面菁苔较重,需作进一步的微调观察试验;处理7原料成本较2010年德江基质下降22.10元/hm2。[结论]处理7可作为2011年贵州德江烟苗基质生产配方。 [Objective] The research aimed to explore the best sand culture seedling matrix formula for tobacco seedlings. [Method] With the local resources of Guizhou Dejiang rice hulls and river sand as raw material matrix test. [Result] Treatment 5 [peat (Vietnam): river sand: chaff: perlite: calcium magnesium phosphate 40%: 40%: 0:20%: 20 g / : River sand: chaff: perlite: calcium magnesium phosphate = 40%: 15%: 20%: 25%: 20 g / pan] in the emergence of seedlings and superior performance on the seedlings, However, the treatment 5 before the closure of the plate surface heavier, need further fine-tuning observation test; processing 7 raw material costs compared to 2010 Dejiang matrix decreased 22.10 yuan / hm2. [Conclusion] Treatment 7 could be used as the matrix production recipe of tobacco seedling in Guizhou Dejiang in 2011.
