菇娘基质育苗效果研究

目的]为了探索适合菇娘育苗的基质配方,为菇娘培育壮苗提供理论依据。方法]以1∶1体积的椰糠和河沙作为对照,研究不同育苗基质对菇娘生长、干物质积累、壮苗指数及育苗时间的影响。结果]源农泥炭及1∶1体积的源农泥炭和椰糠混合的基质物理性能优良,容重小,总孔隙度及通气空隙度较大,透气保水性能较佳。1∶1体积的源农泥炭和椰糠混合处理的菇娘株高、真叶数、根长、真叶宽、真叶长等生长指标,叶干鲜重、根干鲜重等物质积累指标及壮苗指数均最高,显著大于对照处理,成苗时间最短。结论]因此,1∶1体积的源农泥炭和椰糠混合是菇娘育苗的理想基质配方。

Effect of Seedling Substrate for Physalis pubescens L.

Objective]The purpose of this study was to find the suitable seedling substrate for the Physalis pubescens L.to offer reference for culturing strong seedling.Method]Used mixed substrate of coconut coir and river sand with a volume ratio of 11 as a comparison, studied effects of different substrate on growth, dry matter accumulation, seedling strength index and seedling time of Physalis pubescens L.. Result] Yuannong seedling substrate and the mixed substrate of Yuannong and the coconut coir with a volume ratio of 1:1 had a better physical proper-ties.For their smaller bulk density, and higher total porosity which showed better permeability and water-retaining property than others.The growth index ( plant height, number of leaves, root length, leaf length and width) , dry matter accumulation( leaf fresh weight and dry weight, root fresh weight and dry weight) and seedling strength index of the mixed substrate of Yuannong and the coconut coir with a volume ratio of 1:1were best, and it was significantly greater than the comparison treatment.Its seedling time was shortest.Conclusion]The mixed substrate of Yuannong and the coconut coir with a volume ratio of 1:1 is the ideal substrate for seedling of Physalis pubescens L..
