碩士 === 國立中興大學 === 園藝學系 === 85 === Rice straw compost had the highest easily available water (0.08 g/ml), the water content difference goes between 0 and 10 kPa) in four media tested. Water contents of the other three media (peat moss, sugarcane compost, and golden mushroom compost) were closed to each other. Mixing with sand increased EAW in all four media, but EAW decreased if the sand portion would be over 50% V/V. The most efficient EAW increase was made by 25% V/V sand mix. Water contents in the media increased slightly with the time after planting.Buld density, CEC, and EC increased with the time after planting, while TP, AFP, pH, and C/N ratio were decreased on the other way. There were different characteristics for every medium, the correlation between characters were not found for all media, although some correlation were found for individual medium. Three media made from agricultural waste had higher mineral contents than peat moss. High manganese was found in golden mushroom compost, which was the cause of iron deficiency. There was no difference on growth of either Philodendron or Diffenbachia by four media. Four media were reused for growing Begonia after 6 month of Diffenbachia pot growing. Begoniain sugarcane compost had higher plants as well as more dry and fresh weight either for shoot or for root.
