中文摘要 | 四種有機介質中以稻桿堆肥的極有效水分含量( 0-10KPa 壓力之間的含水量差值 )最高為 0.08 g/ml。泥炭土、蔗渣堆肥、金針菇堆肥三種介質的水分含量相近。隨著栽培 時間增加,總體密度增加,總孔隙度減少,充氣孔隙度減少, pH 值降低,EC 值增加,CEC 值增加,C/N 比減少。水分含量有增加趨勢,但增加的趨勢不顯著。 |
英文摘要 | 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. Bulk 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. |
