- 摘要:
- 以混合草炭（国产草炭+珍珠岩+蛭石）、水苔、PINDSTRUP基质（丹麦泥炭+珍珠岩）3种生产基质为研究对象，系统研究了3种基质的空隙结构、气水比、容重等物理特性，并进行了鸟巢蕨栽培试验。结果表明：混合草炭、PINDSTRUP基质和水苔的干容重依次显著升高（P<0.05），总孔隙度差异不显著；混合草炭和PINDSTRUP基质的通气孔隙度、持水孔隙度和气水比不存在显著差异，但二者的通气孔隙度和气水比显著低于水苔、持水孔隙度显著高于水苔（P<0.05）。不同栽培基质和灌水处理条件下，供试鸟巢蕨的叶片蒸腾速率和光合速率日变化过程一致，灌水定额和基质类型对鸟巢蕨叶片生理有交互影响。PINDSTRUP基质栽培的鸟巢长势最好、水苔次之、国产草炭混合基质长势较差。
- Abstract:
- The physical characteristics of three kinds of substrate and Neottopteris antique culture experiment were investigated.The experimental substrate included mixed peat substrate，PINDSTRUP substrate and sphagna substrate.The experimental Neottopteris antique was planted in plastic pot with three kinds of substrate.The results showed that dry unit weight had obvious difference and total porosity had no obvious difference between the substrates(P<0.05).The water-holding porosity and gas-porosity had no obvious difference between mixed peat substrate and PINDSTRUP substrate，but the water-holding porosity of sphagna substrate was lower and gas-porosity was higher obviously compared with the other two kinds of substrate(P<0.05).The daily change process of leaf transpiration rate and photosynthetic rate were similar for all treatments.The growth and water physiological indexes were influenced by irrigation quota and substrate，the best growth were gained from the PINDSTRUP substrate，the worst growth were gained from the mixed peat substrate.
