摘要:
为研究不同性质的基质对香蒲和芦苇2种优势挺水植物生长的影响，模拟了3种基质（100%粘土、50%淤泥+50%粘土和100%淤泥），研究了香蒲和芦苇的生理生态响应情况。结果显示：香蒲叶片的电子传递速率、最大量子产率和光合能力均随基质中淤泥含量的增加而上升，最大电子传递速率（Pm）和对强光的耐受能力（Pm/α）得到强化，株高也随之增加；在50%淤泥+50%粘土混合基质中生长的芦苇，获得最大株高（138.6 cm）和最大叶长（24.5 cm），而在100%淤泥中株高最低；淤泥比例高的基质中生长的植物对强光的耐受能力（Pm/α）略高于粘土比例高的基质中生长的植物。结论：香蒲更适合生长在肥沃的生态环境中，而芦苇则适合生长在营养水平适中的环境中，即50%淤泥+50%粘土的混合基质可能最适合芦苇生长。
Abstract:
To study the effects of different substrates on the growth of Typha angustifolia and Phragmites communis , after such 3 planting substrates as 100% clay, 50% sludge + 50% clay, and 100% sludge being mimicked, the physiological responses of T. angustifolia and P. communis were investigated. We got the following results as under 100% sludge condition, T. angustifolia had the largest of photosynthesis; and fitting parameters of the light response curve revealed the maximum electron transfer rate ( Pm ); the tolerance to strong light ( Pm/α ) and the plant height were enhanced with the increased proportion of sludge. In addition, the substrate composed of 50% sludge + 50% clay might be the most suitable for the growth of P. communis , with the maximum plant height of 138.6 cm and the maximum leaf length of 24.5 cm while the plant height was the lowest in the 100% sludge substrate. As for these two plant species, the tolerance to strong light ( Pm/α ) was increased in the high proportion of sludge. Therefore we concluded that the response of P. communis and T. angustifolia to organic matter was different from each other, i. e. T. angustifolia tended to grow well in more fertile sediment while P. communis tended to grow better in moderate fertile sediment.
