摘要
【目的】苔藓植物用途广泛,如保持水土、监测空气污染或运用于园艺景观制作等,但其生长条件苛刻。在近自然条件下,筛选出一种能让苔藓植物良好生长的栽培基质。【方法】采用单因素方法,运用断茎法种植苔藓植物,并通过测定分析苔藓植物的株高、增重量、覆盖率及叶绿素含量等生物学和生理指标的变化,研究10种栽培基质对3种苔藓植物的生长影响情况。【结果】真藓在赤玉土中种植其生理指标达到最大(株高1.44cm、增重量3.8281g、覆盖率95.86%、叶绿素含量207.13mg/kg),与种植于硅藻土中的真藓(株高0.41cm、增重量1.0800g、覆盖率29.89%、叶绿素含量45.55mg/kg)相比具有显著差异;鼠尾藓在赤玉土中种植其生理指标达到最大(株高3.76cm、增重量4.7746g、覆盖率92.50%、叶绿素含量89.21mg/kg),与种植于绿沸石中的鼠尾藓(株高0.98cm、增重量1.1344g、覆盖率40.26%、叶绿素含量36.70mg/kg)相比具有显著差异;尖叶匍灯藓在赤玉土中种植其生理指标达到最大(株高5.09cm、增重量3.9970g、覆盖率90.71%、叶绿素含量126.39mg/kg),与种植于硅藻土中的尖叶匍灯藓(株高1.75cm、增重量1.1818g、覆盖率41.62%、叶绿素含量37.81mg/kg)相比具有显著差异。【结论】赤玉土可作为大多数苔藓植物较优的栽培基质;栽培基质能对苔藓植物的生长产生一定的影响。
【Objective】Bryophytes are widely used,such as maintaining soil and water,monitoring air pollution,or making horticultural landscape,but their growth lies in harsh conditions.In this study,a substrate capable of allowing bryophytes to grow well was selected from the cultivation substrates under near-natural conditions.【Method】Singlefactor experimental method was used to grow bryophytes by broken stem method,and the effects of 10 kinds of cultivation substrates on the growth of three kinds of mosses were studied by measuring the changes of biological and physiological indexes including plant height,weight gain,coverage rate and chlorophyll content of bryophytes.【Result】The physiological index of the Bryum argenteum planted in the red jade soil reached the maximum(plant height 1.44 cm,weight gain 3.8281 g,coverage rate 95.86%and chlorophyll content 207.13 mg/kg),which was higher than that of the B.argenteum planted in diatomite(plant height 0.41 cm,weight gain 1.0800 g,coverage rate 29.89%and chlorophyll content 45.55 mg/kg).The physiological index of the Myuroclada maximowiczii planted in the red jade soil reached the maximum(plant height 3.76 cm,weight gain 4.7746 g,coverage rate 92.50%and chlorophyll content 89.21 mg/kg),which was higher than that of the M.maximowiczii planted in the green zeolite(plant height 0.98 cm,weight gain 1.1344 g,coverage rate 40.26%and chlorophyll content 36.70 mg/kg).The physiological index of the Plagiomnium acutum(Lindb.)T.Kop.planted in the red jade soil reached the maximum(plant height 5.09 cm,weight gain 3.9970 g,coverage rate 90.71%and chlorophyll content 126.39 mg/kg),which was higher than that of the P.acutum(Lindb.)T.Kop.planted in diatomite(plant height 1.75 cm,weight gain 1.1818 g,coverage rate 41.62%and chlorophyll content 37.81 mg/kg).【Conclusion】Red jade soil can be used as a good cultivation substrate for most bryophytes.The cultivatation substrate has a certain influence on the growth of bryophytes.
