Effects of Different Cultivation Substrates on the Growth of Three Bryophytes

【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.
