摘要 | 为探索快速培育黄土高原苔藓结皮的关键影响因子,利用正交试验设计方法,研究了表层土壤含水量、
光照强度和接种量3种因素对黄土高原苔藓结皮生长发育的影响,初步探讨了在黄土高原地区快速培育苔
藓结皮的可行性。结果表明:(1)表层土壤含水量、光照强度及接种量均对黄土高原苔藓结皮(土生对齿藓为
优势种)盖度、株密度和生物量的变化有极显著影响(P<0.01)。(2)对苔藓结皮盖度和株密度而言,3种因素
的影响顺序依次为表层土壤含水量>光照强度>接种量;对生物量而言,其影响顺序依次为表层土壤含水量
>接种量>光照强度。(3)快速培育黄土高原苔藓结皮的最佳因子组合为表层土壤含水量25%~30%+
光照强度1 000lx+接种量700g/m2,在人工气候室条件下培育40d,苔藓结皮盖度可以迅速达到95%。 |
其他摘要 | In order to explore the key influential factors of rapid cultivation of moss crusts on the Loess
Plateau,the orthogonal experimental design method was used in the test to analyze the influences of surface
soil moisture,light intensity and inoculation amount on the growth and development of moss dominated
crusts,and to explore the feasibility of rapid cultivation of moss dominated crusts on the Loess Plateau.The
results showed that(1)surface soil moisture,light intensity and inoculation amount had extremely significant effect
on the change of coverage,density and biomass of moss crusts which was dominated by Didymodon vinealis
(Brid.)Zand(P<0.01).(2)As for the coverage and density of moss dominated crusts,the influence order
of the three factors was surface soil moisture,light intensity,and inoculation amount;as for biomass,the
influence order of three factors was surface soil moisture,inoculation amount,and light intensity.(3)The
best combination of factors for rapid cultivation of moss dominated crusts on the Loess Plateau was surface
soil moisture(25%to 30%),light intensity(1 000lx),and inoculation amount(700g/m2).Under environmental
chamber condition,the coverage of moss dominated crusts could rapidly reach 95%in 40days. |
