摘要

[目的

]

研究芽孢杆菌与植物生长调节剂对苔藓结皮生长发育的影响，为提高苔藓结皮种源扩繁效率提供科学依据。[方法

]

选择芽孢杆菌（胶质芽孢杆菌/巨大芽孢杆菌）与生长调节剂（噻苯隆）2种因素，设计双因素完全试验，观测温室条件下苔藓结皮的覆盖度、株高度和株密度。[结果

]

①只添加胶质芽孢杆菌处理的苔藓生长状况最优，相比对照组（未添加芽孢杆菌及生长调节剂）分别提高了苔藓覆盖度（+18.9%）、株高度（+0.85 mm）和株密度（+15.44株/cm

）；②添加巨大芽孢杆菌能提高苔藓株密度（+5.76株/cm

），但会减小其株高度（-0.78 mm），对盖度则无显著影响；③生长调节剂TDZ减小了苔藓植物覆盖度（-11.78%）、株高度（-3.33 mm），对株密度影响不显著；④芽孢杆菌与生长调节剂存在交互作用，巨大芽孢杆菌+TDZ处理增大了苔藓株密度（+9.79株/cm

），且高于只添加巨大芽孢杆菌处理（+3.67株/cm

），胶质芽孢杆菌+TDZ处理增加苔藓株密度（+4.3株/cm

）但弱化了胶质芽孢杆菌的促进作用（-11.14株/cm

）。[结论

]

功能性微生物与生长调节剂对苔藓结皮生长发育具有显著影响，在今后苔藓结皮种源扩繁实践中应加以考虑和借鉴。

Abstract

[Objective] The effects of Bacillus and a plant growth regulator on the growth and development of moss biocrusts were studied in order to provide a scientific basis for improving the provenance propagation efficiency of moss biocrusts.[Methods] A two-factor complete experiment was designed to observe the coverage

height

and density of moss biocrusts under greenhouse conditions by selecting Bacillus(B. mucilaginosus/B. megaterium) and growth regulator (Thidiazuron

TDZ) as the two variables.[Results] ① The growth status was optimal after the addition of B. mucilaginosus

which increased the coverage (+18.9%)

height (+0.85 mm)

and density (+15.44 strains/cm) compared to the control group (no Bacillus and growth regulator). ② After the addition of B. megaterium

the density of moss biocrusts increased (+5.76 strains/cm2); however

the height decreased (-0.78 mm) and the coverage was not significantly changed. ③ Treatment with TDZ reduced the coverage (-11.78%) and height (-3.33 mm); however

it had no significant effect on the density of moss biocrusts. ④ The growth status of BSC was significantly affected by the interaction of Bacillus and TDZ. The combination treatment of B. megaterium and TDZ increased the density of moss biocrusts (+9.79 strains/cm2) and was higher than that of the treatment where only B. megaterium was added (+3.67 strains/cm2). Additionally

the combined treatment of B. mucilaginosus and TDZ increased the density of moss biocrusts (+4.3 strains/cm2); however

it weakened the positive effect of B. mucilaginosus (-11.14 strains/cm2).[Conclusion] The effects of functional microorganisms and a growth regulator on the growth and development of moss biocrusts are very significant

which should be considered during the practice of provenance propagation of moss biocrusts.
