Effects of Cyanobacteria-bacteria Biological Crusts on Soil Moisture and Nutrient Conservation and Maize Seedling Growth
[Objective] The effects of cyanobacteria-bacteria biological crusts on moisture and nutrient conservation and maize seedling growth were studied to provide a theoretical basis for soil treatment and improvement strategies. [Methods] Two species of bacteria (Sphingomonas sp. D3-1 and Massilia armeniaca sp. ZMN-3) and two species of cyanobacteria (Cladophora aegagrophila D3-a and Nostoc sphaeroides D3-25) isolated from the Wengniute Desert of Inner Mongolia Region
were used to prepare biological crusts. The relationships between the cyanobacteria-bacteria biological crusts and soil moisture and nutrient conservation
soil microbial quantity and soil enzyme activity were explored
and the effect of biological crusts on maize seedling growth was studied. [Results] Compared with the control
the soil surface cyanobacteria-bacteria crust significantly declined the rate of soil moisture loss
and reduced the average leaching efficiency of nitrogen
phosphorus and potassium by 76.9%
64.4% and 47.8%
respectively
while increased the number of bacteria
fungi and actinomycetes in soil by 8.3 times
1.8 times and 3.1 times
respectively
and decreased the number of bacillus by 12.4%. Besides
in the corn plants
the cyanobacteria-bacteria crust increased the aboveground fresh/dry weight
root fresh/dry weight
and above/lower length of corn seedlings by 45%/57.8%
54.6%/32.8% and 19.7%/14.5%
respectively
and the chlorophyll content increased by 5.7%. [Conclusion] The mixed soil biological crust formed by cyanobacteria and extracellular polysaccharide producing bacteria significantly improved the soil microbial and fertilizer conservation effect
which could provide a reference for developing a new way of soil management.
