Innovative Experimental Design to Explore the Impact of Micro-bial Fermentation Broth from Kitchen Waste on Plant Growth
This article jointly expands the experiment on"selective cultivation of microorganisms"and the experiment on"exploring the application of plant growth regulators"in the People's Education Press textbook.Cellulose decomposing bacteria,starch decomposing bacteria,and oil decomposing bacteria are separated and purified using a selective culture medium of cellulose,starch,and oil.The sep-arated microorganisms are used to decompose kitchen waste,and the fermentation broth obtained is used as a plant growth regulator.Exploring the effects of different concentrations of kitchen waste fermentation broth on plant growth,the results showed that the isolated microorganisms were easy to cultivate and had strong decomposition ability.The kitchen waste fermentation had promoting effects on seed germination,cuttings rooting,and new leaf experiments.
