Abstract

Abstract:

In order to study the potential of Chlorella as bio-fertilizer, potted wheat was used as the experimental material, and the effects of Chlorella on wheat growth and soil properties were analyzed under different concentrations. The results showed that irrigation with Chlorella at wheat root could improve the growth of wheat. The plant height was increased by 4.01%-11.99%, and the fresh weight of the aboveground part was increased by 16.01%-29.42%. In addition, the content of chlorophyll a was increased by 4.90%-80.72%, the content of chlorophyll b was increased by 9.38%, and the total content of chlorophyll was increased by 11.99%-48.56%. Meanwhile, soil qualities were improved under Chlorella treatment. The organic matter of soil was increased by 5.26%-6.93%, alkali-hydrolyzed nitrogen was increased by 2.89%-10.14%, available phosphorus was increased by 3.79%-13.11%, available potassium was increased by 6.63%-13.08%, and soil pH was increased by 0.46%-1.62%. In conclusion, the application of Chlorella can not only promote the growth and biomass increase of wheat, but also improve soil quality to a certain extent.

Key words: Chlorella, wheat growth, fertilizer effect, soil properties
