Effects of garlic on cucumber growth and soil biology in solar greenhouse

This study was focused on the impacts of garlic amendment on cucumber growth and soil biological properties by potted tests in a greenhouse.The results indicated that adding garlic residue significantly improved cucumber growth.The fresh weight of cucumber was positivly correlated with the added quantity of garlic residues.The numbers of bacteria and actinomycetes were enhanced due to the addition in the whole growth period of cucumber.However,adding 3% garlic residue decreased the number of fungi and fusarium,increased B/F ratio and optimized soil microbial community structure.Moreover,garlic residue increased the activity of polyhenol oxidase,saccharase,urease and catalase of rhizosphere soil at seedling stage.At harvesting stage,the four enzyme activities were significantly high at the adding rate of more than 2.0%,showing improving the environment favorable for the growth of cucumber stage.
