- Abstract
With inoculation of Phanerochaete chrysosporium in shaking flask, this paper studied the degradation of soil p-hydroxybenzoic acid, vanillic acid and ferulic acid under continuous cropping of cucumber, and evaluated the effect of this inoculation in overcoming the continuous cropping obstacle of cucumber. The results showed that after 8 days of inoculation, more than 99% of soil phenolic acids were decomposed by P. chrysosporium. Compared with the control, the contents of soil phenolic acids under 7 years continuous cropping of cucumber declined, with a degradation rate of 54.46%. After inoculating P. chrysosporium, soil fungal population and the plant height, stem width, and fresh and dry mass of cucumber had less change, but the occurrence of cucumber root diseases reduced greatly, with the relative disease index of wilt and root knot nematode declined by 10.2% and 14.6%, respectively. It was suggested that inoculation of P. chrysosporium had definite effect in overcoming the continuous cropping obstacle of cucumber.
