Abstract

See full text

A method for inhibiting microbial clogging of drip irrigation emitters, belonging to the technical field of water-saving irrigation. The method includes the following steps: (1) Use developmental molecular ecological network analysis to determine the key bacteria causing the clogging of drip irrigation emitters, and then carry out screening of antagonistic bacteria to inhibit the clogging of drip irrigation emitters; (2) Ferment the selected antagonistic bacteria in a medium containing biogas slurry, to generate bacterial antagonist; (3) Apply the bacterial antagonist to drip irrigation system. The method uses the molecular ecological network analysis method to obtain key bacteria that cause the growth of biofilm in drip irrigation emitters, and then combines the principle of microbial antagonism to screen out the antagonistic bacteria that can antagonize the growth of biofilm, so as to inhibit the growth of biofilm in irrigation emitters.
