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.

The present invention is directed to a process for the preparation of liquid or sludge slow-release compositions suitable for agricultural use, comprising one or more active ingredients selected from the group consisting of fertilizers, pesticides, lipophilic and/or hydrophilic compounds, and mixtures of non-pathogenic bacteria together with lipophilic and/or hydrophilic compounds, wherein these actives become encapsulated in an alginate matrix. The direction also encompasses compositions prepared by this process and methods for using said compositions for the delivery and slow release of agrochemicals and other actives in close proximity to the roots of plants.
