The application provides a water-retaining
soil conditioner containing high-efficiency degrading
bacteria and a preparation method and application thereof, and belongs to the technical field of soil improvement.The water-retaining
soil conditioner comprises a carboxymethylated modified
humic acid-
chitosan compound, modified attapulgite
powder, a composite microbial inoculum, konjac glucosan,
polyacrylic acid,
bentonite,
polyglutamic acid,
sodium alginate,
mushroom residue, seaweed residue and
straw compost; the composite microbial inoculum is obtained by combination of
Candida tropicalis, Bacillus smithii and Bacillus pasteurii.The application realizes precise
adaptation of the carrier and the high-efficiency degrading bacterial group by optimizing the design of the composite water-retaining carrier and introducing specific bacterial combinations, strengthens the synergistic effect of
water retention,
bacteria fixation, slow release and soil improvement, realizes
water retention, degradation and fertilization synergistic effect, and has important practical significance and application value for improving
soil quality, guaranteeing
crop production and promoting the development of
ecological agriculture.
