Abstract

The invention discloses a composite microbial agent coated biological compound fertilizer and a preparation method thereof. The compound fertilizer is prepared from, by weight, 5-15 parts of compoundmicroorganisms, 400-700 parts of animal waste, 1-10 parts of diammonium phosphate, 1-5 parts of urea and 1-10 parts of potassium phosphate; and the compound microorganisms comprise Candida tropicalis,Bacillus subtilis and Verticillium chlamydosporium. The composite microbial agent coated biological compound fertilizer comprises the Candida tropicalis, Bacillus subtilis and Verticillium chlamydosporium, the Candida tropicalis and Bacillus subtilis can significantly enhance the inhibition effect of Verticillium chlamydosporium on root-knot nematodes. When the composite microbial agent coated biological compound fertilizer is applied to tomato planting as a base fertilizer, the incidence of root-knot nematodes can be significantly inhibited, and high tomato fruit yield can be maintained.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a biological compound fertilizer coated with a compound microbial bacterial agent and a preparation method thereof. Background technique [0002] Root-knot nematodes are widely distributed in the tropics and subtropics, and are obligate parasites of more than 30 common vegetables. Root-knot nematodes affect the growth of vegetables and reduce the yield of vegetables. [0003] The current prevention and control of root-knot nematodes is mainly through physical exposure and the use of chemical pesticides such as metamure, calcium cyanamide, and thiazolyl phosphine. The exposure method is inconvenient and inefficient, and chemical reagents are likely to cause soil pollution and pesticide accumulation in vegetables. Verticillium chlamydia is a widely used microbial agent to inhibit root-knot nematodes. Contents of the invention [0004] The object of the present invention is to provid...
