Effects of Nutritious Substance and Bacteriostatic Agent on the Shelf-life of Biofertilizer

Add 4% molasses and 2% wheat bran to the Azotobacter,Bacillus phosphaticum or Bacillus mucilagionsus solution can significantly improve the shelf life of these solutions.Under the same condition,compared with the control group,the shelf life of Azotobacter can be extended to over 12 months and the shelf life of Bacillus phosphaticum is more than doubled in micro-organicsolutions that use unpasteurized peat as the carrier,when add 4% molasses,2% wheat bran and 2‰-4‰ sodium benzoate as well as 0.5‰-1.0 ‰ carbendazim,the shelf life is extended by at least 50% over that of the control group.
