Bran acetic acid that is not salt of the initial fermentation acid, the general consumption of acetic acid plant can provide. I try to replace bran acid acetic acid instead of citric acid, dissolved ferrous sulfate medium, the effect of citrus deficiency iron deficiency was significantly welcomed by the fruit growers. Now the specific methods are described as follows: 1. Fermentation in the septic tank, the formula is: high quality human and animal manure 30 picks, the concentration of 10 degrees (fecal gravity table determination); cabbage dry 6 kg; ) 2.5 kg; 1.3 kg of ferrous sulfate (the amount of formula to treat 10 yellowing trees). Ferrous sulfate is first dissolved in bran acetic acid, poured into the pool with the manure water, stir well, and then sealed septic tank, fermentation can be used for 13 days, this time fermentation broth
