First-distilled wood vinegar: used for skin management (allergic skin, athlete's foot, etc.), re-distilled wood vinegar: used as a food additive, beverage, etc., for agricultural purposes, it can restore soil fertility, improve cultivation, and save chemical pesticides , chemical fertilizers, restoring moisture and other effects.
Wood vinegar is a pure natural substance distilled from perennial oak wood through high temperature. Its main components are organic acids and phenolic substances. In order to clarify the effects of wood vinegar and its main components on soil microorganisms, Organic fertilizers with different doses of wood vinegar, guaiacol, and acetic acid were applied to the soil, and changes in the number of microorganisms in the soil were observed. The results showed that: add 10g of wood vinegar to 1kg of organic fertilizer and apply it to 30kg of soil. The number of soil microorganisms (especially the number of bacteria) increased the most, and soil microorganisms were effectively activated within 10 days; at the same time, when the amount of wood vinegar added to 1kg of organic fertilizer was as high as 50g, it had a certain inhibitory effect on soil microorganisms. In addition, , through a comparative test using the two main components of wood vinegar, acetic acid and guaiacol, it was shown that its impact on the number of soil microorganisms is incompatible with that of wood vinegar.
Vinegar has many uses. 1. Soil improvement Spraying wood vinegar solution into the soil can prevent blight of seeds and can also be used as a soil disinfectant. Applying bamboo vinegar to the soil can effectively inhibit the reproduction of microorganisms that hinder plant growth and kill root nodule nematodes and other pests. 2.

Wood vinegar is generally made from various miscellaneous tree branches, unused branches cut from orchards, etc., which are simmered in a charcoal kiln to produce smoke and condense the natural gas into a liquid. The quality is good. However, discarded furniture containing high resin content such as coniferous trees, casuarinas, and paint are not allowed to be used. The liquid obtained by condensation is crude wood vinegar, which needs to be refined to remove undesirable components before it can be used. The main component of wood vinegar liquid is vinegar.

Efficacy: (1) Increase the vitality of crop roots and leaves, slow down aging, reduce fruit acidity, extend fruit storage time, and improve flavor. (2) Prevent and control some diseases and insect pests on the soil and leaves, and promote the reproduction of beneficial soil microorganisms. (3) Accelerate the fermentation rate of compost.
