Point.Animals and plants remains such as lignins, under microorganism and geophysics, chemical action, through a series of decomposition and
Convert the class macromole organic monoacid mixture formed.Humic acids is not a single acid, but complicated containing
There is the mixture of the group such as carboxyl, phenolic hydroxyl group, so this mixture shows the character of binary acid or ternary acid once in a while.Rotten
Phytic acid is usual and ion forming complex in nature.
Humic acids, as organic matter raw material, is widely used in agriculture, woods, herds, oil, chemical industry, building materials, medicine, defends
The every field such as life, environmental protection.Now belong to direct or indirect application humic-acid-type substances has five aspects, can be summarized as 70
Individual trifle.The major product of China's exploitation has fertilizer, pesticide, veterinary drug, drought resistance agent, feed additive；Medicine, health care
Product, cosmetics；Petroleum assistant, industrial water conditioning agent, coal water mixture stabilizing agent, accumulator extender, ceramic additive,
More than 100 kind such as easer, has basically constituted the integral framework of China Humic Acid series products.
Humic acids is divided into humic acid, ulmic acid, fulvic acid, wherein humic acid proportion by dissolubility and molecular size range
Maximum, its molecular weight is maximum, more than 105The order of magnitude, is dissolved in alkali and water insoluble, sour, ethanol and acetone；Hymatomalenic acid
Molecular weight is relatively big, is 104-105The order of magnitude, is dissolved in alkali, ethanol and acetone；Fulvic acid molecular weight, is 103The order of magnitude,
It is dissolved in acid, alkali and water.In these three component in addition to fulvic acid, humic acid, ulmic acid be transformed into potassium, sodium equivalent metal or
Ammonium salt can be dissolved in water, the aobvious alkalescence of these saline solutions.And fulvic acid can be directly dissolved in water, its aqueous solution is faintly acid.
CN103275333A discloses a kind of crop material and extracts class humic acids and compound fertilizer's preparation method thereof, by extracting
Humic acids in Semen Ricini stalk straw and fulvic acid, optimize the utilization rate of resource, indirectly decreases Semen Ricini stalk straw to ring
The pollution in border, meanwhile, the compound fertilizer utilizing the class humic acids extracted to prepare can improve the production environment of crop, for crop
Growth provide more nutrient, strengthen crop resistance.
CN101040622 discloses a kind of preparation side utilizing straw to produce composite humic acid plant growth regulator
