Embodiment
Both containing also having higher carbon back content compared with high humic acid content in leonardite, compare with other organic productss, leonardite is rich in humic acids.The one that brown coal are through 7,000 ten thousand years humic acids processes and are formed interrupts product.The ecologic active of brown coal is equivalent to 5 times of other humic-acid-type substances, namely 1 kilogram of leonardite is equivalent to the organic raw material of 5 kilograms of other humic acidss, 1 kg liquid humic acids is equivalent to 7-8 tons of organic chemical fertilizer humic acids content, and the humic-acid-type substances 1 kilogram of same powdery is equivalent to the humic acids content in 30 tons of chemical fertilizer.Therefore brown coal are selected to prepare active humic acid as raw material in the present invention.
Humic acid is to the action principle of soil:
1. improve the characteristic of soil
The calcium ion generation complex reaction easily and in soil of hydroxyl in humic acids, carboxyl, then the crumb structure of soil is just defined by the physiological action of root system of plant.When the crumb structure of soil improves, its unit weight reduces, voidage increases, thus possesses good permeability.Humic acids is again the important jointing compound forming soil aggregate, and the formation of soil aggregate improves the organic and inorganic multiplicity of soil, adds water stability big particle agglomerate quantity, improves the structure of the soil body.Therefore, humic acids can improve the physical property of soil.Humic acids is other organic materialss relatively, improve soil physical property aspect and have some superiority.Use the growth that humic-acid kind material can promote crop root, make farm crop form huge deep layer root system, be conducive to the adjustment of soil Zhong Shui, fertilizer, gas, thermal conditions, be conducive to Crop moisture, nutrient.Meanwhile, water conservation, fertilizer conservation effect of humic acids are conducive to growing of crop, and then improve the output of crop.
2. improve the characteristic of soil fertility
Because humic acids is a kind of acidic substance, to be reacted by acid-base neutralisation and cation and anion exchange effect can reduce the pH value of saline-alkali soil, reduce the share of exchangeable sodium ion in soil, activation nutrient ion, thus reach the effect improving soil fertility.Existingly report, present in the soil of alkalescence after using the weathering coal dust accounting for soil quality l0%, the pH value of soil reduces 1 unit by original 9.0.
3. improve soil organisms vigor
There is a large amount of microorganism in soil, the forming process that these microorganisms take part in soil is again the important component part of soil, makes soil have certain biologos.Soil microorganisms contamination can be used as 1 index reflect soil quality condition.The Main Function of soil microorganisms promotes the effectuation of soil nutrient and the formation of crumb structure, and the soil after microorganism improvement, again for microorganism provides good living environment, is conducive to its amount reproduction.The elements such as C, N, P contained by humic acid substance are that soil microorganisms provides the existence energy, after soil application humic acid substance, first soil azotobacter is significantly increased, and the content of NO is obviously increased, enrich the N element nutrition of soil, improve plant rhizosphere environment; Secondly, increase the quantity of aerobic bacteria, actinomycetes, cellulose-decomposing bacteria in soil, improve organic mineralization velocity, promote the release of nutrient element; Further, the activity of sucrase, proteolytic enzyme, polyphenoloxidase all increases in soil.
Below in conjunction with specific examples, set forth the present invention further.
