Abstract
Biological fulvic-acid urea relates to a fertilizer. The invention aims to solve the technical problem of low utilization rate of urea due to leaching loss and volatilization. Biological fulvic-acid urea is composed of biological fulvic acid and urea, wherein mass content of biological fulvic acid is 0.01-20% and mass content of urea is 80-99.99%. As biological fulvic acid has high active groups, when biological fulvic acid is combined with urea in different forms, complexation can be formed such that fulvic-acid urea has a certain slow-release effect and utilization rate of the fertilizer is increased by 15-30% and above. It can be known through field test data that output of crops is not reduced when 25% of urea is reduced. Under the condition of the same urea use-amount, yield increase of biological fulvic-acid urea is 5-15% higher than yield increase of common urea.
Description
Technical field
The present invention relates to a kind of fertilizer.
Background technology
With agricultural crop straw, reed and timber as primary raw material, using soda pulping process, major pollutants in slurrying are the black liquor of boiling, therefore it is key link to administer black liquor, and black liquor of pulp making is converted into the high powder containing fulvic acid and amino acid by using complex microorganism, and after testing its fulvic acid content reaches 77.59g/L, ulmic acid content reaches 10.0g/L, up to 1.35 g/L, up to 88.94 g/L, amino acid content is up to 15.428 g/L for fulvic acid total amount for humic acid content.Understand that its main component is fulvic acid by data, the biological humic acid that the method is produced is compared with the fulvic acid that other are originated, and its condensation level and carbon content are relatively low, molecular weight, and active group is more, lighter color, good water solubility, easily passive plant absorption is utilized.
Urea is the nitrogen fertilizers being currently mainly used in agricultural, because the impact of the factor such as leaching loss and volatilization can not fully absorb utilization using crop, at present, the utilization rate of China's nitrogenous fertilizer is only 30～35%, phosphate fertilizer 10 ~ 25%, potash fertilizer 40～50%, less than 15～20 percentage points of developed country.Annual about 900～15,000,000 tons of the chemical nitrogen by the loss of the approach such as leaching, volatilization, about 350～60,000,000,000 RMB of value, cause the wasting of resources, agriculture production cost increase, environment and pollution of agricultural products, quality of agricultural product decline and the destruction of serious ecological environment.According to investigations, more than 60 are had in more than 130 large-size lake of China to suffer including the severe contamination including eutrophication, are improved chemical fertilizer utilization ratio and are had become the major issue for being related to national economy.
For the urea for delaying to be lost because of leaching loss or volatilization, improve the utilization rate of urea, those skilled in the art have done substantial amounts of research work, for example, in sulfur-coated urea, the resin-bonded grinding wheel to materials such as urea outer wrapping one layer of sulphur, resins, or urease inhibitor and nitrification inhibitor etc. are dosed in urea, on the one hand these new ureas need newly-built production line, another aspect cost of material is also higher, and these all increase substantially cost, so as to affect penetration and promotion.Therefore research and development process is simple, the obvious new-type fertilizer of with low cost, effect become the direction made great efforts needed for current scientific and technical personnel at different levels.
The content of the invention
The present invention in order to solve due to leaching loss and volatilization cause the low technical problem of the utilization rate of urea, there is provided a kind of Biological humic acid urea.
Biological humic acid urea is made up of biological humic acid with urea, and wherein the mass content of biological humic acid is 0.01%～20%, and up to 0.04 ~ 10%, up to 0.05 ~ 10%, the mass content of urea is 80%～99.9 % to humic acid content to ulmic acid content.
The using method of humic acid urea of the present invention is identical with common urea, for the plantation of grain, vegetables, industrial crops and fruit.
Biological humic acid can preferably improve the drought-resistant ability of crop；Various enzymatic activitys and chlorophyll content of plant can be preferably improved, makes metabolism vigorous；Absorption and running ability of the plant to trace element can preferably be improved；Fertilizer efficiency can be dramatically increased compared with chemical fertilizer is re-dubbed organic-inorganic composite fertilizer, chemical fertilizer is reduced and is fixed and be lost in, improve the utilization rate of chemical fertilizer, and play the role of improved soil.
Because biological humic acid has higher active group, therefore complex reaction can be formed when biological humic acid is combined in different forms with urea so that humic acid urea has certain slow releasing function, the utilization rate for making fertilizer improves more than 15～30%；By field test data, crop does not have the underproduction when usage amount for reducing by 25% urea is used；In the case of equal amount of urea, Biological humic acid urea is than common urea volume increase 5～15%.
