Description
Technical field
The invention belongs to agricultural fertilizer technical field, and in particular to a kind of enhancing legume-rhizobium mutualism
Biomass fertilizers and its application.
Background technology
China is large agricultural country, and legume plantation mainly has soybean, peanut and broad bean etc., is China's vegetable edible oil
Main source, the nitrogen that rhizobium are fixed up to 68% of ammonium fertilizer needed for legume growth, do not apply fertilizer by traditional planting patterns.
Because China's most area multiple crop index is higher than 2, stalk is by direct on-site incineration for many years, and not only waste of resource, pollution are big
Gas, soil hardening, also the growing environment of the microorganisms such as rhizobium in soil, fungi is done great damage, in recent years part agriculture
Family makes up the nutrient deficiency problem triggered by rhizobium by destruction, but pulse family by every mu of composite fertilizer for increasing 10kg or so
Crop yield and quality still decline year by year, and particularly Huang-Huai-Hai is especially serious, have threatened China's modern material reserve
Sustainable development.
As non-regeneration energy crisis increasingly sharpens, biomass generation develops rapidly in China, and the current whole nation is about
400 biomass electric power plants, biomass ash is produced per year up to more than 16,000,000 tons, processing mode is simple landfill or leased land heap at present
Put, ambient atmosphere, soil, water are caused seriously to pollute, while cause about 480,000 tons of K every year2O, 640,000 tons of active SiO2, 200,000
ZnO and 6.6 ten thousand ton of B of ton2O3Deng a large amount of wastes of precious resources.
Biomass ash pH value 10~13, main component are the oxides of the elements such as Si, Ca, Mg, Fe, Cu, Zn, Mn, B, this
Dvielement be plant growth must and the middle trace element that lacks in soil.If biomass ash, which is largely added in fertilizer, can cause ammonium
State nitrogenous fertilizer decomposes, it is impossible to produces high nitrogen fertilizer material, strongly limit its extensive use in fertilizer.
Ammonium lignosulphonate is a kind of aromatic compound with complexing, pH value 4~5, is xanthohumic acid kind fertilizer
One of quality raw materials.
The A of patent CN 105967840 utilize the production of the raw materials such as black liquid, sulfuric acid solution, bone meal, brown sugar residue, nitrogen-fixing bacteria
Microorganism fertilizer, the granulated fertilizer with some strength how is made after not specifying slurry-spraying pelletizing, can ensure have in fertilizer largely
Active rhizobium are worth discussion.And because it is the microorganism fertilizer using organic matter as carrier, rhizobium are not to add height
Nutrient fertilizer.
Pyroligneous acid is the caused mixture containing a variety of fragrant same clans during straw charring, has sterilization, controls worm, be anti-
Disease；Beneficial microbe activity in soil is improved, there is complexing function to promote plant growth effect, can be used as green, non-harmful
Micro- fertilizer uses, and improves crop yield and quality.
Bone soup is discarded object caused by various bones are processed, and concentrated concentrate to 40%, containing abundant protein, is
Promote the high-quality natural medium of microbial reproduction.
Legume mainly obtains nutrient by biological nitrogen fixation, and traditional planting patterns is not applied fertilizer, due to big portion of China
Region-by-region multiple crop index is higher than 2, and stalk is by direct on-site incineration for many years, not only waste of resource, pollutes air, soil hardening,
Also the growing environment of the microorganisms such as rhizobium in soil, fungi is done great damage, part peasant household is few by increasing in recent years
Amount composite fertilizer makes up because rhizobium are by the nutrient deficiency problem triggered is destroyed, and it is intrinsic to change legume-rhizobium
" mutualism " nutrient supply mode, has threatened the sustainable development of China's modern material reserve.
The processing of standard biologic matter ash is stacked for landfill or leased land at present, and serious dirt is caused to ambient atmosphere, soil, water body
Dye, while cause about 480,000 tons of K every year2O, 640,000 tons of active SiO2, 200,000 tons of ZnO and 6.6 ten thousand ton of B2O3Deng the big of precious resources
Amount wastes.
