Description
Technical field
The present invention relates to a kind of biological organic fertilizer containing oxalic acid and preparation method thereof, belong to technical field of biological organic fertilizer.
Background technology
Biological organic fertilizer does not contain only abundant organic matter, possibly together with a large amount of active microorganisms, for probiotics, due to bacterium
The occupation time process of group, reduces disease and occurs；Biological organic fertilizer contains function bacterium and organic matter, can improve soil and promote by soil solid
Determine the release of nutrient；The utilization of soil fixing fertilizer is promoted by function bacterium；The organic matter of biological organic fertilizer inherently merit
The environment of energy bacterium life, easily survives after being manured into soil.
For the improvement in salt-soda soil, chemical method has preferable effect, and chemical modifying applies some bisalts exactly
Material improves the character in salt-soda soil, reduces the acid-base value of soil, increases the cation replacement ability of soil, reduces containing of soil
Salt amount, strengthens Soil Microorganism and the activity of enzyme, promotes plant root growth.Improve the physical property of soil, increase soil
Crumb structure, coordinates soil water lump at the left hypochondrium heat, increases soil fertility.
Existing biological organic fertilizer has the disadvantage that
(1) quality is very different, there is the phenomenons such as effective bacterial content is low, miscellaneous bacteria exceeds standard, and also some producer adds in bio-feritlizer
Enter an inappropriate amount of chemical fertilizer or other additive, make that nitrogen inorganic in fertilizer, phosphorus, potassium content are too high causes effective bacterium dead, and lose
Go the effect of bio-fertilizer；
(2) to heavy metal lead in alkaline land soil without obvious reducing effect；
(3) for alkaline land improving, it is impossible to effectively reduce soil salt content simultaneously, reduce soil pH, improve soil moisture content,
Improve soil water retention hole, reduce alkalization of soils degree, increase Nitrogen In Soils phosphorus potassium content；
(4) plantation of Helianthi in salt-soda soil, Helianthi transplanting survival rate is low, and main root is shorter；Capitate diameter is little；
Yielding poorly of sunflower seeds；Empty grain rate is high；
(5) plantation of Helianthi in salt-soda soil, prevents or preventive and therapeutic effect without obvious the soil-borne disease of Helianthi.
