Description
Technical field
The present invention relates to a kind of production methods for improveing salt-soda soil novel bio-organic fertilizer, belong to soil amelioration techniques neck
Domain.
Background technique
The salinization of soil and Secondary Saline problem are worldwide widely present, it has also become world's Irrigation farming can be held
The resource constraints of supervention exhibition.About 23,400,000 hm of China's saline alkali land area2, northwest, North China, West of The Northeast China and coastal region are equal
It is distributed, and type multiplicity.Improvement, develop and utilize saline alkali land resource, can be relieved due to population be continuously increased cause population with
Contradiction between soil to holding agricultural sustainable development, is improved the ecological environment, thrust zone economy, society and ecological sustainability
Development is of great significance.
Due to northern China Arid Region salt-soda soil due to rainfall is few and evaporation capacity is big, water source supply is insufficient causes
Regional alkaline land improving, using extremely difficult.Chemical improvement agent is used on saline-alkali soil, is improved using acid-base neutralization principle
Salt-soda soil physicochemical property is that alkaline land improving is the most frequently used and most efficient method.Chemical improvement agent has two aspect effects: first is that changing
Kind soil texture accelerates the process of desalinization of soil by flooding or leaching row's alkali；Second is that changing soluble-salt based component, increase base exchange capacity, adjusts soil
Earth pH value.
The green culture and education of China Agricultural University award developed in 2005 it is a kind of using easy, effect is obvious and low-cost
Alkaline land modifying agent-" Kang Dibao " soil conditioner.Wang Wenjie, He Haisheng will improve the soil in 2005 getting fat, take husky pressure alkali, kind
Tree planting wood etc. tradition modification method combined with soil conditioner improves salt-soda soil, by different soils depth salts alkalis dynamics with
And endemic species tree planting plants the upgrowth situation of poplar to inquire into the feasible method for improveing local heavy salinized ground Poplar Plantation woods.Research
The result shows that soil conditioner polymaleic anhydride (HPMA) can make salt-soda soil pH value and salt content bright under resistance salt agent barrier
Aobvious decline, and growth of poplar rate is higher, and improved effect is significant.With the progress of agricultural science and technology technology, people are constantly opened
Some low-cost soil conditioners are sent out and develop, these soil conditioners newly developed can make up high polymer soil and change
Good dose of price is higher, is difficult to the shortcomings that promoting, but these soil conditioners still have improvement cost it is excessively high, soil transformation period
Too long technological deficiency.The present invention is intended to provide a kind of production method for improveing salt-soda soil novel bio-organic fertilizer, not only
It can solve the pollution problem of agricultural byproducts processing waste, can more turn waste into wealth, there is good economic significance and reality meaning
Justice.
Patent application 201510603623.2 provides a kind of alkaline land improving fertilizer, is made of the raw material of following parts by weight:
20~40 parts of soluble humic acid, 5~15 parts of amino acid, 5~10 parts of organic matter, 7~15 parts of complex microorganism, flyash 10~
15 parts and 13~27 parts of grass meal of mixing, wherein the complex microorganism is by nitrogen-fixing bacteria, hay bacillus and bacillus licheniformis group
At.Patent application 201410461007.3 is related to a kind of fertilizer for saline-alkaline field, is prepared from the following raw materials in parts by weight: humic acid
5~20 parts, 0.3~1 part of microorganism, 6~16 parts of farmyard manure, 15~40 parts of stalk, calcium superphosphate, ferrous sulfate, flyash, chaff
Aldehyde slag and desulfurized gypsum account for 5~10 parts, 6~14 parts of nitrogenous fertilizer, 2~4 parts of phosphate fertilizer, 2~3 parts of potash fertilizer altogether；Above two method or salt
Alkali modifying agent all to salt-soda soil have preferable improved effect, but effect be difficult to continue, improvement process it is slow, soil improvement effect
Fruit is still unsatisfactory.
Summary of the invention
In order to overcome in the prior art soil conditioner cost it is excessively high and improvement the slow technical deficiency of process, the present invention
A kind of production method for improveing salt-soda soil novel bio-organic fertilizer is provided, this method is original using animal wastes and crop material
Raw material is digested by way of deodorizing process and biological organic matter fermentation and obtains intermediate product, intermediate product and humic acid by material
Deng forming bio-organic fertilizer after the fertilizers are mixed.The bio-organic fertilizer significantly can persistently reduce the pH in salt-soda soil.It is described
