Description
Technical field
The present invention relates to agricultural fertilizer technical field, in particular to a kind of salt-soda soil special-purpose multifunctional compound fertilizer and its preparation side
Method.
Background technique
China is the widely distributed country of saline-alkali soil, and there are more than 500,000,000 mu of saline and alkaline soils in China, and it is raw that salt affected soil is unfavorable for plant
It is long.China has 17 provinces, municipalities and autonomous regions to be dispersed with salt-soda soil at present, is mainly distributed on northwest, North China, northeast and coastal area,
Be transformed salt-soda soil and improve salt-soda soil farm output it is extremely urgent.
Salt-soda soil is mainly characterized by containing more water soluble salt or alkaline matter.Since salinity is more in soil, alkalinity
Greatly, the soil organism is destroyed and is lost, and microelement is in great shortage, is glued when showing as wet, hard when doing, and native table often has white saline and alkaline
Precipitating ventilates, is permeable bad, and crop root system often has poisoning, rotten, the phenomena of mortality.Applying a large amount of fertilizer in this way can not
The phenomenon that being absorbed and utilized by crops, causing high investment, low output.Fertilizer dedicated to alkaline land currently on the market is single
The alkalinity of soil is improved, retain water and nutrients that can not be permanently effective are " palliative ".
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of retain water and nutrients, the salt-soda soil of improvement soil physico-chemical property
Special-purpose multifunctional compound fertilizer.
The present invention also provides the preparation methods of the salt-soda soil special-purpose multifunctional compound fertilizer.
The purpose of the present invention is realized by following technical solution:
Salt-soda soil special-purpose multifunctional compound fertilizer, is made of the raw material of following parts by weight: nitro humus acid particle 20-40

Part, 10-30 parts of nitrogen-phosphorus-potassium compound fertilizer, 2-6 parts of binder；
The modifying agent is the weight by ethylene diamine tetra methylene phosphonic acid sodium and diethanol monoisopropanolamine according to 1:0.2-0.5
Than what is be mixed to get；
The binder is that attapulgite clay and sodium cellulose glycolate are mixed with weight ratio 1:1.
The duckweed slag is prepared by following methods: green duckweed, EM composite bacteria agent, water thrown into fermentation vat,
Anaerobic fermentation 10 days under the conditions of 30-35 DEG C, drying in the air to water content is 20%, obtains duckweed slag.
The magnetic bio charcoal is prepared by following methods:
1) by charcoal 80 mesh of sieving, charcoal particle is obtained；Pickling charcoal particle removes surface impurity, adds to diethyl
In glycol solution, the mass ratio of charcoal particle and diethylene glycol solution is 1:60, and ultrasonic 5min obtains charcoal solution；
2) ferric acetyl acetonade is added in charcoal solution, the mass ratio of ferric acetyl acetonade and charcoal particle is 1:1, is surpassed
Sound 10min, magnetic agitation, which is led under nitrogen state, is heated to 180 DEG C of reaction 1h, continues to be heated to 260 DEG C of reaction 20min, obtain magnetic
Charcoal.
The partial size of the nitro humus acid particle is 1-5mm, pH 3-5.
A kind of salt-soda soil special-purpose multifunctional compound fertilizer, is prepared by following methods:
1) modifying agent, magnetic bio charcoal, high hydroscopic resin and nitrogen-phosphorus-potassium compound fertilizer are uniformly mixed, obtain material 1；
2) by nitro humus acid particle, citric acid waste, duckweed ground-slag are broken and binder is uniformly mixed, obtain material 2；
3) material 2 is divided into 2-5 parts, first adds to first part of material 2 in material 1, mixing machine mixing obtains material 3；
4) second part of material 2 is added in material 3, mixing machine mixing obtains material 4；
5) and so on, the mixing of 2-5 material is carried out, until material 1 and material 2 are uniformly mixed；
6) uniformly mixed material 1 and material 2 are granulated through pelletizer；
7) granular fertilizer is dried in dryer, it is cooling, it sieves, it is multiple to can be prepared by salt-soda soil special-purpose multifunctional for packaging
Complex fertilizer.
Beneficial effects of the present invention:
1) citric acid waste in salt-soda soil special-purpose multifunctional compound fertilizer of the invention and duckweed slag can be improved with chesson
The physical structure of soil reduces the pH value of soil；Modifying agent can form multiple monomer structure macromolecular nets with chelated metal ions
Shape complex compound improves the infiltration coefficient of soil；The addition of nitro humus acid particle further increases the buffer capacity of soil, inhibits
