Description
Technical field
The invention belongs to field of chemical technology, be specifically related to a kind of compoiste fertilizer and preparation technology thereof.
Background technology
The improvement of Desertification is the key subjects of China's ecotope and improvement.The existing desert area of China 1,740,000 square kilometres, accounts for territory total area 18%, and is also increasing with the speed of 3460 square kilometres every year.If add Gobi desert and ccd area, the total area accounts for about 30% of territory total area.Current China Desertification present situation has threatened our living space, and Desert Control and desertification are that we need long-term constant projects of vital and lasting importance of making great efforts.
China's prolonged drought lack of water, desertification of land enlarged areas, fertility is poor, productivity is low, and nutrient is barren, be difficult to vegetation, ecological degradation, environmental degradation.At present, the fertilizer that China agriculturally uses is mostly single character and simple function, i.e. inorganic quick-acting chemical fertilizer, can only as topdressing, and shortage can supplement soil organism nutrient, culture fertility on producing, can conserve water and soil again, Meteorological effect, can also tackling quicksand, improvement sand ground multifunctional ecological compoiste fertilizer, for China's desertification desert treatment and deteriorate grassland Revegetation.
In recent years, although also have the sand fixation material of development and the sand control technology of exploitation both at home and abroad, be mostly simple function technology or product, and expense is large, cost is high, effect is not ideal, is difficult to large scale application.Because various technology is well integrated, be difficult to play comprehensive advantage, the improvement of desertification desert local, the overall situation worsened are not reversed.Defend and control sand in the past and return forest department to manage, lay particular emphasis on afforestation and check winds and fix drifting sand, but sand ground Shamian Island completely can not be planted tree, natural situation the sand and dust of sandy land surface can be kicked up from the space of trees once blowing and form hazards of sand storms.Afforestation and desertification control because of trees " stop " sandstorm compared with grass " sealing lid " sandstorm be used for much smaller.
Therefore, urgently need to research and develop and a kind ofly can supplement soil nutrient, culture fertility, can conserve water and soil again, water conservation and moisture-holding, sand ground, the high-content of tackling quicksand and long-acting slow-release effect, Multifucntional compoiste fertilizer can also be improved and be applicable to novel ecological fertilizer that the drought resisting of dry Wind-sandy Area, the herbage vegetation of fixed nitrogen and eco-environment restoration keep and technology mode.Be applied to Chinese desert arid area and foster and apply fertilizer in soil, industrial and mineral Subsided Reclamation Region, ecological reconstruction, the ground soil conservation of sandy beach, river and improvement, deteriorate grassland Revegetation and maintenance.
Summary of the invention
The object of this invention is to provide a kind of Ecological organic composite fertilizer and preparation method thereof, it can improve soil physico-chemical property, has cohesion to sandy land, plays the effect of sand-fixation soil-retention, fertilizer conservation, water conservation; It can also stimulate greening to change the growth of husky crop root simultaneously, strengthens the drought-resistance ability that fixes the sand that greening changes husky crop, therefore fundamentally solves the problem that traditional desertification control method cost is high, not easily promote.
For achieving the above object, the invention provides a kind of Ecological organic composite fertilizer and preparation method thereof, be made up of the raw material of following weight percent: ammonium humate 80-90%, xylose powder 10-15%, double superhosphate 1-3%;
Described ammonium humate is made up of the raw material of following weight percent: brown coal powder 65-75% and urea 8-12%, bicarbonate of ammonia 15-25%, clear water 1-15%, well-mixed mixture.
Described xylose powder, refers to the sodium lignosulfonate powder utilizing wheat straw pulping back liquor to prepare.
Its preparation method is:
Step one, prepare ammonium humate:
Brown coal powder is broken into the brown coal powder of 120 ~ 350 order fineness;
Be the described brown coal powder of 65-75% by weight percent, the urea of 8-12%, the bicarbonate of ammonia of 15-25%, 1-15% clear water fully mix;
Said mixture is heated 3-5 hour at 60-70 DEG C;
By said mixture airing 5-15 hour.
Mixture 5-10 days after sealing airing.
Again the described mixture after sealing is dried 3-4 hour at 60-75 DEG C, make its water content be less than 10%, obtain ammonium humate.
Step 2, to prepare gained ammonium humate weight percent be 80-90% ammonium humate by above-mentioned, adds the xylose powder of 10-15%, the double superhosphate of 4-7% fully mixes; Said mixture is crushed to 90-110 order fineness.
A kind of Ecological organic composite fertilizer provided by the invention and preparation method thereof has the following advantages:
1, Ecological organic composite fertilizer can improve soil physico-chemical property.Compoiste fertilizer of the present invention has stronger bonding effect to sandy soil, and executing soil can increase soil aggregate, improves porosity status; Spray application to desert and can play cohesion to desert, make surface layer of desert form an ecological film, such strong wind just can blown sand, serves soil conservation, fertilizer conservation, water retention, can increase nitrogen, phosphorus, potassium content in sandy soil simultaneously.
2, Ecological organic composite fertilizer can improve the viability of vegetation crop.Compoiste fertilizer of the present invention has strong corrosion mineral ability, the indissoluble nutrient in sandy soil can be made to become solubility, be beneficial to Crop; Soil cationic absorbent performance can be improved, increase soil fertilizer ability; Soil buffer performance can be improved, improvement edatope.And have stimulation growth to the root system of vegetation crop, thus make the well developed root system of vegetation crop, fix the sand drought-resistance ability strengthen.
3, Ecological organic composite fertilizer preparation method is simple.Preparation method of the present invention is simple, does not need special processing units to produce, is convenient to penetration and promotion.
4, Ecological organic composite fertilizer production cost is low, high financial profit.China's brown coal, urea, bicarbonate of ammonia, double superhosphate abundance, cheap, be comparatively ideal raw material; The present invention then fundamentally solves traditional desertification control method and not easily fixes the sand, with the technical problem of vegetation, to improve the economic benefit of desert treatment.
Below specific embodiments of the invention are described further.
