Description
Technical field
The present invention relates to a kind of organic fertilizer special and preparation method thereof, special-purpose fertilizer of particularly a kind of desert and desertification treatment and preparation method thereof.
Background technology
The improvement of desert and desertification is the key subjects of China's ecological environmental protection and improvement.1,700,000 square kilometres of China's existing desert areas account for territory total area 18%, and are annually also increasing with 2460 square kilometres speed.If add Gobi desert and ccd area, the total area accounts for about 30% of territory total area.China desert and desertification present situation have threatened our living space at present, and administering desert and desertification is that we need long-term constant project of vital and lasting importance of making great efforts.
For many years, China has carried out a large amount of research and improvement work in desert and desertification treatment, but does not find optimal sand control way at present as yet.Traditional sand control is simple kind of the grass of planting trees, because sand itself does not have coherency, strong wind one blows, and often sapling is pulled up, and grass-seed is blown away, and therefore traditional desertification control method gets half the result with twice the effort often, can't be in the improvement that fundamentally realizes desert and desertification.
Summary of the invention
The purpose of this invention is to provide special-purpose fertilizer of a kind of desert and desertification treatment and preparation method thereof, it can improve soil physico-chemical property, and sand is had cohesion, plays and protect soil, protects effect fertile, 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, has therefore fundamentally solved the problem that traditional desertification control method is difficult for fixing the sand.
For achieving the above object, the invention provides the special-purpose fertile preparation method of a kind of desert and desertification treatment, comprising:
The preparation ammonium humate;
Weight percent is the ammonium humate of 80-95%, monoammonium phosphate, diammonium phosphate or double superhosphate that weight percent is 3-10%, weight percent is 2-10% vitriolate of tartar or Repone K thorough mixing is even, or be that the ammonium humate of 80-97% and potassium primary phosphate thorough mixing that weight percent is 3-20% are even with weight percent;
Said mixture is crushed to 70-90 order fineness.
Described preparation ammonium humate is specially:
Leonardite is ground into the leonardite powder of 80～300 order fineness;
With weight percent is the described leonardite powder of 50-70%, bicarbonate of ammonia, the water thorough mixing resulting mixture that weight percent is 15-30%;
Described mixture was heated 1-3 hour down at 50-70 ℃;
Seal described mixture 5-10 days.
Also comprise step after the described mixture of sealing: the described mixture after will sealing was dried 1-3 hour down at 50-80 ℃, made its water content less than 15%.
The leonardite powder that described leonardite is ground into 80-300 order fineness is specially: the leonardite powder that described leonardite is ground into 100-150 order fineness.
The heating under 50-70 ℃ of described mixture was specially in 1-3 hour: described mixture was heated 2 hours down at 60 ℃.
Sealing described mixture 5-10 days is specially: seal described mixture 7 days.
For achieving the above object, the present invention also provides a kind of desert and the special-purpose fertilizer of desertification treatment, it is made up of following raw materials by weight percent: ammonium humate 80-95%, monoammonium phosphate, diammonium phosphate or double superhosphate 3-10%, vitriolate of tartar or Repone K 2-10%, or form by following raw materials by weight percent: ammonium humate 80-97%, potassium primary phosphate 3-20%.
Described 80-95% ammonium humate is made up of following raw materials by weight percent: leonardite powder 50-70% and bicarbonate of ammonia 15-30%.
The invention provides special-purpose fertilizer of a kind of desert and desertification treatment and preparation method thereof, have the following advantages:
1, special-purpose fertilizer can improve soil physico-chemical property.The special-purpose fertilizer of the present invention has very strong bonding effect to sandy soil, execute soil and can form crumb structure, execute the desert and can play cohesion the desert, make surface layer of desert form one and solidify duricrust, strong wind just can blown sand like this, played and protected soil, protected fertile, water retention, can increase nitrogen, phosphorus, potassium content in the sandy soil simultaneously.
2, special-purpose fertilizer can improve the viability that greening changes husky crop.The special-purpose fertilizer of the present invention has intensive corrosion mineral ability, can make the indissoluble nutrient in the sandy soil become solubility, is beneficial to crop and absorbs; And the root system to greening sand control crop has the stimulating growth effect, thereby makes greening change the well developed root system of husky crop, fixes the sand drought-resistance ability to strengthen.
3, special-purpose fertile preparation method is simple.Preparation method of the present invention is simple, does not need special processing units to produce, and is convenient to penetration and promotion.
4, production cost is low, the economic benefit height.China bicarbonate of ammonia source is abundant, cheap, is one of comparatively ideal raw material; The present invention has then fundamentally solved the problem that traditional desertification control method is difficult for fixing the sand, and has improved the economic benefit of desert and desertification treatment.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
