Description
The present invention relates to fertilizer field, more particularly, relate to comprehensive compound fertilizer of a kind of nutritive ingredient and manufacture method thereof.
Existing fertilizer is divided into inorganic fertilizer (chemical fertilizer of nitrogenous, phosphorus, potassium etc., mineral manure etc.), fertilizer (comprising organic commercial fertilizer and farm manure etc.) and several big classes of bacterial manure substantially.Wherein, the advantage of bacterial manure is that consumption is few, instant effect, short long effective.But shortcoming is its production and the very strict technical qualification of service requirements, is difficult for grasping for vast farmers, and it preserves also relatively difficulty, and price is rather stiff, so the use of bacterial manure still fails to be in full swing in the vast rural area of China so far.Simultaneously, when using bacterial manure, the necessary nitrogen of plant-growth, phosphorus, potassium etc. also will lean on inorganic fertilizer or fertilizer to provide, and is therefore also cumbersome.The advantage of inorganic fertilizer is the content height of effective quick-acting compositions, farm crop are to the utilization ratio height of effective quick-acting compositions, but the kind of its effective quick-acting compositions less (common compound fertilizer also do not comprise can by the 6-8 kind effective constituent of crop absorption), therefore can not satisfy comprehensive needs of farm crop, when the life-time service inorganic fertilizer, can cause soil progressively barren, cause the farm crop anti-adversity poor, make the downgrade of agricultural-food.Particularly under the situation that multiple crop index increases year by year for many years, above-mentioned situation is even more serious.The advantage of fertilizer is that effective quick-acting composition is more comprehensive, can strengthen the anti-adversity of farm crop, improves the quality of agricultural-food, and can improve and protect soil, increases fertility of land.But its shortcoming is that the total content of effective quick-acting compositions is lower, and the absorption of farm crop is slower, and effect of increasing production is not remarkable.And the source of fertilizer is comparatively limited, can't satisfy the needs in vast rural area.
The objective of the invention is to provide a kind of compound complete smart fertilizer that can have the advantage of above-mentioned a few class fertilizer concurrently and can overcome its shortcoming.
The inventor finds after through long-term deep research, plant comprehensively in the necessary element of growth, and not only three kinds in nitrogen, phosphorus, potassium far away, for example, in major element, calcium, magnesium, sulphur are also very important to the growth of plant; And in trace element, rare earth element can also strengthen the anti-adversity ability of farm crop significantly except the growth that can promote farm crop.Other a lot of trace elements can both play good promoter action to the growth of plant.On the basis of this research, the inventor has found a kind ofly contains nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, rare earth (mixing), silicon, boron, iron, copper, sodium, zinc, manganese, aluminium, germanium, lithium, chromium, selenium, strontium, chlorine, cobalt, molybdenum, the titanium compound fertilizer prescription of totally 24 kinds of compositions, and the preparation method of this compound fertilizer.Use compound fertilizer of the present invention, farm crop are increased production significantly, and can strengthen its anti-adversity ability significantly.And can improve and protect soil, increase fertility of land, thereby can guarantee the volume increase year after year of farm crop.Because this discovery, thereby finished the present invention.
That is to say, the invention provides a kind of compound fertilizer, it is characterized in that it contains following ingredients:
