Description

A kind of novel reinforced nutrient green " LB " fertilizers

Technical field

The present invention relates to modern agriculture advanced production data field, be specifically related to a kind of initiative of the nutrient green fertilizers that is rich in various trace elements.

Background technology

One or more essential trace elements absorptions of the puzzlement nearly half of world population (approximately 3,000,000,000 population) are at present unbalance, cause chronic disease (as heart trouble, cancer, apoplexy and diabetes etc.) to present trend occurred frequently.But people are difficult to find and be familiar with the problem of micro-insufficiency of intake conventionally.For tackling this global healthy crisis, some countries and regions have been taked to carry out trace element interpolation in diet and have been waited nutritional fortification measure, and more preferably mode is supplemented by meals.But due to the pollution of environment, the excessive use in the lavishment of chemical fertilizer and soil etc., cause Trace Elements in Soil disappearance, skewness and Crop low, thereby, to the strengthening means of farm crop employing nutrition and the health-promoting factor.Wherein, most economical, the most simply, the most effective and continuable mode is: the green functional fertilizer of using the effect of tool nutrient-reinforced.

In meals, the real source of nutrient imbalance is that agrosystem can not continuously, sufficiently provide essential nutrients and health factor-micro elements needed by human.And agricultural and nutrition department are also never using agricultural as the powerful that resists nutrient imbalance relative disease.But the harsh fact makes many developing countries, also comprise that development country recognizes that the caused health problem of the low inferior reason of Trace Elements in Soil skewness, disappearance and Crop has become main public health problem.Therefore, increasing the validity of the current essential trace element still lacking (as, iron, iodine, selenium, zinc etc.) and improve the nutrition of agricultural-food, crop, is first the trophic level of soil.Wherein, initiative nutrient-reinforced green functional fertilizer, being applied to soil is the most effective most economical and continuable effective measure, increases corps nutrient level not changing in farm crop genomic constitution situation.

The lifting of corps nutrient level, effectively solves Nourishment level, and then overcomes micronutrient element unbalance of human body.Therefore, increase the micro-element nutrition level of farm crop, primary is the micro-element nutrition level that promotes soil, under current Agricultural land envrionment conditions, only has the green functional fertilizer by be rich in various trace elements to soil application, with reinforced soil nutrition.

Although trace element only accounts for 9/10000ths in crop ash content, even 100,000/several, and constant, moderate-element nitrogen, phosphorus, potassium, calcium, magnesium etc. occupy 99%, and it is but vital to biological effect.These trace elements are to promote photosynthesis mostly, the enzyme of respiration and Substance Transformation effect etc. or the integral part of coenzyme, be the active centre of doing in object and animal body, have single-minded physiological function, in the growing process of crop and life, effect greatly.

In the time that some trace element in soil is not enough, crop just there will be deficiency disease shape, as apple tree iron deficiency, and young sprout yellow.Lack zinc, newly slightly leaf is little; The yellow of grape iron deficiency spire, it is light yellow that cob is.Grape calcium deficiency, blade is yellowish green, have macula lutea, lacks zinc and forms leaflet; Particularly food crop, wheat iron deficiency, blade takes off yellow death, lacks copper heading and is obstructed, and seed forms restricted; It is yellow that paddy rice boron deficiency blade tip is, and withered, lacks zinc, and tillering phase, new leaf base turned white, browning in Lao Ye edge.

Only, with regard to boron, crop is to boron sensitivity mostly, and boron deficiency is to plant growth, and especially on fruit impact greatly, but excessive boracic can be poisoning, affects equally the results of plant growth and fruit.Boron has special physiological function to crop, but different from other trace elements, is not the integral part of enzyme, but have special trophism, borate family is like phosphoric acid salt, and the OH reaction in energy and sugar, alcohol and organic acid forms boric acid ester, thereby, there is transportation and the metabolism of (1) participation carbohydrate; (2) promote building up and growing of reproductive organ; (3) oxidation system in control agent; (4) nitrogen fixing capacity of raising root nodule bacterium; (5) elongation and the division of promotion cell; (6) promote the running of nucleic acid and protein synthesis, growth hormone and improve crop drought resistance ability etc.Thereby the disappearance of boron is excessive almost to be had more deep associated with all compounds.

Soil is the main source ground of the required trace element of crop.In soil, always contain the trace element of different sorts and different quantities, some not necessarily crop need, also not necessarily Crop utilize form, therefore, must supplement by using trace element fertilizer.Nanjing Soil Inst., Chinese Academy of Sciences provides the result of study (as following table) that judges its deficiency according to the content of various trace elements in crop leaf

The rich scarce index of micro element content (unit: mg/kg) in crop leaf

Although the required trace element amount of crop seldom, in the ordinary course of things, in plant materials, only have ten thousand/several to 100,000/several (10-4-10-5), be equivalent to only contain in the plant stem body of 1 kilopond the trace element of 1-10 micrograms (1-10 μ g/kg), but crop still can produce micro-deficiency disease.Reason has three: the amount of application of (1) N, P, K chemical fertilizer is large, and crop yield significantly improves, and has taken away on the one hand more trace element from soil.Crop increases with the raising of N, P, K chemical fertilizer application level the ratio of absorption of trace elements on the other hand.Thereby, there will be trace element to supply with the phenomenon of relative deficiency; (2) impact of soil chemical properties on giving property of trace element, except molybdenum (Mo), most of trace elements are subject to the impact of soil pH value and have occurred to the different trend with changing of property, as just more active at acid soil in zinc (Zn), copper (Cu), boron (B), iron (Fe), generally exist with water-soluble state or replacement property, giving property is more intense, thereby, crop grows in the soil that contains these elements, can not produce deficiency disease.But, for the popularization of the agrotechnical measure to soil transformation, can have a significant impact (reduction) to property to soil trace element.As improve a large amount of limings of acid soil, and increase the alkaline matter in soil, make can obviously declining to property of most of trace element, occur that bringing out property of trace element lacks problem.So, in the time of liming improvement acid soil, suitably use trace element fertilizer; (3) mutual relationship between trace element, cause some trace element deficiency, as having antagonistic action between phosphorus (P) and zinc (Zn) or copper (Cu), at phosphorus (P) rich content or use in a large number in the soil that phosphorus (P) is fertile, will there is to lack zinc (Zn) or scarce copper (Cu) phenomenon.At this moment,, if be affixed by zinc (Zn) fertilizer or copper (Cu) fertilizer, just have obvious effect of increasing production.

Some main micronutrient elements, if iodine (I) is the anti-oxidant function of wisdom element, selenium (Se), the hematopoiesis physiology biological nature that zinc (Zn) tool helps the effect of growing, iron (Fe), significant equally to plant, most important to the mankind's health.

Therefore, in current agricultural planting activity in production: (1) excessive use chemical fertilizer; (2) N, P, K fertilizer proportional imbalance; (3) application process and fertilizer variety are selected improper technical matters, follow the basic theories of the rational application of fertilizer, use functional green fertilizer, simultaneously, adopt advanced fertilizer practice and technique, realize and improve crops quality and the target that promotes corps nutrient level.

Wherein, rational application of fertilizer basic theories and sophistication are most important.

1, the basic theories of the rational application of fertilizer

1) nutrient is given back and is learned opinion.The nutrient theory of returns that French scientist Li Bixi proposes, it is the basis of agricultural being regarded as to exchange of substance between the mankind and nature, the nutritive substance that namely absorbs and assimilate from soil and atmosphere by plant, absorbed as food by human and animal, through excremental corruption and the decomposition course of animals and plants self and animal, return to again in the earth and atmosphere and go, completed material and given back, shown agricultural biomass exchange basis.In addition, must give back the material that picked-up is walked to the earth, the mode of giving back is applied fertilizer exactly, otherwise, can affect soil fertility, impact is produced normally.

2) minimum nutrient rule

Due to nutrient situation difference in soil, fertilization effect is different.This is the height because of crop yield, and soil, for crop requirement, is restricted by the minimum nutrient of content (being minimum nutrient).This rule is also that French scientist Li Bixi proposes.Main points are: what (1) determined crop yield is the nutrient of relative content minimum in soil; (2) minimum Nutrient condition changes and changes, and minimum nutrient, owing to enriching specific aim fertilizer, makes crop yield, but now minimum nutrient is no longer minimum, and with condition, variation has occurred; (3) lack specific aim, do not contain minimum nutrient composition if enrich in fertilizer, not only do not increase production, run counter to desire on the contrary.

3) law of diminishing return

Law of diminishing return is that 18 th century later European economy scholar's Turgots and Anderson propose simultaneously, it is a ubiquitous rule of economics, prerequisite is under agriculture production steady state, and fertilising is controlled variable, has two main points: (1) increases ultimate production with rate of fertilizer application and increases; (2) units increased in production of fertilising increase, unit fertilizer, i.e. the remuneration of fertilizer is reducing gradually.What emphasize here is rational science consumption.

4) factor integration effect rule

Be subject to, under composite factor prerequisite, to emphasize active limiting factor.Its main points are that (1) crop high yield is the result of all factor integration effects; (2) utilize the interaction in comprehensive action between the factor to improve fertilizer efficiency.For example, apply fertilizer and irrigate each tool effect, if combination, effect of increasing production is greater than the two independent effect sum.

2, advanced technology and measure

1) determine rate of fertilizer application with method of fertilization for target yield.The method using the difference of required realize target output nutrient and soil supply amount of nutrients as determine rate of fertilizer application foundation, to reach nutrient budget balance, therefore, method of fertilization for target yield claims again nutrient balance method, calculating formula is as follows:

$F=\frac{(Y\×C)-S}{N\×E}$

Wherein: F: amount of application (kg/ha);

Y: target output (kg/ha);

C: unit output nutrition absorption amount (kilogram);

S: soil supply amount of nutrients (kg/ha) [based on soil nutrien measuring value × 2.25(reduction factor) × soil nutrient utilization coefficient];

N: nutrient content (%) in institute's fertilise;

E: fertilizer this season utilization ratio (%).

2) the new measure of modern fertilising

(1) spray multielement micro-fertilizer (or use polynary base manure and topdress)

Multielement micro-fertilizer contains the required various weight element nutrients of various crop, not only comprehensive trace element supplement nutrient, but also the balance of embodiment nutrient is supplied with.

(2) fertigation

Because fertigation is that fertilizer enters soil with irrigation water, there is fertilizer efficiency fast, easily absorb, save water, fertile resource, save labour, the advantage of soil protection structure.

(3) carbonic acid gas (CO2)

In warm canopy, enrich CO2 fertilizer, improve photosynthesis effect, just can form the simplest carbohydrate---monose by chlorophyll.Under chemical equation is:

Under the effect of corresponding enzyme, plant can also utilize monose for raw material, synthetic more complicated disaccharide, and starch or conversion fat, also can participate in the metabolism of nitrogen, further synthesizing amino acid, protein.

In addition, fertilizer practice method mainly contains:

1, soil application.Make base manure, seed manure or topdress to be manured into soil, though utilization rate of fertilizer is low, aftereffect is better.For saving fertilizer, general employing spreaded manuer in holes and row replacement.

2, seed treatment.Comprise seed soaking and seed dressing.

3, foliage fertilization, sprays.

4, dip the seedling root in.Be used for transfer farm crop, as paddy rice etc.

Summary of the invention

In order to address the above problem, the object of the invention is to propose a kind of novel reinforced nutrient green " LB " fertilizers.

For achieving the above object, technical scheme that the present invention adopts is as follows:

A kind of novel reinforced nutrient green " LB " fertilizers, this fertilizer comprises 13 kinds " LB " material being rich in 14 kinds of essential nutritional trace elements of human body and animal, and take " LB " material as base-material or auxiliary material, the compound Bulk Blending Fertilizer of assembly plant growth nutritive substance N, P, K.

Further, described " LB " material is rich in 13 kinds of trace elements that iodine, selenium, zinc, iron are representative.

Further, also comprise " non-traditional mineral manure " and assembly N, P, the fertile manufacture of the compound blending of K (B, B) that " LB " material is raw material.

The present invention is directed to the great demand that this affects human health, formulated two kinds of two kinds of multi-Functional Fertilizers that are rich in trace nutrient (trace element).One is to adopt to be rich in 14 kinds of needed by human micronutrient elements " LB " material of 13 kinds and to be machined directly to " the micro-fertilizer of non-traditional mineral "; Another kind is material take " LB " material as base (auxiliary), the compound blending of assembly plant growth nutritive substance (N, P, K) processing (B, B) fertilizer.

The present invention utilizes 13 kinds of features that " LB " material contains in 14 kinds of needed by human nutritional trace elements take iodine, selenium, zinc, iron as representative (wherein also to contain the essential boron of crop, its important feature), for crop nutritional deficiency phenomenon, formulate nutritional fortification green functional fertilizer system.Be specially and produce two types of fertilizer:

1, the micro-fertilizer of non-traditional mineral.Because " LB " material itself is rich in 13 kinds in 14 kinds of crop and needed by human nutritional trace elements, and its material property is silicate, with soil be homogeneity, homology, as the supplier of various trace elements, itself be trace element fertilizer-" the micro-fertilizer of non-traditional mineral " of high-quality.Its application meets the rational application of fertilizer " factor integration effect rule ".

2, to utilize " LB " material be base (auxiliary) material and the crop desired nutritional material assembly such as N, P, K, can, according to the fertile feature of same-action need not, produce multiple specific aim fertilizers.

Use with apply fertilizer by science, reach rescuing crop nutritional deficiency disease.

To sum up, content of the present invention is two: one, " LB " material preparation technology technique, " the micro-fertilizer of non-traditional mineral " is manufactured, its two, blending (B, B) the fertilizer formula design of material take " LB " material as base (auxiliary).

Embodiment

Describe the present invention in detail below in conjunction with specific implementation method, be used for explaining the present invention in exemplary embodiment and description of the present invention, but not as a limitation of the invention.

Embodiment 1:

1, minimum plant element nutritional trouble and Diagnosis of Deficiency

1) minimum plant element nutritional trouble disease

Plant nutrition deficiency disorder comprises two kinds of nutritive deficiency and overnutrition (poisoning) diseases.In agriculture production, occurring maximum is plant nutrition deficiency disease, also claims plant nutrition nutritional deficiency disease.Wherein, it is increasing that in current agriculture production, micronutrient element lacks area, and this is because (1) crop yield is higher, and the micronutrient of taking away is just more; (2) N, P, K fertilizer amount increase, and the unbalancedness of having aggravated micro-supply becomes the important restriction factor that crop yield improves; (3) organic fertilizer consumption reduces, and micronutrient is difficult to be supplemented.Due to the expansion gradually of this plantation (work) thing trace element nutritional deficiency disease, the decline of crop failure and product quality will be affected.

For this phenomenon, from the angle of the fertilizer science of nutrient balance and balance fertilizing, in enriching N, P, K chemical fertilizer, science is used micro-fertilizer by an important Fertilization Decision that is 21 century.

2) Diagnosis of Deficiency

(1) planting (work) thing nutritional deficiency is physiological disturbance

Trace element disappearance is physiological disturbance for planting (work) thing.Cause poor growth, yellow leaf, deformity, even fallen flowers bud drop; Peanut iron deficiency causes chrysanthemum disease; Fruit tree lacks zinc and causes little leaf disease; Rape boron, blooms shaky; Tomato boron deficiency, except stem flavescence, also possibility blackening of centre portions; Cauliflower lacks molybdenum, and leaf is by macula lutea browning look, and tomato lacks molybdenum, and fallen flowers increase etc.

(2) diagnostic method

1. outward appearance diagnosis

Leaf look be the most obvious nutritional deficiency symptom of plant extremely.Generally be divided into first yellow (minus green) and on blade, produce the large class of various spots two.For example, the deficiency diseases such as iron, manganese, zinc, copper, because element is difficult for moving in plant materials, thereby, come across spire more; Molybdenum deficiency disease, due to the existence of molybdic acid negative ion, deficiency disease shows as first and occurs at the next Lao Ye and meta leaf.

2. diagnose according to edaphic condition

● pH value

Normally 5-8. is along with more than pH value exceedes neutrality to the pH value of ploughing, and the solubleness of essential element generally declines, and just there will be deficiency disease, and take iron, manganese, copper, zn deficiencie as main, iron deficiency occurs that yellows are the most outstanding; If pH value is down to below 5 in soil, wherein, manganese, aluminium are because solubleness increases, and element surplus, poisons and produce.

● redox state

The element that valency changes can occur, and when when carry out redox in soil, valency changes, solubleness also changes thereupon.Fe+3 and Mn+4 solubleness are low, if be reduced to Fe+2 and Mn+2, solubleness increases, so paddy field rice Fe+3 and Mn+4 are reduced to Fe+2 and Mn+2, and than dryland rice and wheat class, is not prone to iron deficiency, manganese deficiency disease.

● moisture state

Soil exchangeable manganese is significantly less than air dried condition under many wet conditions, and this is because soil water molecule is combined with manganese, improves degree of hydration, and manganese is become can not be to due to state.Facts have proved in some cases, soil water state is one of reason causing trace element deficiency.

● organism

The amount of soil organic matter and confrontation trace element can bring various impacts to degree.

Easily a large amount of existence of decomposing organic matter can promote soil reduction process, promote the dissolving of iron, manganese; Some small organic molecule has sequestering action, insoluble metal that can chelating stripping, and can form complex body with trace element, to insoluble conversion;

On the other hand, sometimes there is manganese in extreme organic soil or peat soil, copper lacks.For example, the northern area that oat graywall occurs of Holland, is that acid sandy peat and alkaline clayey soil join band mutually, and the dispersion of soil organic matter makes trace element dissolve the complicated result of generation.

● coexisting ion

Lack with element or superfluous relevant be " can to state " amount in soil, there is physiological working in coordination with and antagonistic action in interionic in addition, therefore, the essence of coexisting ion is its amount containing.There is selenium-rich soil in North America big area, suppresses by using vitriol.In addition, mantoquita can suppress the absorption of herbage to molybdenum, and these have all utilized antagonistic action between coexisting ion.

3. do object analysis

In the time can becoming component to increase to state in soil, Crop amount also increases certainly thereupon.In crop there are several stages in concentration of element: along with doing the rising of concentration of element in object, Development And Yield progressively increases, and this is the shortage stage that crop does not absorb normal fertility aequum.After this, maintain bulk concentration, and make Development And Yield increase (absorbed dose also increases), this is the suitable stage that keeps bulk concentration to grow.If along with soil concentration improves and absorbs surplus, finally there is obstacle, growth declines on the contrary, and this relation is all set up in principle on any element, any crop.

If the threshold concentration can regulate and control from the shortage stage to the suitable stage, from the suitable stage to superfluous phase transition time, facilitates to do and lacks, superfluous diagnosis.Formula fertilization by soil testing will address this problem.

2, fertilization compositions based on earth measurement

Be related to the well-being of the people, the rich and powerful and social stability of country for grain security, fertilising acts on up to 40%-50% in increases in grain production, and chemical fertilizer blindly and the serious negative effect brought of excessive use, No. 1 file of the Central Committee of the Communist Party of China in 2005 clearly proposes to promote Formula fertilization by soil testing, becomes one of the of paramount importance national science and technology action in recent years of China's agriculture field.

" the surveying native formula fertilizer technical specifications " of printing and distributing revised in March, 2007 by the Ministry of Agriculture, lasted so far 8 years.Current, the sport technique segment of the many keys in fertilization compositions based on earth measurement makes a breakthrough, and set up the region of " large formula, little adjustment " and joined fertilizer technology, and the native formula work of in-depth survey, form comparatively perfect basic fundamental route (key work) at present.

Formula fertilization by soil testing is mainly around " survey soil, fill a prescription, join fertilizer, fertilizer instruct " five links with carry out, 11 work such as " field study, sampling are surveyed and executed, field test, formulating of recipe, formula processing, Demonstration And Extension, advocacy and training, database establishment, natural Productivity Evaluation of Cultivated Land, effect assessment and technical research ".

Patent content of the present invention follows Ministry of Agriculture's " Formula fertilization by soil testing standard " and correlation technique route is implemented.

3, product manufacture

1) non-traditional mineral manure technology of preparing and technique

(1) ore dressing and purification

Because the raw material mineral (being called for short raw material mineral) of " LB " material are affected by build environment, and association has rhombspar, calcite, illite, quartz and a small amount of heavy mineral.In addition, high purity " LB " material feedstock mineral are less, and middle low grade ore is in the majority, thereby, need ore dressing, purification.Conventionally adopt dry technique technique and Wet technique technique.

Law technology technique

Raw ore, through pulverizing, classification, is processed as particulate material or powder.Particulate material granularity is 270 μ m(50-48, μ m-300 orders); Powder granularity is 45 μ m(325-200, μ m-75 orders).

Dry method ore dressing purification processing technical matters flow process is: raw ore → picking → dry → fragmentation → ore grinding → classification → packing.

The key operation of its processing is abrasive dust and classification.45-75 μ m products generally adopt rolling suspension disintegrating machine (Raymond mill), and tornado feeder set carries out classification." LB " material feedstock mineral contain hard ore particle (as quartz etc.), are difficult for grinding.Can remove by " size abandons " of selecting tornado feeder set.Because the sorting result of dry method ore dressing purification techniques technique is limited, so being only applicable to ore quality, the method better or to quality product requires very not high situation.

2. Wet technique technique

Wet technique technique is pulverizing mineral, on classification basis, by smashing the process flows such as slurry dispersion → processing → dehydrate, complete the processing of the product that " LB " material purity is had relatively high expectations, as the application in feed, fodder additives and part substitute antibiotics.

" LB " material feedstock mineral are crystallite mineral, need to be prepared as even ore pulp or finely disseminated suspension before purification, " LB " material mineral and impurity particle are fully disperseed, and impose the stirring of high shearing.Disperseing fully, is the basic of high efficiency separation impurity.

Conventional processing equipment is hydrocyclone, horizontal centrifuge, shaking table etc.

" LB " material feedstock mineral are silicate, and it is to be relatively easy to separating of non-silicate, but larger with the separating difficulty of similar mineral.For example montmorillonite and " LB " material mineral are that structure is close, be easily mutually and the mineral of symbiosis, and density and the disseminated grain size of two kinds of mineral are close, thereby separation must be taked unconventional method.

By purifying, soil, crop (comprising) needed by human nutritional trace element have also obtained enrichment, can be used as " non-traditional mineral manure " and directly use.

(2) acid treatment

Acid-treated object is to remove the impurity such as acid-soluble carbonate, promotes purity, increases its specific surface area, improves decoloring ability.Acid used is mainly the mineral acids such as hydrochloric acid, sulfuric acid and nitric acid or uses separately, or mixed.Aspect of performance hydrochloric acid is better than sulfuric acid, and cost aspect sulfuric acid is better than hydrochloric acid.

Acid treatment is acid activation, the concentration of purity that the principal element that affects its usefulness is mineral, granularity, chemical composition and acid, solid-to-liquid ratio, soak time etc.

(3) thermal treatment (calcining)

" LB " material feedstock mineral are heated to≤measure 200 ℃, lose planar water; At 200 ℃ of-400 ℃ of temperature lower calcinations, can greatly improve the absorption property of mineral, its mechanism is that the zeolite water in planar water and the structure pore between mineral fibre is removed, and inside and outside specific surface area significantly increases event.And along with temperature raises, specific surface area progressively increases, during to 252 ℃, be maximum, after this, along with temperature raises, specific surface area sharply declines on the contrary.The relation that " LB " material feedstock mineral specific surface area changes with Heating temperature is as following table:

Calcining temperature/℃	Do not burn	130	200	250	320	400
							Dehydration %	0	8.5	10.0	12.5	16.7	18.9
Specific surface area (BED) m2g-1	71.1	2.7	268	320	282	241

2) production of the related bulk blended fertilizer of expecting take " LB " material as base (auxiliary) of patent of the present invention is according to the production technique processing and manufacturing of " blended fertilizer " of composite fertilizer (B, B fertilizer).
