Description
Technical field
The invention belongs to the agricultural fertilizer technical field, relate to a kind of humic acid liquid fertilizer, relate in particular to the multi-functional humic acid liquid fertilizer of a kind of stability and high efficiency type.
Background technology
Chemical fertilizer becomes increasingly conspicuous to the production-increasing function of crop.The statistics of the World Food Programme (FAO) shows, 20th century world food output 40%-60% from the contribution of fertilizer.But at present along with urbanization process is accelerated, cultivated area and Quality Down, population increases rapidly simultaneously, and world per capita cultivated land is 0.4 hectare, and China's per capita area of cultivated farmland is 0.1 hectare only, and Food Security becomes world subject.The existing effect of conventional fertilizer in agriculture production is undeniable, and utilization ratio is not high, and fertilizer loss is serious, and its environmental problem of bringing is paid attention to by countries in the world.Liquid fertilizer is favored take characteristics such as its multielement high-efficiency, compound customizations, long acting multifunction and environmental protections as the agricultural producer.Humic acids is at " five greatly effect " on the agricultural (improvement soil, synergy chemical fertilizer, stimulating growth, enhancing is degeneration-resistant and improve quality), xanthohumic acid " four doses of functions " (drought resistance agent, growth regulator, pesticide slow-release synergistic agent, chemical element complexing agent) on agricultural etc., humic acid liquid fertilizer has become the important member of new liquid fertilizer family, widespread use in China's agriculture production.
At present, in humic acid liquid fertilizer products production and the application, there are the following problems: 1. micellar system is unstable, is prone to flocculation, precipitation, and various nutrients are non-constant.2. during lesser temps, easy salting-out crystallization, nutrient density homogeneous.3. auxiliary component science not easily causes blade injury, and blade face plate-out ability and imbibition are poor, and fertilizer efficiency is poor, and utilization ratio is not high, is unfavorable for that crop increases.4. functional single, the nutrient component is science not.
Summary of the invention
The objective of the invention is to overcome the technical deficiency of existing liquid fertilizer product, provide a kind of stability and high efficiency type multi-functional humic acid liquid fertilizer.
Another object of the present invention provides the preparation method of the multi-functional humic acid liquid fertilizer of this stability and high efficiency type.
The invention provides a kind of humic acid liquid fertilizer, it is prepared from by following component by weight:
Potassium fulvate 10-20 part,
Macroelement 35-45 part
Trace element 10-15 part,
Solubility promoter 1.0-1.5 part
Stablizer 0.2-0.4 part
Penetration-assisting agent 0.3-0.5 part
Natural surface active agent 0.8-1.5 part
Degeneration-resistant startup agent 1.0-2.0 part
Growth stimulant 0.06-0.1 part
Water 25-33 part.
Preferably, be prepared from by following component:
13 parts of potassium fulvates,
40 parts of macroelement
11 parts of trace elements,
1 part of solubility promoter
0.2 part of stablizer
0.4 part of penetration-assisting agent
1 part of natural surface active agent
1.0 parts of degeneration-resistant startup agent
0.06 part of growth stimulant
32.4 parts in water.
Wherein, described macroelement is urea, ammonium polyphosphate and vitriolate of tartar, and its weight ratio is 1.0-4.5: 1.0-2.5: 1.0-3.0.
Described trace element is selected from one or more in Zinc Sulphate Heptahydrate, iron vitriol, manganese sulfate monohydrate, cupric sulfate pentahydrate, ten water boric acid and the four water ammonium molybdates.
Described solubility promoter is glycerol.
Described stablizer is Xylo-Mucine or xanthan gum.
Described penetration-assisting agent is organosilicon or organic fluorine (unstable alveolitoid).
Described natural surface active agent is selected from a kind of in sorbitol, mannitol, Sorbitol Powder, erythritol, maltose alcohol, the Saccharum lactis.
Described degeneration-resistant startup agent is L-Leu.
Described growth stimulant is tetramethyl-pentanedioic acid (TGA).
The present invention also provides the method for the above-mentioned humic acid liquid fertilizer of preparation, may further comprise the steps:
1) first solubility promoter part and stablizer are added together abundant stirring 10-15 minute, add again water and be stirred to evenly, form A liquid.
2) fulvic acid potassium, macroelement and trace element are added in the A liquid successively, under steam heating 50-60 ℃ condition, chelatropic reaction 3-5 hour, non-shock chilling 8-10 hour, form B liquid.
3) degeneration-resistant startup agent, growth stimulant, penetration-assisting agent and natural surface active agent are added in the B liquid successively, stir, use the lemon acid for adjusting pH value to 6.0-6.5, and get final product.
Humic acid liquid fertilizer of the present invention mainly carries out foliage-spray, also can fill with root, dip in root, seed dressing, soaks seed and soak the various ways such as cutting and use.
Each component that fertilizer of the present invention comprises has following characteristics: the fulvic acid potassium that 1, is rich in belongs to low molecular mass humic acids, have stronger chemically reactive and physiologically active than humic acids, but complexing is micro-, reduce the nutrient antagonism, improves the nutritive element utilization ratio; Improvement soil, stationary state nutrient in the activating soil; Activate soil microbial activities; Promote crop photosynthesis, regulate respiration, improve the root of hair vigor; Improve the crop anti-adversity energy; Improve crops quality; Less objectionable impurities is polluted, is ensured food safety.2, the phosphorus source is ammonium polyphosphate, not only is beneficial to the crop Foliage Absorption, can prolong the moistening time of blade face simultaneously, prolongs crop to the soak time of nutrient.3, overcome multiplex Tween-80 in the existing liquid fertilizer product, PEG400, the chemical classes such as SDS and OP-10 tensio-active agent is to the injury of plant leaf, utilize natural surface active agent glycitols material among the present invention, effectively reduce the crop leaf surface tension, the plate-out ability of element has additional nutrients, glycitols material self molecular mass is low, be easy to be absorbed by blade, participate in the adjusting of cell inner penetration and raising to the resistance of active oxygen, make crop adapt to the adverse circumstance growth, in also being, the good complexing agents such as trace element, and can carry mineral nutrient and in plant phloem, transport, effectively reduce simultaneously urea to the damage of crop leaf.4, micellar system is stablized: stablizer Xylo-Mucine or xanthan gum, and the suspension degree of increase liquid reduces the humic acid liquid fertilizer precipitation and produces, and assurance humic acid liquid fertilizer all technical is stablized; Decrease salt eutectoid temperature enlarges use range.5, nutrition absorption is rapid: penetration-assisting agent organosilicon or organic fluorine, ooze and absorption in the acceleration available nutrient, and can significantly improve fertilizer utilization efficiency.6, strengthen resistance: degeneration-resistant startup agent L-Leu, precursor as " stress ethylene " promotes material, promotes to produce endogenous hormones ethene under the environment-stress effect, opens the Secondary Metabolism of Plant approach, the metabolism of accelerating aromatic series and monoterpenes compound is synthetic, strengthens crop anti-adversity.7, Effective Raise yield and quality: growth stimulant tetramethyl-pentanedioic acid (TGA), the energy rapid permeability is in plant materials, the involved in plant protein metabolism promotes the protoplasma of cell to flow, and breaks seed dormancy, accelerate plant rooting speed, stem increases slightly, extends, and blade enlarges, and leaf green content improves, less fallen flowers, shedding improve product quality.
Fertilizer of the present invention has following beneficial effect: have stable micellar system, nutrient homogeneous, equilibrium, component science, can significantly improve fertilizer utilization efficiency, promote plant growth, strengthen resistance, improve many-sided characteristics and the effects such as crop yield and product quality.Field test by 2 years shows (seeing Table 1), and liquid fertilizer of the present invention can make vegetable crop improve 9.04%-20.11%; Food crop volume increase 7.15%-11.01%.
