Description

Liquid foliage fertilizer and production method thereof

Technical field:

The present invention relates to the production field of a kind of foliage-spray with liquid fertilizer.

Background technology:

Liquid fertilizer as a kind of novel efficient compound fertilizer, has the following advantages: use producing (1), dust can not occur in the transportation, and smog pollutes few; (2) product does not exist moisture absorption and agglomeration problems; (3) can with sterilant, sterilant, herbicide mixture and mixing, (4) can not resemble solid fertilizer and produce segregation in accumulating, quality is uneven; (5) application process is various, can foliage-spray, and Sui Shuichong executes, also can sprinkling irrigation, drip irrigation or pouring, easy to use, cost saving, it is fast to produce effects; So liquid fertilizer is one of trend of world today's industrial development.The nineties in 20th century, the annual liquid fertilizer that consumes of the U.S. accounts for more than 38% of chemical fertilizer total quantity consumed.China's development liquid fertilizer is later, because the application of foliar nutrient and drip irrigation technique, liquid fertilizer is developed rapidly.Particularly the plantation of protection ground is as booth vegetable, melon and fruit, cash crop etc., and liquid fertilizer is easy to use, effective, is subjected to the favor of wide farmers.But the technical barrier that always can't resolve in the liquid fertilizer for a long time.Because phosphoric acid salt solubleness is low, available nutrient content surpasses 20% and easily separates out crystal under the normal temperature, the proterties instability, and therefore, the nitrogen phosphorus potassium effective constituent of existing liquid fertilizer all is lower than 20%, and the domestic market contains the liquid fertilizer of effective composition more than 30% and can't realize.And the classification of compound manure, all effective contents are called the high-concentration compound fertilizer material greater than 30%, are lower than 20% value that loses compound manure, because of nutrient content is too low, influence result of use, not welcome by the peasant, and transportation, management, production, cost of use strengthen.On the other hand, add trace element in the liquid fertilizer, can not accomplish generally speaking, produce precipitation, influence proterties and result of use because of trace element in zinc, boron, manganese, the calcium etc. is mixed mutually each other or with phosphoric; And use the EDTA complexing agent to solve the interpolation problem of trace element, and cost an arm and a leg because of this complexing agent again, be difficult in the actual production promote.

Summary of the invention:

At the practical problems that above-mentioned prior art exists, the invention provides the high-content clear liquid type liquid foliage fertilizer of a kind of boracic, zinc microelement.The invention still further relates to its production method.

Technical scheme of the present invention is: this kind liquid foliage fertilizer is characterized in that formulated by the following weight proportion raw material: in per 1000 parts of fertilizer, 230 parts of solid ammonium polyphosphates, molecular formula are K ₂HPO ₄3H ₂300 parts of the dipotassium hydrogen phosphates of O, 20 parts in urea, 430 parts in water, molecular formula are Na ₂B ₈O ₁₃4H ₂12 parts of the four water eight borate two sodiums of O, molecular formula are ZnSO ₄7H ₂5 parts of the Zinc Sulphate Heptahydrates of O, add 3 parts of plant-growth regulator sodium nitrophenolates after the water mixing dilution, the ratio 1:3 of sodium nitrophenolate and water.

The production method of fertilizer of the present invention is:

(1), 20 parts in urea, solid ammonium polyphosphate are dissolved in 190 parts of water for 230 parts;

(2), four water eight borate two sodium is dissolved in 40 parts of water for 12 parts;

(3), Zinc Sulphate Heptahydrate is dissolved in 20 parts of water for 5 parts;

(4), dipotassium hydrogen phosphate is dissolved in 180 parts of water for 300 parts;

(5), sodium nitrophenolate and water presses the 1:3 dissolving, gets 3 parts;

(6), with step (2), (3), (4), (5) confected materials set by step sequencing join successively to mix in the solution of step (1) and get final product.

Solid ammonium polyphosphate material dissolution degree height, the resiliency selected for use are strong, micro-metals is effective in complexing, the chelating, has the function that fertilizer buffer reagent and complexing agent have both, can solve in the liquid fertilizer and to add trace element and produce sedimentary problem, make the adding of trace element in the fertilizer become possibility because of elements such as zinc, boron, manganese, calcium are mixed mutually each other or with phosphoric.Dipotassium hydrogen phosphate nutrient content height, solubleness height.Four water eight borate two sodium disperses in water soon, and instant under the cold water state, solubleness height, nutrient are polymeric form, can not cause fertilizer damage, easily by plant absorbing.

The invention has the beneficial effects as follows:

1, liquid fertilizer total nutrient content height, also contain the crop normal growth and educate required water soluble trace elements boron, zinc, proportioning science, can supply with the crop full nutrition, product does not have precipitation, does not have flocculation, can mix with the water arbitrary proportion, CL, can not produce impurity, can not stop up shower nozzle, crop absorption rate height.

2, select the solid ammonium polyphosphate for use, energy buffered soln potential of hydrogen avoids fertilizer damage to produce, and multiple metallic cations such as energy chelating zinc, boron, calcium, magnesium can be used with other big-and-middle microelement foliage fertilizers, sterilant, sterilant, avoid precipitation to produce, easy to use, raise the efficiency.

3, select four water eight borate two sodium for use, boron content height under the cold water state, can be dissolved into rapidly in the water, and plant absorbing is fast, and the utilization ratio height is compared the generation that can reduce boron harm with other boron fertilizer.

4, add the sodium nitrophenolate growth regulator, can regulate the absorption rate of plant, promote plant-growth, strengthen the plant vigor, improve product quality fertilizer.

5, the product fertilizer efficiency is stable, effective, fertilizer efficiency is fast, is applicable to different ecological type district and various crop.

6, product performance are stable, non-crystallizable in the time of-3 ℃, do not flocculate, do not precipitate, non-volatile more than 40 ℃.

7, easy to use, safe, environmentally friendly.

8, this fertilizer nitrogen, phosphorus, potassium total nutrient content reach more than 38%, proportion 1.38, and nutrient uraphetine g/L, and add trace element zinc, boron and plant-growth regulator in right amount.This fertilizer color yellow, as clear as crystal, supply with plant nutrition comprehensively, and coordinate plant growth, promote to get agricultural profit.

Through this liquid fertilizer of evidence more than a year, can supply with crop alimentary comprehensively, can be big or middle, trace element fertilizer, sterilant, sterilant use with other.Absorption rate is fast, improves plant recovery of nutrient.Can promote plant growth, well developed root system with 800-1000 times of foliage-spray this product of this product dilution, strengthen disease-resistant anti-adversity, improve product quality, and can dilute 2500-3000 times of drip irrigation, dash and execute.One fertile multipotency, fertile many usefulness, easy to use, save cost, raise the efficiency.
