Description
Technical field
The present invention relates to the technical field of fertilizer aspect.
Background technology
In recent decades, no matter China in the production level of chemical fertilizer industry, still all obtained bigger progress on the fertilizer practice Study on Theory.But fertilizer at present commonly used is to improving chemical fertilizer utilization ratio, reduce agriculture production cost, increase output, improve quality, reducing labor intensity and agricultural restructuring all is unfavorable.Fertilizer variety is more single in the market, and concentration is low, and proportioning is unreasonable, poorly water-soluble, and utilization rate of fertilizer is low.The a large amount of use caused the soil organisms chain to be destroyed, and nutritive element is unbalance in a large amount of farmlands, the hardening soil, and soil fertility descends, and it is barren all the more that soil becomes, and the dependency of external fertilizer is strengthened day by day.Thereby countries in the world are all in research, exploitation, production and application; Nuisanceless, full nutrition, full validity and the high chemical fertilizer of utilization ratio; For promoting water saving, strengthen environmental protection; And cooperating the application of spraying the drip irrigation integrated technique, the research of strengthening high density, full nutrition, low cost, free of contamination liquid fertilizer is imperative.Liquid fertilizer mainly contains following several kinds at present: organic liquid fertilizer, inorganic liquid fertilizer, biological liquid fertilizer; Organic liquid fertilizer exists effective nutrient content low, and the organic-inorganic proportioning is unreasonable, can not satisfy the drawback of the nutrient demand of crop growth phase.Drawbacks such as biological liquid fertilizer exists the bio-synergistic effect not obvious, and nutrient content is low.Inorganic liquid fertilizer ubiquity nutrient is incomplete, and macroelement and middle trace element can not be effectively compound, dissolves problems such as producing deposition between incomplete or the element.
Summary of the invention
For solving the problem that prior art exists; The invention provides a kind of high-concentration multi-element liquid fertilizer and preparation method thereof; This liquid fertilizer improves utilization rate of fertilizer, reduces the production cost of fertilizer, has improved the solubility rate of nutritive element, has enlarged the scope of using of liquid fertilizer greatly.
The present invention is achieved in that a kind of high-concentration multi-element liquid fertilizer, and this liquid fertilizer includes the trace elements additive, and this liquid fertilizer also includes by following composition by weight and forms, 210 parts of hot water, 325 parts in urea; 75 parts of phosphatase 11s, 225 parts in Repone K, 15 parts in quicklime, 20 parts in Natural manganese dioxide, 6 parts of boraxs; 4 parts in ferrous sulfate, 2.5 parts in zinc sulfate, 2 parts of manganous sulfates, 2 parts in copper sulfate; 1.5 parts of sulfuric acid silicon, 1 part of Sodium orthomolybdate, 6 parts of glucose, 5 parts of sequestrants.
Be chosen as: said sequestrant is EDTMPA.
Be chosen as: said trace elements additive is pressed routine dose and is added.
Be chosen as: said hot water is 80 ℃-90 ℃ purification hot water.
Described high-concentration multi-element liquid fertilizer preparation method, this method comprises the steps:
In No. 1 reaction kettle, glucose is added in the hot water, treat whole dissolvings; Add Repone K; 2-3 minute, add quicklime and Natural manganese dioxide; Add urea after 3-5 minute, fully miscible; Add phosphoric acid again; Reacted 10-15 minute, and added sequestrant, fully miscible, be reaction solution No. 1,
In No. 2 reaction kettles, inject hot water, add zinc sulfate, manganous sulfate, copper sulfate, ferrous sulfate, sulfuric acid silicon, Sodium orthomolybdate successively, the borax reaction adds the trace elements additive after 5 minutes; Stir, react and promptly got No. 2 reaction solution in 20 minutes,
Simultaneously in pump to 3 reaction kettle, temperature remains on 50 ℃-60 ℃ with No. 1 reaction solution and No. 2 reaction solutions; Reacted 15-20 minute, and be cooled to room temperature then; In complete soln pump to 4 settling tank, precipitate 48 hours and both got high-concentration multi-element liquid fertilizer.
The production cost that improves utilization rate of fertilizer, reduction fertilizer is the key that promotes the fertilizer industry development; Against existing technologies, the present invention has overcome the deficiency of existing production technique, has improved the solubility rate of nutritive element; Enlarged the scope of using of liquid fertilizer greatly; Whole process in plant-growth all can be used, this liquid fertilizer has that nutrition is complete, product is stablized, is easy to storage, reasonable ratio, amount of increase in production is big, effect is remarkable, easy to use, be fit to multiple soil and various farm crop and advantage such as use.It mainly acts on, and intensifies the vegetable cell reproduction, composes the physiological function of living, and impels metabolism, replenishes plant nutrition, increases plant enzymes content, the photosynthesis of enhancement of plant.Nutrition is complete, concentration is high, reasonable ratio: promptly contain macroelement, in containing again, trace element, each element proportioning is to adjust by Different Crop nutrient demand characteristic.Do not precipitate: solved the composite precipitation problem of phosphoric acid salt, vitriol and metallic cation, can place for a long time and not precipitate.Pollution-free: this fertilizer solvability is good, cooperates the spray drip irrigation equipment, realizes water and fertilizer coupling, and the fertilizer requirement of fertilizer amount and crop is coincide constantly, and utilization rate of fertilizer is high, and is residual few, can not cause the eutrophication of water body, is free of contamination environment-friendly fertilizer.Promote crop to take root, germinate, tiller, increase flower, increase fruit, setting, full real, raising the output, promote branches of fruit trees to increase, prolong leaf longevity, improve fruit quality, the content of the protein that improves fruit and sugar part etc., enhancing fruit storage tolerance ability.The resistance of enhancing crop can obviously improve farm crop drought resisting, cold-resistant, resistant to lodging and diseases and insect pests resistance.
