Embodiment
The present invention relates to a kind of multifunction long-acting fertilizer, by weight, comprise in 70-85 part N P and K base fertilizer, 10-35 part and measure nutritive element, 2-8 part micronutrient element, 0.05-0.1 part tensio-active agent, 0.05-0.1 part marine alga dextran, 0.05-0.1 part Codiumfragile(sur.) Hariot., 0.1-0.5 part zinc ammonium phosphate, 0.05-0.2 part Korean pine polyphenol.
As one embodiment of the present of invention, described N P and K base fertilizer, is specially: 40-45 part urea, 20-25 part calcium superphosphate, 10-15 part potassium sulfate.
Urea, calcium superphosphate, potassium sulfate mix with rational proportioning, by slow Controlled Release Nitrogen Fertilizer, water suction make moist the little phosphate fertilizer of possibility, good stability potash fertilizer coordinate, obtain the N P and K base fertilizer of increasing soil fertility that utilization ratio is high.
As one embodiment of the present of invention, described middle amount nutritive element, is specially: 5-15 part nanoscale magnesium, 10-20 part nano-scaled electric stone.
Nanoscale magnesium of the present invention is preferably the magnesium oxide of 10-100 nanometer size range, its role is on the one hand for fertilizer of the present invention provides fertiliser containing magnesium; On the other hand as effective inner anti-hard caking agent, its crystal habit can make fertiliser granulates form long, fibrous, pliable and tough crystal, is highly brittle when drying, thus the tendency alleviating caking is had, in the production process of fertilizer, can moisture absorption rate be slowed down, improve water absorbability.The magnesian use of 10-100 nanometer size range, important for invention fertilizer, preferably, as one embodiment of the present of invention, magnesium oxide is obtained by following method: crushed material, after ball mill high speed pulverization, is obtained head product by magnesite after 200-300 order sieves process; By head product warp, 880-900 DEG C of calcining, obtains the magnesium oxide of 10-100 nanometer size range after being cooled to room temperature.
Tourmalinite is the silicate containing boron, and as one embodiment of the present of invention, nano-scaled electric stone of the present invention is preferably the tourmalinite of 10-100 nanometer size range, its role is on the one hand for fertilizer of the present invention provides boron fertilizer, favourable to plant growth; All right emitting far-infrared, the anion releasing of nano-scaled electric stone on the other hand, thus possess the function stimulating plant growth, and the remains of pesticide in soil can be adsorbed, purification crop growth environment.
As one embodiment of the present of invention, described micronutrient element, be specially: the micronutrient element of cupric, cobalt and zinc, the micronutrient element of described cupric, cobalt and zinc obtains through following step: be scattered in the zinc carbonate aqueous solution under cobaltous carbonate ultrasound condition, and the weight ratio of cobaltous carbonate and zinc carbonate is (0.01-0.02): 1; PH adjusting agent regulates pH to be 7; Gained throw out room temperature ageing 24h, absolute ethanol washing after throw out is filtered ,-30 DEG C of lyophilizes, the freezing sample of gained is-45 DEG C, 13 – 20Pa Freeze Drying Equipment dehydrations; By the product after dehydration through 600 DEG C of calcining 2h, obtain Co-doped ZnO nanocrystalline particle; To be scattered in copper sulfate solution under described Co-doped ZnO nanocrystalline particle ultrasound condition, the weight ratio of Co-doped ZnO nanocrystalline particle and copper sulfate be (0.1-0.2): 1; Room temperature vigorous stirring 30min, guarantees Cu
2+be adsorbed on ZnO surface, washing is for several times placed in deionized water and keeps suspended state, 70 DEG C of stirring in water bath heating 5min, ammoniacal liquor adds until produce precipitation, stirring in water bath heating 30min, filtration washing, obtain the micronutrient element of cupric, cobalt and zinc, be wherein based on zinc oxide, wherein, copper absorption is at zinc oxide surface for cobalt doped.Wherein in the zinc carbonate aqueous solution, zinc carbonate and water weight ratio are (10-20): 100, and in copper sulfate solution, copper sulfate and water weight ratio are (10-20): 100.
The micronutrient element of cupric, cobalt and zinc, possesses higher contact surface area/total surface area ratio, to realize maximized surface contact; Can slowly dissolve with releasing nutrients element positively charged ion, the efficiency of conveying nutritive element improves greatly.
Described pH adjusting agent is sodium silicate solution.Adding of pH adjusting agent makes contain a small amount of water glass in final Co-doped ZnO nanocrystalline particle, invalid phosphorus potassium in soil can be converted into available nutrient by it, increase the content of available nitrogen, phosphorus, potassium in soil, absorb for crop, promote plant growth; Water glass can improve anti-wear and the crush strength of fertiliser granulates.
Tensio-active agent of the present invention, be specially: 0.02-0.05 part citric acid and 0.05-0.08 part EDTA, described citric acid and EDTA act on after plane of crystal adsorbed simultaneously, one end of its polar group is towards crystal, and one end of nonpolar group outwardly, define the very thin hydrophobic membrane be coated on plane of crystal, play and prevent from absorbing water and the effect of protection crystal water, thus inhibit dissolving and the recrystallization process of plane of crystal, alleviate or eliminate the anti-caking of material; With the granule crystal of tensio-active agent process, under storage requirement after moisture absorption, moisture is between particle or when particle surface forms liquid film to a certain degree, be adsorbed on surfactant molecule on crystal total some enter solution, thus reduce the surface tension of solution, and the contact angle of liquid film is changed, intergranular capillary attraction power is declined greatly; Because tensio-active agent in liquid film same effect occurs to new crystallite of separating out again, even if form brilliant bridge, also become easy fragmentation, the agglomeration preventing performance of product is improved; In addition, the heavy metal in EDTA activating soil, citric acid and the EDTA simultaneously coordinate bond different from harmful metal ion in soil combine, and form the macromole inner complex that crop not easily absorbs, cause the Available Cu content in soil to decline.
The poly physical efficiency of the amino hexose in marine alga dextran of the present invention is scattered in soil the cation group glucosamine polymer forming positively charged, well can adsorb each bacterioid in soil, fungi, suppress its fissiparity function, and the remains of pesticide that can adsorb in soil, purification crop growth environment.
Codiumfragile(sur.) Hariot. Mineral Element Contents of the present invention enriches, and especially micro-Cu, Fe, Zn content is high.
Zinc ammonium phosphate of the present invention, as slow molten micro-fertilizer, grows required fertilizer for crop provides.
Korean pine polyphenol of the present invention contains a large amount of neighbour two phenolic hydroxyl groups, wherein adjacent two phenolic hydroxyl groups can with chromium metal ion generation complex reaction, thus active adsorption soil harmful metal ion, purification crop growth environment.
Nitrogen of the present invention, phosphorus, potassium element, measure nutritive element in magnesium, boron, and Yi Jitong, cobalt, zinc micronutrient element element, for plant growth provides nutrient; The conbined usage of tensio-active agent citric acid and EDTA, soil sanitation sorbent material marine alga dextran, zinc ammonium phosphate, Codiumfragile(sur.) Hariot. and Korean pine polyphenol, comprehensive nutrition, functional diversities.
