Abstract
A long-effective compound fertilizer with nitrogen, phosphorus, potassium, silicon and calcium and its production are disclosed. The procedure is carried out by removing carbodithioic block from yellow phosphorus slag, drying grinding into powder to obtain silicon element, calcium element and phosphorus element, crushing quality phosphate, drying, grinding, adding into phosphorus element, crushing nitrogen element, adding into potassium fertilizer, mixing with calcium silicate and phosphorus powders, agitating, diluting, granulating, drying and packing. It has non-volatility, long fertilizer effect, more yield and better quality. It can be used for grain, vegetables and fruits.
Description
Technical field: the present invention relates to composite fertilizer, particularly a kind of nitrogen phosphorus potassium silicon five elements durable composite fertilizer and preparation method thereof.
Background technology: N-P-K mixed fertilizer of the prior art is that the China and even the world are traditional, general compound manure.Because the nitrogen element is at the crop growth initial stage, brought into play fertilizer efficiency too early too quickly, the performance fertilizer efficiency action period is short, often, just to remake once and topdress, otherwise just not reach the desired result of high yield in plant-growth mid-term and later stage, so, the cost of grain-production has raise, and the level of the productive forces of objectivized labour has also increased, and is unfavorable for peasant's fundamental interests.
Summary of the invention: the object of the present invention is to provide a kind of nitrogen phosphorus potassium silicon five elements durable composite fertilizer and preparation method thereof, utilize this durable composite fertilizer can reach the raising fertilizer nutrient, improve the soil, improve the purpose of grass achievement quality and increase output.
Formation of the present invention: it is elementary composition by the following weight proportioning, and be measure unit with 50kg: nitrogen element 13.5kg, phosphoric 10kg, potassium element 5kg, element silicon and calcium constituent amount to 21.5kg.
The preparation method of nitrogen phosphorus potassium silicon five elements durable composite fertilizer is:
One, richness is produced the waste of industrial yellow phosphorus, claim industrial refuse yellow phosphorus furnace slag sieve to remove waste piece again, oven dry, with 180 diameter ball mills or 2.2 * 4.4 that air swept mill is levigate, reach the percent of pass of pulverulence 85~90%, obtain 32.56% W (SiO2) element silicon, the calcium constituent of W (CdO) 36.37%, and W (P
2O
5) 11.87% phosphoric;
Two, with the fragmentation of high-quality phosphorus ore, oven dry, porphyrize is to 85 order to 90 orders, adds composite fertilizer's five elements into and smelts the carbamate additives for low phosphorus that yellow phosphorus remains between the silico-calcium element and mixes as the ground phosphate rock element, the increase index of filling a prescription;
Three, the nitrogen element is pulverized, potash fertilizer is advanced in fusion, with silicon calcium powder, ground phosphate rock (ground phosphate rock must by conversion) is mixed together stirring, carries out granulation after the dilution, is delivered in the drying plant with rotary conveyor after the granulation and dries, the 50kg that packs into, 25kg or 10kg, the plastic packing article of 5kg is packed.
Compared with the prior art, element silicon of the present invention and calcium constituent are considered to the 4th and the fifth-largest improving the soil after nitrogen phosphorus potassium, improve grass achievement quality, improve grain matrix because of, sterilization, promote soil to the NPK fertilizers nutrient absorbing, alleviate the novel substance element that heavy metal such as ferromanganese damages soil.
Experiment showed, that after deliberation and at present the silico-calcium element has significant promoter action to growing of farm crop such as water paddy and wheat class, sugarcanes, especially paddy rice belongs to the typical silico-calcium crop that needs.
The silico-calcium element plays a role unlike the nitrogen element soon, easily runs off.It can make the nitrogen element form curing, conditional, bring into play the effect that fleshes up, reach balance fertilizing, progressive effect for the crop absorption, studies have shown that, use calcium silicate fertilizer following effect: A to be arranged, increase output, on average increase production 13% as paddy rice, wheat increase yield 10%, cotton, soybean, sugarcane, peanut, jowar increase production 8% to 15% respectively; B, applied range expand on more than ten kind of staple crops such as peanut, lotus rhizome, apple, cotton, flowers, tealeaves from paddy rice, wheat, soybean, vegetables, sugarcane, corn, have all obtained gratifying effect; C, improve quality of agricultural product, the normal growth of farm crop is grown the nutrient that not only needs nitrogen phosphorus potassium, and needs to form the various nutrient elements of output, and exists the equilibrated ratio between the various nutritive element.Soil and farm crop are replenished certain element silicon and calcium constituent, help grain and fruit and vegetable and be rich in middle trace element, people and animals have eaten just real safe nutrition.
On the total nutrient operative norm of the fertile element of n-p-k three elements compound, increase element silicon 12%, calcium constituent 16%, make five elements composite fertilizer on the basis of total nutrient 25%, increase by 28 nutritive elements again, make five elements composite fertilizer on 25 nutrients of traditional three element compound fertilizer, be increased to 53 above nutrients.Promote soil and crop and be badly in need of additional nutritive element, improve the nutrient standard and the interior letter of compound manure.Make compound manure after increasing element silicon and calcium constituent, not only soil, farm crop are had the effect that improves quality, and have the function that sick worm endangers the crops in virus killing, sterilization, the inhibition edaphophyte.Promote photosynthesis, strengthen that crop is resistant to lodging, drought-resistant, disease and insect resistance, anti-continuous cropping ability, improve product production, improve fruit quality, long-acting.
Rubbish is smelted in industry because the silico-calcium element has drawn from, and turns waste into wealth, and cost is low, and is effective, makes behind the particle easy to use.
Embodiment: with yellow phosphorus furnace slag sieve remove waste piece, oven dry, with the ball mill of 180 diameters or 2.2 * 4.4 that air swept mill is levigate, reach pulverulence 85~90% percent of pass, obtain the element silicon 32.56% of elementary formula material, calcium constituent 36.37%, phosphoric 11.87%.Be measure unit according to 50 kilograms then, get 13.5 kilograms of nitrogen elements, 10 kilograms of phosphoric, 5 kilograms of potassium elements, the silico-calcium element mixes stirring for 21.5 kilograms, dilution back granulation, oven dry, packing.
