Description
Technical field
The present invention relates to a kind of chemical fertilizer.
Background technology
China is fertilizer consumption big country, and the usage quantity of chemical fertilizer occupies first place in the world, because a large amount of uses of chemical fertilizer, particularly science is not used, blindly used, and causes many problems.The picture environmental pollution, agriculture input cost continues to increase the weight of, and Fertilizer application is single, and fertilizer lasting period weak point does not satisfy the growth demand of farm crop.Cause a lot of defectives, affected the formation of farm output.
Use at the agricultural planting apply fertilizer at present and generally use nitrogen phosphorus potassium three large major elements, but the effective rate of utilization of chemical fertilizer is the important factor of overriding concern, N fertilizer utilization rate only is 25%-40%, the utilization ratio of phosphate fertilizer only has about 20%, potassium utilization rate can reach about 30%, on agricultural planting, utilization rate of fertilizer generally is lower than above-mentioned each level, all be to lose by all means about annual to fertilize half, therefore the chemical fertilizer loss is a quite serious problem, the chemical fertilizer of loss part also continues to soil, environment has produced bad consequence, has caused soil compaction, water pollution, the problem such as pollution of agricultural products and Greenhouse effect.Make agriculture input cost continue to increase the weight of, economic benefit is more and more lower.
See the market status, nowadays the bulk blended fertilizer kind is a lot of on the market, and item are numerous and diverse, and also exist certain defect: 1. scientific and technological content is low.Most Bulk Blending Fertilizer all are to pursue simple economic benefit, utilizing exactly common urea to do the nitrogenous fertilizer raw material, and monoammonium phosphate, diammonium phosphate, calcium superphosphate etc. are as the phosphate fertilizer raw material,, simply puddle and form as the potash fertilizer raw material with vitriolate of tartar or Repone K.This two ammoniums, urea, potash fertilizer with peasant oneself purchase mixes to use and does not have much differences in the planting site in fact, is difficult to volume increase and lays good basis, more is difficult to reach the raising fertilizer efficiency, the volume increase extra earning.2. the nutrient of fertilizer is single, lacks the required various nutritive elements of crop, replenishes various middle trace elements if the peasant rethinks, and has increased again agriculture input cost, even like this, the various elements of rear interpolation also are difficult to accomplish reasonable supplement.
Therefore improve chemical fertilizer utilization ratio, alleviating fertilizer pollution, to develop sustainable high-efficiency agriculture be China's problem demanding prompt solution, in recent years country successively put into effect multinomial for " develop agriculture through science and technology, energy-saving and emission-reduction " wait pointed support encouragement policies, to promote the fast development of agricultural, terms of settlement is also being sought by variety of way by relevant department.
Summary of the invention
Short in order to solve the existing fertilizer efficiency phase, improve the utilization ratio of fertilizer in plantation, it is residual to reduce fertilizer efficiency, alleviate environmental pollution, save labour cost, strengthen the drought-resistant ability of farm crop, the invention provides a kind of efficient bulk blended fertilizer, using urea, two ammoniums, potash fertilizer macroelement fertilizer basis to add agricultural water-holding agent polymer substance (pulvis shape), middle trace element (pulvis state), with these two kinds of combinations of substances together, take urea as carrier, make up with cumulative net height molecular substance again and develop.
Bulk blended fertilizer of the present invention be take cumulative net urea as the nitrogenous fertilizer raw material, diammonium phosphate adds the compound manure that water-holding agent and middle trace element mix on as phosphate fertilizer raw material, Repone K as the basis of potash fertilizer raw material, adds trace element among 0.25～0.5kg water-holding agent and the 0. 01～0.5kg in every 100kg compound manure.
The present invention has made breakthrough innovation by comparing with like product in formula for a product, at first uses cumulative net urea as carrier at the nitrogenous fertilizer raw material, advantage is in common nitrogenous fertilizer, and it can control nutrient loss, cumulative synergy, reduce the nutrient volatilization, strengthen crop resistance.The mechanism of action is that the cumulative net is the high molecular material of a kind of active bio, main component derives from ocean shell biological slime, this material has well and circularizes, can be along with formation net water structure is opened rapidly in the dissolving of fertilizer in soil, since its not only with a large amount of negative charges also with a large amount of positive charges, can be with the macroelement in the soil, near the fine full nutrient pool of the formation of crop root that is adsorbed on of middle trace element, reduce the fertilizer decomposition rate, prolong fertilizer efficiency, and can reduce nitrogen, fixing of the leaching loss of potash fertilizer and phosphate fertilizer increased operation rate.After various nutrients were adsorbed on around the root system, when crop needed certain nutrient, nutrient can break away from root system again and rise in crop stem and the blade, thereby realized promoting the whole process of plant growth.Therefore can make N fertilizer utilization rate improve 60%-80%, can reduce 10%-15% in the required rate of fertilizer application of the same quantity farm crop of production, improve the 10%-12% percentage point, improve fertilizer efficiency about 20%.
The cumulative net urea that this product uses is available from Henan XInlianxin Fertiliser Limited Company.
Secondly, in fertilizer, added agricultural water-holding agent composition thing, it is a kind of organic high molecular polymer of unique tridimensional network, or watering rainwater in soil pours water absorbs rapidly and keeps, become solid water and do not flow and do not ooze mistake, keep for a long time local constant humidity, slowly discharge for plant utilization during day drought, the distinctive suction of this material, water storage, water retention property have now been saved a large amount of irrigation water and pouring maintenance labour for society.
The agricultural water-holding agent that uses in this product is produced by Yingde City peace letter water conservation company limited, and its main component is vinylformic acid 55%, sodium hydroxide 30%, acrylamide 15%.Because not all water-holding agent can both be applied in the agriculture production, particularly mix with fertilizer.The water-holding agent product that uses this producer is can directly mix with urea because of it.But water-holding agent also has a common problem, exactly can not be directly and the part chemical fertilizer mix use, because Na (sodium) ion, K(potassium) ion, Cl(chlorine) ion, Ca(calcium) ion and phosphate fertilizer has antagonistic action to water-holding agent, can cause water-holding agent suction multiple sharply to descend, even lose effect.So according to this characteristic, water-holding agent is joined in the urea, in order to reach maximum effect.
Its principle performance:
1. water absorbing and retaining properties: its moisture holding capacity is 13-14kg/cm
2, the water that keeps does not flow and does not ooze mistake, and anti-extraneous physical pressure is strong, can not squeezed out by general physical method; And the suction force of general farm crop root system is 16-17kg/cm
2So, can be absorbed easily by root system of plant.
2. the water reversibility is released in suction: absorb when ambient water is many, discharge when water is few, so absorb water, release the water iterative cycles, and be difficult for by the microbial destruction in the environment, can keep for a long time 3-D solid structure, thereby supply water to plant for a long time.
3. inhale fertile, nutrient preserving capability: a lot of fertilizer elements are because decomposition and the rainwash of sunlight, have little time just to have been slatterned by plant absorbing, the urea that the adsorbable deadweight of this agent is about 100 times, be fixed in the soil and slowly and discharge, can greatly reduce the loss of nutrient, effectively save fertile 20-40%, and fertilizer efficiency period is prolonged.
4. the improvement soil of security: dwindle after discharging because expanding after the water-holding agent suction, soil forms a vesicular structure, and is soft ventilative, both guaranteed the plant demand, can increase again the retention ability of permeability and the sandy soil of clay, pH value is neutral, does not have undesirable substance in the moisture that discharges, and is nontoxic to environment and plant, do not run off with rainwater, natural degradation for many years is reduced to ammonium nitrogen, water and a small amount of potassium ion, effectively improves soil.
Again, in bulk blended fertilizer, added middle micro-pulvis (zinc, silicon, molybdenum, element sulphur, available nitrogen ammonium sulfate pulvis etc.).
In recent years owing to lack technology awareness, people only pay attention to major element (nitrogen phosphorus potassium) in producing, using to cause the middle trace element deficiency in the soil be day by day serious, and soil has lost gentle state, and agriculture production has been caused larger impact.If allow merely peasant's centering trace element understanding get on, and know its importance, time is too very long, so the invention provides easy, the most feasible, the most scientific and technological a kind of way, add trace element in these in fertilizer, the demand that satisfies crop that can balance makes crop any middle trace element and affect, suppress to grow for want of not in growth, cause the underproduction and quality to descend, serious even total crop failure.The high yield of farm crop only can not accomplished with simple n-p-k element thus, also need a large amount of middle trace elements that plant is replenished, promote photosynthesis and aerobic to transform, only have nitrogen phosphorus potassium and middle trace element to complement each other, balance fertilizing satisfies the plant-growth needs, give enough nutrient supply, the good harvest of could getting bumper crops.
1. zinc is with Zn
2+Form absorb, in nitrogen metabolism, zinc can well change the ratio of organonitrogen and inorganic nitrogen, improves greatly drought-resistant anti-low temperature ability, promote the branches and leaves healthy growth, zinc participates in chlorophyllous synthetic, prevents chlorophyllous degraded and forms carbohydrate, and zinc mainly participates in the synthetic of growth hormone, it is the activator of enzyme, the activity that strengthens enzyme improves rate of photosynthisis, and the hydration of catalyzed carbon hydrate promotes to transform.
2. the effect of silicon in agricultural is if silicon is when lacking a little less than stem of plant and the bar growth, and easily lodging and corroded by germ lacks silicon in growth and cause mature spike number to reduce early stage, and growth later stage spikelet number reduces, and zinc has obvious production-increasing function to cereal crop
3. when sulphur lacked, plant growth was subject to serious obstruction, and plant is short and small thin and weak, and blade moves back green or yellow, and stem is thin, and is stiff, and the branch of tillering is few.Sulphur can improve protein content, can improve the quality of crop simultaneously, and can strengthen resisting cold and the drought-resistant ability of crop.
4. the physiological function outstanding behaviours of molybdenum is aspect nitrogen metabolism, and the nitrate reductase of higher plant and biological nitrogen fixation nitrogenase all are the albumen that contains molybdenum, and the molydbenum fertilizer abundance can greatly improve nitrogen fixing capacity and improve protein content.Crop lack molybdenum jointly to show as plant short and small, growth is suppressed, leaf chlorosis is withered so that downright bad.Because pulse family so easily occur to lack the molybdenum phenomenon, shows the root nodule dysplasia to the specific demand of molybdenum, knurl is little and lack, a little less than the nitrogen fixing capacity or can not fixed nitrogen.
Bulk blended fertilizer of the present invention has obtained certain economic gain at proportion of crop planting, has brought strong help for the peasant increases production extra earning.Take paddy rice as example; 72 kilograms of mu volume increase by 2.7 yuan of/kilogram calculating of paddy rice procurement price in 2012, are increased income 194 yuan for every mu.Take soybean as example; 18 kilograms of mu volume increase by 5.1 yuan/kilogram of soybean market valencys in 2012, are increased income 92 yuan for every mu.Take corn as example, 96 kilograms of mu volume increase, by 1.48 yuan of/kilogram calculating of corn procurement price in 2012, mu is increased income 142 yuan.Step of net return rising that this can illustrate the peasant improves about net return 20-30%.Draw to draw a conclusion according to field contrast use: bulk blended fertilizer and conventional fertilizer are compared the corn yield increasing amplitude at 11%-12%, the amount of increase in production 9%-10% of soybean, and the amount of increase in production of paddy rice is more than 8%.This can use this technological achievement widely in agriculture production.
