Description
Technical field
The present invention relates to the technical field of fertilizer additive, relate in particular to a kind of selenium slow-release fertilizer additive and production technique thereof of containing.
Background technology
Along with the minimizing in population increase and arable land, and the raising of people's living standard, require agricultural to improve constantly output and quality product.Fertilizer occupies critical role in agriculture production, in many Yield-increasing Factors, it offers rate is 30%, and China is that chemical fertilizers production is used big country, and its output and usage quantity all occupy first place in the world, but quality product is still waiting further raising.Subject matter is that the utilization ratio of fertilizer is low, fertilizer efficiency period is short, function singleness, in base, the fertilizer efficiency period of nitrogenous fertilizer only has 30-50 days, and general farm crop need be 90-120 days the fertile phase, the fertile phase of the fertilizer phase of fertilizer and the need of crop is inharmonious, can only adopt repeatedly fertilising to solve in agriculture production, this requires far apart with modern agriculture and advanced agrotechnical art popularization; Its utilization ratio only has 30-40%, and another 60-70% enters atmosphere and water body because of volatilization, leaching loss, causes serious waste and environmental pollution.The utilization ratio of phosphate fertilizer is lower, and this season utilization ratio only has 25% left and right, and its major cause is by soil fixing, and crop is difficult to absorb.Be not difficult to find out, extend fertilizer efficiency period very favourable to agriculture production, can reach disposable base manure, release is topdressed, have volume increase, increase income, save fertilizer, saving of labor's comprehensive benefit, meet the requirement that modern agriculture and advanced agrotechnical art are promoted, and increase operation rate not only to agricultural, particularly significant to whole national economy, the main raw material of producing fertilizer is: coal, oil, Sweet natural gas and electric power, mostly be greatly non-renewable resource, and the annual production of fertilizer and usage quantity be all with hundred million tons of calculating, that as seen increases operation rate is significant.Also have environmental contamination reduction, also acquire a special sense, industrial pollution mostly is greatly point-source pollution, relatively control easily, and agricultural pollution is pollution of area source, and there are 1,600,000,000 mu of farmlands in the whole nation, is hard to guard against, pollutes if reduce, and it is to perform meritorious deeds never to be obliterated.
The approach that addresses the above problem, except improving agrotechnique, the research and production sustained-controll-release fertiliser is the important topic of pendulum in face of us.Existing sustained-controll-release fertiliser has three types: the one, and coating, coated, dressing, coating, large the physical such as material; The 2nd, the chemotypes such as urea formaldehyde, oxamide, IBDU; The 3rd, add microorganism and enzymeinhibition agent, be biochemical.Because of factors such as cost, technique and effects, it is less that front two class sustained-controll-release fertilisers are applied, and accounts for 80% sustained-controll-release fertiliser and belong to the biochemical product that adds inhibitor.
Present existing correlation technique and product have: add the long-acting urine of urease inhibitor Resorcinol, the patent No. is: 85109580.1; Add the long-acting ammonium bicarbonate of nitrification inhibitor Dyhard RU 100, the patent No.: 90105012.1; Durable composite fertilizer additive take above-mentioned two kinds of inhibition as the raw material research and production, patent No. 99113382.x, the long-acting complex fertilizer of interpolation inhibitor, the patent No. 98113795,200910248732.1; Various nitrogen fertilizer potentiating agent sustained release drugs, the patent No. 90106467,20061001049.1 etc.
The conversion process of phosphate fertilizer in soil is different from nitrogenous fertilizer, and nitrogenous fertilizer is mainly that decomposition and inversion is fast, and crop has little time to absorb and volatilizees, and leaching loss, phosphate fertilizer are to be easy to be fixed by soil colloid, make crop be difficult to absorb, and utilization ratio is very low.Existing correlation technique has phosphorus element activator for this reason, and the patent No. 200610046170.9 can make the phosphorus minimizing in being manured into soil fixing, is suitably activated by the phosphorus of soil fixing, improves P use efficiency with this.
The developing direction of fertilizer is except slowly-releasing, and is multi-functional in addition, and the appearance of selenium-rich fertilizer agent is arranged for this reason, as the patent No. 01106397.1, improves organism organic selenium and aminoacids content in crop, is the safe and effective benefit selenium of human body optimal path.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of selenium slow-release fertilizer additive and production technique thereof of containing is provided.It has the selenium of containing and two kinds of effects of slowly-releasing, can effectively improve utilization rate of fertilizer, extends fertilizer efficiency period, and has volume increase, increases income, saves the effect of fertilizer.
The present invention realizes that the technical scheme of goal of the invention is as follows:
Contain the selenium slow-release fertilizer additive, it is to be made of following raw materials by weight portion ratio:
Dicyanodiamide: Resorcinol: xylogen: Sodium Selenite: auxiliary material=5～10:20～40:20～30:1～3:17～54.
