Abstract
The present invention discloses an additive, a durable compound fertilizer containing said additive and its preparing process. Said additive contains N-fertilizer synergistic agent which containing urease inhibitor (5-15 wt.%) and nitration inhibitor (15-45 wt.%), ammonium ion stabilizer (38-79 wt.%) and rare-earth elements (1-2 wt.%). A durable compound fertilizer is prepared from the compound fertilizer containing N, P, K and trace element (80-95 wt.%) and said additive (5-20 wt.%). Its advantages are longer effective period elongated to 100-360 days, high utilization rate of nitrogen element raised by 5-10%, high crops yield increased by 10-15% and less consumption of fertilizer decreased by 20%.
Description
The present invention relates to a kind of additive that is used for composite fertilizer, contain this additive durable composite fertilizer and production technique thereof.
The compound fertilizer special of producing at present and using mostly is nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and trace element fertilizer and forms, wherein nitrogenous fertilizer is urea, phosphorus ammonium and carbon ammonium, because the fertilizer efficiency period of nitrogenous fertilizer short (40～60), utilization ratio low (35%), so when making base manure with composite fertilizer special, it is under-supply nitrogen generally to occur in the crop growth middle and later periods, in order to satisfy the needed nitrogen nutrition of crop, also needs to append nitrogenous fertilizer in good time.Not only time-consuming, the effort but also extremely unbecoming of topdressing with modern agriculture.
At the problems referred to above, domestic scholars is successively developed the nitrogen fertilizer potentiating agent (patent No.: 9411013210, number of patent application: 98121029.9), long-acting nitrogen fertilizer (the patent No.: 85109580.1, the patent No.: 90105012.1) and long-acting specific composite fertilizer (application number: 96119508.8, application number: 98113795.4).
Nitrogen fertilizer potentiating agent is a kind of auxiliary agent that improves fertilizer effectiveness, divides two kinds of nitrated and urease inhibitorses, and they can improve utilization rate of nitrogen fertilizer effectively and prolong its fertilizer efficiency period, makes agricultural reach volume increase, increases income province fertilizer saving of labor's comprehensive benefit.Using of it is to join by a certain percentage in the nitrogen fertilizer production flow process with nitrogenous fertilizer, produces the long-acting nitrogen fertilizer that contains nitrogen fertilizer potentiating agent, uses for agricultural then.
Long-acting specific composite fertilizer is that nitrogen fertilizer potentiating agent is added in the compound fertilizer production technology by a certain percentage, produces the various long-acting specific composite fertilizer material that contain nitrogen fertilizer potentiating agent.
The production of above-mentioned controlled availability fertilizer and apply agricultural has all been played good effect, making agriculture production reach disposable base manure need not topdress, though can reach volume increase, increase income, economize fertilizer and saving of labor's good result, and welcome by vast farmers.But logical practice in a few years finds that the fertilizer efficiency period of above-mentioned controlled availability fertilizer generally can only extend to 90～120 days, can only be fit to the needs of general farm crop, and for longer can't being suitable for as lawn, nursery stock, sugarcane etc. breeding time.In addition owing to nitrogen fertilizer potentiating agent content unanimity in the long-acting specific composite fertilizer.Be evenly distributed, cause seedling stage (fertilising initial stage) for fertile not enough.
The objective of the invention is, overcome the short deficiency of above-mentioned composite fertilizer fertilizer efficiency period, a kind of be applicable to additive, the durable composite fertilizer that contains additive and production technique thereof Different Crop, fertilizer efficiency period length are provided.
For realizing the object of the invention, take technically: produce the specific additive, utilize this Additive Production durable composite fertilizer.
Additive, its component contains (by weight percentage):
Nitrogen fertilizer potentiating agent, the high sub-stablizer 38～79% of ammonium and rare earth element 1～2%; Its nitrogen fertilizer potentiating agent is made up of urease inhibitors 5～15% and nitrification inhibitor 15～45%.
Said urease inhibitors is: quinhydrones; Nitrification inhibitor is a Dyhard RU 100; Described ammonium ion stablizer is careless carbon, humic acid or zeolite powder; Rare earth element is complex rare-earth or modified RE.
The durable composite fertilizer that contains additive, the component that it contains are (by weight percentage): the composite fertilizer 80～95% by nitrogen, phosphorus, potassium and trace element are formed is characterised in that: also contain additive 5～20% on the basis of its composite fertilizer.
Produce the production technique of durable composite fertilizer, its production craft step is:
At first the aforementioned proportion component is put into that container mixes, stirring and granulation, it is characterized in that: take inhomogeneous mode in stirring, promptly churning time is not more than 10 minutes, then the component that stirs is made particulate state, pack forms product.
The characteristics of durable composite fertilizer of the present invention are: owing to add long-acting additive in the composite fertilizer, can make the fertilizer efficiency period of composite fertilizer extend to 100-360 days, nitrogen utilization efficiency improves 5～10 percentage points.Owing to not only contain nitrogen fertilizer potentiating agent in the long-acting additive, also contain ammonium ion stablizer and rare earth element, the fertilizer efficiency period of nitrogenous fertilizer is further prolonged, can also reach simultaneously and strengthen the plant physiology activity, improve the quality of products and to the resistance of poor environment.The nutritional needs of Different Crop whole growing can be satisfied better, under equal rate of fertilizer application (nutrient contg) condition, crop yield 10～15% can be made; Under condition with equal yield line, can save fertilizer application amount 20%, and can reach disposable base manure, exempt the operation of topdressing, thoroughly solved overlay film, exempt from more with agricultural high-tech such as paddy field aquaculture in an inconvenience difficult problem of topdressing.Make the durable composite fertilizer technology more perfect.
Embodiment to the present invention program describes in further detail:
Embodiment 1
Prepare the additive that is applicable to cotton, the durable composite fertilizer (by weight percentage) that contains additive:
With component quinhydrones content is 8%; Dyhard RU 100 content is 20%; Complex rare-earth 1.5%; Grass carbon 70% mixes, stirring, granulation, forms additive product at last.
With the additive level for preparing is in the 6% adding composite fertilizer, through mixing, stirring, granulation process step, and produces durable composite fertilizer.Its stirring technique is taked inhomogeneous mode, and promptly churning time is 3 minutes.
Embodiment 2
Prepare the additive that is applicable to corn, the durable composite fertilizer (by weight percentage) that contains additive:
