Abstract
This invention discloses a N and P fertilizer slow released permanent agent matched with monoammonium phosphate containing urease inhibitor, nitration inhibitor and with natural zeolite with multiple microelements as the carrier in light of weight ratio 1-3:100 and can be matched with any kind of nitrogenous fertilizers to become permanent nitrogenous fertilizer or various compound special fertilizers.
Description
The fertilizer synergistic agent that the present invention relates to is a kind ofly to contain a small amount of urease inhibitor hydroquinone and nitrification inhibitor Dyhard RU 100 and natural zeolite powder and rare earth to add the farm crop trace elements necessary again be the nitrogen and phosphorus fertilizer slow release long-acting agent that carrier is mixed and forms.
China is a developing large agricultural country, and chemical fertilizer unit's amount of application is more than 2 times of world average level, but chemical fertilizer utilization ratio is low, only is about 30%.(bicarbonate of ammonia 25%, urea 35%, ammonium sulfate 40%.) this numeral is lower than about 10 percentage points of developed country.Therefore, improve utilization rate of nitrogen fertilizer, reducing rate of fertilizer application and reducing environmental pollution is China's important topic anxious to be solved.
Purpose of the present invention aims to provide a kind of nitrogen and phosphorus fertilizer slow release long-acting agent of low-cost high-efficiency benefit.Thereby slow down the chemical fertilizer decomposition rate and prolong fertilizer efficiency period, reduce the chemical fertilizer loss, improve chemical fertilizer utilization ratio.Reach the saving manure resources, reduce environmental pollution, reduce agricultural cost, realize the purpose of high-yield and high-efficiency.
China uses more at present, and nitrogen fertilizer potentiating agent has two kinds: a kind of is to utilize present Chemicals quinhydrones or Dyhard RU 100 by the 3-10% of nitrogenous fertilizer weight, directly mixes with nitrogenous fertilizer (as urea or bicarbonate of ammonia), directly applies the farmland.Another kind method is to utilize existing nitrogen fertilizer production apparatus and process that quinhydrones or Dyhard RU 100 are added respectively, makes long-acting carbamide or long-term efficiency bicarbonate ammonium, and then applies the farmland.
Above-mentioned two kinds of technology are put forward effect to guarantor's nitrogen and have been obtained some effects, but also all exist certain shortcoming and defect part.For example, first method is directly mixed with urea with quinhydrones, because inhibitor and nitrogenous fertilizer part by weight great disparity (are generally 1: 200-300), be again same color, so be difficult to puddle evenly.In recent years quinhydrones price increase in addition, cost is more and more higher.The long-acting nitrogen fertilizer of the interpolation inhibitor that second method is made because inhibitor is relatively-stationary ratio, and can not satisfy the different demands of different soils and Different Crop, also is difficult to bring into play optimum efficiency.
Technical solution of the present invention is as follows:
In the material with urease inhibitor and nitrification inhibitor, adding the natural zeolite powder that advances to contain the farm crop trace elements necessary is carrier.Inhibitor is 1 with the mixed weight ratio of cutting out body: 20-30; The granularity of carrier is 0.05-2mm.
This nitrogen and phosphorus fertilizer slow release long-acting agent compared with prior art has following advantage:
1, because this nitrogen and phosphorus fertilizer slow release long-acting agent carrier is a natural zeolite powder, itself has unique three-dimensional frame shape structure and crystal chemistry character.Huge surface-area is arranged and occupy 50% hole passage of cumulative volume.Self have a large amount of positive and negative charges, can produce very big electrostatic attraction, it is not only to the cation-adsorption in the soil, and the multiple negatively charged ion that soil colloid is difficult for absorption also can adsorb.This is highly beneficial to slowing down chemical fertilizer decomposition rate prolongation fertilizer efficiency period.Therefore, combine with nitrogen phosphorus fertilizer and to use, not only can adsorb the ammonium ion in the nitrogenous fertilizer, slow down ammonium nitrogen and be converted into the speed of response of nitric nitrogen, thereby the prolongation fertilizer efficiency period reduces nitrogen loss, and can also produce adsorption to the phosphate radical in the phosphate fertilizer, slow down phosphorus fixing in soil, improved the utilization ratio of phosphate fertilizer.
2, with quinhydrones, the direct mixed phase ratio of urea, not only save the quinhydrones consumption, make the inhibitor consumption drop to below 1% of nitrogenous fertilizer total amount, also be easier to puddle evenly.Reduce cost 20%.
3, the suitable especially compound fertilizer that adds makes compound fertilizer slow-releaseization, long-actingization.This nitrogen and phosphorus fertilizer slow release long-acting agent can be made into long-acting complex fertilizer or long-acting special fertilizer targetedly according to different soils Different Crop needs, reaches the fertile synergy best effect of joint.
4, this nitrogen and phosphorus fertilizer slow release long-acting agent starting material are easily purchased, and production technique is simple, and are with low cost, and apply in optimum small-sized chemical fertilizer manufacturing enterprise and rural area.
This nitrogen and phosphorus fertilizer slow release long-acting agent cost is low, application is wide, suitable various nitrogenous fertilizer, the phosphate fertilizer of adding; Suitable various soil and crop, pollution-free noresidue.Use this nitrogen and phosphorus fertilizer slow release long-acting agent and nitrogenous fertilizer, phosphate fertilizer and be mixed under the fertile and same equal consumption condition of making of nitrogen manure of slow release long-acting, can make increasing crop yield 8-16%.Under equivalent output condition, can save fertilizer 20-25%.Do the base manure deep placement, can save the recruitment of topdressing.
Narrate technical characterictic of the present invention with example below:
1, gets 2 parts of urease inhibitor hydroquinone, 3 parts of nitrification inhibitor Dyhard RU 100s, 10 parts in zinc sulfate, 10 parts of boraxs, ferrous sulfate 1-2 part, rare earth 1-5 part.All the other fill and add natural zeolite powder to 100 part.Zeolite particle size is 0.05-2mm, and thorough mixing is even, can with the nitrogenous fertilizer that designs in advance, phosphate fertilizer, potash fertilizer by weight 1-3: 100 are mixed into durable composite fertilizer or long-acting special fertilizer.
2, get 3 parts of nitrification inhibitor dihydro-amines, 10 parts in zinc sulfate, 10 parts of boraxs, 1 part in ferrous sulfate, 1 part in sal epsom, rare earth 1-5 part.All the other fill and add fully mixing of natural zeolite powder to 100 part (granularity is the same).Can with bicarbonate of ammonia by weight 5-10: 100 are mixed into polynary bicarbonate of ammonia.
3, get 1 part of urease inhibitor hydroquinone, 2 parts of the two cyanogen ammoniums of nitrification inhibitor, 10 parts in zinc sulfate, 10 parts of boraxs, 1 part in copper sulfate, ammonium molybdate 0.5-1 part, rare earth 1-3 part, can with the nitrogenous fertilizer that designs in advance, monoammonium phosphate, potash fertilizer by weight 1-3: 100 are mixed into soybean long-acting special fertilizer.
The nitrogen and phosphorus fertilizer slow release long-acting agent making method:
Urease inhibitor or nitrification inhibitor are sent into mixing tank after the metering of sieving; Should add trace element in the carrier and rare earth etc., after the crushing screening metering, send into mixing tank, add the natural zeolite powder of capacity then.After the full and uniform mixing, just made and to have made nitrogenous fertilizer, phosphate fertilizer synergy product---nitrogen and phosphorus fertilizer slow release long-acting agent through metering, packing again.
