Description
Technical field
The present invention relates to the fertilizer additive technical field, relate in particular to a kind of multifunctional creep Controlled Release Fertilizer synergistic agent and production technique thereof.
Technical background
Along with population increases and the minimizing of ploughing, and the raising of people's living standard, require agricultural constantly to increase output and improve the quality of products.Fertilizer occupies critical role in agriculture production, shared weight is more than 30% in many Yield-increasing Factors.China is chemical fertilizers production and use big country, and its output and usage quantity all occupy first place in the world, but quality product is still waiting further raising, and subject matter is that utilization rate of fertilizer is low, fertilizer efficiency period is short, function singleness.Wherein the fertilizer efficiency period of nitrogenous fertilizer only has 30-50 days, and general crop need be 90-120 days the fertile phase, and the fertile phase of the fertilizer efficiency period of fertilizer and the need of crop is inharmonious, and can only taking in the agriculture production repeatedly applies fertilizer solves, and the operation of topdressing is wasted time and energy, and is extremely unbecoming with modern agriculture.Nitrogen utilization efficiency only has 30-40%, and 60-70% is by volatilization in addition, and leaching loss enters atmosphere and water body, causes serious waste and environmental pollution; The utilization ratio of phosphate fertilizer is lower, and this season utilization ratio only has about 25%.Be not difficult to find out, prolong fertilizer efficiency period favourable to agricultural, can reach single fertilization, have volume increase, increase income, save fertilizer, saving of labor's comprehensive benefit; And increase operation rate not only to agricultural, particularly significant to whole national economy, have and economize on resources eco-friendly social benefit and ecological benefits.
The approach that addresses the above problem is except improving agrotechnique, and research and production long-acting slow-release fertilizer is one and gets twice the result with half the effort effective measure.Existing long-acting slow-release fertilizer has three types: 1, physical: various dressings, coating, coated, large-particle long-acting slow release fertilizer; 2, chemotype: urea formaldehyde, isobutyl be two ureas, oxamide etc. again; 3, biochemical: the stable fertilizer that adds various microorganisms and biological enzyme inhibitor.Because of factors such as cost, techniques, front two class slow release fertilizers are applied less, and it is stable fertilizer that 80% long-acting slow-release fertilizer all belongs to the biochemical long-acting slow-release fertilizer that adds inhibitor.
Existing correlation technique and product have in the market:
1, the patent No.: 851095801, denomination of invention is: the long-acting carbamide that adds Resorcinol; This patent discloses a kind of long-acting urea fertilizer that contains urease inhibitor and urea or urea derivative, it is characterized by in urea or urea derivative the Resorcinol that adds (calculating by weight percentage) 0.05-0.30. the present invention also provides the production technique of the long-acting urea fertilizer that a kind of manufacturing contains Resorcinol and has produced specific equipment, this mainly is before the carbamide granulation operation, increase the mixed processes of one Resorcinol liquid and urine, say on the slave unit. only need to set up two solution mixers, a Resorcinol storage tank and two liquid urine. long-acting urea fertilizer provided by the present invention is comparable common urea with increased yield 6-20%. in field experiment
2, the patent No.: 901050121, denomination of invention is: long-acting ammonium bicarbonate and preparation method thereof: this patent discloses a kind of long-acting chemical fertilizer ammonium bicarbonate and preparation method thereof, it is characterized in that it is by a small amount of latent curing agent and the nitrate reductase inhibitor of bicarbonate of ammonia interpolation, the eutectic or the mixture that form, its preparation process are to utilize the technique of producing bicarbonate of ammonia to be improved to form.It is 25-30% that this fertilizer can improve nitrogen utilization efficiency, prolongs fertilizer efficiency period 40-60 days, reduces rate of fertilizer application 20-30%, and fertilizing method can change by topdressing the front base manure of sowing into, can save the operation of topdressing.And have obvious effect of increasing production, amount of increase in production is more than 10%
Durable composite fertilizer additive take above-mentioned two kinds of inhibitor as raw material production.
3, the patent No.: 99113382X, denomination of invention is: long-acting complex fertilizer additive; This patent discloses a kind of long-acting complex fertilizer additive.Form preparation by quinhydrones, Dyhard RU 100, complex rare-earth and zeolite powder, its weight ratio is 2 ~ 8 quinhydrones; 3 ~ 25 Dyhard RU 100s; 0.1 ~ 0.8 complex rare-earth, 70 ~ 95 zeolite powders.
The behavior of phosphate fertilizer in soil is different from nitrogenous fertilizer with process, and nitrogenous fertilizer mainly is that decomposition and inversion is fast, and crop has little time to absorb and volatilizees leaching loss; Phosphate fertilizer is to be easy to be fixed by soil colloid, make crop be difficult to absorb, and utilization ratio is very low.There is phosphorus element activator to occur for this reason, such as the patent No.: 2006100461709, denomination of invention is:.The phosphate fertilizer that is manured into soil is reduced fixing, and can make the suitably activation of phosphorus element that before had been fixed in the soil, crop is absorbed, to improve P use efficiency.
The developing direction of fertilizer is except long-acting slow-release, multi-functional also is an importance, there is Water preserving nitrogenous fertilizer synergist to come out for this reason, such as the patent No.: 031342000, denomination of invention is: Water preserving nitrogenous fertilizer synergist and preparation method thereof, the disclosed Water preserving nitrogenous fertilizer synergist of this patent is made of by weight following raw material: water-holding agent: nitrogen fertilizer potentiating agent: carrier=0.5-2:0.5-2:4-6.The preparation method is: choose according to the above ratio water-holding agent, nitrogen fertilizer potentiating agent and carrier, with carrier drying to moisture content less than 20%, be crushed to 30 orders-80 order; Above three kinds of raw materials are dropped in the stirrer, fully stir, mix, be distributed into bag, and get final product.This product also has water conservation drought resisting function except having nitrogenous fertilizer synergy.
From the introduction of the said products or patent, existing technology all still lacks a kind of with the multi-functional product that combines with long-acting slow-release, especially lacks to reach long-acting slow-release, has again the multifunctional creep Controlled Release Fertilizer synergistic agent of water conservation drought resistance function; But how to guarantee that fertilizer is unlikely to that leaching loss enters atmosphere and water body is current utmost point problems to be solved, therefore necessary this first and second is improved.
