(2) urea is soluble in water, regulates pH value to 7.2-8, then adds sucrose monoester, after stirring, obtains liquid B;
(3) 1/3 liquid A is added in liquid B, after stirring, then add remaining liquid A, be heated to 50-54 DEG C, insulation reaction35-40min, is then warming up to 65 DEG C, and insulation 20min, after reaction finishes, is cooled to room temperature, after oven dry, must contain two AsiasThe product of furfuryl group three aldehyde ureas;
(4) will in above-mentioned product, add gibberellin, heteroauxin, methionine and cyclodextrin, after stirring, granulation obtains slowRelease fertilizer.
Further, in step (1), the reagent of described adjusting pH value is that pH value is glycine-NaOH of 9.0-9.4Buffer solution.
Further, in step (2), the solid-liquid ratio of described urea and water is 1g:10ml.
Further, in step (2), it is that pH value is borax-borate buffer of 7.8-8.0 that described adjusting pH value obtains reagentLiquid.
Further, in step (2), the addition of described sucrose monoester accounts for 2% of weight of urea.
Further, in step (3), the mass ratio of described liquid A and liquid B is 1:4.
The concrete constituent content of slow-release fertilizer that the present invention utilizes said method to prepare is: contain two furfurylidene three aldehyde ureasProduct 28-32 part, gibberellin 0.1-0.3 part, heteroauxin 0.08-0.12 part, methionine 0.5-0.7 part, cyclodextrin 50-70 parts.
The slow-release fertilizer that contains two furfurylidene three aldehyde ureas preparing according to above-mentioned preparation method is also in protection of the present inventionWithin scope.
Advantage of the present invention and beneficial effect are:
(1) the present invention utilizes furfural dregs to prepare slow-release fertilizer, wherein contains abundant vitamin, lignin etc., and organic substance is enteredRow comprehensive utilization, turns waste into wealth, and reduces environmental pollution, increases its economic value added;
(2) the slow-release fertilizer fertilizer efficiency that prepared by the present invention is long, and dose is few and number of times is few, improves soil quality, has water conservation effect.
