Abstract
The invention discloses a slow release ammonium carbonate fertilizer which comprises ammonium carbonate and attapulgite, and is characterized in that the ammonium carbonate is arranged in the micro-nano apertures of the attapulgite. The slow release ammonium carbonate fertilizer is prepared according to the preparation method which comprises the following steps: resolving a fertilizer containing ammonium carbonate with water, spraying the resolved fertilizer on the attapulgite, and carrying out stirring for mixing, pelletization, spraying and drying to obtain the slow release ammonium carbonate fertilizer. Compared with the prior art, the slow release ammonium carbonate fertilizer can reduce nitrogen loss by 65 to 80 %; no auxiliary slow release or controlled release technology, such as the oil coating technology, is adopted.
Description
Technical field
The present invention relates to a kind of slowly-releasing volatile salt fertilizer and preparation method thereof.
Background technology
Nitrogen is the requisite nutritive element of plant-growth, and loss of nitrogenous fertilizer need to solve a problem when to be nitrogen manure use always, existingly generally nitrogenous fertilizer is mixed to the problem to reaching control loss of nitrogenous fertilizer with sustained release dosage or controlled release agent.
Attapulgite/stone is a kind of mineral with micro-nano duct; there are reports mixes the fertilizer such as attapulgite/stone and nitrogenous fertilizer to prepare and has the fertilizer that slowly-releasing or control are lost; but this class fertilizer substantially just mixes attapulgite/stone granulate and nitrogenous fertilizer particle to obtain; because nitrogenous fertilizer particle has macro-size (being generally grade); cannot enter in the micro-nano duct of attapulgite/stone at all; therefore; existingly utilize the slowly-releasing of attapulgite/stone to nitrogenous fertilizer or the control fruit of losing efficacy very limited, still need to be aided with other slowly-releasing or control mistake technology.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, and a kind of slowly-releasing volatile salt fertilizer and preparation method thereof is provided.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of slowly-releasing volatile salt fertilizer, comprises volatile salt and attapulgite, and its feature is, described volatile salt is filled in the micro-nano duct of attapulgite.
The preparation method of above-mentioned slowly-releasing volatile salt fertilizer, by the fertilizer water dissolution that comprises volatile salt, then is sprayed on attapulgite, is uniformly mixed, and granulation, spraying is dry, obtains slowly-releasing volatile salt fertilizer.
Because attapulgite is a kind of mineral of high-specific surface area, there is abundant micro-nano duct, therefore, the present invention is unlike the prior art, first by fertilizer water dissolution, after fully mixing with attapulgite again, pass through wicking action, the aqueous solution of fertilizer can be adsorbed the micro-nano duct that enters attapulgite completely, after spraying is dry, water in micro-nano duct is evaporated, and fertilizer is retained, thereby realize fertilizer, is filled in the object (rather than outside attapulgite particle surface) in the micro-nano duct of attapulgite.The strong adsorptivity in micro-nano duct; can make Nitrogen element reach the effect of slow release, only by attapulgite particle and volatile salt particle mixed phase ratio, nitrogen loss can reduce 65%～80% with tradition; and without adopting other auxiliary slowly-releasing or control mistake technology, as coated oil.
Embodiment
Below in conjunction with the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
embodiment 1
A kind of slowly-releasing volatile salt fertilizer, comprises volatile salt and attapulgite, and wherein, volatile salt is filled in the micro-nano duct of attapulgite.Preparation process is as follows:
First, by 100kg volatile salt 150kg water dissolution, be made into fertilizer solution, then fertilizer solution is sprayed to attapulgite, and (particle diameter 10～50 μ are m) upper, are uniformly mixed, until that hand is pinched is agglomerating, but granulation, spraying is dry, obtains slowly-releasing volatile salt fertilizer.
embodiment 2
Be different from embodiment 1, by 100kg volatile salt and 10kg Repone K 100kg water dissolution.
Slowly-releasing volatile salt fertilizer of the present invention directly mixes use with other potash fertilizer, phosphate fertilizer particle.
Finally it should be noted that: the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
Claims (2)
1. a slowly-releasing volatile salt fertilizer, comprises volatile salt and attapulgite, it is characterized in that, described volatile salt is filled in the micro-nano duct of attapulgite.
2. claim 1 is stated the preparation method of slowly-releasing volatile salt fertilizer, it is characterized in that, by the fertilizer water dissolution that comprises volatile salt, then is sprayed on attapulgite, be uniformly mixed, and granulation, spraying is dry, obtains slowly-releasing volatile salt fertilizer.
