Description
Technical Field
The invention relates to the technical field of compound fertilizers, in particular to an organic-inorganic compound fertilizer for crops and a preparation method thereof.
Background
The organic-inorganic compound fertilizer is a compound fertilizer containing both organic matter and a proper amount of chemical fertilizer. The organic materials such as excrement, peat and the like are subjected to harmless and effective treatment through microbial fermentation, and a proper amount of fertilizer, humic acid, amino acid or beneficial microbial bacteria are added to prepare the commercial fertilizer through granulation or direct blending. The organic-inorganic compound fertilizer has the following advantages: (1) the organic matter part of the organic-inorganic compound fertilizer is mainly organic fertilizer, mainly animal and plant residues, and can effectively provide organic nutrient elements for plants through fermented and decomposed organic matters. The crops are equivalent to farmyard manure, but the farmyard manure is not fermented and decomposed generally and contains a large amount of pathogenic bacteria, parasitic bacteria and the like to cause seedling burning. (2) The nitrogen, phosphorus and potassium content is balanced, and meanwhile, a large amount of beneficial bacteria are contained, so that the effects of nitrogen fixation, phosphorus dissolution and potassium dissolution can be achieved, the absorption of nitrogen, phosphorus and potassium is promoted, and the nitrogen, phosphorus and potassium absorption rate is improved. Compared with the method of only fertilizing nitrogen, phosphorus and potassium, the absorption rate can be improved by about 30-50%. (3) The organic-inorganic compound fertilizer is also doped with biological bacteria, various beneficial bacteria can play the roles of effectively fixing nitrogen, dissolving phosphorus and dissolving potassium, and the metabolites of the beneficial bacteria also have nutrients with extremely high nutritional values. (4) Other beneficial elements such as trace elements, multienzyme, polypeptide and the like are added into part of the product, so that the nutrition is more comprehensive, and the nutrient is really free of short plates.
The existing organic-inorganic compound fertilizer is used for the granulation problem, farmers are used to use chemical fertilizers and compound fertilizers for granulation, and the non-granulated fertilizer is not good fertilizer. The national standards also specify granulation and are clearly "spherical" or "columnar". This standard poses three problems.
Firstly, raw material chemical fertilizer is firstly crushed and then mixed with powdery organic fertilizer, and the mixture is granulated by a granulator. If the fertilizer is spherical, the water content of the granulated fertilizer is about 50 percent, and the water content of 50 percent is reduced to 10 percent, the fertilizer needs to be dried at high temperature, so that the organic water-soluble substances in the fertilizer are carbonized and lose the biological effectiveness.
Secondly, the processing cost is high, increase peasant's burden, and granulation is than simple mixing after the mixing, and per ton product increases 150 ~ 200 yuan processing cost.
Thirdly, the spherical granulation uses an adhesive, the columnar granulation uses strong pressure, and the two types of granulation both ensure that fertilizer granules can not disintegrate for a long time in a drought season and a rain-less area, the nutrition of the fertilizer can not be released, and the fertilizer can not be synchronously supplied in the fertilizer requiring stage of crops, so that the crops have poor harvest.
