Abstract
The invention relates to a mixed sustained-and-controlled-release fertilizer and a preparation method thereof. The mixed sustained-and-controlled-release fertilizer is prepared from the raw materials, by weight: 20-40% of an organic fertilizer, 20-30% of sustained-and-controlled-release urea, and 30-60% of a common chemical fertilizer. The organic fertilizer is a granular organic fertilizer with organic matter content higher than 15%. The sustained-and-controlled-release urea is sulfur-coated urea. The common chemical fertilizer is a mixture of 2 or more than 2 selected from granular diammonium phosphate, monoammonium phosphate, potassium chloride, and potassium sulfate. According to the invention, the organic fertilizer, the sustained-and-controlled-release urea, and the common chemical fertilizer are well mixed according to the ratio, such that the fertilizer provided by the invention is adopted. Because a certain amount of the organic fertilizer is doped into the common blended fertilizer, soil hardening degradation is prevented, soil is fertile, and cost is reduced. According to the invention, the sulfur-coated urea is used for completely substituting large-particle urea in the blended fertilizer, such that nutrient loss caused by excessive releasing speed of common urea is prevented, and chemical fertilizer dosage is reduced.
Description
Technical field
The present invention relates to a kind of agricultural fertilizer material, more specifically say a kind of mixing sustained-controll-release fertiliser and preparation method.
Background technology
China is large agricultural country, and agricultural development is the guarantee of national economy and social development.Chemical fertilizer plays great function in agricultural development, as: can increase crop yield, increase soil fertility, compensate the deficiency etc. of ploughing.But the utilization ratio of chemical fertilizer is very low, and utilization rate of nitrogen fertilizer is 25%-40%, and phosphate fertilizer only has about 20%, and potash fertilizer can reach more than 30%, and the chemical fertilizer that runs off can cause environmental pollution.The utilization ratio that applies fertilizers scientifically, conveniently applies fertilizer, improves fertilizer becomes very problems of concern of current peasant.Present used fertilizer or base fertilizer composite fertilizer, the end that the later stage imposes urea, adds and chases after, the disposable input of Bulk Blending Fertilizer (BB fertilizer) done of useful granular urea also, the later stage no longer topdresses, and the peasant cries one to bombard.Add the end of with and to chase after, evaporate in a large number such as the chemical fertilizer that do not rain when topdressing, outflow with water if rainwater is crossed large chemical fertilizer, utilization ratio is extremely low, also waste a large amount of artificial turners, and bombarding disposable input with one must deep fertilizer spraying, is easy to burn root, burns seed.Sandy soil ground, the excessive later stage of hillside fields or rainwater is seriously taken off fertilizer, must topdress, and affects output, the soil degeneration of also can hardening.Because common chemical fertilizer is the leakage especially severe in use, novel sustained and controlled release chemical fertilizer has become the developing direction of world today's chemical fertilizer.
The characteristics of sustained-controll-release fertiliser maximum are to make every effort to nutrient discharge and the Crop synchronization, and fertilizer practice can realize that single fertilization satisfies the crop needs in whole vegetative period, and fertilizer loss is few, and utilization ratio is high.Some sustained-controll-release fertilisers are arranged now on the market, but exist all that some problems are high such as: cost, common urea discharges fast and cause nutrient loss, nutrition is unbalanced, the fertilising process complicated.
Summary of the invention
The objective of the invention is to provide that a kind of cost is low, nutrient is balanced, single fertilization need not topdress that the later stage is not taken off fertile a kind of mixing sustained-controll-release fertiliser and preparation method.
The object of the present invention is achieved like this:
This mixing sustained-controll-release fertiliser feed composition and weight percent are:
Fertilizer 20-40%;
Sustained/controlled release urea 20-30%;
Common chemical fertilizer 30-60%;
This optimum feed stock component and weight percent are:
Fertilizer 30%;
Sustained/controlled release urea 20%;
Common chemical fertilizer 50%;
Described fertilizer is that organic content is greater than 15% granular organic fertilizer;
Described sustained/controlled release urea is sulfur-coated urea;
Described common chemical fertilizer is the mixture more than 2 kinds or 2 kinds in particulate state phosphoric acid two ammoniums, monoammonium phosphate, Repone K, the vitriolate of tartar;
With fertilizer, sustained/controlled release urea, common chemical fertilizer evenly mix in proportion and namely get fertilizer of the present invention;
With the 20kg fertilizer, the 20kg sulfur-coated urea, the 60kg diammonium phosphate namely gets fertilizer of the present invention with even mixing of the mixed fertilizer of Repone K.
Owing to adopt said components and preparation method, this fertilizer had the following advantages:
1) because the present invention adds the degeneration of hardening that a certain amount of fertilizer had both prevented soil in common Bulk Blending Fertilizer, fertile soil has reduced again cost.
2) the present invention all replaces granular urea in the bulk blended fertilizer with sulphur dressing sustained/controlled release urea, has prevented that common urea from discharging too fast and nutrient loss that cause has reduced fertilizer amount.
3) the present invention can take full advantage of organic fertilizer, sustained/controlled release urea, and common fertilizer, mutual coordinative role has guaranteed the nutrient stable market supply of crop from the seedling stage to the ripening stage between the dissimilar nutrients.Increase crop yield, reduced again cost, become possibility so that the present invention is applied to the farmland.
4) the present invention does not contain common granular urea, and any soil (running fertile sandy soil ground of metalling run out, the hillside fields) can single fertilization, and the later stage of need not topdressing is not taken off fertilizer.
Embodiment
This sustained-controll-release fertiliser is comprised of following raw material, and weight percent is:
