A kind of sugar alcohol urea organic foliar fertilizerTechnical field
The present invention relates to the preparation of a kind of sugar alcohol urea organic foliar fertilizer, be applied to agricultural and forestry production field, especially high added value industrial crops.
Background technology
Along with the raising of the reach of science and technology, agricultural science and technology have also been obtained fast development, and traditional agriculture is replaced by intensive big production just gradually.Intensive big production is economic and environment-friendly big production, it is desirable to provide efficient nutrient substance in the easiest mode for crop.Therefore sprinkling irrigation, drip irrigation are replacing traditional artificially applying fertilizer mode.
Fertilizer is proposed new requirement by the development of drip irrigation and spray irrigation, and the fertilizer being suitable for drip irrigation and sprinkling irrigation must have good water solublity, it is easy to is absorbed by plant, and preferably acid and be unlikely to block irrigation equipment because of hard water fouling.
Sugar alcohol is a kind of small molecule polyol, it is widely present in plant phloem juice, being various nutrient elements carrier, carry mineral nutrient fast transportation in plant phloem, phloem is the main path that the nutrient substance such as mineral nutrient, sugar, carbohydrate enter product organ;The effects such as sugar alcohol also has reduction surface tension of liquid, enhancing liquid exhibition is puted forth effort, hydrotropy, dispersion, suspension.
Summary of the invention
The present invention provides a kind of sugar alcohol urea organic foliar fertilizer, can effectively solve the problems referred to above.
A kind of sugar alcohol urea organic foliar fertilizer, its preparation method is as follows: take phosphoric acid 80 ~ 100 parts, heat after 60 ~ 90 DEG C, add 80 ~ 100 parts of carbamide, under stirring, continue heating and thermal insulation reaction 20 ~ 120min, then sugar alcohol 3 ~ 8 parts, potassium amino acid 5 ~ 10 parts, allantoin 0.1 ~ 1 part, kanamycin 0.5 ~ 1 part, polyoxyethylene 20 sorbitan monolaurate 0.5 ~ 2 part, surface finishing agent 0.1 ~ 0.5 part it are sequentially added into, it is sufficiently stirred for insulation reaction 30 ~ 60min after mix homogeneously, it is subsequently cooled to 30 ~ 45 DEG C, introduce crystal seed, crystallization, be drying to obtain product.
Besides urea, other solid materials pulverized 200 mesh sieves before addition so that solid material is prone to mixing, dissolved.
Product is light yellow to comprehensive color crystal, has good protection against the tide, caking performance.
Product has good water solublity, and aqueous solution is acid, can effectively prevent generating or removing the incrustation scale generated of incrustation scale, irrigation equipment has good protective effect;Meanwhile, the mineral in soil can be dissolved so that multiple medium trace element is converted into ionic state, it is easy to the absorption of crop.
Product water solution can spread in blade face well, it is easy to utilization absorbed by crops.Suitable in the full growth cycle of crop, crop root growth can be promoted well, strengthen plant stress-resistance ability, improve the yield and quality of agricultural product.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be further described.
Embodiment 1
Take phosphatase 11 00 part, heat after 80 DEG C, add 100 parts of carbamide, under stirring, continue heating and thermal insulation reaction 40min, then maltotetraose alcohol 3 parts, composite potassium amino acid 10 parts, allantoin 1 part, kanamycin 0.8 part, polyoxyethylene 20 sorbitan monolaurate 2 parts, surface finishing agent 0.5 part it are sequentially added into, it is sufficiently stirred for insulation reaction 50min after mix homogeneously, is subsequently cooled to 30 DEG C, introduce urea phosphate crystal seed, crystallization, fully dries and had both obtained product.
Embodiment 2
Take phosphatase 79 0 part, heat after 85 DEG C, add 95 parts of carbamide, under stirring, continue heating and thermal insulation reaction 20min, then it is sequentially added into breast pears sugar 5 parts, composite potassium amino acid 10 parts, allantoin 1 part, kanamycin 1 part, polyoxyethylene 20 sorbitan monolaurate 2 parts, surface finishing agent 0.5 part, fully stirs
Mix insulation reaction 60min after mix homogeneously, be subsequently cooled to 40 DEG C, introduce urea phosphate crystal seed, crystallization, dry both product.
Embodiment 3
Take phosphoric acid 80 parts, heat after 85 DEG C, add 80 parts of carbamide, under stirring, continue heating and thermal insulation reaction 20min, then sweet sugar alcohol 5 parts, composite potassium amino acid 10 parts, allantoin 1 part, kanamycin 1 part, polyoxyethylene 20 sorbitan monolaurate 2 parts, surface finishing agent 0.5 part it are sequentially added into, it is sufficiently stirred for insulation reaction 60min after mix homogeneously, is subsequently cooled to 40 DEG C, introduce urea phosphate crystal seed, crystallization, dries and both obtains product.
The present invention is not limited only to the above part, and other technical methods realizing the object of the invention in a similar fashion also fall within scope of patent protection of the present invention.
