Example Embodiment

[0012] The present invention is implemented by the following methods:

[0013] A nano-composite fertilizer is characterized in that: it is composed of the raw materials of the following components by weight: 5-20% of urea, 2-5% of monoammonium phosphate, 4-5% of potassium sulfate, 4-6% of potassium dihydrogen phosphate %, 10-15% of nano-ferrous sulfate with a particle diameter of 15nm, 10-15% of nano-carbon with a particle diameter of 10-20nm, 10-15% of humic acid, 5-7% of lignin, 3-5% of BA, water 5-10%, chitosan 1-5%, borax 3-7%, zinc chloride 0.5-1%, sodium molybdate 0.05-0.3%, manganese sulfate 0.05-0.1%, sodium dodecylbenzenesulfonate 0.05-0.3%, ferrous sulfate 0.8-2%, magnesium sulfate 0.03-0.8%, copper sulfate 0.01-0.05%, dimethyl sulfoxide 0.2-2%; plant fiber 2-10%, livestock manure 2-3 %;

[0014] The plant fiber is one or any mixture of field crop straw, sedge, corncob and bagasse;

[0015] Described poultry and livestock manure is one or any mixture of pig manure...

Abstract

The invention provides a preparation method for nano compound fertilizer. The method comprises the steps of weighing formula amount of raw material in part by weight, smashing field crop straw into powder, mixing and uniformly stirring animal dung and the field crop straw powder, to be stacked in a fermenting tank and to be conducted to wet fermentation, putting fermentation products and mixture into a reaction kettle to be dissolved with water, stirring and mixing the fermentation products and mixture to be reacted for 2 hours at 100 to 120 DEG C, filtering solution with a 200-mesh sieve after mixing process to remove residue, and adding nano ferrous sulphate and nano carbon into the filtered solution in percent by weight to be uniformly stirred, so as to obtain final products. Statistics show that by applying the compound fertilizer, the seeding ratio can reach 92 percent, applying nanometer additive promotes plants to absorb potassium and improves the absorption efficiency of potash fertilizer, the amplification is 11 percent, the ratio of disease infection is reduced by 3.1 percent, the ratio of insect damage infection is reduced by 4.1 percent, and the stimulation ratio reaches 6.5 percent.

Description

technical field [0001] The patent of the present invention relates to a preparation method of a compound fertilizer, in particular to a preparation method of a nanometer compound fertilizer. Background technique [0002] At present, there are some difficult problems in the application of fertilizers, such as the low utilization rate of fertilizers, the pollution of the ecological environment caused by excessive application of chemical fertilizers, etc.; in addition, dissolved organic carbon is an active substance in soil or water ecosystems. The composition and form transformation of various microorganisms and various nutrients in soil or water play an important role, and at the same time have a profound impact on the biogeochemical cycle and the toxicity and migration of heavy metals in the surface ecosystem. In view of the above problems, the present invention studies nano-additives and produces nano-scale materials, which not only have adsorption, dispersibility, rheology...
