Problems solved by technology

[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

Abstract

The invention provides a nanometer compound fertilizer. Raw materials in a formula amount are selected according to certain weight parts and are mixed and placed into a reaction kettle; the raw materials are dissolved with water to be stirred, mixed and reacted for 2 hours at the temperature of 100-120 DEG C; after the finish of the mixing process, residues are removed by using filtering solution of 200 mesh sieves; and nanometer ferrous sulfate and nanometer carbon are added into the filtering solution according to the weight percentage, and the mixture is stirred uniformly to obtain a final product. According to the statistics, after the compound fertilizer is applied, the seed emergence rate is up to 92 %; with the application of a nanometer addictive, the absorption of potassium elements to plants is accelerated, and the amplitude increase of potassium fertilizer absorption efficiency is increased by 11 %, the ratio of disease infection is reduced by 3.1 %, the infection of insect attach is reduced by 4.1 %, and the yield increase ratio is up by 6.5 %.

Description

technical field [0001] The patent of the present invention relates to a compound fertilizer, in particular to a nano 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, porosity and surface acidity, but also have the sur...
