Abstract

The invention discloses a preparation method of high-efficiency foliar fertilizer, and belongs to the field of fertilizer. According to the preparation method, with biogas slurry as a raw material, polyacrylamide and polyferric sulfate are added, wherein cationic polyacrylamide is a linear polymer compound and an iron flocculant, and since cationic polyacrylamide has various kinds of active radical groups, cationic polyacrylamide and various substances can be subjected to affinity and adsorption to form hydrogen bonds to mainly flocculate colloids with negative charges; meanwhile, colored substances in the biogas slurry are decolorized, deodorization and deoiling are conducted, ammonia, methane, hydrogen sulfide, organic amine, other benzene and nitrogen-containing compounds in the biogasslurry are removed, and the damage to the environment and the human body is reduced. The preparation method solves the problems that through long-term application of existing foliar fertilizer, the pollution to water soil can be caused, nutrients are easily lost, and the fertilizer effect time is short.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a preparation method of high-efficiency foliage fertilizer. Background technique [0002] In the crop planting industry, chemical fertilizers and manure are generally used to promote crop production, which can increase crop yields and improve crop varieties to a certain extent. However, the extensive use of chemical fertilizers and farmyard manure will cause damage to the soil, thereby destroying the ecological environment. In addition, this traditional method of fertilization will be affected by weather conditions. my country's agriculture is in a period of structural adjustment, from the one-sided pursuit of output to the goal of high yield, high quality, high efficiency, maintaining ecological balance, and sustainable development. In order to achieve this goal, many new fine varieties and new farming techniques must be used, and the scientific and technological content ...
