Abstract

The invention discloses a biomass-charcoal-enveloped colloid-rich fertilizer and a preparation method thereof. The fertilizer is prepared from the raw materials of, by weight, 20-30 parts of rape straw, 25-40 parts of corn straw, 10-15 parts of agar powder, 2-3 parts of an EM inoculant, 10-20 parts of lotus pond slit, 20-35 parts of Chinese herbal medicine residue, 10-16 parts of poultry feather, 10-20 parts of potassium bicarbonate, 20-35 parts of a calcium-magnesium-phosphorous fertilizer, 6-10 parts of calcium chloride, 10-16 parts of sodium fulvate, 20-30 parts of ammonium chloride, 5-7 parts of an adhesive, and a proper amount of water. According to the invention, the Chinese herbal medicine residue, poultry feather and the like are shortly fermented with microbial strains, and the agar powder is added for improving soil colloid content. When colloid content is improved, soil particles can be cemented to form pellets, and water retention, fertilizer retention and compaction prevention capacities are improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a biochar-coated colloid-rich fertilizer and a preparation method thereof. Background technique [0002] Slow-release fertilizers can not only improve fertilizer use efficiency, but also reduce the negative impact of fertilization on the environment, which has attracted extensive attention of scholars in recent years. The current research on coated slow-release fertilizers mainly focuses on the selection and development of coating materials. Organic polymer coated slow-release fertilizers can slow down nutrient release and improve fertilizer use efficiency, which has been widely recognized. [0003] However, most of them use fat-soluble substances in the production process, which is easy to cause pollution to the environment after application, and the price is high, which limits the popularization and application of this type of fertilizer. Therefore, it has beco...
