Abstract

The invention discloses a biomass charcoal high efficiency controlled release fertilizer, and belongs to the technical field of agriculture. The biomass charcoal high efficiency controlled release fertilizer is composed of, by weight, 70 to 85 parts of biomass charcoal, 10 to 15 parts of a microbial agent, 15 to 25 parts of maize straw particle, 5 to 10 parts of urea, 6 to 12 parts of potassium sulphate, 6 to 12 parts of potassium manganate, 7 to 13 parts of a binder, and 10 to 15 parts of attapulgite. According to a preparation method, biomass charcoal is taken as a packaging material; cost is low; raw material resource is wide; composition is reasonable; no toxic substance is generated; no environmental pollution is caused by the biomass charcoal high efficiency controlled release fertilizer; and the biomass charcoal high efficiency controlled release fertilizer is a safe and healthy controlled-release fertilizer.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a biochar high-efficiency slow-release fertilizer. 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. At present, organic polymer-coated slow-release fertilizers can slow down nutrient release and improve fertilizer use efficiency, which has been widely recognized. 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 become a research hotspot in this field to seek membrane materials that are environmentally friendly, inexpensive, and have good sustained-release effects. Biocha...
