Active agriculture and forestry charcoal micro-nano composite soil conditioning agent and preparation method thereof

Abstract

The invention relates to a novel active agriculture and forestry charcoal micro-nano composite soil conditioning agent and a preparation method thereof, and belongs to the fields of soil conditioningagent technology and compound fertilizer technology. The novel active agriculture and forestry charcoal micro-nano composite soil conditioning agent is prepared from the following ingredients in percentage by weight: 40 to 60 percent of micro-nano active agriculture and forestry charcoal and 40 to 60 percent of other auxiliary materials, wherein the auxiliary materials are prepared from the following ingredients in percentage by weight: 25 to 35 percent of agriculture and forestry biomass waste, 15 to 35 percent of nonmetal oxysalt ore, 15 to 30 percent of natural macromolecular organic matterand 15 to 30 percent of traditional Chinese medicine. The prepared novel active agriculture and forestry charcoal micro-nano composite soil conditioning agent has relatively good soil pesticide, heavy metal harmful residue in-situ repair functions; the efficacy of soil fertility improvement and plant disease and insect pest prevention and control can be achieved.

Description

technical field [0001] The invention relates to the field of soil conditioner technology and compound fertilizer technology, in particular to a novel active agricultural and forestry biochar micro-nano composite soil conditioner and a preparation method thereof. Background technique [0002] The research on soil conditioners began at the end of the 19th century. There are more researches on natural conditioners, artificial synthetic modifiers, natural-synthetic copolymer conditioners and biological conditioners. Soil conditioners can effectively improve soil physical and chemical properties and soil nutrient status, and have a positive impact on soil microorganisms, thereby increasing the productivity of degraded soils. At present, soil conditioners have been widely used in the improvement of degraded soil, and their improvement effects are mainly reflected in: first, improving soil physical properties, enhancing soil water retention and air permeability; enhancing the avail...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the serious pollution of pesticides and heavy metals in the soil, soil compaction and other problems, the invention provides a new type of active agricultural and forestry biochar micro-nano composite soil conditioner, which integrates traditional Chinese medicine conditioning, soil joint repair and natural fertilizer. A new multifunctional composite soil conditioner fertilizer with the characteristics of new pollution-free, no residue, no toxic and side effects, wide source, degradable, and low cost
