Problems solved by technology

In addition, some elements are released into the soil by chemical fertilizers and then dissolved by groundwater or rainwater and absorbed by plant roots. However, some elements such as calcium and magnesium may form insoluble substances when they encounter conditions such as carbonate radicals when they are dissolved in water, and thus remain in the soil. Not absorbed by plants, resulting in low fertilizer utilization
[0003] In the prior art, chelating trace element fertilizers or complex trace element fertilizers are prepared by direct compounding, which improves water solubility, but also increases the loss rate. Most of these fertilizers are applied in the form of water-soluble fertilizers, but such The amount of use is small, it needs to be applied multiple times, the workload is heavy, and the field operation is difficult

Abstract

The invention relates to a soil improvement fertilizer for promoting absorption of plant trace elements and a preparation method thereof, and belongs to the technical field of fertilizer preparation. According to the preparation method, the raw materials for preparation comprise urban landscaping garbage, compressed dry residues of waste vegetable leaves in the vegetable market, dry residues obtained after semi-fermentation of kitchen garbage, solid residues left after harmless treatment of animals and dry residues obtained after fermentation of urban human excrement, the chemical combination state of soil microelements is adjusted, a post-organic chelation or complexation mode is adopted, and therefore, the absorption of plants on trace elements is improved. The fertilizer prepared by the preparation method disclosed by the invention has a slow release effect and a good trace element absorption effect.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a soil improvement fertilizer that promotes the absorption of plant trace elements and a preparation method thereof. Background technique [0002] The soil environment in which crops grow is complex, and there are not only various macroelements, but also some medium and trace elements. Most of these elements exist in the form of salt in soil, some are soluble in water, some are not easily soluble in water, and plant growth is closely related to the chemical composition, type and content of these elements. Furthermore, plants need these elements, but plants cannot accept them in any form. For example, plants need nitrogen, which can absorb urea or ammonium nitrate, but cannot absorb nitrogen. In addition, some elements are released into the soil through chemical fertilizers and then dissolved by groundwater or rainwater and absorbed by plant roots, but some element...
