Problems solved by technology

The present invention uses citric acid and its salts as chelating ligands to carry out chelating reactions on trace elements, but simple citric acid chelating is easy to form precipitation after chelating the iron element, and it is easy to cause stratification after long-term storage , although it can partially solve the problem that trace elements are difficult to be effectively used, but the final form of the fertilizer is liquid, and flushing or spraying is the main applicable method. It cannot be used at the same time as NPK, which will cause duplication of labor and increase labor costs.

Embodiment 1

[0034] Put 20 moles of sucrose molasses into the 5000L reactor (the water content of sucrose molasses is 18%), turn on the heating, raise the temperature to 85°C, keep the temperature at 85-105°C, and turn on the stirring equipment at the same time, the stirring speed is 80r / min, 2 moles of copper sulfate crushed through a 100 mesh sieve were added to the reactor in 2 batches, and reacted for 1 hour; then 2 moles of zinc sulfate passed through a 80 mesh sieve were added, added in two batches, and reacted for 1.5 hours; Add in two batches and stir for 2 hours; finally add 2 moles of ferrous sulfate passing through a 80-mesh sieve, and react for 1.5 hours. The material is introduced into a stainless steel pool, cooled, and precipitated; after completion, the precipitate is put into a centrifuge for dehydration, and then dried by an airflow dryer, the temperature is controlled at 120°C, cooled and sieved to obtain a complex of sucrose and trace elements (sucrose copper , the sum ...

Abstract

The invention discloses a trace element sucrose complex fertilizer additive, and a preparation method and application thereof. According to the trace element sucrose complex fertilizer additive, the main ingredient is a trace element sucrose complex which is obtained by multi-component complexation reaction of cane molasses and trace elements, and the trace elements comprise copper, zinc, manganese, iron, calcium, magnesium and cobalt. The preparation method comprises the following steps: adding water-soluble salts of copper, zinc, manganese, iron, calcium, magnesium and cobalt into a solution of cane molasses at the temperature of 85-105DEG C, fully reacting to obtain a complex, finally spray-drying, crushing, screening and inspecting to obtain a finished product, and formulating a quality standard of the finished product. The additive is flexible in a using method and is mainly used as the additive for organic fertilizers, inorganic fertilizers, compound fertilizers and other fertilizers, the amount of the additive can be changed according to demands of crops, and at the adding amount of 1-5kg per ton of the fertilizer, the additive can effectively supplement the trace elements which are required in growth and development of plants, reasonably improve a soil environment, promote the development of a root system, increase production and improve economic benefits.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, in particular to a trace element sucrose complex fertilizer additive and its preparation method and application. Background technique [0002] Generally speaking, chemical fertilizers are divided into two types: macro-element fertilizers and micro-element fertilizers. Macro-element fertilizers such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, calcium fertilizer, magnesium fertilizer, sulfur fertilizer, etc., and micro-element fertilizers refer to fertilizers containing micronutrient elements. It accounts for a few parts per thousand to a few parts per million in plants, such as iron, chlorine, manganese, copper, zinc, molybdenum, boron, etc.; trace elements are equally important to crops. After years of research, trace element fertilizers are It plays an important role in the process of plant growth and development, and plays an irreplaceable role in constant fertilizer. ...
