Problems solved by technology

For inorganic fertilizers, it mainly provides elements such as carbon, phosphorus, and potassium. Its advantages are high nutrient content, fast fertilizer effect, strong fertilizer, and can play a role in quick effect and product improvement; its disadvantage is that it generally does not contain organic matter, only It can supply crop nutrients, improve soil and cultivate soil fertility. The effect is short, the effective time is short, the fertilizer effect is not long-lasting, it is easy to volatilize, lose, wash or be fixed by the soil to cause loss, the utilization rate is low, and it will be damaged after long-term use. Destroy soil structure and reduce crop quality
Although the fertilizer contains medium and trace elements, the types and quantities contained are uncertain, and the correction and prevention of the main trace element deficiency symptoms in the soil are not targeted, and the application effect is poor

The method provided by the invention can be used for not only making full use of industrial waste, avoiding the secondary pollution and reducing the production cost, but also optimizing the efficient utilization of chemical nutrients; moreover, the method has the characteristics of wide source of raw materials, convenience in transportation and application, promotion of mechanical operation and the like as well as broad application prospect. The product can be used for improving the soil fertility and obviously increasing the crop yield.

Description

【Technical field】 [0001] The invention belongs to the field of fertilizer production. More specifically, the present invention relates to an organic-inorganic compound fertilizer containing chelated trace elements, and also relates to a production method of the organic-inorganic compound fertilizer. 【Background technique】 [0002] The content of nitrogen, phosphorus and potassium in organic fertilizers is very low, and mainly provides organic matter and other substances. It is characterized by a large amount of organic matter, which has a significant effect on improving soil and fertilization; the types of nutrients contained are comprehensive, but the content is low and the fertilizer strength is small; the time for fertilizer supply Long, slow and long-lasting fertilizer effect; can fully integrate with the soil to form an organic complex, so the loss is small and the utilization rate is high. For inorganic fertilizers, it mainly provides carbon, phosphorus, potassium and...
