Abstract

The invention relates to a compound fertilizer for sweet potato, belonging to the technical field of plant fertilizers. According to the compound fertilizer for the sweet potato, waste concrete is used as a carrier; main fertilizer components are an organic fertilizer and biogas residue leavening; and meanwhile, the compound fertilizer also contains diatomite which can be used for not only loosening soil but also providing nutritional components and is prepared by process steps such as repeated soaking and air-drying. Thus, the compound fertilizer for the sweet potato contains a large amount of nitrogen, phosphorus and potassium, meanwhile contains amino acid, enzyme, amide, cytokinin and beneficial biological bacteria and can be used for providing complete nutritional components for the sweet potato and improving soil environment. The sweet potato cultivated by using the compound fertilizer for the sweet potato has higher content of trace nutritional components and can meet dietary standard of modern people better.

Description

technical field [0001] The invention relates to a fertilizer for plants, in particular to a compound fertilizer for sweet potatoes. Background technique [0002] Sweet potato is one of the four major food crops in northern my country. It has the advantages of strong adaptability, drought tolerance, less pests and diseases, and high yield. It is an ideal high-efficiency crop. Its growth process requires not only nitrogen, phosphorus, potassium and other fertilizers, but also many trace elements, organic nutrients and beneficial biological strains. At the same time, the root system and root tuberous expansion of sweet potato requires deep and thick loose soil conditions. However, the current sweet potato fertilizers only pay attention to the content of nitrogen, phosphorus and potassium, but ignore the improvement of the root system of sweet potato to trace elements and fertilizer utilization efficiency, and do not pay attention to the improvement of the soil environment. C...
