Production method for lowering cadmium content in Sauropus androgynus product

2010 
The invention relates to a production method for lowering cadmium content in a Sauropus androgynus product. After soil is leveled and is in deep ploughing, the pH value of the soil is determined and then adjusted; after a ridge is ploughed, base fertilizer is applied; Sauropus androgynus is planted after covering surface soil and is irrigated and watered at regular time; when tender tips grow on the plant, a tender tip of which the length is 12 cm is picked to obtain the Sauropus androgynus product with low cadmium content; the base fertilizer is formed by mixing fermented high-protein organic fertilizer, superphosphate and ant ash or by mixing fermented high-protein organic fertilizer, superphosphate and lemery salt. The invention has simple operation method, effectively fixes cadmium ions in soil by regulating the pH value of soil and applying high-protein organic fertilizer, reduces the possibility that the root of the Sauropus androgynus adsorbs cadmium ions from oil so as to effectively control cadmium content in the Sauropus androgynus while ensuring yield. The produced Sauropus androgynus product has stable and safe quality, can be applied on small-area or large-scale production cultivation and has strong operability.
