I plant the "Songhua River" card is the use of organic and inorganic compound fertilizer in maize processing in the process of extraction of fresh organic material, the use of advanced spray granulation process refining the green organic fertilizer, no chemical composition, is the best fertilizer in cash crops, the product not only contains a certain amount of nitrogen, phosphorus, potassium basic elements, but also contains large amounts of organic matter necessary for all crops, amino acids and trace elements, is available chemical fertilizers, trace elements by efficiency, long-term dissolved organic matter as one of the high-quality fertilizer, but also has raised land, drought, disease prevention and reduction of the special effects of continuous cropping disease, and the applicability is very broad and flexible, can do basic fertilizer, top dressing and fertilization can be used to do , quality standards and used as follows: 
 Quality standard: GB1887-2002 
 Quality: 
 No. Index name Value 
 A total nitrogen content: (%) 16 
 2 K: (%) 2 
 3, the total content of organic matter: (%) 20-38 
 Total amino acid content of 4: (%) 10 
 5 Sulfur (S) content: (%) 10-13 
 Crude protein content of 6: (%) 85 
 True protein content of 7: (%) 28 
 Usage: 
 Basal fertilizer use, plowing buried 10-20 cm, a foot facilities, fertilizer use, can open bar facilities, fertilizing, watered Chong Shi, fruit trees can be opened ring fertilization. 
 Note:
