 Fertilizer 
 According to crop growth characteristics and the necessary nutrients, a combination of plant nutrition, soil biology, cellular immunology, microbial theory and other theories developed root system made of high-grade fertilizer. Advanced dual-chelation, complex technology of inorganic nutrients also play a quick, long-term, utilization increased substantially. Trace elements, organic fertilizer added microbial activity, thereby achieving more efficient one, balanced nutrition fertilization
