 Humic acid complex amino acid import 
 BB fertilizer 
 Advantages: ① full of nutrients, high concentrations of this section yield significant targeted. It's always more than 52% of nutrients in general, the current domestic fertilizer on the market more active ingredients in 25% of total imports of fertilizer nutrients more than 45% -48%, but imports of fertilizer nutrient ratio (N: P2O5: K2O = 15:15:15) with a high proportion of phosphorus, resulting in greater waste of nutrients. BB-specific fertilizer nutrient ratio in the light of the characteristics of crop fertilizer based on soil nutrient supply reference to the local conditions proposed, both scientific and targeted. 
 ② pollution. 
 ③ flexible formula, according to crop nutrition, soil fertility and production levels in different conditions and flexible to change, to make up for the general general-purpose fertilizer nutrients due to a fixed ratio and likely to cause some kind of nutrient deficiencies or excess drawback. 
 BB basal and top dressing fertilizer can be done, because solubility, the table should do the basal applied, should not be applied too deep soil; fruit, tea, vegetables should not use BB fertilizer applicator, should bar facilities and fertilizing from the seeds and crop root 3 to 5 cm, applied after mulch, fertilizer can be applied watered. Mushi amount of 60% as long as the imports of fertilizer.
