Ao Miao Fertilizer and its use

The secret fertilizer developed by American Scott company is a kind of special fertilizer for horticultural plants. Recently, China has introduced a large number of secret fertilizer, which has been tried out by some scientific research institutions and flower farms in Guangzhou, and it is found that it is suitable for shade plants, orchids, bonsai and so on.

The main components of Aomiao fertilizer are 14% nitrogen (N) (of which 7.2% nitrate nitrogen and 6.8% ammonium nitrogen), 14% phosphorus (P2O5), 14% potassium (K2O), and a variety of trace elements suitable for the growth and development of ornamental plants. The biggest difference between the secret fertilizer and the ordinary compound fertilizer is that it is coated with a special medium which can control the slow release of nutrients. Therefore, the secret fertilizer can gradually release the nutrients needed by the plant in the process of plant growth, and the fertilizer utilization efficiency can be greatly improved. According to the experiment of Guangzhou Institute of Agricultural Science and Technology, imported compound fertilizer was widely applied to shade plants such as white palm, green emperor, Hulk and so on, with a fertilizer use efficiency of about 30% and a fertilizer efficiency of about 28 days), while with the application of secret fertilizer, the fertilizer utilization efficiency reached 99%, and when the average soil temperature was 21 ℃, the fertilizer efficiency was about 120 days. According to the technical data of the Netherlands, if the average soil temperature is 16 ℃, the fertilizer effect period of Mimi fertilizer can be more than 180 days. Because the secret fertilizer is coated with a special medium, it will not hurt the root even if it is in direct contact with the plant root.

Aomiao fertilizer is very easy to use, such as pseudo-planting of tissue culture seedlings, flower seed sowing or plant pots, it can be mixed with wall substrate to plant plants, with a usage of about 120 grams per cubic meter to 150 grams. For potted plants, secret fertilizer can be scattered on the flowerpot surface soil or shallow buried pot soil, 15 cm in diameter flowerpot apply 2 grams, 20 cm flowerpot apply 3 grams, 30 cm flowerpot apply 5 grams. The usage of seedling bed is 30 grams per square meter. (Guangdong-Song Guoxiong)
