Abstract

The invention discloses a potted anthurium-coated controlled-release fertilizer and a preparation method thereof. The special fertilizer is composed of an L-type controlled-release compound fertilizer and an S-type controlled-release compound fertilizer with a ratio (calculated by pure nitrogen) of 65-85%:15-35%. Wherein, the polymer coating layer of the L-type controlled-release compound fertilizer includes polyethylene, recycled polypropylene, talcum powder and multielement fertilizer. The polymer coating layer of the S-type controlled-release compound fertilizer includes polyethylene, recycled polypropylene, talcum powder, corn starch, calcium powder and multi-element fertilizer. The preparation method of the special fertilizer for controlled release is to spray the components of the polymer coating in the L-type and S-type controlled-release compound fertilizers on the surface of the compound fertilizer particles respectively, and mix them in proportion. The controlled-release fertilizer effectively reduces the frequency of fertilization and saves labor; it reduces the nutrient content of nitrogen, phosphorus and potassium in the eluate, reduces fertilizer waste, and reduces the risk of pollution of surrounding rivers and groundwater by nutrient leaching. It is used in potted Anthurium Fertilizer has high application value.

Description

technical field

[0001] The invention belongs to the field of fertilizers, and relates to a potted anthurium-coated controlled-release fertilizer and a preparation method thereof. Background technique

[0002] In the production of potted flowers, fertilization mainly adopts the method of watering nutrient solution. The nutrient solution is prepared by dissolving quick-acting fertilizers such as NPK in water and applying it with water. Blockage, the selection of fertilizers is very harsh, and it is not easy to use cheap agricultural chemical fertilizers on the market, many of which are expensive chemical raw materials, so the cost of fertilizer input is not low.

[0003] The fertilization method of watering the nutrient solution causes serious nutrient leaching loss. 50%-80% of the irrigation nutrient solution is lost with the infiltration of water. The nutrient leaching caused by a large amount of irrigation nutrient solution not only causes economic losses, but also aggrav...
