Problems solved by technology

The nutrient solution is prepared by dissolving quick-acting fertilizers such as NPK in water and applying it with water. Clogging, 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 fertilizer input cost is not low

Abstract

The invention discloses a coated release-controlled fertilizer of pot-cultured anthurium and a preparation method thereof. On the basis of pure nitrogen, the specially-use fertilizer is composed of an L-shaped release-controlled composite fertilizer accounting for 65-85% and an S-shaped release-controlled composite fertilizer accounting for 15-35%. A polymer coating layer of the L-shaped release-controlled composite fertilizer includes polyethylene, regenerated polypropylene, talcum powder and a multiple fertilizer. The polymer coating layer of the S-shaped release-controlled composite fertilizer includes polyethylene, regenerated polypropylene, talcum powder, corn starch, calcium powder and a multiple fertilizer. The preparation method of the release-controlled specially-use fertilizer includes the steps of spraying the components of the polymer coating layers in the L-shaped release-controlled composite fertilizer and the S-shaped release-controlled composite fertilizer onto surfaces of composite fertilizer granules and then mixing the components. The release-controlled fertilizer is effectively reduced in fertilization times, saves labor intensity, reduces the content of nitrogen, phosphorus and potassium and such nutrients in leachate, is reduced in fertilizer waste, is reduced in pollution risk of nutrient leaching on surrounding river and underground water, and has a high application value on fertilization of the pot-cultured anthurium.

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...
