Pot flower slow-release coated fertilizer and preparation method thereof

Abstract

The invention discloses a pot flower slow-release coated fertilizer and a preparation method thereof. The pot flower slow-release coated fertilizer is prepared from the following raw materials (in parts) by weight: a 4-6wt% HCl solution, zinc oxide powder, humic acid powder, maleic anhydride, glauconite, shells, micalex, moss soil, titanium dioxide, indoleacetic acid, chitosan, sodium selenite, zinc chloride, peat, potassium sulfate, cellulose homogenate and water. Generally, pot flowers do not need too much soil, or else root system breath and water content can be affected; as mineral-enriched stone is calcined and the calcined material is crushed into powder, the stone powder contains a great amount of minerals, and the minerals can be easily dissolved out after being quenched and are natural minerals, the content of inorganic trace elements in the fertilizer disclosed by the invention can be reduced, and flowers can be promoted to grow and can be kept vigorous.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a slow-release coated fertilizer for potted flowers and a preparation method thereof. Background technique [0002] The usual fertilizer coating has the initial sulfur-coated urea technology, and then the Japanese-style thermosetting resin coating technology. The basis of these resin materials is mainly polyolefin, which is formed by grafting and copolymerizing with some organic polymers. The high polymer is mixed with a certain amount of inorganic mineral stone powder to make a coating material. The inorganic mineral stone powder used includes silicon, sulfur, gypsum, phosphate, zeolite powder, diatomaceous earth, bentonite, etc. The United States first successfully developed sulfur Coated urea, the film layer is composed of sulfur-coated layer, sealing layer and powder coating layer, which occupies an important position in today's sulfur-coated slow-release powd...

Problems solved by technology

[0003] But the disadvantages are obvious: although the stone powder coating fertilizer can improve the soil mineral quality, it needs the addition of chemical organic matter to bond, mainly the addition of resin, but the preparation of slow-release fertilizer, the resin binder used in the coating varies. The proportion, addition amount and selection of types are problems. Improper control will affect the timely supply of fertilizers. Slightly improper control will cause the coating of stone powder to be easily cracked by moisture, sandy soil, and reduce the relative proportion of humus in the soil. Water and soil erosion is very unfavorable for long-term planning; on the other hand, the coating material of stone powder is used, and the stone powder itself has a certain thickness, which seriously affects the real effective content of the coated fertilizer. If the content of added nutrients is increased, the fertilizer will inevitably increase. Particle size, very unfavorable for dissolution and fertilizer balance issues
