Organic coated fertilizer for planting eriobotrya japonica and preparation method for organic coated fertilizer

Abstract

The invention discloses an organic coated fertilizer for planting eriobotrya japonica and a preparation method for the organic coated fertilizer. The organic coated fertilizer is prepared from the following raw materials by weight (in parts by weight): a 4-6wt% HCl solution, zinc oxide powder, citric acid, rice hull ash, ardealite, activated carbon, bagasse, peanut shells, pomelo peels, ammonium molybdate, magnesium sulfate, potassium dihydrogen phosphate, an EM microbial agent, goat fecal pellets, lotus pond sludge, cellulose homogenate and water. The organic coated fertilizer is applicable to the planting of the eriobotrya japonica; the organic coated fertilizer gives priority to organic fermented materials, and the consumption of inorganic constituents is lowered, so that the organic coated fertilizer is beneficial to soil and is particularly applicable to fruit trees, i.e., long-term-growing plants, the content of organic matters in the soil is increased, the physiological activity of the fruit trees is promoted, the age limit of the fruit trees is prolonged, and the fruit trees are not prone to diseases and insect pests; and a proper amount of inorganic nutrients added are subjected to complexing by the citric acid, so that absorption is facilitated.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an organic coated fertilizer for planting loquats 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 powder...

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
