Hydrophobic long-acting modified oil-coated organic fertilizer and preparation method thereof

Abstract

The invention discloses a hydrophobic long-acting modified oil-coated organic fertilizer and a preparation method thereof. The hydrophobic long-acting modified oil-coated organic fertilizer is prepared from the following materials in parts by weight: n-hexane, epoxidation modifier, sesame dregs, cracklings, rape dregs, soy sauce residue, peat, fish bone powder, EM (effective microorganism) bacterium agent, diatomite, plant ash, cottonseed hull, duck feces, quartz grain, humic acid powder, ammonium molybdate, mulberry leaves and an appropriate amount of water. Crude grease is extracted from discarded material with high grease content, and is modified to be used as coating for organic matter, which can play a good role of preventing loosening, consequently, the hydrophobic long-acting modified oil-coated organic fertilizer can keep the shape of particles for a long time after being kept still, and does not absorb moisture when exposed in the air, and the hydrophobic long-acting modified oil-coated organic fertilizer is particularly suitable for crops with high water retention capacity, such as paddy rice, sugarcanes and water chestnuts.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a hydrophobic long-acting modified oil-coated organic fertilizer and a preparation method thereof. Background technique [0002] Nowadays, many organic fertilizers are directly used for the release of crops. Organic fertilizers are generally powders. The reason is that the fermentation is relatively thorough and the particle size is small. The advantage of this is that it is convenient to apply, and the fertilizer can be directly applied to the fertilization point. And small particles of organic matter are easily absorbed by crops. However, this approach inevitably brings some disadvantages. On the one hand, due to the small particle size of organic fertilizers, for the soil that is too soft, the gaps in the soil are large, and the fertilizer can easily penetrate deep into the soil, exceeding the absorption area of ​​the crop root system. range, and if the soil i...

However, this approach inevitably brings some disadvantages. On the one hand, due to the small particle size of organic fertilizers, for the soil that is too soft, the gaps in the soil are large, and the fertilizer can easily penetrate deep into the soil, exceeding the absorption area of ​​the crop root system. range, and if the soil is too hardened, organic fertilizers are not conducive to infiltration into the soil, and the function of root system absorption is out of the question. The most important thing is that the fertilizer stays on the upper surface of the soil for a long time, once it is watered or it rains The effect of weather and water flow is likely to wash away the organic fertilizer, causing a large amount of loss, and the effect is even worse. It is difficult to control the proper soil looseness between soft and hardened soil.
