Efficient magnetic slow controlled release fertilizer favorable for improving quality of asparagus lettuce, and preparation method thereof

Abstract

The invention discloses an efficient magnetic slow controlled release fertilizer favorable for improving the quality of asparagus lettuce. The efficient magnetic slow control release fertilizer is prepared from the following ingredients: tea tree nutshell-based biomass fuel, hematite iron ore, oil shale, mesoporous lanthanum phosphate, nanometer sea-foam stone powder, plant ash, dry beer vinasse, active yeast powder, calcium gluconate, chenodeoxycholic acid, salicylic acid doped polypyrrole nano-particles/alginate hydrogel, nanometer magnetic fluid, a proper quantity of micromolecule group magnetized water and the like. According to the fertilizer, a coating material with the efficacies of magnetic slow control and release acceleration is adopted to coat pulp liquid which contains lignin, the nanometer sea-foam stone powder, the plant ash, the dry beer vinasse and poplar leaves and is combined with fermentation particle fertilizer prepared from nutrient solution to prepare the slow release fertilizer. Through a magnetic effect, a slow release effect is improved, the fertilizer is organic matter fertilizer and is rich in nutrition, the contents of protein and carbohydrate of a plant can be improved, the absorption and the utilization of the asparagus lettuce on small organic molecules can be accelerated through a magnetic adsorption effect, the quality of a crop product is effectively improved, and the crop product can be accelerated to be efficiently cultivated.

Description

technical field [0001] The invention relates to the technical field of magnetic slow-release fertilizers, in particular to a high-efficiency magnetic slow-release controlled-release fertilizer that helps improve the quality of lettuce and a preparation method thereof. Background technique [0002] At present, the slow-release coated fertilizer complies with the call of the times and the demand of the market, and is developing in the direction of new type, environmental protection, high efficiency, low cost and sustainable development. Both large and efficient companies are actively developing slow-release fertilizers. Currently, there are two bottlenecks: one is high production costs, and the other is slow-release and biodegradable properties of slow-release film materials. The overall utilization of fertilizers The rate is less than 50%. More importantly, slow-release fertilizers in the market have poor slow-release effects, and most of them focus on slow-release performanc...

[0002] At present, the slow-release coated fertilizer complies with the call of the times and the demand of the market, and is developing in the direction of new type, environmental protection, high efficiency, low cost and sustainable development. Both large and efficient companies are actively developing slow-release fertilizers. Currently, there are two bottlenecks: one is high production costs, and the other is slow-release and biodegradable properties of slow-release film materials. The overall utilization of fertilizers The rate is less than 50%. More importantly, slow-release fertilizers in the market have poor slow-release effects, and most of them focus on slow-release performance. Controlled-release fertilizers with higher slow-release requirements are relatively rare.

However, due to the fact that magnetized fertilizers usually use magnetized processors for magnetization treatment and later stages, they have not been effectively promoted.

[0004] Nano-fertilizer is a new thing. It is a high-tech researched and developed by combining nanotechnology, pharmaceutical microcapsule technology and chemical microemulsion technology. Or the nano-small size effect of the materials used makes the fertilizer have a magnetic effect as a whole, so that nutrients are more easily absorbed by plants, which is beneficial to plant growth. However, due to cost constraints, it has not been widely promoted.
