Efficient magnetic slow controlled release fertilizer for high-quality kiwi fruits and preparation method of efficient magnetic slow controlled release fertilizer

Abstract

The invention discloses an efficient magnetic slow controlled release fertilizer for high-quality kiwi fruits. The fertilizer is prepared from tea branch based biomass fuel, maghemite, diatomite, mesoporous yttrium phosphate, defatted rice bran, grass ash, herb residues, dried lotus pond sludge powder, EM biological bacterial strain, vitamin E, abscisic acid inhibitor, hyaluronic acid gelatin/acrylamide dual-network hydrogel, nano magnetic liquid, appropriate amount of micromolecular magnetized water and the like. A coating material with magnetic slow release and release promotion efficacies is adopted for wrapping a fermented particle fertilizer prepared from medical stone, rape rotten stems, the defatted rice bran, grass ash, herb residues, dried lotus pond sludge powder and nutrient solution to obtain the slow-release fertilizer, a slow-release effect is improved by a magnetic effect, and the fertilizer is an organic fertilizer intrinsically and rich in nutrition and is capable of making kiwi fruit plants robust; due to the magnetic adsorption effect, organic micromolecule adsorption and utilization of the kiwi fruits can be promoted; antibacterial and anti-shedding efficacies are achieved, quality of the kiwi fruits is comprehensively improved, and efficient cultivation of the kiwi fruits is promoted.

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 fertilizer for high-quality kiwifruit 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 performance. Controlled-release f...

[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.
