Efficient magnetic sustained-/controlled-release fertilizer for sweetening watermelons and preparation method therefor

Abstract

The invention discloses an efficient magnetic sustained- / controlled-release fertilizer for sweetening watermelons. The efficient magnetic sustained- / controlled-release fertilizer contains the following ingredients in parts by weight: walnut shell based biomass fuel, fly-ash magnetic beads, mesoporous zirconium-sodium phosphate, coal humic acid, molasses waste residues, alfalfa submicron powder, grease saccharified residues, waste alcohol sediment liquid, an organic active silicon fertilizer, biological fungi, bioactive enzymes, photosynthetic bacteria, polyacrylate starch semi-interpenetrating-network aquagel, nano magnetic liquid, a proper volume of small-molecular-group magnetized water, and the like. According to the efficient magnetic sustained- / controlled-release fertilizer, the sustained-release fertilizer is prepared through wrapping fermented granulated fertilizers, which are prepared from the coal humic acid, a nutrient solution and the like, with a coating material with magnetic sustained release and release promoting effects; the sustained-release effect is improved through a magnetic effect; the fertilizer is rich in nutrients for promoting photosynthesis and improving sweetness, so that the growth and development of watermelon plants can be promoted, and the fruit setting rate is increased; and meanwhile, the absorption of the watermelons to organic micromolecules can be promoted through a magnetic adsorption effect, the disease resistance is high, the yield is high, the flesh color is bright-colored, the flesh is tender, the moisture content is high, and the efficient cultivation of the watermelons 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-release fertilizer for sweetening watermelons 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-r...

[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.
