Efficient magnetic controlled release fertilizer capable of increasing fruiting rate and yield of cotton and preparing method of efficient magnetic slow controlled release fertilizer

Abstract

The invention discloses efficient magnetic controlled release fertilizer capable of increasing the fruiting rate and the yield of cotton. The efficient magnetic controlled release fertilizer comprises the following components of coconut shell biomass fuel, volcanic, mesoporous nickel phosphate, Chinese parasol leaves, oil bran, pine needle meal, salvinia natans powder, yeast extracts, beta-glucan, seaweed gel, anhydrite powder, DING SU, plant oil, pimacol, 4-(3-Indole)-butyric acid potassium salt, aminolevulinic acid, ethylenediaminetetraacetic acid calcium disodium salt hydrate, amino acid chelated boron copper iron zinc multi-trace-elements fertilizer, polyvinylpyrrolidone, polyaspartic acid sodium algin hydrogel, nano magnetic fluid and the like. An enveloping material with magnetic slow release and release promoting effects is adopted for wrapping the Chinese parasol leaves, the oil bran, the pine needle meal and the salvinia natans powder, the fermented particle fertilizer prepared through a nutrient solution is combined, and then the slow release fertilizer is prepared. Through the magnetic effect, the slow release effect is improved, meanwhile, the fertilizer is rich in multiple microelements including boron, copper, ferrous iron and zinc which are necessary for cotton, the pesticide application rate can be reduced, the fruiting rate and the yield of the cotton are increased, and efficient cultivation of the cotton 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 capable of improving cotton peach setting rate and yield 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-rel...

[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.
