Oxygen-increasing slow-release fertilizer

Abstract

The invention relates to an oxygen-increasing slow-release fertilizer. The fertilizer is prepared from a urea peroxide-beta-cyclodextrin inclusion compound, urea peroxide (Perurea: CO(NH2)2.H2O2) and beta-cyclodextrin which are in effective quantities, wherein the urea peroxide-beta-cyclodextrin inclusion compound takes urea peroxide as a kernel and takes beta-cyclodextrin as an outer layer. According to the slow-release fertilizer disclosed by the invention, the oxygen content is high and can reach 17-20%; and after the slow-release fertilizer disclosed by the invention is used, the oxygen release is sustained, mild, stable and controllable and can sustain 300 hours per 100g of urea peroxide in net content. The slow-release fertilizer disclosed by the invention has the advantages that the oxygen release manner is slow, mild and stable, is stronger in activity and strong in disinfection and can be used for easily eliminating diseases and pests from potted landscapes, so that the normal survival ratio of potted plants is increased effectively; and meanwhile, the slow-release fertilizer disclosed by the invention has effects on increasing, disinfecting and cleaning indoor oxygen and has incomparable superiority compared with currently reported relevant research results and new products on the market.

Description

[0001] The application of the present invention is a divisional application with the application number 201110127538.5, the application date of May 17, 2011, and the title of the invention "an oxygen-increasing slow-release fertilizer and its preparation method and application". technical field [0002] The invention belongs to the field of chemical oxygenation and slow-release fertilizers, in particular to a chemical oxygenation and slow-release fertilizer suitable for indoor potted ornamental plants. Background technique [0003] The existing slow-release fertilizer is to coat the active ingredients to achieve slow release, and the composition of the coating layer is complex, which has a certain destructive force on the soil after application; if the existing slow-release fertilizer is applied on a large scale, the impact on the soil will be Dispersed, the regulating function of the soil itself can slowly digest this destructive power, and if the existing slow-release ferti...

[0003] The existing slow-release fertilizer is to coat the active ingredients to achieve slow release, and the composition of the coating layer is complex, which has a certain destructive force on the soil after application; if the existing slow-release fertilizer is applied on a large scale, the impact on the soil will be Dispersed, the regulating function of the soil itself can slowly digest this destructive power, and if the existing slow-release fertilizer is applied to bonsai plants, because the bonsai soil area is small, the destructive power to the soil will be amplified, Great impact on bonsai soil

The existing potted flowers are mainly fertilized with inorganic fertilizers, which are highly effective, difficult to control the amount of application, and easy to burn seedlings; while organic fertilizers have not been specially treated and are easy to deteriorate and cause small environmental pollution; at present, slow-release fertilizers are also used in potted flowers at home and abroad. The application of fertilizers makes the fertilizer efficiency more stable and less polluting to the environment, but in general its slow-release efficiency is not ideal. At the same time, the existing slow-release fertilizers have great destructive power to the bonsai soil, which may easily cause problems such as soil compaction and fertilizer efficiency decline.
