Problems solved by technology

[0002] 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
[0003] 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.
[0004] Potted flowers are used as interior decoration, and at the same time, the oxygen released by photosynthesis during the growth process plays a very active role in human health; there are many slow-release fertilizers used for flower bonsai at home and abroad, and they can play an effective role. There are no public reports on the new varieties of slow-release fertilizers with slow-release effect and active oxygen release

Embodiment 1

[0032] A kind of oxygen-increasing slow-release fertilizer, composed of 98% carbamide peroxide-beta-cyclodextrin inclusion complex, 0.5% carbamide peroxide (Perurea: CO(NH 2 ) 2 ·H 2 o 2 ) and 1.5% of β-cyclodextrin, in molar percentage; wherein the carbamide peroxide-β-cyclodextrin inclusion compound has carbamide peroxide as the inner core and β-cyclodextrin as the outer layer. The oxygen-enhancing slow-release fertilizer and MnO 2 Be 1:20 to mix as medicine layer by mass ratio, described aerobic slow-release fertilizer and MnO 2 The composition layer is placed on the loam layer of the flower bonsai, below the soil layer, and watered according to the normal watering method of the bonsai. The slow-release fertilizer fertilizer effect is fast, and there is new ecological oxygen [O] in about 10 seconds after application. release, while its fertilizer effect is stable and long-lasting, and it lasts for about 280 hours at 100g (the net content of carbamide peroxide).

Embodiment 2

[0034] A kind of oxygenation slow release fertilizer, by 95% carbamide peroxide-beta-cyclodextrin clathrate, 4% carbamide peroxide (Perurea: CO(NH 2 ) 2 ·H 2 o 2) and 1% of β-cyclodextrin, in mole percent; wherein the carbamide peroxide-β-cyclodextrin inclusion compound is composed of carbamide peroxide as the inner core and β-cyclodextrin as the outer layer.

Embodiment 3

[0036] A kind of oxygenation slow release fertilizer, by 92% carbamide peroxide-beta-cyclodextrin clathrate, 4% carbamide peroxide (Perurea: CO(NH 2 ) 2 ·H 2 o 2 ) and 4% of β-cyclodextrin, in mole percent; wherein the carbamide peroxide-β-cyclodextrin inclusion compound is composed of carbamide peroxide as the inner core and β-cyclodextrin as the outer layer.

Abstract

The invention relates to an oxygen-enriched controlled-release fertilizer which is characterized by consisting of a urea peroxide-beta-cyclodextrin complex with an effective quantity, urea peroxide (Perurea: CO(NH2)2.H2O2) and beta-cyclodextrin, wherein in the urea peroxide-beta-cyclodextrin complex, urea peroxide is used as an inner core, and beta-cyclodextrin is used as an outer layer. The oxygen-containing activity amount of the controlled-release fertilizer is high and can reach 17%-20%; and after being applied, the oxygen-enriched controlled-release fertilizer can continuously, moderately, stably and controllably release oxygen, and 100g of the fertilizer (the net content of Perurea) can continuously release oxygen for 300 hours. The controlled-release fertilizer has the advantages of slow, moderate and stable oxygen-enrichment mode, strong activity degree and strong antiseptic property, and is easy to eliminate the diseases in bonsai, thereby effectively improving the normal survive rate of a bonsai plant; and simultaneously, the oxygen-enriched controlled-release fertilizer has the effects of indoor oxygen enrichment, cleaning and disinfection; and compared with the relatedresearch results reported at present and novel products supplied by a market, the oxygen-enriched controlled-release fertilizer has incomparable superiority.

Description

technical field [0001] 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 and its preparation method and application.
