Description
Technical field
The utility model relates to field of plant growing technology, especially relates to a kind of UF foamed plastics cultivation matrix and cultivation method thereof.
Background technology
In recent years, along with growth in the living standard, people require also more and more higher to the greening level of inhabitation and living environment.Beautiful surrounding enviroment that are full of plant of demand not only, also wish in the room, to create a comfortable human settlement, thirsting for especially is the family of oneself in the city of clamour, comprise indoor, outdoor, balcony, courtyard, balcony, passage, corridor or the little garden of oneself, inject green life.To the requirement that improves of living environment, to the demand of fresh and healthy vegetables, to the yearning of city agro-farming, use widely cultivation technique without soil to satisfy these demands both at home and abroad.
For the vegetable growing aspect, various channelization cultivations, floating cultivation, container culturing etc. are already attempted in the soilless culture of China.These soilless culture methods and facility thereof exist the dependence to container, the loaded down with trivial details and professionalization of management of management to require the problems such as strong.Still can adopt for extensive intensive production, but when entering family and carrying out small-scale utilization, need to improve these patterns and facility.The family's vegetables mode of production that adopts at present is a kind of to be the conventional planar cultivation, uses the matrix such as earth or the peat composed of rotten mosses, cinder, vermiculite, perlite, cooperates some containers such as flowerpot to cultivate, and the method cultivation takes up room large, manages loaded down with trivial details; Another kind method is to use small-sized water planting equipment, and the vegetables output of the method is subject to the moulding of container, and output is not high and equipment price is expensive.
For the vertical planting aspect, many plants need to be planted in vertical elevation, and also having a kind of is the three-dimensional contouring plantation, and namely carrying out specially with plant, combination shaping goes out graphic design attractive in appearance or body.Plantation for these types, more currently used matrix such as slag, vermiculite etc., must carry out the very high construction of complexity, maintenance and maintenance, and effect neither be very desirable, there are problems, such as using facility or equipment that matrix is fixed moulding for reaching the facade requirement, and the matrix water retention property that uses at present is poor, must repeatedly water, cause the waste of water resource, simultaneously matrix is washed away in the process of watering and is taken away nutrition and some host materials that run off cause environmental pollution.Use based on the restriction of above planting type and matrix and to limit, be badly in need of at present a kind of plastic fixedly body matrix that has, require its easy to use and environmental protection, attractive in appearance, economize on resources.
The water-absorbing resin that is used for now the plant water keeping function is many to be imbedded undergroundly for plant provides slowly-releasing moisture in the arid area, perhaps cooperate container to provide moisture for fresh cut-flowers etc., uses water-absorbing resin to rarely have research for vegetable soilless culture and vertical planting field.
The utility model content
