Abstract
The invention discloses alpine plant culture media for a greenhouse. Four layers of different media are laid sequentially from bottom to top and specifically comprise a base layer, a natural soil layer, a nutrition layer and a covering layer, wherein the base layer is one or a mixture of quartz, feldspar, mica, kaolinite and granite and is 30-50 cm thick, and the particle size is 1-5 cm; the natural soil layer is prepared from alpine meadow soil or subalpine meadow soil and is 30-60 cm thick; the nutrition layer is a mixture of organic matters, inorganic minerals, inorganic fertilizer and microbial fertilizer and is 30-120 cm thick; the covering layer comprises vermiculite and/or volcanic rock and is 3-5 cm thick. The alpine plant culture media for the greenhouse is easy to produce and lower in cost and can remarkably increase the transplanting survival rate of alpine plants when applied to culture of the alpine plants as greenhouse landscape.
Description
Technical Field
The invention relates to the field of horticultural cultivation. More particularly, the invention relates to a greenhouse alpine plant cultivation medium.
Background
With the development of national economy, various landscape greenhouses using modern glass greenhouses as carriers are rapidly developed. The landscape greenhouse is a landscape space which is regulated and controlled by an artificial construction environment, meets the requirement of independent plant growth, is used for collecting plants growing in different regions, climatic conditions and living environments thereof, comprehensively shows the shapes, communities, habitats, cultures, economic purposes and the like of the plants, and is a plant cultivation facility for realizing the functions of ex-situ plant conservation, science popularization education and leisure travel of the plants.
Representative plants around the world are intensively collected and maintained in the landscape greenhouse, and rich biodiversity and characteristic landscape thereof are shown, wherein the mountain plants shown in the landscape greenhouse are abundant in various plants of genera under gentian of gentianaceae, primula of primula, and rhododendron of ericaceae.
There are several main soil types of alpine soil: subalpine meadow soil: the surface layer is provided with a 5-10 cm thick elastic turf layer, and the soil body is yellowish brown and has a slightly acidic reaction; alpine meadow soil: the thickness of the turf layer is 5-10 cm, but the turf layer is crisp, the soil body is dark, the structure is often flaky laminar, and multiple neutral reactions occur; subalpine grassland soil: the earth surface has a cluster grass root layer, the earth body is gray brown, the granular structure is adopted, the middle part of the section is provided with a calcium deposit layer, and the alkalescence reaction is carried out; mountain grassland soil: the soil body has light color, granular structure, unobvious calcium deposit and alkaline reaction.
