Some Words about Special Greenhouses for Definite Plant Species.

In this article we want to speak about special greenhouses, arranged for some plant species, such as orchid, special greenhouses for the culture of roses for cutting, etc.

In the orchid greenhouses for most orchids it is needed a lot of light, freshness and air humidity.

In greenhouses for the culture of roses for cutting the special soils of sod land are arranged. Roses in this case are put in the ground without the pots.

Finally, in the greenhouses that are used for winter maintenance of plants such as citrus, pine, evergreen and some others to avoid the heat of direct sunlight, the ceiling is made dark, and the plants are lighted by the side through vertical glass wall facing to north, while glazing from both sides - facing east and west.

Interior fittings of greenhouses depend on the purpose (plant breeding, culture, or forcing the plants), on the method of application of the areal size that, in turn, is connected with the method of culture.

In the present types of greenhouses there are two major ways to apply the area:

1. Rack way - when the culture is grown on special shelves or racks, as, for example, it can be in lean-and gable greenhouses.

Shelving, hills and hanging racks are used to adjust cultivated plants, to place boxes and bowls with sowing and cuttings, etc.

Depending on the width of the greenhouse, along its length two stillages with a single canal in the middle or three stillages with two canals between them or four-five stillages are arranged.

Present greenhouses have demountable racks. Pipes of heating are placed closer to the stacks, and only part of the pipes is placed overhead in order to prevent freezing of windows in winter.

Racks are a deck on which you put the pots with plants. On the stillage you bulk a layer of sand about 3 cm thick, which is watered to always maintain moisture reserves under the pots with plants set on the racks. In cases when the stillages are applied for planting stems, a thin layer of ground is strewed under the sand.
