Without a greenhouse in the country can not do. In a hurry, the simplest "individual" greenhouse is made of a transparent plastic bottle with a cropped bottom.
Covering the plant, this simple design performs, meanwhile, all main functions greenhouse:
- Protects a sapling from external influences (cold, wind, rain, pests, etc.).
- Provides maximum sunlight access.
- Creates in the internal volume of a favorable temperature and high humidity.
- Easy access is provided for plant care.
Principle of operation
They all have a common design feature hidden under the ground.
Under the greenhouse, a trench is built, filled with biofuel - fallen leaves, mowed weeds and grass, branches that have accumulated after pruning fruit trees. A layer of fertile soil is poured on this green mass, and then a greenhouse is built on top.
The green mass, rotting away, generates heat that heats the ground and the air in the greenhouse.
After a year or two, the process is completed, and the biofuel is converted into humus.
To lay a new portion of green mass is required to dismantle the greenhouse and extract humus, which will serve to enrich the exhausted soil in the garden. Then set the greenhouse in place. He is ready to go again.
What are we growing?
The country greenhouse is intended primarily for growing seedlings of early seed vegetablesplanted in a warm ground protected from the external environment. Seeds in a greenhouse are planted in late winter or early spring.
Cucumbers and tomatoes, eggplants and cauliflower, sweet and hot peppers, zucchini and squash - all thermophilic vegetable crops will delight you with a harvest not a few weeks earlier.
But for seedling development in full fruitful plant will need much more space. The area of the mini-greenhouse is limited, and with the onset of warm weather in May, the grown-up seedlings will have to be transplanted to spacious garden beds.
The small height of the greenhouse limits the plants in growth. Previously, only many years of experience suggested exactly when the seeds should be planted, so that the plants would not stretch out under the greenhouse before the transplant.
Today there are dozens of online forums of gardeners and gardeners, where you can chat with your colleagues on hobby and get detailed advice.
Additional features
Mini-greenhouse will not stand idle after transplanting the first batch of seedlings. Whole season in him can grow all new and new cultures. For example, a radish in a greenhouse can produce two or three harvests (its growing season is 18-25 days). There is always room in the greenhouse. green onions, parsley and dill, spicy greens - mint, marjoram, thyme. Greenhouse remontant strawberry fruits from spring to late autumn.
A greenhouse creates all the conditions for rooting grapes, raspberries, currants, yoshty (agrus).
Glazing
There are a lot of materials for the walls of the mini-greenhouse: glass (with the exception of decorative color), plexiglass, transparent acrylic, polycarbonate (cellular or solid), PVC film.
Unlike flexible polycarbonate, bringing a large sheet of glass to the dacha for self-cutting is problematic, and you should be able to cut the glass. Much more rational order glass cutting under the desired size in the workshop.
Small glazing elements are easier to deliver. Need only pack them carefully. For this perfect straightened corrugated cardboard boxes. They are easy to get at the nearest grocery store. We shift the glass sheets with cardboard, then we tape them together. In one package we place no more than four or five sheets - heavy glass.
Glass and rigid monolithic transparent plastics limit the shape of the greenhouse to rectangular structures. Beautiful arched surfaces glazing allows you to create cellular polycarbonate and film.
Getting Started
Projects
Let's give the greenhouse one more function and make it an element of garden design.
Decorate the lawn nice greenhouse, resembling a transparent chest with a hinged lid. Rectangular walls can be made of glass (it is more durable than polycarbonate), the cover in the shape of a semi-arch - from cellular polycarbonate.
The frame is made of steel angle, it is more convenient to fix the glass in it. We will manufacture the arched cover structure from a rectangular thin-walled steel pipe.
For accurate pipe bending we make a pattern. On the brick wall we draw the line of the arch of the desired size. Along the line we drill holes and hammer in pointed steel cuttings with a step of 15-20 cm. Gradually bend the pipe using a template, using a lever from an armature rod. This job is easier to do with an assistant.
To prevent the pipe from deforming during bending, fill it with dry, sifted sand.
From the semi-walls and straight pipe segments we weld the frame of the lid, connect it to the frame from the corner with loops. On the frame we bend the sheet of cellular polycarbonate, fasten the part with self-tapping screws with wide washers. Polycarbonate is recommended to lay on any sealant.
Quite a bit of space will take a rectangular greenhouse near the sunny side of the fence. In this construction, the fence will serve as the rear wall of the greenhouse and support for hinges of the hinged cover.
If the fence is made of thin corrugated or mesh, the back wall will have to do. It is better to warm a brick or concrete fence in the greenhouse area with foam plastic or a slab of mineral wool, and sew it with plastic clapboard.
Conclusion
We hope our small article has convinced you that the mini-greenhouse in the country - the construction is extremely useful, and therefore necessary. It is not difficult to make it at all, materials will be needed a little.
Of course, entering into the taste of such growing seedlings, you will begin to think about building a more spacious greenhouse or a real greenhouse with heating. Look at the gardeners forums and specialized sites for a suitable project, create your own drawings, and go for building materials. You will succeed.
