What are the latest requirements for vegetable greenhouse construction?

Planting vegetables in greenhouses has many advantages, mainly that it allows off-season cultivation and four-season cultivation, so many people choose to use greenhouses to grow vegetables. But how should a greenhouse for growing vegetables be built, what should it be set up like, how can it bring more benefits, and what are the construction requirements? Here is an introduction to some of the better setups.

1. Choosing the land

The land for building a greenhouse needs to be a sufficiently spacious, large flat plot. Uneven ground, or hillside plots that are not large enough, cannot be used. If built in fields at the foot of a mountain, areas prone to summer flooding cannot be used, because drainage is inconvenient and water easily accumulates. It is best to build on land with a certain elevation that also has a water source. This makes management more convenient. Choose a direction facing the sun.

2. Structural materials

Currently, the common simple bamboo structure is the cheapest, easy to disassemble, relatively low in cost, and good for light transmission, but it has poor functionality and does not withstand wear. There is also the concrete pillar structure; this kind of frame is relatively bulky, blocks more light, is not easily damaged, can last several years, and is medium-priced, making it a common and widespread choice. The steel structure is the lightest and of the best quality, but its relative cost is somewhat higher, and its effect is the best. You can choose it, or go to the market to find out whether there are new material options.

3. Construction types

A simple greenhouse is a simple arched greenhouse with edges directly pressed down with soil and doors at both ends. A sunlight greenhouse has a relatively high frame space, and its plastic film covering has very good light transmission. Most are steel structures, built as a greenhouse with the lower half upright and square and the upper half arched; the materials are different. Some also have sprinkler and insulation facilities. Outside there is also straw matting for insulation, and inside there are straw curtains for moisture retention. Drainage channels are set up.

4. Preparing facilities

The greenhouse film must be able to be rolled up, and manual film-rolling or automatic film-rolling facilities must be installed. There must be supporting steel wire ropes to resist strong winds, as well as the necessary facilities for irrigation, fertilizing, drainage, and transport. The greenhouse film must have good light transmission and receive light well. Skylights must be installed. Install complete facilities for ventilation and light transmission, and facilities for air exchange and disinfection. In this way it is relatively complete.

For vegetable-growing greenhouses, the main things are to choose a site that does not accumulate water and faces the sun, and to choose greenhouse materials and construction forms within what you can afford. You must prepare all kinds of facilities that will be used, to ensure a good environment for vegetable cultivation.
