How much does it cost to build a greenhouse? A detailed breakdown of greenhouse construction costs

Greenhouses were originally specialized equipment for vegetable production. With the development of production, greenhouses have become increasingly widely used. At present, greenhouses are already used for potted flower and cut flower cultivation, fruit tree cultivation, forest tree seedling raising, ornamental tree cultivation, silkworm rearing, chicken farming, cattle farming, pig farming, fish and fry, etc. Let's take a look below at how much it costs to build a greenhouse!

Steel pipe greenhouse arched shed

[Cost] The cost of a steel pipe greenhouse is about 20-45 yuan per sq m.

[Specifications] The span of a steel pipe greenhouse is generally 8-14 m. The frame is entirely assembled and welded from hot-dip galvanized steel pipes or rectangular pipes. Both sides of the greenhouse are equipped with manual film roll-up devices and insect-proof nets.

[Advantages] The steel pipe greenhouse has a relatively low cost, uses an integral frame structure with high strength, and has a relatively high land utilization rate.

[Disadvantages] Its heat preservation and heat storage capacity is relatively weak, and it cannot meet the needs of winter production. It is suitable for spring and autumn cultivation of vegetables, fruits, flowers, and edible fungi.

Simple multi-span arched shed

[Cost] The cost of a simple multi-span arched shed is about 100 yuan per sq m, and it is suitable for spring and autumn cultivation of high-value vegetables, flowers, medicinal materials, edible fungi, etc.

[Specifications] The frame of the simple multi-span arched shed uses hot-dip galvanized rectangular pipes or round pipes, with gutters at the top and ventilation windows at the ends, the same as the basic structure of an arched shed.

[Advantages] The simple multi-span arched shed has a relatively large interior space, is suitable for large-scale factory-style operations, and has a high land utilization rate.

[Disadvantages] The simple multi-span arched shed has a relatively high cost, low cooling efficiency in summer, and high drainage requirements.

Earth wall solar greenhouse

[Cost] The cost of an earth wall solar greenhouse is about 750-850 yuan per sq m. The cost is lower with a non-all-steel frame, making it very suitable for off-season cultivation of high-value crops such as vegetables.

[Specifications] The span of an earth wall solar greenhouse is generally 10-15 m. The wall structure is built by repeatedly rolling and compacting earth. It is generally covered with 10-silk to 15-silk double anti-drip film. The shed surface frame currently mostly adopts an all-steel welded structure. The insulation material generally uses greenhouse insulation quilts of 4-6 jin per sq m, and a roll-up machine is used to pull and release the insulation quilts.

[Advantages] The advantages of an earth wall solar greenhouse are relatively low cost, relatively good insulation and heat storage effect in winter, and relatively low later-stage use and maintenance costs.

[Disadvantages] The earth wall solar greenhouse has a relatively large wall footprint, which affects the net planting area of the greenhouse, and it has certain requirements for soil quality. If protective measures are not taken well for the wall, it is easily eroded by rain and snow, affecting its service life.

Brick wall solar greenhouse

[Cost] The cost of a brick wall solar greenhouse is 1600-1700 yuan per m. Among this, the cost of the greenhouse wall is about 1000 yuan per sq m, and the cost of shed surface materials such as the shed surface frame is about 600-700 yuan. It is suitable for cultivation of vegetables, edible fungi, flowers, fruit trees, etc.

[Specifications] The span of a brick wall solar greenhouse is 8-15 m. Its wall structure is built with red bricks or concrete foamed bricks, and the wall thickness is generally 0.37-1 m. The other structures are basically the same as those of an earth wall solar greenhouse, all composed of an all-steel frame, covering film, insulation cotton quilts, and a roll-up mechanism. If several types of steel frames are used as shed surface supports, the cost per m of the greenhouse can be further reduced. Among this, the cost of the brick wall is about 1000 yuan per m, and using concrete foamed bricks can reduce the greenhouse cost by 100-150 yuan per m.

[Advantages] The brick wall solar greenhouse has a sturdy and durable structure, and its service life can reach 20-25 years. The brick wall solar greenhouse has a relatively high land utilization rate and strong regional applicability, and is especially suitable for construction and use in areas with complex geology, low water levels, and where earth walls cannot be built.

[Disadvantages] Because the brick wall solar greenhouse uses a brick wall structure, its cost is higher than that of an earth wall solar greenhouse, and the investment payback period is relatively long.

New-type solar greenhouse

[Cost] The cost of a new-type solar greenhouse is 1000-1200 yuan per m. It is actually upgraded from an earth wall solar greenhouse, and is suitable for high-value-added industries such as scientific research experiments, breeding and seedling raising, and exhibitions.

[Specifications] The overall structure of the new-type solar greenhouse is consistent with that of a traditional solar greenhouse, and the span can reach more than 15 m. The wall part is built with earth walls and then reinforced with cement mortar. The greenhouse frame is made of hot-dip galvanized rectangular pipes plus spring clips and clip grooves, and the rest is the same as an earth wall solar greenhouse.

[Advantages] The wall of the new-type solar greenhouse is reinforced with cement mortar, which reduces the risk of wall collapse of the earth wall solar greenhouse, and increases durability and service life by more than 5-10 years. The shed surface film is fixed with spring clips and clip grooves, making it more convenient to replace the film later. The large span and large space allow the configuration of advanced equipment such as mobile seedbeds and mobile sprinkler irrigation.

[Disadvantages] The new-type solar greenhouse has a relatively large wall footprint and a relatively high greenhouse cost, which reduces the cost-effectiveness of the solar greenhouse and makes promotion and popularization relatively difficult.
