Profit from growing vegetables in greenhouse

The cost and profit of vegetable cultivation in greenhouse are mainly determined by the construction and maintenance of greenhouse, as well as the agricultural materials needed for vegetable planting management, and the situation will be different in different places. The following is the analysis of the profits of vegetable cultivation in greenhouse under conventional circumstances.

Profit from growing vegetables in greenhouse

Generally speaking, the vegetable greenhouse skeleton per mu needs about 5500 yuan. In order to save the cost and prolong the use time of the greenhouse, a more economical way to build the greenhouse is to use magnesite greenhouse skeleton and plastic paper, so as to reduce the construction cost. It is also convenient for daily use and maintenance. Such a greenhouse can be used for five years, and only need to change the plastic sheet every year. The annual cost of vegetable seedlings, pesticides and fertilizers per mu is about 700 yuan, and the annual land rental fee is about 800 yuan.

Combined with the above calculation, the vegetable planting cost in the greenhouse is about 7000 yuan per mu of initial investment, and the average annual sharing cost of each mu of land is about 2500 yuan with a five-year use life of the vegetable greenhouse.

The profit of growing vegetables in the greenhouse can reach 150%, 250%, and can produce 2-3 seasons of vegetables every year. If you grow ordinary vegetables, the vegetables of 1-2 seasons can basically recover the initial construction and greenhouse vegetable management costs. In this way, you can make a profit in the first year, with an average profit of 100%. The average profit is 150%. The annual cost in the following years is to change some plastic paper.

Types of vegetable growing greenhouses

1, 6 meters wide prefabricated steel frame greenhouse: this type of shed has been popularized and applied for many years. It is mainly made of galvanized thin-walled steel pipes with a diameter of 22mm and a thickness of 1.2mm as the skeleton material of the shed. The shed is 6 meters wide, the top height is 2.2m, the shoulder height is 1.2m, the land utilization rate is 80%, the service life is more than 10 years, the cost per square meter is 10-30 yuan, and the construction cost per mu is 7000-20000 yuan. It is suitable for growing vegetables and flowers, but its disadvantages are small shed width, low efficiency of operation and management, and weak thermal insulation in winter.

2. Simple bamboo shed: it is a widely used type, with a width of 5-6 meters, a top height of 2-3.2 meters, a side height of 1-1.2 meters, and an arch spacing of 1-1.1 meters. The advantages are low cost, convenient material acquisition and easy construction, and the cost per mu is about 3000 yuan (even film). The disadvantage is that there are many columns in the greenhouse, high shading rate, inconvenient operation, short service life and poor resistance to wind and snow. Among them, there is a kind of greenhouse type commonly known as "ground roll dragon", with a span of 4-6 meters, top height to shoulder height, using a film to cover the end, which is more cost-saving than ordinary bamboo and vegetable greenhouse, and is suitable for climbing crop cultivation, and watermelon cultivation in greenhouse is widely used.

3. Steel-bamboo mixed greenhouse: the structure of the greenhouse is the same as that of the simple bamboo greenhouse, and the steel pipe and bamboo pole are used as arch bars at intervals, which has the advantages of saving steel, reducing cost, convenient operation and so on, and has a certain application area; the performance and cost are between steel greenhouse and bamboo greenhouse.

4, 8 meters wide to improve the section steel frame greenhouse: increase the height and width of the shed body, increase the height and width of the ventilation window on the side of the shed, increase the space in the shed, improve the management efficiency and winter insulation, and improve the land utilization rate. The shed is made of galvanized tubes with a diameter of 28-32 mm and a thickness of 1.5 mm, with a top height of 3.2-3.5 meters and a shoulder height of 1.8 meters. However, the construction cost of this vegetable greenhouse is greatly increased, with a cost of about 20-45 yuan per square meter and 1.5-30,000 yuan per mu, which is mainly suitable for agricultural demonstration parks and vegetable farmers with certain economic strength.

5. Ordinary multi-span greenhouse and simple bamboo frame multi-span greenhouse: the structure of ordinary multi-span greenhouse is similar to that of steel frame multi-span greenhouse, which has the advantages of large space and high land utilization rate, but the cost is greatly reduced, 50-100 yuan per square meter.

Mulching material for vegetable growing greenhouse

Vegetable farmers should choose suitable vegetable greenhouse covering materials according to their own production needs.

1. Ordinary film: with polyethylene or PVC as raw material, the greenhouse film is 0.1 mm thick, colorless and transparent, and the service life is about half a year.

2. Multi-functional longevity film: made by adding appropriate amount of anti-aging material and surfactant in the process of polyethylene blow molding. The width is 7.5m and the thickness is 0.06mm. The service life of the film is twice as long as that of the ordinary film, and the greenhouse temperature at night is 1-2 ℃ higher than that of other materials. The film is not easy to form water droplets, good covering effect, low cost and high benefit.

3, straw quilt, straw fan: made of straw, good thermal insulation performance, is a night thermal insulation material.

4. Polyethylene high foaming film: White bubbly plastic film, 1 meter wide and 0.4-0.5 cm thick, light and can be rolled up, and its thermal insulation is similar to that of grass quilt.

5. Non-woven fabric: a kind of polyester filament, unwoven cloth. It is divided into black and white, and has different density and thickness. it can also be used as a sunshade net in addition to heat preservation.

6. Sunshade net: a kind of plastic wire mesh. Commonly used are black and silver gray, and there are several density specifications, shading rates are different. It is mainly used for sunshade and rain protection in summer, and can also be used as thermal insulation cover in winter.

Orientation of vegetable planting greenhouse

It should be built on the land with low groundwater level, sufficient water source, convenient drainage and irrigation, loose, fertile and pollution-free soil; generally, the seat direction is north-south, and the air outlet is located on both sides of the east and west.

The main results are as follows: 1. it is beneficial to the decrease of humidity in the shed.

2. The mutual shading between cultivated crops and tall crops in the greenhouse is reduced, so that they receive light evenly.

3. It avoids the excessive cooling and the invasion of the north wind during the ventilation (cooling) and ventilation operation of the greenhouse in winter, and increases the ventilation capacity at the same time.

Well, the editor of the profit analysis of vegetable planting in greenhouse ends here. The development of vegetable planting technology in greenhouse can be said to be a trend. With the improvement of people's living standards, the demand for the diversification of vegetables will further increase. Vegetable greenhouse can make up for the seasonal deficiency of some vegetables, which will undoubtedly play an important role in vegetable production in the future.
