Profit and cost of vegetables in greenhouse

The cost and profit of vegetable cultivation in greenhouse are mainly determined by the agricultural materials needed for the construction and maintenance of greenhouse and the management of vegetable cultivation. The situation will be different from place to place. Let's take a look at the profit analysis of vegetables in the greenhouse.

Profit and cost of 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, which reduces the construction cost and is 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.

How to grow vegetables in greenhouse? This is a very common question, but the answer is not simple. Greenhouse vegetable planting technology is a systematic technology, and many technical links in production need to be mastered by vegetable farmers. If you want to solve this problem, the only way is to accumulate specific management knowledge of greenhouse vegetable planting techniques one by one. We have combed a wide range of related materials, and strive to be easy to understand, and the materials will be added and improved step by step, hoping to provide some help to your questions. The construction cost of vegetable greenhouse is undoubtedly an issue of great concern to vegetable farmers. To understand the types of vegetable greenhouse and the bedding materials needed in the construction process will be of great help to the construction of vegetable greenhouse, so as to save money for you and improve production efficiency.

Types and construction cost of vegetable greenhouse

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 pipe with a diameter of 22mm and a thickness of 1.2mm as the skeleton material of the shed. The width of the shed is 6m, the top height is 2.2m, the shoulder height is 1.2m, the land utilization rate is 80%, and the service life is more than 10 years. The cost is 10-30 yuan per square meter, and the construction cost is 7000-20000 yuan per mu. 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 frame greenhouse. Is a widely used type, the shed type is generally 5-6 meters wide, the top height is 2-3.2 meters, the side height is 1-1.2 meters, and the arch spacing is 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 and bamboo mixed greenhouse. The shed structure is the same as the simple bamboo frame greenhouse, and the steel pipe and bamboo pole are used as arch bars at intervals, which has the advantages of saving steel, reducing cost and convenient operation, and has a certain application area; the performance and cost are between steel frame greenhouse and bamboo frame greenhouse.

4, 8 meters wide to improve the section steel frame greenhouse. It increases the height and width of the shed, increases the height and width of the ventilation window on the side of the shed, increases the space in the shed, improves the management efficiency and winter insulation, and improves 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 the ordinary multi-span greenhouse is similar to that of the 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 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.
