Vegetable soilless culture in the first few years is still a new research and development of planting technology, now it has been widely used, vegetable soilless culture refers to the use of soil without the use of other substances as a source of nutrients and fixation of plants, or only in the nursery when the use of substrates, planting the use of nutrient solution for irrigation after a kind of cultivation mode.

Vegetable soilless culture also needs to be carried out in vegetable soilless culture greenhouse, so the construction of vegetable soilless culture greenhouse is very important, today Xinhua greenhouse editor will talk to you about this vegetable soilless culture greenhouse.

Want to know an acre of vegetable greenhouse planting profits, necessarily have to know the cost of the problem first, since the consultation to planting profits, we do not talk about what subsidies and so on, that is not what you get from planting.

No government subsidies, I believe that most growers are still in accordance with the principle of construction can save to choose the type of construction of vegetable greenhouses. Well, that's the simple ordinary vegetable greenhouse, the overall construction cost of bamboo and wood structure of about 15 yuan per square meter, that is, 8,000-10,000 yuan an acre.

This kind of shed can be used for about three years or so, the membrane two years a change, on average, the annual cost of about 5000 yuan; there is also a contemporary galvanized steel pipe shed, this kind of shed cost per square in about 40 yuan, that is, close to 30,000,000 yuan per acre, the service life of the main skeleton can be up to 8 to ten years, choose to import po film, three years a change.

Construction cost it, about 4,000 yuan per year, right; well, that is, an acre of ordinary vegetable greenhouse construction cost is 5,000 yuan a year.

One acre of greenhouse vegetables can generally harvest about 5,000 pounds of vegetables, vegetable greenhouses can be harvested in three to four seasons a year routine vegetables, that is, about nearly 20,000 pounds of vegetables, according to the 1.5 yuan per catty, about 30,000 yuan in profit. This kind of theoretical calculations can be derived from an acre of vegetable greenhouse planting profit is about: 30,000-7300=22,500 yuan.

The land is their own family, we can not consider the cost, but as an analysis, we know that the current rural general vegetable planting base is now about 800-1000 yuan per acre of rent between, let's just count 800 yuan per year, this way is the cost of rent per acre of land is 800 yuan / year.

Labor costs, this issue is generally in the rural areas are planted, so we ignore;

Vegetable planting process of fertilizers, pesticides, water and electricity, seeds and planting of auxiliary materials, according to the planting of different crops, the cost will also be larger, let's just take an average of 1,500 yuan per year (according to their own situation specific calculations).

The above is an acre of vegetable greenhouse planting cost is about 5000+800+1500=7300 yuan. Well, calculated the acre of conventional vegetable greenhouse planting costs to come, we will look at the planting output: we know that the advantage of vegetable greenhouses is that vegetables can be planted in the anti-season, early spring and late fall planting, in this case conventional vegetables are not available, the entire market price is relatively high, the use of this anti-seasonal time difference, the benefits are often considerable, the northern region of the greenhouse vegetable crops are often selected tomatoes, eggplants, beans, sweet peppers and other vegetables. Eggplant, beans, sweet peppers, cucumbers and other popular demand for high vegetables for planting.
