There is no government subsidy. I believe that most growers still choose the type of vegetable greenhouse construction according to the principle of saving money.
Well, that's the simplest ordinary vegetable greenhouse. The overall construction cost of bamboo-wood structure is about 8000- 10000 yuan per mu per square meter 15 yuan. This greenhouse can be used for about three years, and the membrane is changed once every two years. The average annual cost is about 5000 yuan.
And now the galvanized steel pipe shed. The cost of this greenhouse is about 40 yuan per square meter, which is close to 300 million yuan per mu, and the service life of the main skeleton can reach 8 to 10 years. We choose to import po membrane and change it every three years.
The construction cost is about 4000 yuan per year;
Ok, that is, the construction cost of an ordinary vegetable greenhouse on an acre of land is 5000 yuan a year.
The land belongs to our own family, regardless of the cost. But as an analysis, we know that the rent of an acre of land in rural vegetable planting base is about 800- 1000 yuan. Let's just calculate according to the annual 800 yuan, then the rental cost of an acre of land is 800 yuan/year.
Labor cost, this problem is generally planted in rural areas, so it is temporarily ignored;
Fertilizer, pesticide, water and electricity, seeds and planting auxiliary materials in the process of vegetable planting will cost a lot according to different crops, so we take an average of 1500 yuan per year (which is cost-effective according to our own situation);
The above is an acre vegetable greenhouse, and the planting cost is about 5000+800+ 1500=7300 yuan.
Well, we have calculated the planting cost of an acre of land in a conventional vegetable greenhouse, so let's take a look at the planting output. We know that the advantage of vegetable greenhouse is that it can be planted out of season, such as early spring and late autumn. In this case, conventional vegetables are not available, and the price of the whole market is relatively high. Taking advantage of this off-season time difference, the benefits are often considerable. Tomato, eggplant, beans and sweet pepper are often selected as greenhouse vegetable crops in northern China. Planting cucumbers and other vegetables in great demand by the public. The seasonality of this vegetable is different from the annual market, but the average annual market price can reach one yuan to two yuan. Taking the median value of 1.5 yuan per catty, one acre of greenhouse vegetables can generally harvest about 5,000 kilograms of vegetables, and vegetable greenhouses can harvest vegetables in three to four seasons a year, which is about 20,000 kilograms of vegetables, about 1.5 yuan per catty.
In this way, it can be concluded that the profit of planting vegetables in greenhouse on an acre of land is about: 30000-7300=22500 yuan.
