Generally, the skeleton of vegetable greenhouse needs about 5500 won per mu. In order to save the cost and prolong the service life of the greenhouse, the more economical way to build a plastic greenhouse is to use diamond-shaped greenhouse skeleton and plastic paper. This can not only reduce the construction cost, but also facilitate daily use and maintenance.
This greenhouse can be used for five years, and only plastic paper needs to be replaced every year. The cost of vegetable seedlings, pesticides and fertilizers per mu of land is about 700 won per year, and the land lease fee is about 800 won per year.
Combined with the above calculation, the initial investment of vegetable planting cost in plastic greenhouse is about 7000 yuan per mu, and the average annual cost sharing of vegetable greenhouse is about 2500 yuan per mu according to the five-year service life.
The profit of vegetable planting in plastic greenhouse is 150% ~ 250%, and vegetables can be produced for 2 ~ 3 seasons every year. If ordinary vegetables are planted, the cost of initial construction and vegetable management of plastic greenhouse can be basically recovered for vegetables in 1 ~ 2 seasons, and the income can be obtained in the first year, with an average profit of 100% ~ 150%. The annual fee for next year is to change plastic paper.
How to grow vegetables in plastic greenhouses-this is a very common question, but the answer is not simple. Vegetable cultivation technology in plastic greenhouse is a systematic technology. Many technical links in production should be mastered by vegetable farmers. To solve this problem, the only way is to accumulate the specific management knowledge of greenhouse vegetable planting technology one by one.
We will sort out all kinds of relevant materials, try to be easy to understand, and the materials will be improved in an orderly way, hoping to provide some help to your problem.
The construction cost of vegetable greenhouses is undoubtedly a concern of many vegetable farmers. 1. Understanding the types of vegetable greenhouses and the paving materials needed in the construction process will be of great help to the construction of vegetable greenhouses, thus saving costs and improving productivity.
Types and construction costs of vegetable greenhouses
6 meters wide assembled steel greenhouse. The warehouse is of steel membrane type, with galvanized thin-film steel pipe with a diameter of 22 mm and a thickness of 1.2 mm as the main shell skeleton material. The width of the membrane is 6m, the normal height is 2.2-2.5m, the shoulder height is1.2m, the land utilization rate is 80%, the service life is more than 10 years, and the area per square meter is10-Caicai, 30 yuan.
Simple bamboo shed. Widely used types, the shed type is generally 5-6 meters wide, the top is 2-3.2 meters high, the side is 1- 1.2 meters high, and the arch distance is1-1. Advantages are low construction cost, convenient interview and construction, and the cost per mu is about 3,000 yuan (smoke screen). The disadvantages are that there are many columns in the greenhouse, high shading rate, inconvenient work, short service life and poor snow resistance. Among them, there is a shed commonly known as "Erlangyong", which is 4 ~ 6 meters wide and has a high top and high shoulders. The method of covering one layer is more cost-effective than ordinary bamboo restaurants, and it is suitable for growing reptile crops. Watermelon in plastic greenhouse is widely used. Steel-bamboo hybrid greenhouse. The scaffolding structure is the same as the simple bamboo scaffolding, and the spacing is arched by steel pipes and bamboo poles, which saves steel, reduces cost, is convenient to operate and has a certain application area. Performance and cost are between steel frame house and bamboo shed.
8-meter-wide greenhouse with protruding steel frame. Increase the height and width of the warehouse, improve the height and width of the ventilation window at the warehouse side, increase the space in the warehouse, improve the management efficiency and warmth in winter, and improve the land utilization rate. The warehouse adopts galvanized pipes with a diameter of 28-32 mm and a thickness of 1.5 mm, with a normal height of 3.2-3.5 m, a shoulder height of 1.8 m and a large membrane space, which is suitable for planting thousands of vegetables. However, the construction cost of vegetable houses has risen sharply, about 20-45 won per square meter and 0/.5-30,000 won per mu/kloc, which is mainly suitable for agricultural demonstration parks and vegetable farmers with certain economic strength.
Ordinary multi-storey greenhouse and simple bamboo multi-storey greenhouse. Generally, the multi-room structure is similar to the steel frame house, with large space and high land utilization rate, but the cost is lower, 50 ~ 100 yuan per square meter.
