The spring and autumn cold shed, also known as the simple arched shed, is a simple and practical protected cultivation facility. The following is a detailed introduction to it:

Structural characteristics

1. Frame material: Steel frame materials such as hot-dip galvanized steel pipes are mostly used, which are sturdy, durable and easy to install. Some customers have special requirements for galvanized steel frame structures, and some use elliptical tubes and several-shaped steel to make the skeleton to enhance strength.

2. Covering material: The top is usually covered with polyethylene anti-drip long-life film. The outer layer is UV-resistant and the inner layer is anti-drip. This can effectively extend the service life of the film, increase the light transmittance, and provide good light conditions for crop growth. The four sides can be covered with polyethylene non-drip long-lasting film or polycarbonate hollow board according to the user's needs.

3. Specifications and dimensions: The span is generally 8 meters and the height is 3 meters. According to the dimensional differences in span and ridge height, they can be classified into small spring and autumn sheds, medium spring and autumn sheds and large spring and autumn sheds. According to the different shapes of the sheds, they can be classified into floor-standing spring and autumn sheds, vertical side wall spring and autumn sheds and inclined side wall spring and autumn sheds. Among them, the inclined side wall spring and autumn shed is the most widely used type at present. We can also design and manufacture according to the requirements of customers.

Performance advantage

1. Low cost: The structure is simple, with low material costs and construction expenses. It is an economical greenhouse and suitable for a wide range of farmers and agricultural producers to use.

2. Easy installation: Mostly designed as a single building, the installation process is relatively simple, without the need for complex construction techniques and equipment. It can be quickly set up and put into use.

3. Good heat preservation and ventilation: During the nights of spring and autumn, it can effectively keep the temperature inside the greenhouse higher than that outside, preventing crops from being damaged by low temperatures. When the temperature rises during the day, ventilation can be carried out through the manually rolled film ventilation Windows reserved on both sides to regulate the temperature inside the greenhouse and prevent overheating.

4. . Resistance to natural disasters: To a certain extent, it can defend against natural disasters such as wind, rain and frost, providing a relatively stable environment for crop growth and reducing the impact of natural disasters on crops.

Applicable crops

1. Spring planting: It is suitable for growing early spring crops such as tomatoes, cucumbers, peppers, eggplants, zucchini and melons. Generally, seedlings are raised in February to March and transplanted in March to April. Spinach, Chinese cabbage, lettuce, crowndaisy chrysanthemum and other leafy vegetables are also suitable. These leafy vegetables can tolerate low temperatures and have a short growth cycle.

2. Autumn planting: Autumn delayed crops such as Chinese cabbage, radish, cabbage, cauliflower and celery can be planted. They are usually sown in July and August and harvested from September to November. There are also autumn harvest tomatoes, cucumbers and other fruits and vegetables, but it is necessary to pay attention to keeping them warm and protecting them from the cold.

Application scope

1. Vegetable cultivation: Mainly used for early spring and late autumn vegetable production, ensuring the supply of vegetables during the off-seasons of spring and autumn, and increasing farmers' income. Meanwhile, it can also be used for shading and seedling raising of vegetables in early spring and summer.

2. Seedling cultivation of fruits, vegetables and flowers: Provide a suitable seedling environment for fruits, vegetables and flowers, increase the survival rate and quality of seedlings, cultivate healthy seedlings, and lay a good foundation for subsequent growth and production.

3. Leisure Picking: It can be used to grow various fruits and vegetables suitable for picking, such as strawberries, grapes, cherries, etc., to create a leisure picking garden, attract tourists to come for picking, increase the added value of agriculture, and develop sightseeing agriculture and rural tourism.
