The cotton quilt greenhouse is a common agricultural facility. It is covered with cotton quilts on the outer layer of the greenhouse film, which can effectively reduce the heat loss of the greenhouse. In the cold winter, it can increase the temperature inside the greenhouse by 5-10 ℃ compared with when the insulation quilt is not used, providing a suitable temperature environment for crop growth, which is conducive to the safe overwintering of crops and increases crop yield and quality.

Working principle

Lighting and temperature increase: The front roof of the greenhouse is covered with plastic film with good light transmission, allowing sunlight to fully penetrate into the greenhouse. Solar radiation energy is absorbed by the ground, walls, crops and other parts inside the greenhouse and converted into heat energy, raising the temperature inside the greenhouse.

Thermal insulation and heat storage: The walls and the rear roof have excellent thermal insulation performance, which can reduce heat loss. Meanwhile, they can also absorb and store solar radiation energy during the day and release it slowly at night to maintain the temperature inside the greenhouse. The cotton quilt covering the plastic film further enhances the insulation effect of the greenhouse and reduces the heat dissipation outward.

Composition

It is composed of multiple different materials, generally including a waterproof layer, an insulation layer, an anti-aging layer, etc. For instance, the outer layer can be made of waterproof and anti-aging plastic film or non-woven fabric, the middle layer can be made of materials with good heat preservation performance such as fiber cotton or polyester fiber, and the inner layer can be made of soft cotton cloth, etc., to protect the greenhouse film. This kind of thermal insulation blanket has relatively good comprehensive performance, with excellent heat preservation, waterproofing and durability, but its price is relatively high.

Advantages

1) Good heat preservation performance: The covering of cotton quilts effectively reduces heat loss, keeping the temperature inside the greenhouse relatively stable on cold nights, providing a suitable growth environment for crops, and is conducive to the growth of winter vegetables and other crops.

2) Low cost: Compared with some modern intelligent greenhouses, the construction cost and operation cost of quilt greenhouses are relatively low. Its structure is simple, the materials are easy to obtain, and it does not require complex equipment and technical support. It is suitable for use by a wide range of farmers and small-scale agricultural producers.

3) Easy operation: The covering and uncovering of the quilt are relatively simple, and farmers can flexibly control it according to the weather conditions and the growth needs of their crops. Meanwhile, the ventilation, irrigation and other facilities of the greenhouse are also relatively easy to operate and manage.

Application

Greenhouse cotton quilts are widely used in various types of agricultural facilities such as vegetable greenhouses, flower greenhouses, and fruit planting greenhouses. Whether it is the overwintering greenhouse in the cold northern regions or the greenhouses used for off-season planting in the south, greenhouse insulation quilts can be used to increase the temperature inside the greenhouse, create a favorable environment for crop growth, and achieve continuous production throughout the year. Meet the market demand for fresh agricultural products.
