The greenhouse thermal insulation quilt has been continuously developed, from the initial straw felt to the various types of greenhouse thermal insulation quilts. The performance and function of the thermal insulation quilt are also continuously improved, and are used in the thermal insulation of solar greenhouses and agricultural greenhouses. Almost all greenhouse plantings will have greenhouse insulation quilts installed. When covering the greenhouse with thermal insulation quilts, make sure that the two beds of thermal insulation quilts are at least 10cm apart, and fasten the fixed nylon ropes to the fixing rods of the greenhouse. During the laying process, the curling deviation should be adjusted in time to ensure comprehensive coverage. After the greenhouse insulation is laid, use the link nylon rope to connect the insulation quilt as a whole. The greenhouse thermal insulation quilt is on the back wall of the greenhouse and should be fixed on the top of the wall, so that the top of the wall is inclined to the north, and covered with a complete tarpaulin to facilitate the discharge of rainwater and prevent the thermal insulation quilt from soaking. During the maintenance after covering, the accumulated water should be cleaned up in time to prevent it from being penetrated by water. In the event of wind and snow, the greenhouse should be loaded with thermal insulation and the snow should be cleaned up in time to prevent it from being blown by the strong wind, reducing the thermal insulation effect and crushing the greenhouse due to the excessive load on the roof. The difference in the cover form of the greenhouse insulation may lead to different use effects. Therefore, when choosing the cover form, we must choose the correct way to cover. 1. The greenhouse thermal insulation quilt can take the form of internal thermal insulation cover: This method is generally opened during the day and covered at night. It can also be used as a shading cover in high temperature weather. The way to adjust the temperature of the greenhouse generally adopts the manual type and the mechanical pull-and-release type. 2. The form of floating surface covering: the thin (20-30g/㎡) insulation quilt is directly covered on the open field or the border surface of the cultivation border in the facility, which plays the role of heat preservation, moisturizing, windproof and cold proof. 3. The form of external thermal insulation cover: the thermal insulation quilt is covered with the grass curtain on the slope of the greenhouse. When the greenhouse insulation quilt is in use, we need to pay attention to the relevant points and do a good job in maintenance, so as to ensure its performance and service life. 1. In the daily transportation process, the greenhouse insulation quilt should be handled with care, and it is strictly forbidden to drag it to avoid any harm. 2. In the rainy season, we should remove the greenhouse waterproof insulation quilt in time after it rains, and put it in a sunny and dry place for sun exposure, otherwise it will be easily soaked by rainwater, which is not conducive to the maintenance and maintenance of the insulation quilt. 3. When not in use, we should keep the greenhouse insulated in the sun and then roll it up for storage. Pay attention to store it in an open and dry place, and avoid prolonged exposure to sunlight. 4. After the greenhouse is covered with insulation, the snow and rainwater accumulated on the greenhouse should be cleaned up in time when it encounters rain and snow. In order to prolong the service life of the greenhouse insulation quilt. 5. If the greenhouse insulation is accidentally torn, it should be dried, stitched, rolled up and stored to avoid secondary damage to the tear in rain and snow.
