Greenhouse Covering Film
1, thermal insulation, maintain temperature stability: the greenhouse film can effectively isolate the outside cold air, reduce heat loss, so as to keep the temperature in the greenhouse stable. This is essential for the growth of crops, and stable temperatures help promote the growth and development of plants. The role of double layer film: The double layer agricultural greenhouse covers two layers of film, and the thermal insulation performance is better than that of the single layer greenhouse. The coverage of two layers of film can further reduce heat loss and keep the temperature in the agricultural greenhouse constant, thus reducing energy consumption and reducing production costs.
2, adjust the light transmittance: the greenhouse film has a good light transmittance, can let most of the sunlight through, provide sufficient light for the plants in the greenhouse, which is essential for the photosynthesis of plants, help to improve the yield and quality of crops. Improve light intensity: In winter or in the case of insufficient sunlight, double-layer agricultural greenhouses can increase the light intensity in the greenhouse through reflection and refraction, further promoting the photosynthesis of plants.
3, reduce water evaporation, maintain soil water: greenhouse film can reduce soil water evaporation, maintain soil moisture, and prevent crops from poor growth or death due to water shortage. This is especially important in arid regions or greenhouses where water is scarce. Reduced watering frequency: Since film coverage reduces water evaporation, watering frequency can be reduced, thus saving water and labor.
4, prevent soil erosion, improve soil quality: agricultural greenhouse film can prevent rain directly erosion of soil, reduce soil erosion, protect soil fertility. Improve soil structure: film covering can also play a role in soil insulation, improve soil structure, enhance biological activity, promote microbial growth and organic matter decomposition, and thus play a certain regulatory role in regulating soil pH and improving soil quality.
5, reduce the modern greenhouse film coverage area, can reduce the occurrence of pests and diseases. Due to the formation of a relatively closed environment in the greenhouse, the invasion and transmission of external diseases and pests are reduced, thus reducing the occurrence of diseases and pests.
6. In summary,agricultural greenhouse film coverage plays an important role in maintaining temperature stability, regulating light, reducing water evaporation, preventing soil erosion, improving soil quality, and reducing pests and diseases. These effects jointly promote the growth and development of crops, improve the yield and quality of crops, and thus improve the planting efficiency. Therefore, greenhouse film covering is an essential means in modern greenhouse planting production.
