What is light-converting plastic sheeting for greenhouse?
Light-converting plastic sheeting is a functional agricultural film developed based on the properties of rare earth elements. It is mainly used in protected agriculture (such as greenhouses and sheds). By regulating the spectral distribution of sunlight, it optimizes the plant growth environment, thereby improving crop yield and quality.
The key to rare earth light-converting plastic sheeting lies in the rare earth light converters added to them (usually organic or inorganic compounds of rare earth elements, such as complexes of europium, terbium, neodymium, etc.). Such substances can absorb parts of the solar spectrum that have weak effects on plant growth (e.g., ultraviolet light and part of green light) and convert them into red-orange light or blue-violet light, which are most needed for plant photosynthesis (plant chlorophyll mainly absorbs light in these two wavelength bands for photosynthesis).
Advantages of light-converting plastic sheeting
| Advantage | Description |
|---|---|
| Improved Light Utilization Efficiency | High light conversion efficiency: it can convert green light, ultraviolet light, and other light that plants absorb less into red-orange light and blue-violet light needed for photosynthesis. The ultraviolet conversion rate reaches 98.1%, and the photosynthetic rate increases by more than 20%, significantly improving the effective use of sunlight. |
| Optimized Crop Growth | Vegetables grow robustly, with developed root systems, sturdy stems, dark green leaves, and overall good growth. It also promotes early maturity of crops, with the ripening time advanced by about 5-20 days (among which solanaceous vegetables are generally ready for picking 5-14 days earlier). |
| Enhanced Crop Yield and Quality | It has significant high-yield and early-maturing characteristics. The yield of general crops increases by 20-30%, and that of solanaceous vegetables can reach 30-50%. It also promotes the accumulation of nutrients, improving crop quality. |
| Strengthened Stress Resistance and Ecological Performance | Effectively controls diseases and pests, reducing pesticide usage; reasonably regulates the internal environment of greenhouses, increasing temperature and reducing humidity, which is more conducive to crop growth; safe and reliable, meeting the needs of green planting. |
| Wide Application Scenarios | Suitable for protected agriculture such as greenhouses and sheds, with remarkable effects on vegetables, fruits, flowers, and other crops, especially in areas with insufficient light. |
| Excellent Economy | Economically affordable, with a cost equivalent to that of ordinary PO films; some products have strong aging resistance and weather resistance, with a long service life, which can reduce the cost of frequent film replacement. |
