1.稀土转光农膜该农膜是在高压聚乙烯中加入稀土螯合物(转光添加剂)吹制而成。与普通农膜相比,该膜能将日光中的紫外线转换成红橙光,从而使温室或大棚内植物光合作用强度提高88%,寒冷季节棚温提高1～5℃、地温提高1～3℃,作物成熟提早7～15天,产量提高15%～35%。另外,该膜还具
1. Rare-earth light-emitting plastic film The plastic film is a high-pressure polyethylene by adding rare earth chelate (light transfer additives) blowing system. Compared with ordinary agricultural film, the film can convert the ultraviolet light in sunlight into red-orange light, so that the photosynthesis intensity in plants in greenhouse or greenhouse can be increased by 88%, the shed temperature can be increased by 1-5 ℃ in cold season and the temperature can be increased by 1-3 ℃, crop maturity 7 to 15 days earlier, the yield increased by 15% to 35%. In addition, the film also has
