1.北京塑料研究所最近研制成功能够阻隔紫外线的农膜,并具有降低棚内温度、耐老化的特点。夏季比一般大棚低2—3℃,波长380nm的近紫外线基本被阻隔住。是一种良好的西红柿等夏菜覆盖材料。2.该所还与塑料厂协作仿造成塑料遮阳网,重量轻、耐用、便于剪裁拼接,可用于各种经济作物的夏季降温覆盖。3.北京市试制成可以旋转喷水的塑料微型喷灌装
1. Beijing Institute of Plastics recently successfully developed to block the UV plastic sheeting, and have reduced greenhouse temperature, anti-aging features. Summer than the average greenhouse 2-3 ℃ lower, the wavelength of nearly 380nm near UV blocking. Is a good summer cabbage tomatoes and other materials covered. 2. The institute also collaborates with the plastic factory into a plastic shade net, which is light weight, durable and easy to be cut and spliced. It can be used for the summer cooling cover of various cash crops. 3. Beijing trial made into a spin-on plastic mini-sprinkler
