1.“培帕隆”是PC系列特殊地膜,由纤维质构成的多孔质性地膜。其突出特点是反光强、高强度、降温、透气、防虫。 (1) 不透雨水,可透过水蒸气(约15％),有通气性,可调节土壤中气体成分,防止CO~2积聚,增加含氧量。 (2) 降低地温效果突出,盛夏最高地温较黑白双面膜低4～10℃、较铝反射膜低2～5℃,较裸地低3～5℃,较地面敷草低1℃;最低地温,低于白黑膜及反射膜1～2℃,比裸地低1℃,是很理想的降低地温覆盖
1. “Pei Pai Long” is a special series of PC film, porous membrane composed of fiber. Its prominent feature is reflective, high strength, cooling, breathable, pest control. (1) impervious to the rain, through the steam (about 15%), breathable, adjustable gas composition in the soil, to prevent CO ~ 2 accumulation, increase oxygen content. (2) The effect of lowering ground temperature is prominent. The highest ground temperature in midsummer is 4 ~ 10 ℃ lower than that of black and white double-faced film, 2 ~ 5 ℃ lower than that of aluminum reflector, 3 ℃ ~ 5 ℃ lower than bare ground, , Lower than the white black film and reflective film 1 ~ 2 ℃, 1 ℃ lower than the bare, is ideal to reduce ground temperature cover
