一、地膜栽培的好处 1.提高地温,更有效地利用太阳能。2.保持土壤疏松状态,提高通透性能。3.促养分分解,保持较高肥力。4.防止干旱、涝渍,抑制杂草生长。5.可提早半个月成熟。二、辣椒对环境条件的要求 1.喜温适宜生长温度为28～30℃。苗期喜30℃左右。开花结果期白天喜21～26℃,夜间喜16～20℃;2.生长期间喜干燥空气和充足阳光;3.喜土壤湿润、空气相对 First, the benefits of plastic filming 1 to improve ground temperature, more efficient use of solar energy. 2. To keep the soil loose, improve permeability. 3. promote sub-decomposition, to maintain a higher fertility. 4. To prevent drought, waterlogging, inhibition of weed growth. 5 months earlier can be mature. Second, the environmental requirements of pepper 1. Xi Wen appropriate growth temperature of 28 ~ 30 ℃. Seedling hi about 30 ℃. Flowering fruiting day like 21 ~ 26 ℃, like night 16 ~ 20 ℃; 2. During the growth of hi dry air and plenty of sunshine; 3. Hi soil moist, air relative
