土壤酸化的原因①日光温室蔬菜产量高,从土壤中带走了过多的碱基元素,如钙、镁、钾等,导致了土壤中的钾和中微量元素消耗过度,使土壤向酸化方向发展。②大量生理酸性肥料,如硝酸铵、硫酸铵的施用,温室温、湿度高,雨水淋溶作用少,随着栽培年限的增加,耕层土壤酸根积累严重,导致了土壤的酸化。③由于日光温室复种指数高,肥料用
Soil acidification ① solar greenhouse vegetable yield is high, took away from the soil too much alkali elements, such as calcium, magnesium, potassium, led to soil potassium and trace elements in the excessive consumption of the soil to the acidification direction development of. ② A large number of physiological acid fertilizers, such as ammonium nitrate, ammonium sulfate application, greenhouse temperature and humidity, rainfall leaching less, with the increase of the cultivation period, tillage soil acid accumulation is serious, resulting in soil acidification. ③ due to solar greenhouse multiple crop index, fertilizer use
