摘要
含铜酸性废水污染的农田,土壤呈酸性,有效铜含量较多,严重影响水稻的生长发育,导致减产.投加石灰、有机肥料和硫磺等,都能促进作物生长,产量成倍增加。其中以施用石灰后,再用少量硫磺沾秧根效果最佳,可在当地推广应用.
The farmland polluted by acidic copper-bearing water has a very highavailable-copper content.The acidity and copper content seriously affectthe growth of rice,and lead to a reduction of rice production.Adding lime,manure and sulphur etc.to the soil promoted the growth of rice anddoubled the yield.Especially,applying lime and a little sulphur at the rootof rice seedlings produced the best effect.This method can be extended inthe local area.
