盐碱地水稻育苗，适当使用硫酸亚铁会提高秧苗综合素质，使用硫酸亚铁的秧苗粗壮、颜色浓绿。ＰＨ 值７．５９ 左右、含盐量０．３７％ 、总碱度０．６９ｍ ｅ／１００ｇ 土的碱性碱土， 每３．５ｋｇ 碱性盐碱土使用８ｇ 左右硫酸亚铁（含量９５％ ） 为宜（以改善土壤营养状况为目的）， 每３．５ｋｇ 碱性盐碱土使用６０ｇ 硫酸亚铁 （含量９５％ ）， 会抑制秧苗正常生长。 Saline-alkali rice seedlings, the appropriate use of ferrous sulfate will improve the overall quality of seedlings, seedlings ferrous sulfate stout, dark green color. PH value of about 7.59, salt content of 0.37%, total alkalinity of 0.69m e / 100g soil alkaline alkaline earth per 3.5kg of alkaline saline alkaline use of about 8g ferrous sulfate (content 95%) of Suitable (to improve the nutritional status of the soil for the purpose of), per kg alkaline alkaline soil alkaline use 60g ferrous sulfate (content of 95%), will inhibit the normal growth of seedlings.
