摘要
研究江苏垦区种植洗盐添加化学改良剂加速脱盐效果,结果表明:添加化学改良剂能加速土壤脱盐,3种化学改良剂对土壤盐分的改良效果与对照比较均较显著,土壤盐分平均多降10%,其中以施地佳效果最好,比空白处理多降13.48%,水稻产量增加813.6kg/hm2。
Accelerating desalting effect on drenching salt by planting rice added chemical improvement agent in Jiangsu reclamation area was studied.The results showed that added chemical improvement could accelerate soil desalting.Three improvement effect of chemical amendments on soil salt content compared with control were significant,the soil salinity average dropped 10 percent,of which the best effects of Shidijia,down 13.48 percent more compared with the blank treatment,rice yield increased 813.6 kg/hm^2.
