The invention forms a new soil layer structure with the upper part rough and the lower part fine, increases a coarse sand content of upper soil and obviously improves soil tilth; thereby facilitating the leaching of the salt. Only half a year is needed and then the salt content of a plow layer is reduced from six point five four gram per kilogram to one point two three gram per kilogram; thereby speeding up the improvement and utilization speed of the marine solonchak and restraining the uprise of salt.

本发明形成上粗下细的新土层结构，增加了上层土壤的粗砂粒含量，明显改善了土壤耕性；有利于盐分的淋洗，仅需半年时间，耕作层含盐量即可由6.54g/kg降至1.23g/kg，加快了滨海盐土的改良利用速度，并抑制了返盐现象。
