Dilution salt wash rice, is the northern Jiangsu coastal saline soil improvement and utilization of successful experience.But salt and rice after the transfer to dry farming, is different from the general arable land rotation and drought.If the conditions do not have, to avoid strong drought recovery, often In order to be able to better understand nature and transform nature, turning the free kingdom into an inevitable kingdom, so as to achieve the expected purpose of soil improvement and yield increase, we have once again failed to return to drought, From 1962 to 1965 and from 1971 to 1976, we conducted a survey on the utilization of salt and paddy rice for drought recovery, and summarized the relevant research materials as follows.
