The amount of pesticide and herbcide applied was less, the pure quantity was only 1. 9kg/ha which is about 40％ of the Jinlin Province's average. In farmland, There are 26700ha of solonetz and solonchak, and 289700ha of salinized soil with the high content of salts. The salt content in the surface is 1％-2％ in soda meadow solonetz, 1％-4％ in sulfate meadow solonetz, below 0.7％ in meadow solonchak generally, and below 1％ in salinized soil. The runoff and the return flow from above lands have high content of salt and high output load of the soluble salt.
