Agent, and preparation method is further disclosed.
Background technique
So-called salt affected soil refers to arid or semiarid low-lying district more, under conditions of the dynamics of evaporation is strong, level of ground water is high,
Soluble organic fraction rises with soil capillary, accumulates excessive salinity in the soil body especially upper soll layer and a kind of soil class for being formed
Type.Salt-soda soil due to salt aggregation, inside soil contained by salinity influence the normal growth of crop.Wherein, because by gas
The effect of natural conditions such as time, landform, soil texture and the salinization of soil or the soil salinization formed, soil of being known as are primary
Salinization of soil or primary salination;And as caused by the various inappropriate land development behaviors of the mankind and development activities originally not
Salinization of soil or salination has occurred in salinization of soil or saliferous soil, enhance that soil is original saline and alkaline or degree of salinity then at
For this life salinization of soil of soil or this life salination.
The salinization of soil is a global problem, and whole world salinized soil area is 1,000,000,000 hectares about nearly, and China has 9913
Ten thousand hectares, it is roughly equal to 14.7 hundred million mu, nearly more than the 100 a city in the whole nation is seated salt-soda soil distributed area, and agriculture plantation causes because of salination
The underproduction, nearly 500,000,000 mu of old-field, be concentrated mainly on these arid and semi-arid lands of North China, northwest and northeast.In addition it cultivated
