Description
Technical field：
The present invention relates to technical field of land improvement, and in particular to a kind of betterment of land agent being applied to after repeatedly cultivation.
Background technology：
Soil improvement is the bad quality and structure for soil, takes corresponding physics, biological or chemical measure, changes
Kind soil property, increases soil fertility, and increases crop yield, and improve the process of human survival soil environment.
Soil is after multiple plantation has been carried out, and the nutrient in soil can largely be absorbed, so as to cause in soil
Nutrient decline, more have in addition can result in soil stickiness increase, saline Land the problems such as generation；
Wherein saline-alkali soil is a kind of soil that salinization or alkalization are formed, including solonchak, alkaline earth and various salinized soils.
In arid and semi-arid lands, contained salinity in underearth and underground water, because evaporation from land acts on, with soil capillary
Pipe effect makes the waterborne of contained salinity be raised to surface layer, after moisture evaporation, salinity is stayed in upper soll layer, builds up and forming salt
Alkali.
The presence in salt-soda soil can seriously reduce the quality in soil, be unfavorable for plant growth, thus for repeatedly cultivation after
It is link indispensable during being reused to soil that soil, which carries out improvement,.
Otherwise the growing state of crop can be had a strong impact on, is unfavorable for the plantation of high-yield high-quality crop.
The content of the invention：
In view of the above-mentioned problems, it is applied to the soil after repeatedly cultivating the technical problem to be solved in the present invention is to provide a kind of
Modifying agent and preparation method thereof.
