The effect of the saline-alkali land soil conditioner that Application Example 1-3 is prepared for the inventive method is described.
The soil weight refers to the confession dry weight of unit volume soil in its natural state, is that of soil density is basic
Physical property index, has the biggest to the anti-candle ability etc. of invading of permeability, moisture holding capacity, solute migration feature and the soil of soil
Impact, the soil weight is the least, and porosity of soil is the highest.Saturated soil water content refers to when all water in soil aperture is be full of
Water content, invades candle with soil, Contaminants Transport is closely related.After field capacity then refers to get rid of gravitational water in soil, hollow billet
Water content time suspended water reaches most, is considered the upper limit of Available sulfur.
Selecting the soil in western somewhere, salinity is about 1%, carries out spilling and executes soil conditioner prepared by the present invention,
And measuring relevant parameter respectively, concrete data are as shown in table 1.
Table 1
It can be seen that the soil conditioner water retention of the present invention is high from the data of table 1, the soil weight reduces, soil hole
Gap rate improves, and is thus advantageous on alkaline land soil plant vegetation.
