Technical field
The present invention relates to alkaline land soil improving technology field, more particularly to one kind can improve alkaline land soil situation and make
It can be adapted to soil conditioner of crop growth and preparation method thereof.
Background technology
In China there are substantial amounts of salt-soda soil, the yield of these soil Planting Crops is very low, or even total crop failure, on salt-soda soil
If not Planting Crops, let go unchecked, the soil that salt-soda soil can become better slowly corrodes, and the area in salt-soda soil can be increasing,
So administering and improving salt-soda soil, it is the matter of fundamental importance of state, is very urgent thing.
Desulfurated plaster is the discarded object after power plant desulfurization, and main component is calcium sulfate, also containing a certain amount of moisture.Because not
Can be directly as construction material and cement retarder, this gypsum is usually directly abandoned, and then occupies large amount of land resources.
Different from the natural gypsum, the particle of desulfurated plaster only has 50 microns, and specific surface area is very big.It is used to improve
Alkali-affected soil is quick, can not only solve desulfuration waste pollution tens million of tons annual, it is even more important that can also be China
Contribution green arable land.
Flyash is the primary solids waste of coal-burning power plant's discharge, is directly discharged in environment that environmental pollution can be caused.Chaff
Aldehyde slag is the poly-pentose in biomass class material such as corncob, cornstalk, rice husk, cotton seed hulls and agricultural byproducts processing leftover bits and pieces
The biomass class discarded object that component hydrolysis production furfural (furtural) produces, its bulk deposition can produce air, soil, river
Raw pollution.
