Description
Technical field
The present invention relates to a kind of acid multifunctional soil quality improving agents and preparation method thereof, belong to environment remediation technical field.
Background technology
With the continuous development of economy and society, soil degradation problem becomes increasingly conspicuous, and is mainly shown as the salinization of soil, member
Plain unbalance, chemical contamination, the degeneration etc. of Organic Matter Loss and animals and plants fauna, seriously limit the development of fertility.
Saline-alkali soil is widely distributed on earth, and the whole world shares about 9.55 hundred million hm2, it is distributed in each continent arid area, it is main
Concentrate on Eurasia, Africa, America western part.Due to residing geographical location difference, weather conditions difference, salt-soda soil is in difference
The distribution of countries and regions also has very big difference.It is Australia, the former Soviet Union and China to be distributed at most.The total face of China's saline-alkali soil
Product is about 99,130,000 hm2, wherein modern saline-alkali soil area is 36,930,000 hm2, about 44,870,000 hm of remaining saline-alkali soil2, and still have
About 17,330,000 hm2Potential saline-alkali soil, be mainly distributed on northeast, North China, Northwest inland area and North of Yangtze River coastal area.
As soil pH ＞ 8, nitrogen-fixing bacteria activity reduces, and nitrification is suppressed.Phosphorus is in pH ＞ 7.5, then easy shape
At calcium dihydrogen phosphate.It is not easy to be absorbed by plants and utilize；When pH ＞ 8.5, soil sodium ion increases, and calcium and magnesium ion is substituted, shape
At carbonate deposition.Salinity is more, alkalinity is big, makes agron by leaching loss, and soil texture is destroyed, and venting and water permeable is not
It is good, cause crop quality to decline, even more so that plant wilt, poisoning and rotten death, influence the yield of crops, so necessary
Soil improvement is carried out to salt-soda soil.
There are water-saving irrigation, field drainage, farmland measure, biochemistry improvement skill for the treatment measures of the salinization of soil
Art.Soil improvement product is used and is studied and gradually favored at present
But study at present more material predominantly stay in inorganic material for example calcium gypsum, ardealite, zeolite, flyash,
Sludge, green manure, etc. the one or more mixing formula of natural materials modifying agent, it is single limited that there are improved effects, the duration
It is short, the problems such as the limitation of reserves.
