Description
Technical field
The invention belongs to soil conditioning technical field, and in particular to a kind of soil conditioner and its preparation method and application.
Background technology
Soil is the most basic means of production of the mankind, is material base for the survival of mankind, but is connected by turns for a long time
Kind, a large amount of consecutives such as chemical fertilizer of applying despise the cultivating under pattern of soil environment, national 1,800,000,000 mu of agro-farming soils have manifested difference
Degree matter of regional significance:Black soil of Northeast China organic matter significantly declines, southern arable soil acidifying aggravates, North China topsoil becomes easy and clean
Aobvious, northwest salinization of cultivated land is serious ..., and planting industry management department of Ministry of Agriculture correlation director introduces, and China carried out from 2005
Since fertilization compositions based on earth measurement works, chemical examination of fetching earth is carried out comprehensively, found out substantially " resources " of China's arable soil.Various places add up
Collection pedotheque 17,980,000, obtains all kinds of laboratory analysis of data 124,410,000, has tentatively found out 2498 counties（）
Arable soil nutrient situation, is particularly found that soil acidification, topsoil shoal, phosphorus nutrients are enriched with and the weight such as Soil Nutrients In Farmland is unbalance
Big common problem.
China's soil acidification area proportion in cultivated area is increasing, and soil acidification area in 2009 reaches to be ploughed
More than the 40% of ground area, and every year on average planting soil acidifying area about increased with 3.1% speed.The acid of China's soil
Change occurs mainly in acid soil in the south, is respectively red, yellow earth, these acid grounds major part pH ＜ 5.5, wherein more pH
＜ 5.0, or even pH ＜ 4.5.The annual of national soil acidity or alkalinity (pH) 30 have dropped 0.6, acid cultivated area (pH ＜ 5.5) from
Before 30 years 7% rises to current 18%, and in southern 14 provinces (city of area), the soil ratio of pH ＜ 6.5 is by before 30 years
52% soil for being extended to 65%, pH ＜ 5.5 is extended to 4% by 20% soil for being extended to 40%, pH ＜ 4.5 by 1%, is acidified most tight
The ground such as Guangdong, Guangxi, the Sichuan of weight, the arable soil ratio of pH ＜ 4.5 is respectively 13%, 7% and 4%.In recent years, with regard to China
The report of the nonacid soil acidification in the north is a lot of, especially the orchard of the non-calcareous parent material development in Bohai Sea Gulf, soil acidification problem
It is very universal.

The effectiveness of magnesium, making the absorbance of these elements reduces, and causes plant nutritional deficiency, and with soil acidification Al in soil can be brought3+From
The raising of son and other heavy metal ion activity, to soil and aerial plant harm can be all brought.Therefore, find suitable
Method or approach carry out acid soil improvement becomes the research topic of numerous researchers, and improvement acid ground also becomes agricultural
One important content of sustainable development.
The method of traditional acid soil improvement is that, with Calx or agstone, table mud acid degree is easy to by applying stone
Ash is reduced, and soil plough horizon commutativity Ca2+Concentration also can increased, but the impact to the acidity of subsoil will
It is more much smaller than topsoil.Excessive liming is possible to suppress the growth of crop, a large amount of or chronic administration Calx not only can cause
Soil compaction and form " the hardened field of Calx ", and can cause soil calcium, potassium, the dysequilibrium of 3 kinds of elements of magnesium and cause the underproduction,
The co-precipitation of magnesium and aluminum hydrated oxide can also be caused, the Mg in the soil liquid is reduced2+ Activity and plant availability.More
Soil is acidified again after seriously the alkalescence of soil presence multiple acidization, i.e. Calx is consumed after liming, and
Acidizing degree before liming than having aggravated.

Apply the higher fertilizer (such as During High-Temperature Composting or barnyard manure) of basicity also can effective control Farmland Soil Acidification, and can
Save and apply cost, improve the resource utilization of fertilizer.Because agricultural product are removed with fertilizer input for agricultural land soil acid
Change is reciprocal two process, and long-term fertilizer input can make up agricultural product and remove the soil alkali mineral loss for causing.But with
The quickening of urbanization, traditional compost and barnyard manure is fewer and feweri, and large-scale plant that raises apart from farmland farther out, cost of transportation is high,
Peasant is unwilling to invest.
Soil acidity can be reduced using microbe soil conditioner, Soil Available fertility is improved, decompose slow nutrient, be excavated
The keeping potential of soil, and carry out that soil remediation expense is low, environmental effect is little, but micro- life of improvement acidified soil is biased toward at present
