Description
Technical field
The present invention relates to a kind of using soil conditioner of marine animal and plant residuum production and preparation method thereof, belong to ocean
Waste's reclamation technical field.
Background technology
Soil conditioner was agriculturally progressively starting to apply in recent years, and the change of soil aciditiy refers to hydrogen ion in soil
The change of concentration, from the early stage eighties in last century so far, the pH value of all soil types almost found in China all have dropped
0.13-0.80, the continuous acidifying of soil also have the trend developed.That is, due to the influence of the unreasonable production activity of the mankind,
China's soil acidification is greatly accelerated, it will great harm is caused to ecological environment and human survival.
The area of China's acid soil is about 200,000 km2, account for 21% of national total area or so.The big portion of these acid soils
PH value is divided to be less than 5.5, wherein more pH value is less than 5.0, even as low as 4.5.These soil irrational land use, plough
Manage down, acidizing degree is increasingly serious, as agricultural production obstruction factor.Current National soil acidity or alkalinity (pH) 30 years
0.6 unit is averagely have dropped, acid cultivated area (pH ＜ 5.5) rises to current 18% from 7% before 30 years.South
Ratio of 14 provinces (the area, city) soil pH value less than 6.5 is expanded to 65% by 52% before 30 years, pH value less than 5.5 by 20%
40% is expanded to, pH value is expanded to 4% less than 4.5 by 1%.The ground pH value such as the Guangdong, Guangxi, Sichuan of most serious are acidified to be less than
4.5 arable soil ratio is respectively 13%, 7%, 4%.Soil (the 0-20cm layers of In Yujiang County, jiangxi Province Red Sandstone parent material development
It is secondary), determined through 1980, wild grass ground pH value 4.84, low yield paddy field pH value 5.90；And 1996 sample survey with the sample point
Fixed, wild grass ground pH value is 4.67, have dropped 0.17, low yield paddy field pH is 4.89, have dropped 1.01.
In recent years, the report on the nonacid soil acidification of northern China also gradually increases.According to investigations, Area in Yantai Region apple
Different degrees of acidifying occurred for Orchard Soil, the proportion of soil pH≤5.5, is arranged as in order：Zhaoyuan 32.03%, Peng Lai
29.88%th, Qixia 27.7%, Longkou 15.73%, significantly lower than the pH value of overall survey of soil the 1980s.
Statistics shows, Shandong Province's year pure chemical fertilizer dose up to 472.7 ten thousand tons, utilization rate of nitrogen fertilizer is 30% or so,
Only the 1/2 of developed country's level, remaining is all residued in soil.Average 27.2 kilograms of the fertilizer amount of mu is broadcast, it is more flat than the whole nation
Equal dosage is high 6 kilograms, higher than world average dose 19.2 kilograms.
The consequence of Use out of range chemical fertilizer is soil acidification, secondary salinization exacerbation.Soil acidification speed in Shandong adds in recent years
It hurry up, Jiaodong Areas is especially prominent, and acidifying area of the pH value less than 5.5 is up to more than 980 ten thousand mu.13,000,000 mu of layout plannings of the whole province
In, there are 2,600,000 mu of generation secondary salinizations.
Soil acidification causes soil nutrient out of proportion, and crop incidence of disease rise, quality of agricultural product declines.PH value is less than
4.5 plot, it can typically cause crop failure more than 30%.After layout planning is planted 4 years, soil salinization phenomenon increases year by year
Add, have a strong impact on crop yield and quality.
Some vegetables flakes in Shandong, due to Use out of range chemical fertilizer for years, land quality degradation,
It also result in " chemical fertilizer dependence ".Some places have to carry out soil displacement from the Northeast's drawing come black earth with train.And replace
The soil gone out, even if not using chemical fertilizer, also difficulty grows fine in several years of crops.
The soil conditioner of domestic improvement acidified soil is mostly traditional calcium hydroxide (dolomite ash), calcium carbonate at present
Based on (magnesium), calcium silicates (magnesium, potassium) etc., different administration limitations all be present.
Calcium hydroxide, this is acidic soil conditioner the most remote, and chemical property is highly basic, and the reaction with soil is neutralization
Reaction, neutralization reaction is violent exothermic reaction, can injure edaphon, and the plain toxic agent of generally making to disappear uses, and excess or is applied
Local soil may be caused to cross alkali or caused soil hardening with uneven.Single calcium nutrition can be provided, but without other battalion
Support effect.
Lime stone, dolomite, causticity legal system alkali residue, main component is all calcium carbonate, and some contain magnesium carbonate.Calcium carbonate
Reaction with soil is metathesis reaction, due to the fixation of sulfate radical and the precipitation of carbon dioxide, weakens soil acidity, pH is carried
Height, but to faintly acid soil, because when soil pH reaches 5.8, just can not separate out, so opsonic action has certain limitations.
Silicate containing elements such as calcium, magnesium, after activation process, can with soil acid reaction, it is micro in contained
Plant nutrient has plant absorption active, still, simply with industrial slags class silicate such as blast furnace water quenching slag, cinder etc.
Directly make acidic soil conditioner, easily cause Heavy Metal Pollution, various mine tailings also can not necessarily be used for manufacturing soil conditioning
Agent, perhaps can also secondary hazards be caused to soil.
In recent years as seashells cultivate the expansion of scale, a large amount of shellfishes remained in seashells process of manufacture
Discarded object, by taking oyster shell as an example, the oyster shell of the only annual output in city of Weihai in Shandong province is about ten thousand tons of 30-40, and an only small part obtains
Reasonable utilization has been arrived, it is most of not to be utilized effectively and deal carefully with, rural environments are seriously polluted, directly affects town and country
The improvement of human settlement and new countryside construction.And the material composition of oyster shell is divided into inanimate matter and organic matter two parts, inanimate matter
Based on calcium carbonate, account for more than the 90% of oyster shell quality, wherein calcium constituent accounts for 39.78%-40.23%, additionally containing copper,
The various trace elements of zinc, manganese, strontium etc. 20, the organic principle of oyster shell account for the 3-5% of oyster shell quality, contain glycine, Guang
17 kinds of amino acid such as propylhomoserin, methionine, can be absorbed and used by plants after activation process.
Sea shells tradition and conventional processing mode directly utilize after simply simply crushing, and active ingredient therein needs
To pass through the long-term conversion of soil can just be absorbed and used by plants, and effect is slow, and this is also that peasant is unwilling to adjust using such soil
The main reason for managing agent.
The A of Chinese patent literature CN 102321484 (application number 201110154187.7) disclose a kind of improvement acidifying or
The organic environment-friendly soil conditioner of acid soil.This patent using biogas residue, oyster shell whiting, calcium magnesium phosphate, plant ash, chitosan,
Zeolite powder, bentonite are as soil conditioner.The A of Chinese patent literature CN 1502672 (application number 02135914.8) are disclosed
Soil conditioner based on oyster shell.It is characterized in that by oyster shell powder, polyaspartic acid salts, chitosan or derivatives thereof, life
The all or part of powder of thing or fermentate are formed.
Above-mentioned two patents are to improved soil shape, increasing soil fertility has certain effect, but the nutrition that raw material provides
Components utilising is insufficient, limited to the effect of improvement crop quality.
