Description
Technical field
The present invention relates to soil improvement recovery technique, especially a kind of oyster shell soil conditioner and preparation method thereof and
The purposes of Rice Cropping.
Background technique
Acidified soil area in China's accounts for about the 23% of national total area, is mainly distributed on the south the Changjiang river up to 200,000,000 hectares at present
14 provinces and regions, wherein pH<6.5 soil ratio is extended to 65%, pH by 52% before 30 years<5.5 soil is expanded by 20%
Greatly to 40%, pH<4.5 soil is extended to 4% by 1%.Soil acidification will will lead to Nutrient Elements in Soil loss, toxic heavy
The solubility of metallic compound increases, and soil fertility reduces, and soil texture is deteriorated, and influences ground crop growthing development, sternly
The sustainable development of the recasting about grain security in China and agricultural.
According to statistics, China is by the cultivated area of the heavy metal pollutions such as Cd, AS, Cr, Pb close to 2 × 10hm2, it is total to account for about arable land
The 1/5 of area.Heavy metal element is not only with single-element contaminated soil, while when various heavy coexists in the soil, they
Between there is also collaboration, antagonism, be further exacerbated by the combined pollution of soil.Every year because heavy metal pollution causes grain to subtract
It produces more than 1 × 107Ton, and the contaminated by heavy metals grain that cannot be eaten then is up to 1.2 × 107Ton adds up to economic loss at least
20000000000 yuan (Agricultural Sustainable Development in China and overall national strength study group, 1995).In Toyama County, Japan " ostalgia occurs for the sixties
Disease ", be caused by edible " Cd meters " produced by the soil of Cd contaminated wastewater of local resident (《Heavy-metal contaminated soil
Phytoremediation research》, Jiang Xianjun etc.,《Soil》, the 2nd phase in 2000).And the current rice cadmium excessive problem in China is also more and more prominent
Out, the ground such as China Hunan, Guangdong expose rice " heavy metal cadmium " event, the rice main product of Heilongjiang Province three in 2016 in succession
Area's heavy metal cadmium it is exceeded (《Heavy metal lead, cadmium, chromium content status investigation in the different producing area polished rice of Heilungkiang》, Xie Feng is graceful etc.,
《Food industry》, 02 phase in 2018), in one, the persimmon bamboo plantation periphery in Chenzhou, Hunan Province area village, local resident passes through rice and vegetable
The average daily cadmium intake of dish up to 596 micrograms (cadmium rice is worth whole society's concern, ten thousand big vast richnesses etc., democracy and science, 2016 the 6th
Phase).The problem for showing that cadmium content is exceeded in soil is urgently to be resolved.
China's oyster culture amount ranks first in the world.According to statistics, national oyster yield in 2016 reaches 483.50 ten thousand tons, accounts for generation
The 81.50% of boundary's total output.Coastal area oyster shell is resourceful, only by taking Zhangzhou City Zhaoan County as an example, as Fujian Province's maximum
Oyster hanging culture base, Zhaoan produces 9.2 ten thousand tons of oyster per year, but leaves the oyster shell more than 80,000 tons, and oyster shell once no
To being effectively treated, solid waste just will become, it is difficult to be cleared up in a short time by environment.The processing mode of oyster shell is still at present
The stage that oyster shell is poured into sea is rested on, this will cause larger solid pollution to marine environment.
Oyster shell is to be adjusted to be formed by biomineralization by organic matter, i.e., with a small amount of organic matter macromolecular (protein, sugared egg
White or polysaccharide) it is frame, molecule manipulation, the multiple microlayer structures of the high-sequential of composition are carried out as unit of calcium carbonate.Oyster
Main component in shell is calcium carbonate, and calcium carbonate accounts for 90% or more of oyster shell quality.Oyster shell contain the organic matters such as nitrogen, phosphorus and
Mineral element necessary to the biological growths such as calcium abundant, potassium, iron, magnesium, sodium, therefore can directly be applied using oyster shell as fertilizer
In soil.Oyster shell lacks calcium carbonate to improvement and in acid soil, effect is particularly evident in alkalinity.Oyster shell it is natural
Porous structure have certain suction-operated, by fertilizer it is in combination after, be conducive to the rate of release for slowing down fertilizer, can play
Fertilizer conservation and the effect for improving utilization rate of fertilizer.
