Abstract
The present invention relates to a kind of nano modification soil, are mixed by the component including following parts by weight：30 70 parts of fertile soil, 15 45 parts of mycorhiza, 1 10 parts of water-retaining agent, 3 15 parts of soil property conditioning agent, 1 10 parts of nano modifier.Nano modification soil provided by the invention has many advantages, such as that full of nutrition, good water-retaining property, bioactivity are strong, can improve pollutant capacity of decomposition.
Description
Technical field
The invention belongs to field of plant growing technology, and in particular to a kind of nano modification soil.
Background technology
Northern China arid, water shortage, rate of vegetation are low, and sandstorm, dust and sand weather take place frequently, and frequently occur in recent years in addition
Haze, seriously affected the development of people’s lives and national economy.
Soil is used not only for storage, supply nutrient, and various nutrients all carry out a series of biologies in the soil
, chemical and physics transformation.Soil is the underlying carrier of agricultural, and basic effect is to provide one surely for crop
Fixed, suitable root system environment, such as moisture, air, nutrient, ph value, this is all related with the physicochemical property of soil matrix；Simultaneously
Soil is also the underlying carrier that natural environment reduces pollutant, soil, micro- because having microorganism, plant and animal in soil
Biology, the physics of plant, chemistry, the triple synergistic effects of biology, can degrade nature pollutant, and the mechanism of action includes inhaling
Attached, delay, filtering, redox, precipitation, microorganism decomposition, conversion, plant masking, residue accumulated, water transpiration and nutrient
Absorption and the effect of all kinds of animals.
But function of the soil in natural environment in terms of reducing pollutant is limited, especially in the city of modernization, from
Soil storage in right environment is fewer and fewer.It is desirable to while building high-quality urban green space, improve air quality, realize
The target of environment sustainable development.
Invention content
In view of the deficiencies in the prior art, the object of the present invention is to provide a kind of full of nutrition, good water-retaining property, biologies
Active nano modification soil strong, that pollutant capacity of decomposition can be improved.
To achieve the above objectives, the technical solution adopted by the present invention is：A kind of nano modification soil, by including following weight
The component of part mixes：
Further, nano modification soil is mixed by the component including following parts by weight：
Further, the water-retaining agent is one or more in Sodium Polyacrylate, polyacrylic acid potassium, polyacrylamide.
Further, the soil property conditioning agent is mineral powder.The granularity of mineral powder is 80-1000 mesh.The soil property tune of the present invention
Section agent is mainly used for adjusting the content and soil acidity or alkalinity of phosphorus, potassium, calcium, magnesium, iron etc. in soil.
Further, prepare mineral selection used by mineral powder from zeolite, diatomite, perlite, sepiolite, bentonite and
It is one or more in lime stone.
Further, the nano modifier is selected from nano silicon dioxide, nanometer sodium metasilicate, nanometer calcium silicates, nanometer phosphoric acid
It is one or more in sodium, nano-calcium phosphate, nano zine oxide, nano-calcium carbonate.The nano modifier of the present invention is mainly used for
The activity of Soil Microorganism is adjusted, capacity of decomposition of the soil to pollutant is improved.
Further, the grain size of the nano modifier is 10-120 nanometers.
In the present invention, appropriate common plantation can be added into above-mentioned nano modification soil according to the needs of practical application
Soil（Such as garden mould, sand soil）, animal excreta, porous material after sterilization（Such as smoked charcoal）Deng.
A kind of nano modification soil provided by the present invention, has the following advantages：
The first, water-retaining property is strong.The nano modification soil of the present invention can quickly drink up the rain, irrigation water and save,
The moisture content needed for normal plant can have not only been can guarantee in this way when plant needs, but also can prevent because evaporating, oozing with slow release
Leakage is lost in and moisture content is made to slattern, and ensures that soil keeps moistening for a long time, can absorb water repeatedly, waterproof, is slowly sent out for vegetable seeds
It educates.
The second, full of nutrition.In addition to containing micro- life possessed by fertile soil, mycorhiza in the nano modification soil of the present invention
Object, also containing the abundant minerals needed for plant growth（Such as phosphorus, potassium, calcium, magnesium, aluminium）, these minerals can be by soil property
It conditioning agent and/or provides for adjusting the nano modifier of microbial activity.
Third, bioactivity are strong, can greatly improve the ability of soil decomposing pollutant.
