Abstract
The invention discloses a soil culture medium applicable to polychlorinated biphenyl pollution, which comprises the following components in parts by weight: 20-40 parts of clay, 20-25 parts of smectite, 60-90 parts of organic matter, 2-4 parts of rhamnoilpid and gramicidin, 3-5 parts of slow-release fertilizer, 0.5-0.8 part of pellet agent and 1-3 parts of plant seed. The soil culture medium can lower the influence of polychlorinated biphenyl pollution on plant growth.
Description
technical field
The present invention relates to a kind of soil culture medium for soil improvement, especially a kind of plant-growth soil culture medium that is specifically designed to pollution by polychlorinated biphenyles.
technical background
Persistence organic pollutant (persistent organic pollutants, POPs) be that a class has toxicity, persistence, is easy to the organic compound of enrichment in vivo and long-distance migration and deposition, can near source or environment at a distance and human body produce infringement.Persistence organic pollutant can circulate in the world by atmosphere, ocean current and alternate manner, and the pollution problem that they cause has become global environmental problem.Polychlorobiphenyl is most typical difficult degradation organochlorine contamination thing, has the feature of low water solubility, fat-solubility, and in many industrially developed country, because the long-term of PCBs makes soil and sediment suffer severe contamination in a large number, soil fertility is poor, is unfavorable for plant-growth.Therefore we need to improve the soil of pollution by polychlorinated biphenyles, and general soil culture medium can not meet the condition that woody plant community, xylium forms at all, therefore just need to develop a kind of raw material sources extensive, the artificial soil preparation method of best living environment can be provided for plant.
Summary of the invention
The object of the invention is to the soil for pollution by polychlorinated biphenyles, the artificial soil substratum that a kind of raw material sources are extensive, with low cost, can turn waste into wealth is provided.
For realizing above object, a kind of soil culture medium that is suitable for pollution by polychlorinated biphenyles of the present invention, its component and weight part thereof are: clay 20-40 part, montmorillonite 2 0-25 part, organic 60-90 part, rhamnolipid and linear gramicidins 2-4 part, slow-release fertilizer 3-5 part, granule agent 0.5-0.8 part, plant seed 1-3 part.
Described organic matter is animal fat and animal excrement.
The mass ratio of described rhamnolipid and linear gramicidins is 1:2-6.
Described plant seed is mixed and is formed by shrub seeds and herbaceous seeds, and its mass ratio is 5-10:1.
Described slow-release fertilizer is composite fertilizer special and calcium superphosphate, and described composite fertilizer special and calcium superphosphate volume ratio are 1:1, and described composite fertilizer special is the fertilizer that contains nitrogen, phosphorus, potassium nutrition, and wherein the weight ratio of nitrogen, phosphorus, potassium is 1.5:1:1.
The beneficial effect that the present invention produces is that soil culture medium of the present invention can reduce the impact of pollution by polychlorinated biphenyles on plant-growth, has stronger resistance to organic contamination, Salt And Alkali Tolerance, barren-resistant ability and nutrient acquisition capability; Substratum is slightly acidic state, is suitable for perching various microorganisms, can suppress the breeding of pathogenic bacteria.
