Abstract
The invention discloses a soil culture medium applicable to petroleum hydrocarbon pollution, which comprises the following components in parts by weight: 30-40 parts of clay, 10-15 parts of smectite, 50-70 parts of organic matter, 2-4 parts of rhamnoilpid, 3-5 parts of slow-release fertilizer, 0.5-0.8 part of granular binding agent for pellet, 1-3 parts of nettle seed and 1-2 parts of ryegrass seed. The soil culture medium can lower the influence of petroleum hydrocarbon pollution on plant growth.
Description
technical field
The present invention relates to a kind of soil culture medium for soil improvement, be especially a kind ofly specifically designed to petroleum hydrocarbon contaminated plant-growth soil culture medium.
technical background
The complex mixture that oil is comprised of the thousands of kinds of different materials of chemical property, the pollution of the exploitation of oil, smelting, use and transportation and omission accident, and the discharge of oily(waste)water, sewage irrigation, the volatilization of various petroleum products, incomplete combustion thing descend slowly and lightly etc. and to cause a series of soil petroleum pollution problems.The ground crude oil that particularly oil production process produces, has become the important sources of soil mineral oil pollution.Much research shows, after petroleum hydrocarbon enters in animal body, mammal and the mankind had to carcinogenic, teratogenesis, mutagenic effect.The severe contamination of soil can cause some composition of petroleum hydrocarbon to accumulate in grain, affects the quality of grain, and by food chain, harm humans is healthy.
Summary of the invention
The object of the invention is to for petroleum hydrocarbon contaminated soil, 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 petroleum hydrocarbon contaminated soil culture medium that is suitable for of the present invention, its component and weight part thereof are: clay 30-40 part, montmorillonite 10-15 part, organic 50-70 part, rhamnolipid 2-4 part, slow-release fertilizer 3-5 part, granule agent 0.5-0.8 part, nettle grass seed 1-3 part, ryegrass seed 1-2 part.
Described organic matter is animal fat and animal excrement.
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 petroleum hydrocarbon contaminated impact 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, be suitable for perching various microorganisms, can suppress the breeding of pathogenic bacteria, wherein nettle grass and rye grass are to have the plant that excess absorbs and accumulate the ability of petroleum hydrocarbon, use rhamnolipid can further strengthen the reparation of nettle grass to soil.
