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 made up of the material that thousands of kinds of chemical property are different, 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 product, incomplete combustion thing to descend slowly and lightly etc. and cause a series of soil petroleum pollution problem.The ground crude oil that particularly oil production process produces, has become the important sources of soil mineral oil pollution.Much research shows, petroleum hydrocarbon enters after in animal body, has carcinogenic, teratogenesis, mutagenic effect to mammal and the mankind.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, of the present inventionly a kind ofly be suitable for petroleum hydrocarbon contaminated soil culture medium, 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 containing 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 microorganism, can suppress the breeding of pathogenic bacteria, wherein nettle grass and rye grass are the plants of the ability with excess absorption and accumulation petroleum hydrocarbon, use rhamnolipid can strengthen the reparation of nettle grass to soil further.
