Embodiment Construction

[0013] Diesel was selected as the single pollutant, and the tolerance range of calamus was obtained through preliminary experiments, and then six parallel concentrations were set, which were 0, 2000, 4000, 6000, 8000 and 10000 mg·kg -1 (Dry sand) mixed into medium (90mm×15mm) filled with 50g of dry sand sample, and 30 sterilized calamus seeds were selected and put into the medium, in artificial climate chamber (28°C, 12 / 12h) Cultivate for 50 days, regularly observe the germination of calamus seeds, and add sterile water in time. During the test, pay attention to keep the water content of each medium consistent, and keep the sandy soil moist and with a certain water content.

[0014] After the calamus grows to 30 days, when the growth of calamus in each culture medium can be clearly distinguished, three calamus plants with the same growth and similar biomass are taken in each petri dish for test 1, and at the same time, they are separately grown in each petri dish. Three calamu...

Abstract

The invention relates to a method for representing physiological response characteristics of Acorus calamus under diesel pollution stress. The method particularly comprises the following steps of: dying Acorus calamus leaf tissues by using benzidine; and measuring concentration of hydrogen peroxide in the Acorus calamus leaf tissue cells, wherein the concentration is less than 10,000 mg.kg<-1>. According to wetland environments polluted by diesel, a research method for representing plant physiological response characteristics of the Acorus calamu under diesel stress is tested and explored, and a uniformly regulated biological method for representing physiological response characteristics of a plant under petroleum pollutant stress and a system for monitoring plant damage caused by oil environmental pollution are established, so that the wetland soil environments polluted by a petroleum pollutant can be repaired well, and oil environmental pollution risk evaluation research can be performed effectively.

Description

technical field [0001] This patent relates to a calamus ( Acorus calamus Linn ) to characterize the physiological response characteristics of diesel stress. Background technique [0002] With the development of the petrochemical industry, accidents such as pollution, omission, blowout, and oil pipeline leakage occur frequently during the large-scale exploitation, smelting, transportation, use, and treatment of oil, and the scale of offshore oil operations is getting larger and larger. As the seawater washes the oil spilled into the offshore and coastal wetlands, the spilled oil will gradually undergo physical weathering (such as evaporation, emulsification, diffusion, dissolution, adsorption and sedimentation), chemical weathering (mainly photodegradation) and biological weathering (mainly biodegradation) and so on. After the spilled oil enters the water body, the thick oil film will quickly spread around. When the oil layer becomes thinner and broken into pieces, the area...
