The invention relates to the technical field of plant remediation of oil-contaminated soil, in particular to a method for treating and remediating oil-contaminated soil by using gaillardia aristata pursh flower plants. The method is to plant gaillardia aristata pursh in oil-contaminated soil. When the total petroleum hydrocarbon concentration of the soil is 10,000mg/kg, the growth amount of the plants is not inhibited basically, and the gaillardia aristata pursh can effectively degrade the total petroleum hydrocarbon in the oil-contaminated soil through the combined functions of the developed roots and root microbes to reduce the total petroleum hydrocarbon content in the contaminated soil. When the gaillardia aristata pursh is planted for 90 days, the degradation rate of the total petroleum hydrocarbon content in the contaminated soil can reach 56.63 percent which is nearly 4 times a blank natural degradation rate which is 15.49 percent. This proves that the gaillardia aristata pursh has high oil contamination resistance and high total petroleum hydrocarbon degradation capability. Thus, the total petroleum hydrocarbon in soil can be effectively removed by planting the gaillardia aristata pursh in the oil-contaminated soil, and removing all plants and well treating the plants in a centralized manner after the plants are mature.

The invention relates to a growth promoting agent for promoting photosynthetic bacteria strain to quickly breed and a using method of the growth promoting agent. The growth prompting agent is obtained as follows: adding 1 part weight of one or a mixture of sorbic acid, potassium sorbate or sodium sorbate to 1-4 parts by weight of alcohol for stirring, mixing and dissolving. The using method of the growth promoting agent is as follows: adding the growth promoting agent to a prepared photosynthetic bacteria liquid medium for stirring until the growth promoting agent is sufficiently dissolved; adding active photosynthetic bacteria strains for filling to a sealed or semi-open light transmission container for culturing at 25-32 DEG C by radiating under 1500lux-1600lux, wherein sorbate radial concentration of the growth promoting agent, which is added to the photosynthetic bacteria liquid medium, is controlled within a range of 0.005 mmol/L-1.0 mmol/L. The growth promoting agent for promoting photosynthetic bacteria strain to quickly breed is simple to use, less in usage, low in cost and capable of promoting photosynthetic bacteria strain to quickly breed. Moreover, the using method of the growth promoting agent is safe, ecological and environment-friendly and extensive in market prospect.

The invention provides application of pyridyl ancymidol compound in plant induced resistance. The compound is capable of obviously and rapidly improving the infection resisting ability of pathogenic bacteria of plants, and an active oxygen signal appears in advance, so that the phenomenon that cells die since the plants are infected by the pathogenic bacteria can be reduced, the growth of the pathogenic bacteria in the plants can be obviously inhibited, the plants are protected from being damaged by the pathogenic bacteria, the growth of the roots and seedlings of the plants can not be inhibited, and on the contrary, the plants are slightly stimulated to grow; the pyridyl ancymidol compound is capable of promoting the growth and the development of the side roots of the plants, and the secondary pollution to the environment caused by pesticide is not generated, so that the pyridyl ancymidol compound has a wide application value.

The invention discloses a static fermentation process for dark tea. The static fermentation process comprises the following steps of (1) extracting capsaicin: (1A) preparing materials: preparing Guizhou red peppers as raw materials; (1B) performing drying; (1C) performing crushing; and (1D) performing extraction: mixing red pepper powder with a leaching solution to obtain a mixture, putting the mixture in a thermostatic waterbath pot of 50 DEG C for leaching for 60min, continuously performing stirring during leaching, then performing filtering with a dual filter paper to obtain a solution I, and putting a recovered solvent into the solution I, and performing concentration so as to obtain the capsaicine; (2) selecting materials; (3) performing rolling; (4) performing muffling in a piling manner: spreading a wet cotton cloth on the floor of a fermentation room, putting rolled leaves on the wet cotton cloth, and performing piling until the pile height is 65-70cm; and(5) performing drying: controlling the drying temperature to be 112-115 DEG C until the water content of dried tea leaves is reduced to be 30%. Black tea is used as a raw material for processing the dark tea, so that the quality achieves or exceeds requirements for the quality of conventional dark tea, also a fixation working procedure is omitted, and the pile fermentation time and the processing cycle of the dark tea are shortened, so that the production cost is reduced, and the whole benefits of dark tea industry can be increased.

The invention discloses a method for repairing arsenic contaminated soil by using pteris vittata. The method comprises the following steps that S1, soil plowing is carried out in an arsenic contaminated area, wherein the soil arsenic content of the arsenic contaminated area is 60-120mg/kg, and then according to application of urea 60-80kg/mu and potassium chloride 40-60kg/mu, applying of Ca(H2PO4)2 is carried out at the same time to enable the phosphorus content in the soil to reach 200-800mg/kg; S2, pteris vittata seedlings are planted according to the density of 3000-5000 plants/mu; and S3,after the pteris vittata grows 100-140 days, the aboveground parts and the root parts of the pteris vittata are harvested. The method can improve the adsorption capacity and enrichment coefficient ofthe pteris vittata, and phosphorus and arsenic do not have an antagonistic effect and even have a synergistic effect at a high concentration. The method has the characteristics of low cost, large biomass, high adaptability and no secondary pollution.

The invention relates to a northern overwintering pond water quality treatment method which comprises the following steps: uniformly splashing a microbial agent into a northern aquaculture pond in autumn within the splashing range of the water surface of the whole pond; when the water body is a water body with advantages formed by single algae, namely the color of the water body is yellow (chrysophyta), red (dinoflagellate) or yellow green (diatom and dinoflagellate), bacillus coagulans is selected as the microbial agent, the use amount of the microbial agent is that one kilogram of the microbial agentis used for every3-4 mu of water surface, and the microbial agent is mixed with water to be uniformly splashed; when a water body is not a dominant water body formed by single algae (most algae are Dinoflagellates such as dinoflagellates, chrysophyta and euglena), a disinfectant is splashed to 1/4-1/3 of the water surface of the pond, a microbial agent rhodopseudomonas palustris is mixed with water to be evenly splashed after 10-15 days, and 0.5-1 L of the microbial agent is used on every 1 mu of water surface with water depth smaller than 2 meters.
