The invention discloses a soilless culture method of drought-resistant flowers in an open-air roof. The method comprises the following steps of: manufacturing ridges with height of 12-20cm at intervals in the open-air roof by sawdust cement paste; filling a soilless culture matrix composed of 30-50% of residue after mushroom plantation, 30-50% of sawdust, 5-10% of perlite, 3-5% of plant ash and 3-5% of calcium-magnesium-phosphate fertilizer to the ridges; cultivating drought-resistant flower seedlings in the soilless culture matrix; spraying water and killing insects in a wet condition; using 0.1-0.3% of urea and 0.3-0.6% of composite fertilizer water solution to pour the seedlings during the growth period. Plants with strong drought resistance, such as portulaca grandiflora, maguey, ball cactus, cactus, calendula officinalis and sago cycas, are applied to form a roof garden, which remains green, has flowers throughout the year, is colorful and has various shapes, thus saving labor, preventing heatstroke and protecting the roof surface as well as improving ornamental value, economic value, and greening economic, ecological and social effects.

The invention relates to environmental remediation technology for organic contaminated soil, specifically to a phytoremediation method of remedying petroleum hydrocarbon contaminated soil by using the ornamental plant Portulaca Grandiflora L. According to the invention, degradation of target petroleum hydrocarbon (TPH) in contaminated soil is promoted by using the absorption action of the plant Portulaca Grandiflora L. itself and degradation effects of root exudates and rhizospheric microorganisms of Portulaca Grandiflora L. When the plants of Portulaca Grandiflora L. are mature, the plants can be integrally removed from soil and sold as goods; it is not necessarily to remove the plants. Through repeated plantation of Portulaca Grandiflora L. and repeated absorption action and degradationeffects of Portulaca Grandiflora L., petroleum hydrocarbon pollutants in contaminated soil can be continuously reduced until the content of the pollutants reaches national environment standard or ecological safety level. The method has the advantages of environmental beautification, no need of disposal of planted areas, physical and chemical properties not destroying soil, no secondary pollution,low cost, appropriateness to large scale operation, treatment of pollution, improvement of environment, etc.

The invention discloses a preparing method for a liquid medium for increasing the cultivation survival rate of piper bambusaefolium and belongs to the field of artificial cultivation of the piper bambusaefolium. Cuttages of the piper bambusaefolium root difficultly under the environment where the temperature is low. The preparing method for the liquid medium for increasing the cultivation survival rate of the piper bambusaefolium is characterized in that firstly, clonazepam is pulverized, and the powdery clonazepam is added into water to be stirred to be dissolved; secondly, monopotassium phosphate is added into the mixture obtained in the first step, and stirring is carried out; thirdly, juice extracted from the overground portion of portulaca grandiflora is added into the mixture obtained in the second step to be mixed uniformly. The liquid medium can promote rooting.

The invention relates to a pure traditional Chinese medicine preparation for dental ulcers. The pure traditional Chinese medicine preparation is prepared from the following raw materials: 15 parts of white atractylodes rhizome, 15 parts of rhizoma zingiberis, 15 parts of uncaria rhynchophylla, 12 parts of curcuma zedoary, 12 parts of portulaca grandiflora, 12 parts of golden cypress, 10 parts of fructus gardeniae, 10 parts of licorice root, 10 parts of astragalus membranaceus, 10 parts of radix ophiopogonis, 7 parts of smoked plum, 7 parts of spica prunellae, 5 parts of cortex albiziae, 5 parts of muskmelon seeds and 3 parts of folium mori. When the pure traditional Chinese medicine preparation is used for treating the dental ulcers, the treatment course is short; the total effective rate is high; and the dental ulcers are difficult to relapse after being cured. In addition, the pure traditional Chinese medicine preparation is simple in process, so that the production cost is lowered; and the economical burden of a patient is lightened.
