The invention relates to a vanadium dioxide carbon fiber felt composite material, a preparation method and application thereof, and belongs to the technical field of electrode materials. The invention provides a method for preparing a vanadium dioxide carbon fiber felt composite material, comprising the following steps: a. Pretreatment of the carbon fiber felt: soaking the carbon fiber felt in acetone, then rinsing with water, drying, and heating at 100-200 DEG C for 3-3 5 hours, the treated carbon fiber felt is for subsequent use; b, preparation of ethylene glycol vanadyl solution: ammonium metavanadate: ethylene glycol is mixed in a ratio of 1: (5~10) by mass ratio, and the reaction generates ethylene glycol Vanadyl, for subsequent use; c, the preparation of composite material: put the carbon fiber felt obtained in step a into the ethylene glycol vanadyl solution obtained in step b and soak, then take out the carbon fiber felt, dry, then place in a tube furnace, pass through Enter N 2 , and react at 200~300℃ for 2~4 hours to obtain. The preparation method of the invention has a good prospect of popularization and application.

The invention relates to a cultivation method of genuine salvia, which comprises the following steps of: establishment of a salvia germplasm resource garden, selection of representative genuine salvia germplasm resources, identification of genuine salvia genome karyotype structure, determination of genuine salvia DNA bar codes, artificial mutation to obtain autotetraploid, sexual hybridization to obtain triploid salvia permanent hybrids, detoxification treatment, tissue culture seedling cloning and proliferation, bottle seedling transplanting, transplanted seedling management, new species comparison and testing, determination of the medicinal material yield and the main drug effective components, and genuine salvia new species determination and species identification. The genuine salvia obtained in the invention is, so far, the only population that has two great natural advantages: the polyploid advantage and the heterosis, and the advantages are giant and irreplaceable. Therefore, the method of the invention is an effective method for cultivating genuine traditional Chinese medicine with strong biotic stress and abiotic stress capability by using traditional Chinese medicine genuine functional genomes and feature genes and based on inherent genes of genuine traditional Chinese medicine.

The invention provides a picking method for fresh tea leaves. The picking method comprises the step that when standard bud leaves reach 60-100 per square foot and account for 50-90% of all the fresh tea leaves, mechanical picking is conducted on tea trees, wherein a tea picker with a mature leaf filtering device is preferably adopted for mechanical picking. By means of the picking method for the fresh tea leaves, mechanical picking is conducted within a specific time, the tea picker for mechanical collection is improved at the same time, the ratio of standard new shoots of mechanically-pickedtea leaves is increased, the miss picking rate is reduced, and processing and production of high-quality tea are facilitated; meanwhile, the labor intensity of tea leaf picking is also reduced, the production cost is reduced, and the sustainable development of tea production is improved.

The invention discloses a CGDD (Cumulative Growing Degree-Days) based method for improving the longan florescence rate and the fruit quality through flower forcing. The CGDD based method is established on the basis of the years of practical experience, a growing period and GDD (Growing Degree-Days) based innovative flower forcing technology is innovatively and systematically utilized, and the reasonable timing young sprout forcing, flower forcing and fruit setting is guided. The GDD are used for reflecting the accumulated heat of every growing period of longan trees under the actual environmental conditions and accordingly the flower forcing benefit of the GDD is remarkable and the accuracy is high. The expected accuracy of the expected effect of every growing period, namely the young sprout forcing period, the flower forcing period, the fruit setting period and fruit growing period, is within the range of plus or minus 5% through the CGDD. According to the CGDD based longan chemical flower forcing method, flower buds can be effectively induced, the physiological photosynthetic effect can be enhanced, the flowering and fruit setting of the longan trees can be promoted in a warm climate, the market sales production of logan fresh fruits is significantly improved, the fruiting can be achieved ahead of time, and high production economic returns can be obtained. According to the CGDD based longan flower forcing and management matching technology, the sustainable production of longan under the climate warming environmental conditions can be promoted.
