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 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.
