[0002] Tea tree is a plant with extremely high economic value, and its cultivation and management require sophisticated technology and scientific methods. The leaves of tea tree can be made into tea, which is rich in various nutrients and has special medical and health care functions. In addition to lowering cholesterol and preventing atherosclerosis, it also has a good preventive effect on radiation, cancer, anemia and other diseases. Tea tree cultivation is a delicate and complex process that requires comprehensive consideration of multiple factors and corresponding management measures. Through scientific cultivation and management techniques, the yield and quality of tea trees can be improved, and the sustainable development of the tea industry can be promoted. α-Farnesene is an important sesquiterpenoid compound that is found in many plants, including tea trees. It exists as an aroma component in tea and has an important influence on the aroma quality of tea. The α-farnesene content in tea varies depending on factors such as tea type, growth environment, picking season and processing technology.

[0003] The existing application number is CN202420031882.7, which is a shade device for tea planting. It includes a main block, a secondary block is arranged at the other end of the main block, and a shade net is arranged on the top between the main block and the secondary block. Universal wheels are installed at both ends and both sides of the bottom outer walls of the main block and the secondary block, and a limiting mechanism for fixing the other end of the shade net is arranged on the top of the secondary block. According to this technical solution, when the shade net is not needed and needs to be stored, the limiting mechanism is started to cancel the limiting fixation of the other end of the shade net, and then the shade net can be collected and stored by starting the placement mechanism. The recovery and storage of the shade net is relatively simple, which greatly reduces the workload of the staff.
