The survival rate and growth rate of cutting seedlings are affected by temperature and humidity, and they are most vividly displayed in the process of autumn tea spike insertion. The early high temperature and high humidity conditions can significantly improve the survival rate of tea seedlings. Therefore, it is very important to manage the temperature and humidity of tea seedlings. By constructing a heat preservation shed, the temperature and humidity in the shed can be effectively increased, and the growth of tea plants can be promoted. However, the control of temperature and humidity is still relatively difficult, for which purpose monitoring and management can be performed using a temperature and humidity monitor to provide a scientific digital basis for the growth of tea plants.
Two treatments were set up in the test, one was to construct a small arch shed to cover the shading net, and the other was to cover the shading net as a control. On October 16, 2011, after the first week of cutting, the autumn tea plantings were divided into 2 plots. One plot covered the insulation film and shade net (shading net in the outer layer) at the same time as a greenhouse; another plot Keep unchanged as a control. In the shed are placed in the temperature and humidity monitor, record air temperature and humidity every 1h. After 3 weeks of treatment, 21 tea plants were randomly selected from the treatment of the greenhouse and the control, and the plant height and callus rate were counted. At the same time, another 200 tea plants were harvested for each treatment. The sprouts were carefully peeled from the tea plants and immediately frozen in liquid nitrogen, and then stored at -70°C until use.
Through the real-time temperature and humidity records of the temperature and humidity monitor, it was found that the treatment of the greenhouse can significantly increase the temperature and humidity needed for the growth of the tea seedlings. Taking the change in temperature and humidity of the insulation shed and the control on October 24 as an example, the insulation shed can increase the temperature by 1.7 to 12.6°C, with an average increase of 5.15°C and a humidity of -12.5% ​​to 37.6% with an average increase of 5.10%. The data collected was particularly significant at 8 to 17 hours (daytime), indicating that the insulation shed has a good effect of heat preservation and moisturizing. Temperature and humidity are the main environmental factors that determine the growth rate and geographical distribution of tea plants. The early stage of tea growth requires higher temperature and humidity. Therefore, the use of heat preservation sheds can better solve the requirements of high temperature and high humidity for the growth of autumn and winter tea seedlings. Photosynthesis ability has extremely important significance for the growth of seedlings.
Through the analysis of temperature and humidity monitoring of tea seedlings using temperature and humidity monitor, it can be shown that high temperature and high humidity can promote the growth of tea seedlings. The induction of buds by temperature and humidity changes involves a variety of physiological and biochemical processes, and many genes are involved. The selected genes laid the foundation for further research on understanding the growth mechanism of tea plants and cloning of related genes.
