The phenotypes of crop yield, quality, stress resistance and other important traits are the result of the combination of genotype and environment. Therefore, in order to further improve the yield and quality of crop production, on the one hand, breeding should be optimized from the varieties, and On the one hand, it is necessary to carry out optimization guidance from the perspective of the environment to jointly promote the high quality and high yield of crops. To carry out research related to meteorological environment, we first need a hand-held meteorological instrument that can accurately and quickly measure meteorological parameters. The instrument is a kind of intelligent portable meteorological observation that integrates air temperature and humidity, light intensity, rainfall, wind direction and wind speed. Instruments, using handheld meteorological instruments for measurement and analysis, can better carry out agricultural research and research, further reveal the impact of meteorological environment on crops, and provide an important basis for high quality and high yield of agriculture. In-depth analysis of the plant growth environment is very important for the development of crop science. First, gene expression depends to a large extent on the environment in which plants grow. Second, gene localization and cloning depend on the environment in which phenotypic identification is performed. Third, many phenotypic identification processes, including bio-adversity and abiotic stress identification, are conducted in an artificially controlled environment. Finally, environmental measurements are becoming increasingly important for crop production processes. Therefore, the application of handheld meteorological instruments to reveal the impact of meteorological environment on crops has important application value in the field of agricultural research. At present, climate change has an increasingly important impact on crop growth and production. In this context, accurate determination and evaluation of all environmental factors affecting crop growth and development have become the key to future crop performance prediction and variety improvement. In order to reveal the specific effects of different meteorological environmental factors on different crops, in the past agricultural research process, a variety of agrometeorological instruments may be needed for measurement, such as temperature and humidity recorders, wind direction anemometers, rainfall recorders, etc. The use of a hand-held meteorological instrument, the combination of the main unit and different sensors greatly simplifies the measurement process, and the measurement of various meteorological environments can be carried out using only one set of instruments, which not only solves the problem of multi-instrument measurement, but also effectively The efficiency and effectiveness of scientific research have been improved, and the upgrading and development of the industry has been promoted.
An anchorage frame secures the Tower Crane mast to a structure or framework and provides stability when the tower crane is under load or experiencing wind forces. The number of Tower Crane Anchorage Frame is calculated by taking into account such factors as the type of tower cranes, jib length, height under hook, and maximum out-of-service wind speed.
