For a long time, people mainly concentrated on simple soil moisture research and ground vegetation research, such as soil moisture testing technology, extensive vegetation restoration, increased forest cover area, improved ecological environment, and neglected the connection between above-ground vegetation and groundwater. Xu Huacheng et al. used soil moisture meters to analyze the relationship between soil moisture seasonal changes and tree growth and drought tolerance. In the 1980s, dry soils in arid and semi-arid man-made forests generally appeared and became more and more serious. The increasing thickness of the dry layer, from the initial 2m to 10m, has begun to attract widespread attention in the forestry community.
Soil desiccation leads to soil degradation and vegetation growth decline. Serious artificial vegetation begins to yellow in large areas. After studying the dry soil layers of the Loess Plateau, the soil moisture analyzer concluded that, in addition to the above reasons, climate drought, reduced rainfall, decreased physical properties of soil moisture, and severe soil erosion are also the causes of soil desiccation. However, the water environment load, specific conditions The tree structure and density design have not been effectively solved.
Another important effect on soil moisture changes is the natural precipitation, the dynamic changes of soil moisture is affected by the seasons and the growth and development characteristics of vegetation. The soil moisture analyzer is used to determine the seasonal dynamics and vertical dynamics of soil moisture, and to control soil drying. The conditions can immediately take corresponding water technical measures to meet the demand of artificial vegetation for water and improve the utilization rate of natural precipitation. Therefore, the study of soil moisture dynamics is a focus of soil moisture research.
Jib cranes can be floor jib cranes and wall jib cranes. Floor Jib Crane is a floor fixed column jib crane for workshop, warehouse, wharf, etc. Wall cranes can be wall fixed jib crane and traving jib crane on wall rails, which needs no floor space and girder or beams like Bridge Crane, thus saving workshop space.
Jib crane is light crane for small capacity material handling commonly used at workshop, warehouse, wharf, production line, manufacturing production line, etc.
Jib crane capacity: 1t - 10t or custom
Lift height: 1m - 12m or custom
Work duty: A5, A6 or custom
