Abstract

The invention discloses a system for automatically and regularly collecting soil water in a layered manner. The system comprises a soil moisture layer collecting device, a soil moisture layer recycling device and a soil water regular recycling controller, wherein the soil moisture layer collecting device and the soil moisture layer recycling device are connected through a recycling guide pipe. The system is advantaged in that soil water can be automatically and regularly collected in a layered mode, investment of manpower and material resources in the soil water recycling process is reduced, and potential safety hazards are reduced; besides, the risk of isotope fractionation caused by contact between the collected soil water and the atmosphere can be reduced to a great extent, the isotope content in the soil water is kept unchanged in the long-time storage process, and the requirement for related research by applying isotope indexes in the soil water can be met.

Description

technical field [0001] The invention relates to a system for collecting soil water, in particular to a system for automatically and periodically collecting soil water in layers. Background technique [0002] Soil water is the material basis for plant growth and survival. It not only affects the yield of trees, field crops, vegetables, and fruit trees, but also affects the distribution of plants on the land surface. It also has an important impact on the growth of soil microorganisms and the loss of soil nutrients. The soil water content in different layers varies greatly. Therefore, in the study of water movement and chemical composition in stratified soil, water transformation (evaporation, transpiration) in different media, water movement in the soil-plant-atmosphere continuum (SPAC) and the availability of soil water to plants , and the use of isotope indicators for tracing and other aspects of long-term observation and research often require regular collection of soil w...
