Background technique

China's water resources problems are very prominent. Water resources are in short supply, accounting for only 6% of the world's total. Moreover, water resources are unevenly distributed in time and space, and the matching degree of water and soil resources is low. Generally speaking, my country's water resources problems have a direct impact on food security. impact, that is, water resources and food security are a mutually causal issue. As rainwater is the key way to replenish water resources, the distribution of rainfall, the amount and time of rainfall are all very important, so it is necessary to study the relevant laws of rainwater.

At present, the research on rainwater often focuses on the division of regional climate types, rain detection and urban planning and many other aspects. In agriculture, the role of rainwater is self-evident. It is used to replenish surface water and groundwater to meet the growth of crops. Rain gauges are commonly used to collect rainwater-related data. The traditional rain gauges consist of two parts, including a measuring cup and a funnel. In the case of actual rainwater collection, under the influence of light, temperature and air flow fluctuations, a part of the rainwater will evaporate from the hole under the funnel, resulting in the loss of rainwater, inaccurate rainfall and the fractionation of hydrogen and oxygen stable isotopes in the rainwater. At the same time, due to the simple structure of traditional rain gauges, it needs to be collected every day during the rainy season. For areas like Hainan with long rainy seasons and frequent rainfall, it requires huge manpower and material resources. Therefore, the collected rainwater is only suitable for situations where the accuracy of rainwater is not high. For understanding a series of movements after rainwater falls on the surface, such as understanding the water migration of water in the agro-forestry complex system, the depth of water absorption by crops, and soil evaporation. And related researches such as crop transpiration are not accurate enough. Therefore, it is very necessary to develop an automatic rainwater collector that can solve the above problems.
