The significance of soil moisture and drought management system monitoring is reflected in the fact that public opinion monitoring can provide scientific guidance and direct services for agricultural structural adjustment and important agricultural activities. Secondly, public opinion monitoring can provide an evaluation basis for verifying the national project construction investment and the effectiveness of agricultural technology services. If the soil moisture is insufficient, the water content in the 0-50cm soil layer is less than 70% of the field water capacity, and the supplementary irrigation should be performed in time. Irrigation quota should be appropriate, to avoid excessive irrigation volume and heavy rainfall disasters after irrigation, generally a fixed irrigation volume of 30m3/mu, depending on the soil moisture conditions and determine the irrigation time. The tasseling period is both the peak period of water demand and the peak period of fertilizer demand.
What is important is that soil moisture and drought management systems provide a foundation for monitoring soil moisture for water cycle research, agricultural irrigation, rational use of water resources, and information collection for drought fighting. Doing a good job of soil moisture monitoring, guiding farmers to timely and rational fertilization, irrigating land, fighting drought, preventing disasters, and reducing disasters has important practical significance for increasing farmers' income. Soil moisture monitoring provides some references for the research and integration of agricultural drought-resistance and water-saving technologies. At the same time, through the exploration and innovation of new laws and technologies concerning the accumulation and evolution of information on soil moisture and drought management systems, it provides a rich foundation and results transformation.
The importance of information collection in soil moisture and drought management systems
The so-called soil moisture, soil moisture, usually indicates soil moisture content and soil relative humidity. The soil moisture evaluation index is expressed as a percentage of the ratio of soil water content to field capacity, and refers to parameters such as soil water holding capacity, soil properties, precipitation, and soil moisture records at the same period. Soil moisture and drought management systems are used to analyze soil moisture suitability for crop growth. And the possible impact of production, as well as precipitation and soil moisture changes in the same period.
