The so-called soil moisture, soil moisture, usually indicates soil moisture and soil relative humidity. The soil moisture evaluation index is expressed as a percentage of the ratio of soil water content to field water holding capacity. Referring to soil water holding capacity, soil properties, precipitation and soil moisture, the soil moisture and drought management system analyze soil moisture suitability for crop growth. And the possible impact of production, as well as precipitation and soil moisture changes over the same period.

The significance of soil moisture and drought management system monitoring is first reflected in the fact that public opinion monitoring can provide scientific guidance and direct service 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 agricultural technology service effectiveness. If the soil moisture is insufficient, the water content of 0~50cm soil layer is lower than 70% of the field water holding capacity, and the irrigation should be carried out in time. The irrigation quota should be appropriate to avoid excessive irrigation and rain and heavy rain damage after irrigation. Generally, the irrigation quota is 30m3/mu, and the irrigation time is determined according to the soil moisture. The tasseling period is both the peak period of water demand and the peak period of fertilizer demand.

It is important that the soil moisture and drought management system monitor soil moisture to lay a certain foundation for the collection of information on water cycle research, agricultural irrigation, rational use of water resources and drought relief work. Doing a good job in soil moisture monitoring, guiding farmers to timely and rational fertilization, irrigating land and fighting drought, disaster prevention, and disaster mitigation have important practical significance for increasing farmers' income. Soil moisture monitoring provides some references for the research and integration of agricultural drought-resistant and water-saving technologies. At the same time, it provides a rich foundation and transformation of results through the exploration and innovation of soil moisture and drought management system information.

Food Additives

Food additives are compounds or natural substances added to food for the purpose of improving the color, aroma, and taste of food, as well as for the needs of anti-corrosion and processing technology. At present, there are 23 categories of food additives, with more than 2,000 varieties, including acidity regulators, anticaking agents, defoamers, antioxidants, bleaching agents, leavening agents, coloring agents, color retention agents, enzyme preparations, and flavor enhancers, nutritional fortifiers, preservatives, Sweeteners, thickeners, spices, etc.
