土壤中的水分用于供给植物生长，土壤的含水量和含盐量会直接影响植物生长，含量直接影响作物对养分的吸收速率，土壤中有机养分的分解矿化离不开水分，施入土壤中的化学肥料只有在水中才能溶解，养分离子向根系表面迁移以及作物根系对养分的吸收都必须通过水分介质来实现，所以土壤水过多或是过少都会影响植物的生长，土壤的含盐量过高会使植物内部渗透压过大造成植物的死亡，土壤的含盐量过低会使植物无法吸收足量的有机离子，因此对土壤的不同土层的含水量和含盐量的监测是非常重要的。通过对土壤内含水量和含盐量的实时监测，并以此为指标，可以指导农业灌溉、农业种植、植被保护等。The water in the soil is used to supply the growth of plants. The water content and salt content of the soil will directly affect the growth of plants, and the content directly affects the absorption rate of nutrients by crops. The decomposition and mineralization of organic nutrients in the soil cannot be separated from water. The chemical fertilizers can only be dissolved in water. The migration of nutrient ions to the root surface and the absorption of nutrients by crop roots must be achieved through the water medium. Therefore, too much or too little soil water will affect the growth of plants. The salt content of the soil If the amount is too high, the osmotic pressure inside the plant will be too large, causing the death of the plant. If the salt content of the soil is too low, the plant will not be able to absorb a sufficient amount of organic ions. is very important. Through the real-time monitoring of soil water content and salt content, and using this as an indicator, it can guide agricultural irrigation, agricultural planting, and vegetation protection.
现有技术中，土壤水分盐度的检测方法多采用遥感技术预测土壤含水量和盐度，通过在土壤表面监测地表水的含量、盐分来预测土壤内水分含量和盐度，同时大部分监测土壤水分、盐度的仪器过于笨重，不便于携带。且不同地理位置、同一个地理位置的不同区域的水分盐度均不相同，在农业灌溉、农业种植、植被保护中，需要因地适宜进行灌溉和种植，只是单纯地检测并不能满足作业需求。In the prior art, the detection methods of soil water salinity mostly use remote sensing technology to predict soil water content and salinity, and predict soil water content and salinity by monitoring the surface water content and salinity on the soil surface. Instruments for moisture and salinity are too bulky and inconvenient to carry. In addition, the water salinity of different geographical locations and different regions of the same geographical location is different. In agricultural irrigation, agricultural planting, and vegetation protection, it is necessary to carry out irrigation and planting according to the location, but simple detection cannot meet the operational needs.
