Soil moisture is a key indicator in agricultural production. It plays a crucial role in the growth of crops. Effective measurement and control of soil moisture content is the basis of modern agricultural production, and it is also an effective measure to promote agricultural production and increase income. However, we know that the soil has a certain depth and level, and the soil moisture changes at different levels have a good correlation, and the impact on the growth of crops is a comprehensive effect. Therefore, in order to more scientifically carry out irrigation, ensure that crops thrive, It is simply not enough to know the moisture content of the soil surface. It is also necessary to use a soil profile moisture meter to simultaneously measure the soil moisture content at different levels of the soil. In terms of crop growth, the depth of water absorption at different periods is also different. For example, the crop sowing depth is about 5cm, and the water content of 0~10cm soil layer directly affects the germination and emergence of seeds; the crop root system is shallow at the seedling stage. Water relies on ploughing the soil supply; in the middle and late period, although some of the roots are tied deeper, they can absorb the moisture of deeper soil layers. When the soil moisture is insufficient, the first thing that affects the absorption of surface water is the plant. Therefore, in order to provide comprehensive protection for crops during the whole process of crop growth, it is necessary to use the soil profile moisture velocity measurement instrument to accurately understand the soil moisture content at different levels of the soil profile, so as to formulate scientific and reasonable irrigation measures. management. In fact, with the development of science and technology, agricultural production management has become more and more detailed and more scientific. The use of scientific instruments, such as soil profile moisture meter, to carry out soil environment-related data monitoring not only provides a basis for ascertaining the relationship between crops and soil moisture, but also rationally allocates agricultural resources and promotes crop protection. The level of planting has laid the foundation for the development of high-efficiency agriculture and ecological agriculture. Nantong Kezheng Packing Co.,ltd , https://www.ntdazhengplastic.com
