In the absence of rainfall, soil water content measured by the real-time soil moisture monitoring system suddenly increased and there was a violation of the convention. This was due to the fact that the wheat was in the period of turning green - jointing, and the irrigation area had to carry out spring irrigation for wheat during this period. In the absence of rainfall, according to the law of soil water regression, actual measured values ​​are obviously small, which may be caused by observation errors. In general, the calculated results of the model are in good agreement with the measured values.
In actual soil water retreat, there will be almost no occurrence of regression of moisture in the surface soil to zero but no subsidence in the underlying soil. The reason is simple, the upper and lower layers in the soil are connected, due to the water potential in the soil. The role of soil moisture in the soil with the upper and lower layers of the water potential changes at any time. The real-time monitoring system for soil moisture found that the change is: In general, when the upper soil moisture subsides to a certain extent, the underlying soil moisture will disappear together.
Regional soil moisture is an important factor in many factors of agricultural hydrology. At the same time, the real-time monitoring system of soil moisture is a basic work for farmland water management and regional water resources management. It is a reasonable implementation of irrigation drainage, the increase of crop yields, and water conservation. The analysis of the transformation relationship of four waters and the improvement of the utilization of water resources all play an important role. In recent years, soil moisture content research has become a hot spot in agricultural and water conservancy at home and abroad, and many methods of public opinion forecasting have been proposed. However, the direct monitoring of soil moisture content real-time monitoring system in agricultural products is currently used.
Artificial Grass For Football Field
An artificial turf field is a football playing field that uses artificial turf. Artificial turf football fields usually use turf made of synthetic fiber materials, which have good elasticity and wear resistance to better protect the safety of players. Artificial turf fields have a longer lifespan than natural turf, are easier to maintain and can be used in all weather conditions. In addition, artificial turf fields can also change the bounce and speed of the ball by adjusting the hardness and friction of the grass, improving the game's ornamental and competitive. As a result, artificial turf fields have been widely used in modern football matches.
MCG Industry Group was founded in 2019.We are a professional supplier of artificial turf and a wholly owned holding company of Jiangsu MCG Industrial Development Company. Jiangsu MCG Industrial Development Company has one artificial grass production base to meet the greatest needs of customers. After years of brand accumulation, MCG Industry Group gathered a group of practical spirit, theory and practical experience of professional marketing team, providing site construction, maintenance and maintenance services and other series of solutions.
