Appropriate lyrical condition is a necessary condition for ensuring the normal growth of winter wheat. Henan Province has a long growing period of winter wheat. Therefore, real-time soil moisture monitoring system can accurately determine the status of soil moisture in wheat fields sown to returning green, formulate scientific irrigation and fertilizer measures, and strengthen wheat. The management of water and fertilizer in the key growth period after winter is of great significance for improving the utilization of farmland resources and realizing the high quality and high yield of wheat.
Cultivated and repressed wheat fields in spring can practise soil, seal cracks, keep warm, promote root growth, strengthen drought resistance and freeze resistance, and promote stable growth of wheat seedlings. For the pre-winter group is too large, after the spring has a long trend of wheat, go green to jointing period can take deep cultivating root, repression, control prosperous. Water-irrigated dryland wheat fields, timely repression and recultivation after soil defrosting in the spring, raising the soil moisture, protecting the drought and protecting the seedlings; timely detection of the soil moisture content real-time monitoring system.
In actual production, the growth cycle of wheat is relatively long, and the weather is changeable. Especially during the period of returning to the green, the cold air frequently fluctuates to a greater degree in pollen and temperature, which often has an adverse effect on wheat growth. Therefore, we should pay close attention to the weather forecast and do a good night defense. The real-time monitoring system of soil moisture content is the key to timely detection of waterlogging conditions. The arrival of cold currents (in irrigation water) is promptly irrigated. During the cold spell-checking time, freeze damage occurs for wheat, and the water is filled with available chemical fertilizers to promote small tillers and tillers into a new ear. Loss caused by cold damage is reduced. To the lowest.
