Cold damage in wheat fields, want to fill the water with available chemical fertilizers, promote the small tiller and the new spike of delivery, cold damage caused by the damage to a minimum. In spring windy weather, real-time soil moisture monitoring system analysis found that after the wind soil loss is faster, weeding and weeding should be timely, eliminating hardening and loose soil, temperature to maintain moisture.
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. Through the real-time monitoring system of soil moisture, timely detection of the large population before the winter and the strong tendency of the wheat field after the beginning of spring can take deep cultivating and cutting off the roots and repression during the rejuvenation and jointing. Water-free conditions of dryland wheat fields, spring soil remediation in time after the decompression, lifting and maintenance, and drought protection seedlings.
The growth period of wheat is long, and the climate during growth is variable. Especially after entering the returning green period, cold air activities are generally frequent in different degrees. Late spring occurs frequently, and the temperature fluctuations are large, often causing adverse effects on wheat growth. Therefore, we must pay close attention to weather forecasting and do a good job in defense of late frost. Irrigation was conducted in time before the onset of the cold current (moderate irrigation volume). The real-time soil moisture monitoring system after the cold flow was used to timely check soil moisture conditions.
Soil moisture real-time monitoring system analyzes water at different seedling stages
Appropriate soil moisture is a necessary condition for the growth of crops to ensure the normal order of winter wheat growth. The winter wheat growth period in Henan Province is relatively long. Through the real-time soil moisture monitoring system, accurately grasping the soil moisture conditions at the sowing time of the green crops, formulating scientific irrigation and The basic measures of fertilization, after strengthening the key winter wheat growing period, are of great significance to the improvement of the utilization rate of cultivated land resources, high quality and high yield wheat.
