Description
Technical Field
The utility model relates to an agricultural equipment's technical field especially relates to a winter wheat spring frost damage early warning and monitoring devices.
Background
Worldwide, spring frost is one of the important meteorological disasters affecting the normal growth of wheat. In Huang-Huai-winter wheat areas in China, radiation type frost and mixed type frost frequently occur in spring, and the phenomenon of short-time large-scale cooling is often caused. When wheat enters the joints, if the temperature of the plants is reduced to below the freezing point, young ears are obviously damaged, and the yield is reduced. The annual identification data of meteorological disaster statistics in recent 30 years show that the occurrence frequency, the disaster area and the disaster area of the frost damage of the wheat are in an aggravation trend, and the risk of the yield loss of the wheat is increased.
On the field scale, the lowest plant temperature is considered as the best index for quickly judging the frost damage of the wheat, but a special temperature sensing probe is required to be inserted into a wheat leaf or a wheat stem for measurement, the operation is complex and the data stability is poor. Therefore, the lowest temperature is often used to replace the lowest plant temperature to judge frost damage of wheat after jointing. The temperature of the louver box, the temperature of the canopy and the temperature of the grass surface can be divided according to the difference between the vertical height of the measured temperature and the environment of the underlying surface. The lowest canopy temperature is closest to the lowest plant temperature, but occurs at a variable height, typically in the range of 10-20cm below the canopy, and this range increases with increasing wheat plant height. Therefore, the layout of the air temperature sensor is complicated due to the height change of the lowest canopy temperature on the vertical section, and the height of the air temperature sensor is continuously adjusted according to the plant height change. The lowest grass surface temperature is another effective and stable freeze injury index close to the lowest plant temperature, but the practical application of the grass surface temperature sensor in the wheat field is limited due to the fact that the grass surface temperature sensor is arranged in the field, the requirement on the ambient environment condition is high, and the maintenance cost is high. Therefore, in the current field automated weather observation service, the recorded conventional meteorological element is the lowest louvre temperature. However, the lowest louver box temperature is greatly affected by other meteorological factors and soil environment factors, and the judgment accuracy of frost damage particularly when the change of humidity and the like is large faces a great uncertainty. With the improvement of the performance of the infrared thermal imaging camera and the continuous reduction of the cost, a high-precision full image surface temperature distribution diagram can be obtained in real time, and great superiority is shown in the temperature measurement of crop leaves, stems and the like, so that the infrared thermal imaging camera serving as indispensable equipment is widely applied to high-throughput table type information acquisition and water stress state monitoring of various crops. The lowest plant temperature measured by the infrared thermal imaging camera is used for replacing the lowest plant temperature measured by the traditional method, so that the convenience and the precision of real-time diagnosis of the frost damage of the wheat are greatly improved.
The occurrence of frost damage in spring has uniqueness, and is mainly reflected in four aspects: (1) Usually occurs from wheat jointing to flowering, once or more; (2) The temperature reduction process is not more than several hours, and the lowest temperature is between 8 o 'clock at night and 8 o' clock at morning; (3) Along with the development process, the frost damage degree of the wheat is in an aggravation trend; (4) The symptom of freezing injury of young ears or leaves generally occurs about one week after freezing. At present, a related device specially aiming at wheat frost damage monitoring is not mature, and a device carrying an infrared thermal imaging camera cannot meet the purposes of intelligent early warning and monitoring of frost damage. Therefore, the device capable of being used for intelligent early warning and monitoring of frost damage is developed, and the device has obvious practical value for timely carrying out emergency prevention of frost damage, implementing field management after freezing and the like.
