After the drought is relieved, it is necessary to prevent the wheat from being "four evils"
Under the influence of factors such as drought-resistant watering and artificial precipitation, the drought in Huaibei District of Jiangsu Province has been greatly alleviated. However, agricultural experts have warned that as the temperature rises and rainfall increases, wheat spring waterlogging, grass damage and disease. The threat of “three evils†and “cold spring cold†will gradually increase.
In this regard, agricultural experts suggest that the rice stalks in the Huainan area should be cleared of the field ditch as early as possible, and the water in the field should be eliminated in time. Recently, the temperature has risen remarkably, and the weeds in the field have begun to germinate a lot. Before the wheat jointing, the cold tail warm head should be seized to help the weather, select the right medicine, and remove the medicine. In the case of cold spring, for wheat fields with a freezing death rate of 10 to 30%, urea can be applied for about 5 kg per mu, and wheat fields with a freezing death rate exceeding 30% are incremented by 10 percentage points, and urea is applied for 2 to 3 kg per mu. The maximum is no more than 15 kg.
