Experts suggest that meteorological arid areas should strengthen the management of wheat fields, and timely check the situation of the situation and seedlings, and carry out classified management according to specific conditions. In the wheat field that has been poured over the winter water, timely remove the compaction by scratching the loose soil so as to facilitate ventilation and increase ground temperature. In areas with irrigation conditions, fine water irrigation or sprinkler irrigation should be performed in sunny afternoons. In regions where there is no irrigation condition or where the weather is cold and it is not suitable for irrigation, measures such as repression, fertilization, and covering straw can be used to ensure drought resistance. For wheat fields with sufficient bottom crops, normal plant growth, or prosperous growth, watering should be postponed, and timely cultivating or repression should be carried out to restrain the overgrowth of the shoots and ensure that the wheat will form strong seedlings safely and overwintering.
In addition, as the temperature continues to fall, the possibility of freezing damage to crops in the field is increasing, and local governments should pay attention to changes in the weather, do a good job in wheat field coverage of anti-freezing work, do a good job of supporting the gully system, and ensure that the gullies are connected.
In early January, the weather in the province was fine, the temperature was low, and the precipitation was less, which was conducive to the growth of wheat and rape. The situation of poor early seedlings was improved. However, the drought still affects the growth of wheat and rape in our province. According to the calculation results of the agricultural drought index of the Meteorological Observatory of Jiangsu Province, the soil water deficit is found in the area south of the Huaihe River, and the drought occurrence in the Huaibei region is expanding. According to the medium-term weather forecast released by the Central Meteorological Observatory on January 15, there will be no precipitation in Huanghuai and other places in the next 10 days, and drought conditions in the meteorological drought areas will continue to develop. In the Huaibei region, we must continue to do a good job of drought relief in farmland and timely irrigation to ensure the normal growth of wheat and rapeseed.
