Recently, the weather has been unusually hot, and the hot weather makes people feel a little suffocated. And just when people were expecting a cooling rain, the sudden heavy rainfall brought some troubles to people's lives. The abnormal change of weather not only brings a certain inconvenience to people's travel, but also has a certain impact on agricultural production. Especially at this time, when it is the growing season for crops, the impact of changes in temperature and rainfall on agricultural production is particularly important. So, in the context of the current frequent meteorological changes, how should we view the impact of such weather changes on agricultural production? And how can we deal with the challenges posed by this changing weather?
The weather was unusual, and the heat was coming
Recently, under the influence of warm and humid airflow and the western Pacific subtropical high, a rare high temperature weather process has occurred in the eastern country. Among them, the high temperature weather is mainly concentrated in Jiangsu, Zhejiang, Shanghai and Xinjiang, and the temperature in some areas even exceeded 41.9 °C, breaking the historical extreme. Such hot weather not only makes people feel unbearable, but also has a certain impact on agricultural production. On the one hand, continuous high temperature weather can easily lead to the rapid evaporation of soil moisture, which brings certain difficulties to the growth and irrigation of crops. On the other hand, long-term high temperature weather is also easy to cause crops to wither and yellow, thereby affecting the normal growth and development of crops. It can be said that the high temperature weather has brought certain pressure to agricultural production and also brought a certain impact on the production and life of farmers.
Sudden heavy rainfall
And just when people were expecting a cooling rain, a wave of heavy rainfall suddenly hit, bringing some troubles to people's lives. According to the forecast of the meteorological department, this heavy rainfall will mainly affect North China and Northwest China, and the rainy weather will continue for a period of time due to the influence of the west wind. Among them, the rainfall in Inner Mongolia, Gansu and other places even reached 100~168 mm, and there was a weather process of moderate to heavy rain or even heavy rain. Such heavy rainfall will also have a certain impact on agricultural production. On the one hand, excessive rainfall can easily cause water accumulation in farmland and affect the normal growth of crops. On the other hand, heavy rainfall can also easily lead to the lodging of crops and even the problem of continuous cropping of rice, which brings certain losses to agricultural production.
The impact of weather changes on agricultural production
It can be seen that the current weather is unusually hot, and the weather process of high temperature and heavy rainfall will continue for a period of time, and the impact of such weather changes on agricultural production is very large. On the one hand, the continuous high temperature is easy to affect the growth and development of crops, and it is also easy to induce crop diseases and pests. On the other hand, the sudden heavy rainfall will also have a certain impact on agricultural production, especially for the growth of crops in some wet seasons. It can be said that the current weather changes are both a challenge and a test for agricultural production.
How to deal with the challenges posed by changing weather
How should we respond to the challenges posed by the current climate change? For high temperature weather, we can ensure that crops have sufficient water supply through reasonable irrigation measures; It is also possible to reduce the direct exposure of crops from high temperatures by reinforcing the shade nets of the farmland. Timely harvesting is also very important to effectively avoid the adverse effects of high temperature weather on the growth and development of crops. For heavy rainfall weather, we can remove the stagnant water in the farmland in time through reasonable drainage measures; Some rice-resistant varieties can also be selected to effectively mitigate the impact of heavy rainfall on crops.
