What time period does the long summer refer to?
Long summer usually refers to the last month of summer, that is, July in the solar calendar. This month, the temperature is high, the humidity is high and the rain is abundant. Long summer is the hottest period of the year in many areas, and it is also a period of vigorous crop growth. High temperature and sufficient water are helpful to the growth and development of crops, but they also bring challenges to agricultural management.
Because the environment with high temperature and humidity is easy to breed various diseases and insect pests, such as rice blast and rice planthopper, it is necessary to strengthen the management and protection of farmland and take timely measures such as irrigation, drainage and fertilization to ensure the healthy growth and bumper harvest of crops.
In addition, the long summer is also a good time for people to have fun, get together and communicate. People can make full use of this time to do outdoor activities, such as picnics and swimming, to relax themselves. The long summer time in different areas may be slightly different. In some areas, the climate changes greatly, and the specific time of long summer will change accordingly. So the specific time needs to be determined according to the local climate.
The influence of long summer climate characteristics on agriculture;
1. Effect of crop growth: High temperature and sufficient sunshine in the long summer season are beneficial to crop photosynthesis and nutrient accumulation, and promote crop growth and development. For some crops that need high temperature and sufficient sunshine, such as rice and corn, the climatic conditions in long summer are very favorable, which can improve the yield and quality of crops.
2. Effects of pests and diseases: The environment with high temperature and high humidity is prone to breed various pests and diseases, such as rice blast and rice planthopper, which cause serious harm to crops and affect their quality and yield. Therefore, agricultural management departments and farmers need to strengthen the monitoring and prevention of pests and diseases, and take effective measures to control the spread and spread of pests and diseases.
3. Impact of agricultural management requirements: In the long summer, high temperature and high humidity make crops grow rapidly, which easily leads to various physiological problems, such as drought and heat damage. Therefore, it is necessary to strengthen the management and protection of farmland and take timely measures such as irrigation, drainage and fertilization to ensure the healthy growth and bumper harvest of crops. At the same time, it is also necessary to adjust the agricultural planting structure and management methods in time according to climate change to adapt to the impact of climate change on agriculture.
