At the beginning of the small summer, the Meiyu in the Jianghuai River Basin has ended. The southeastern part of the Huaihe River and the Qinling Mountains in the eastern part of China has started the southeast monsoon rainy season from the Pacific Ocean. The precipitation has increased significantly and the rainfall is relatively concentrated. South China, Southwest China and the Qinghai-Tibet Plateau are also from the Indian Ocean and China. In the southwestern monsoon rainy season of the South China Sea, the middle and lower reaches of the Yangtze River are generally high temperature and low rainfall under the control of the subtropical high. The frequent occurrence of drought has a great impact on agricultural production, and it is very important to store water and drought. The farmer said: "The rain in the sky, the rice in the pot", the thunderstorms that occur at this time, the precipitation caused by tropical storms or typhoons are very beneficial to the growth of rice and other crops, but sometimes they also give dry crops such as cotton and soybeans. Vegetables have an adverse effect. In some years, the cold air force in the north is still strong before and after the summer heat. In the middle and lower reaches of the Yangtze River, the warm air in the south is evenly matched, and there is a frontal thunderstorm. “Small heat is a thunder, and it is reversed to make Huangmei.†The thunderstorm in the summer heat season is often the weather information of “pour Huangmeiâ€. The rainband will also remain in the middle and lower reaches of the Yangtze River for a period of time. The average temperature in the southern part of the country is about 26 °C, which is already very hot in summer, but it has not yet reached the hottest time. In mid-July, in the low-altitude valleys of southeastern China, the daily average temperature is higher than 30 °C, and the daily maximum temperature is higher than 35 °C. This is unfavorable for hybrid rice. In addition to the fact that this factor should be fully considered in the layout, the corresponding remedial measures should be taken. In the northern part of the northwestern plateau, frost and snow are still visible at this time, which is equivalent to the early spring of South China. During the summer heat season, the western part of southern China has entered the most rainy season. The number of rainstorm days in July and August can account for more than 75% of the whole year, usually about 3 days. In places where the terrain is undulating, there are often flash floods and even mudslides. However, in the eastern part of South China, after the summer heat, it was often controlled by the subtropical high, and it was more and more sunny and hot weather, and began to enter the drought period. The climatic characteristics of this eastern arid sorghum in most parts of southern China have a great relationship with agricultural abundance. It is necessary to adopt drought and flood control measures as soon as possible to minimize the damage. As well as paying attention to the disaster caused by thunderstorms, thunderstorms are often accompanied by strong winds and heavy rains. Sometimes there are hailstones that are prone to disasters.

Small summer weather conditions and farming activities
Before and after the summer, in addition to harvesting winter and spring wheat crops in the northeast and northwest regions, agricultural production is mainly busy in field management. Early rice is in the late filling stage, and early-maturing varieties must mature before harvesting, and the fields should be kept dry and wet. The mid-season rice has been jointed and entered the booting stage, and the panicle fertilizer should be applied according to the growth trend. The single-season late rice is being divided, and the tiller should be applied as soon as possible. Double night seedlings should be controlled to control pests and diseases, and they should be given “send marriage fertilizer†5-7 days before planting. “The heat in the small summer is hot, and the cotton pruning does not stop.†Most of the cotton in the cotton area begins to flower and ring, and the growth is most vigorous. In the process of reapplying the flower and bell fertilizer, it is necessary to pruning, smashing and removing the old leaves in time to coordinate the nutrient distribution in the plant. It enhances ventilation and light transmission, improves group microclimate and reduces bud ringing. High temperature in summer is a season in which a variety of pests such as aphids and spider mites bloom. Controlling pests and diseases in a timely manner is another important link in field management. â€
