In the first half of June, the temperature in the Beijing area was high, most of the precipitation was less, and the sunshine was less. The light and temperature conditions in the ten-day period are conducive to the normal grain filling of winter wheat and the growth of vegetables in the open field and protected areas; however, the soil moisture is poor, resulting in slow growth of spring maize. It is expected that there will be no large precipitation in the middle of the year, which is conducive to wheat harvesting. However, due to the continuous decrease of precipitation, soil moisture is not conducive to the sowing of summer corn.
Due to the high temperature in the plain wheat area in early June, there is no obvious dry hot wind weather, and the temperature difference between day and night is large, which is conducive to the normal grain filling of winter wheat. However, the lack of precipitation has a certain adverse effect on the rapid grouting of winter wheat with insufficient moisture. Since May, the precipitation has been less, the soil moisture is insufficient, and it is not good for summer corn planting. It should be planted or planted and then poured into the head water.
At present, spring maize in the mountains has entered the seven-leaf stage. Most of the plots have poor soil moisture and slow growth of corn seedlings. Water and fertilizer management for field crops such as spring maize should be strengthened.
At present, meteorological conditions are favorable for the growth of vegetables in open fields and protected areas. As the temperature rises and precipitation increases, close attention should be paid to the occurrence and development of pests and diseases, so that timely release of wind, cooling and dehumidification, and timely prevention and control of pests and diseases. At present, tomatoes, cucumbers, beans and other vegetables in the protected area are in the picking season, and some exposed cucumbers and beans are also picked.
According to the forecast of the Beijing Meteorological Observatory, it is expected that there will be three rainfall weather processes in mid-June. The average temperature in the plain area of ​​the city is around 25 °C (average 24.7 °C). The extreme maximum temperature is 32 °C. The precipitation in most areas is around 20 mm (23.5 mm per year). The main weather process is there. From June 11th to June 12th, there were thunderstorms in the northern region; showers around June 16th; June 18th to June 19th, moderate rain.
