In late August, the temperature in Tianjin was slightly higher than that in normal years. The precipitation was generally lower than normal, but the precipitation in the eastern Ninghe was more than that in the east. The high temperature and high humidity in the first day were mainly affected by the foggy weather, the sunshine deviation and the soil moisture conditions were suitable. Crop growth is normal, but meteorological conditions increase the likelihood of pests and diseases.
At present, local summer maize has entered the pollination and grain filling period, and the development period is slightly later than normal. The temperature is suitable and the air humidity is high, which is good for the pollen to maintain vitality. However, the lack of sunshine conditions limits the photosynthetic rate of the crop to a certain extent, and the temperature difference between day and night is insufficient, which is not conducive to dry matter accumulation and may affect grain formation. The soil moisture condition is better, which provides a sufficient water supply for the corn filling period.
Local cotton is in the boll opening period. The boll opening period requires sunny, breeze, and relative humidity, and the suitable temperature is 20~25°C. The high temperature, high humidity and low sunshine conditions in late August are not conducive to cotton bolls, and the quality of cotton wool is also affected, and the high temperature and high humidity conditions increase the possibility of pests and diseases. Spring corn is in the late filling stage. Meteorological conditions are generally beneficial to spring corn grouting, but the air humidity is relatively high, which may be detrimental to the waxy ripening of mature kernels. Rice is in the heading stage, and the temperature conditions are conducive to rice filling.
