How many days was the longest period of continuous rain in Shaanxi in history?

Shaanxi encountered the strongest autumn rain weather in 50 years, and the continuous rain ended on the 18th.

The impact of continuous rainy weather on the maturity of autumn grains: Rainy weather results in low average temperatures and insufficient sunshine, which has a certain impact on the maturity of autumn grains. At that time, most of the spring corn and summer corn in Shaanxi Province were in the mature stage. Among them, the spring sown corn in the dry plateau areas of northern Shaanxi, eastern Guanzhong and the shallow hills and hills of southern Shaanxi was in the yellow ripening stage. Some spring sown corn in southern Shaanxi was mature and harvested, and most of the spring sown corn in Guanzhong and southern Shaanxi was in the mature stage. The regional soil is too wet, which has a certain impact on the maturity of summer corn, but the impact is not significant. Generally speaking, the growth and development of corn is normal. Rice is in the maturity stage, and early-maturing rice in southern Shaanxi has begun to be harvested. Potatoes in northern and southern Shaanxi are in the mature stage, and some have begun to be harvested; rapeseed has begun to grow seedlings in southern Shaanxi, and land preparation has begun in Weibei for sowing winter wheat and rapeseed.

Meteorological experts suggest:

1. If there is stagnant water in farmland in Guanzhong and southern Shaanxi, the stagnant water in the field should be drained as soon as possible to ensure the normal maturity of autumn grain crops and prevent crop yield reduction.

2. The soil in most parts of Guanzhong and southern Shaanxi is currently too wet. The harvested farmland needs to be soiled and prepared to maintain the quality of the soil and ensure smooth sowing and emergence of autumn crops.

3. Southern Shaanxi is good at raising rape seedlings.

4. Do a good job in picking leaves and removing diseased plants in the corn field, ensuring ventilation in the field and promoting corn maturity. Fifth, the summer corn in eastern Guanzhong is not expected to mature. It is recommended to harvest it at the right time to use it as silage to ensure that winter wheat is sown in the high-yield period.

Strictly guard against secondary disasters after precipitation. In September, Shaanxi Province had too much precipitation, low temperatures, and saturated soil moisture. Special attention must be paid to preventing local debris flows, landslides and other geological disasters. We should pay close attention to weather changes to prevent the adverse effects of low temperature and continuous rainy weather on agriculture; northern Shaanxi should pay attention to preventing first frost damage to avoid or reduce losses; foggy weather increases in autumn, and heavy fog will bring adverse effects to transportation, human health, etc. Highway and shipping departments must pay special attention to weather changes to ensure traffic safety.

Due to the characteristics of long duration and high intensity of precipitation, the period during the autumn rainstorm and the period after the autumn rainstorm is over are the periods of high incidence of heavy rains, floods and their derivative disasters. Governments at all levels must mobilize The masses should closely monitor disaster-prone areas and quickly organize evacuation of people if abnormal conditions occur; transportation departments should pay close attention to mudslides and collapses on both sides of the road to ensure smooth traffic; large and medium-sized cities should deal with urban waterlogging in a timely manner. Minimize losses caused by natural disasters.
