What impact will the strongest rainfall in the south bring since the flood season?

This season happens to be the season of crop growth, so it is necessary to use sunlight for photosynthesis. However, in heavy rain and gloomy weather, crops can't get enough sunshine, so they can't grow normally. If they miss this growth opportunity, the output of crops will definitely be limited, which is undoubtedly a huge disaster for farmers who work hard in the countryside! Rainstorm weather is bound to cause floods! In the face of natural disasters, everything in the world seems so insignificant! There will definitely be a lot of sand accumulation and collapse in the field!

Normal agriculture and animal husbandry grow cool, rainy and sunny. Less rain leads to drought, more rain leads to waterlogging, and heavy precipitation is more harmful. With the continuous precipitation, the soil moisture in the field is always saturated, which makes the growth and development of green plants slower and slower, and even the root system cracks or the whole plant dies. In particular, root crops, such as potatoes, ginger slices, sweet potatoes, or watermelons, are very harmful to commercialization if they are soaked in water for a long time, and a large area of fruit rot will occur in the later stage. In terms of pests and diseases, precipitation has increased, and the field has been in high and low temperature standards for a long time. There are pests and diseases in fields with high temperature and humidity, high and low temperature under normal pressure, ultra-low temperature and high and low temperature, which shows that high humidity will cause pests and diseases in other cases, especially in the case of showers, and the prevalence rate is higher in Chuqing.

At the level of pests and diseases, high environmental humidity is conducive to the breeding of pests and diseases, and some insects will be transferred on a large scale due to cyclones, which will have a great impact on crop growth. Too much precipitation is very harmful to agriculture. Crops that are harmful, such as coconut shoes and natural rubber, have high requirements on calorific value and are only planted in the subtropical zone; Cabbage in Xiqingling is only planted in the middle temperate zone; If there is too much precipitation in spring, the temperature is too low, and the growth of wheat is slow, the seedlings will be stiff. When wheat matures in early summer, if it encounters continuous rain, it will lodging and continue to sprout. Germinated wheat is inedible and can only be used as concentrated feed. The damage to farmers is very great. Too much precipitation in autumn will aggravate the pests and diseases of some autumn crops.

The ripening system that harms crops is short in the continuous high temperature season in the northeast plain of China, and crops are only harvested once a year. In the Pearl River Delta of China, the calorific value is rich, and rice can be harvested three times a year; It is the sowing season that harms crops. For example, in China's tropical temperate climate, the temperature is not easy to be very low in winter, and wheat can spend the winter. Winter wheat can be planted in this area. The winter in Sanjiang Plain is very cold, and only spring wheat is planted. Rivers and hillsides are vulnerable to natural disasters. If there is a flood disaster, the rainfall will immediately become a flood, and all crops will be washed away and destroyed by the rain. That will do great harm to the hard-working farmers, immediately lead to a bumper harvest for the villagers, indirectly damage the farmers' income and the national grain price, and make the crop price unstable. Heavy rains often lead to floods, which cause a large amount of fine sand in the soil to flow out and destroy the soil texture and fertilizer efficiency.
