Introduction: The first day of the seventh lunar month is one of the traditional folk festivals. The weather conditions on this day have a significant impact on the agricultural harvest. There is a folk proverb: "If it rains on the first day, it must be a year of disaster." "So, what is the sign of rain on a sunny day in the first day of July?
Weather conditions on the first day of July
1. The reason for the rain on a sunny day
On the first day of the seventh lunar month, sunny days and rain are usually caused by the convergence of warm and cold airflows. When warm and moist air currents meet dry and cold air, precipitation is prone to occur. This weather phenomenon usually brings abundant precipitation, which is beneficial for the growth of crops.
2. A sign of rain on a sunny day
As the folk saying goes, "If it rains on the first day, it must be a disaster year", meaning that a rainy day in early July may lead to a reduction in agricultural production. However, modern science believes that the relationship between sunny days and agricultural harvests is not absolute. Moderate precipitation helps alleviate drought conditions and is good for crop growth.
The impact of rain on agriculture on a sunny day
1. Alleviate drought
In the case of a prolonged drought, moderate precipitation can alleviate the drought and provide sufficient moisture for crops. This helps the crops to grow and increase yields.
2. Promote crop growth
Rain on a sunny day can increase the moisture of the soil, which is beneficial for the growth of crop roots. In addition, moderate precipitation can also wash away dust from the leaves, improving the efficiency of photosynthesis, which in turn promotes the growth of crops.
3. Prevent pests and diseases
Moderate precipitation can reduce the incidence of pests and diseases. Rain washes away pests and eggs, reducing the spread of pests and diseases, thus ensuring crop yields.
Although there is a folk proverb that "if it rains on the first day, it must be a disaster year", in reality, the impact of rain on agricultural harvests on sunny days is not absolute. Moderate precipitation can help alleviate drought, promote crop growth, and prevent pests and diseases. Therefore, a sunny day on the first day of July is not necessarily a bad thing, on the contrary, it may be a harbinger of a good harvest year.
