ExperiencedFarmersI like to use some agricultural proverbs to judge the weather conditions, such as "I am most afraid of Sanjiu warm and dry", "Sanjiu River opens, and the next year will be affected" and so on. Behind these proverbs are rich experience in weather observation and the enlightenment of crop growth patterns. ForFarmersThe weather conditions during the March 9 period directly affect their planting and harvest, so they pay special attention to the observation and development of the weather.
In general, cold weather is not good for the growth of crops. Snow is a natural insulating substance, which can effectively maintain soil temperature when the ground is covered with snow, so that the risk of frost damage to crops is reduced. However, if there are consecutive sunny days, especially if they last for a long time, the melting of the snow will accelerate and the temperature of the soil will rise. As a result, the growth of crops will be affected, and the temperature at which the interior grows will become unstable and susceptible to cold.
In addition, the rapid evaporation rate on a sunny day will cause the soil moisture to evaporate too quickly, and crops need sufficient water to maintain it, so this will also have a certain negative impact on the growth of crops. So,FarmersWe would rather choose colder weather than sunny days, because this is not conducive to the growth and development of crops.
FarmersThe experience of observation and proverbs is not enoughSciencePrecise, but also plausible. In modern timesAgricultureIn production,ScienceThe development of technology has made it:FarmersWe will be able to more accurately determine weather conditions, rationalize farming activities, and reduce the risk of large-scale crop deaths. However,FarmersWeather observation and experience are still of great value, because these experiences are integrated with the wisdom and practice of thousands of years of agricultural civilization, and there are certain laws contained in themScienceBasis.
For example,FarmersThe observed proverbs such as "I am most afraid of the warmth of Sanjiu" and "The river of Sanjiu will be affected by disasters in the coming year" are all summarized based on the adverse effects of continuous sunny days on the growth of crops. ScienceStudies have also found that the sun shines brightly.
Three. During the September and April 9 periods, the snow melt will be accelerated, and the soil temperature will rise, which will affect the growth of crops.
So,Farmersexperience withSciencecan be better guidedAgricultureProduction, to ensure the harvest of farmers and the harvest of grain.
Entering Sanjiu, most parts of our country will usher in extremely cold weather. There are many folk proverbs, such as "I am most afraid of the warmth of Sanjiu", "the snow falls on the three nines, and the four nines freeze to death" and so on, all of which are reflectedFarmersOur experience summary of the observation of the weather in March and the impact on the growth of crops. Sunny days, while pleasant, are not ideal for crop growth, as successive sunny days can cause snow to melt faster and soil moisture to lose moisture quickly, affecting the growth and development of crops.
In modern timesAgricultureIn production,ScienceTechnological advancements for:FarmersWe provide more effective weather tools to better guide the planting and harvesting of crops and reduce the risk of agricultural damage. However,FarmersTheir experiences and observations are still of great value, because they are a summary of the wisdom of their thousands of years of agrarian civilizationScienceside.
