Introduction: Recently, snowfall has ushered in many places in the north, which has triggered a series of controversies about removing snow from wheat fields. In this topic, we need to look rationally at the effects of snowfall on wheat growth and correct some unscientific views. This article will explain the benefits of snowfall from a scientific point of view, and ** some misconceptions.
Part I: The Benefits of Snowfall and the Meaning of Agricultural Proverbs.
1.Snowfall increases soil moisture: Snowfall can alleviate drought in the field, especially in plots where effective rainfall is lacking, and is beneficial for wheat seedlings to overwinter.
2.Snowfall reduces the number of pests and diseases: Snowfall heralds a cooler temperature, and cold weather can freeze some pathogenic bacteria and eggs, thereby reducing the number of pests and diseases in the field. This also provides favorable conditions for later prevention and control.
3.Snowfall inhibits overgrowth: The arrival of snowfall and cooling will inhibit the upward growth of wheat and avoid overgrowth. However, wheat can still increase root depth and fibrous roots by growing downward, improving stress resistance and lodging resistance.
4.The moral and scientific basis of the agricultural proverb: We are all familiar with the agricultural proverb "wheat covers three layers of quilt, sleep with steamed buns in the coming year" is a metaphor to express the benefits of snowfall on wheat growth. These benefits are based on the impact of snowfall on soil moisture, pest and disease populations, and growth inhibition.
Part II: Misunderstandings and Scientific Analysis.
1.Controversy over snow removal from wheat fields: Recently, there have been some opinions on the Internet about removing snow from wheat fields, arguing that timely snow removal can prevent wheat frost damage. However, this practice is considered unscientific, as clearing the snow deprives the wheat of the benefits of snowfall.
2.Difficulty and feasibility of clearing snow: Snow removal operations require people to clear the snow little by little and pull the snow out of the field, which is impractical in practice. Such a practice was considered to be a layman commanding an insider, and could not be approved by the peasants.
3.Misconception of building greenhouses for wheat: In the past few years, there has also been a view of building greenhouses for wheat to avoid snowfall, cooling and frost damage. However, this practice has problems in terms of cost, wheat growth, etc., and does not conform to the principle of scientific planting.
Part 3: Putting snowfall and scientific planting into perspective.
1.The principle of scientific planting: scientific planting needs to formulate a reasonable planting plan according to the growth characteristics of crops and changes in the natural environment. Winter snowfall has a positive impact on the growth of wheat, and farmers should value and make good use of this natural condition.
2.Rational approach to online views: In the Internet age, there are endless opinions about planting, but we need to maintain a rational and scientific attitude. For those points that do not conform to reality, we should remain calm and not think too much about it.
Conclusion: The impact of snowfall on wheat fields is complex and magical, and scientifically interpreting the benefits of snowfall can help farmers make better use of natural conditions and promote the growth of wheat. At the same time, we also need to maintain a rational attitude towards the online viewpoint, disseminate scientific planting knowledge, and promote the sustainable development of agriculture.
