When you think of "heavy snow", what else can you think of other than snow?From ancient times to the present, there are many proverbs about heavy snow that are related to agriculture, such as "this year's wheat covers three layers of quilts, and the next year sleeps with steamed buns", "half of the snow covers the mountain, and the wheat hits one more stone" and so on.
The ancients also summed up the "three fears of heavy snow" through years of practice, and many rural elderly people still often talk about it until now. There are different opinions on the specific three fears, and the most common one is that the first fear is "afraid of not seeing snow";The second fear is "fear of strong winds";The third fear is "fear of thunder and winter".
Although there are three fears of "heavy snow", there are also many related countermeasures. For example, in the north of our country, for winter wheat and some winter vegetables (garlic, coriander, etc.), if the snowfall or rainfall is not enough, you can water once before or just when the land is frozen, commonly known as "watering frozen water", this method can make the water solidify in the soil, not to lose quickly, and play the role of locking water. "Frozen water" is still being used in combination with sprinkler irrigation technology in recent years.
When it comes to sprinkler irrigation technology, sprinkler heads are indispensable. Printheads are mainly divided into refractive micro-printheads, rotary micro-printheads and atomizing printheads.
The refractive micro sprinkler uses the refraction principle generated by the water flow between the nozzle and the water surface to break up the water flow into a water mist. The refractive micro sprinkler sprays finely, which is suitable for irrigation of agricultural crops such as flowers and vegetables.
The rotating micro-nozzle produces a rotation through the difference in the size of the nozzle and the water pressure, thereby spraying a water mist. The rotary micro sprinkler is suitable for irrigation of fruit trees, greenhouses, nurseries and urban landscaping.
The atomization nozzle mainly sprays pressurized water into the air through the nozzle, and scatters it on the field and crops in the form of a mist. It has the characteristics of low working pressure and high degree of atomization.
The joy of winter is given by heavy snow
Although heavy snow has three fears, as long as we take appropriate countermeasures and management methods, we can make full use of the favorable factors of this season and bring more harvests and benefits to our agricultural production. In this cold season, let's work hard together for our agriculture and ecological environment!
