In the middle of the night, the temperature dropped even lower, and the adults in the village became sad. If this trend continues, you may be able to see the frost when you wake up tomorrow.

Some unwilling villagers moved the rice stalks to the vegetable field overnight and spread a layer on top of the vegetables. If it were really frosty, it wouldn't be all broken.

"Almost all of our family can be harvested, let's cut it all tomorrow! Those vegetable seedlings have to be kept insulated. The second uncle spoke.

Because of Chu Jiaqiang's advice, they didn't plant much, so they were not as anxious as others. After staying for a while, he also went out with Chu Jiaqiang and laid straw for the vegetable seedlings in the two fields.

Frost is a phenomenon of condensation of water vapor at very low temperatures, similar to snow. In a southerly place like Chujiazhai, it is impossible to see snow, so the only thing children can look forward to is frost.

In the early morning of the harsh winter, frost usually forms on outdoor plants, because the plants dissipate heat slowly at night, the surface temperature is very low, the water vapor does not disperse quickly, and it freezes when it gathers on the surface of the plants, so frost is formed.

"There shouldn't be frost tonight, and if the temperature continues to drop tomorrow, it's likely." Chu Jiaqiang guessed.

Here in their Chujia Village, there is a huge "temperature regulating machine" of Yunkai Mountain, which will not cause too much temperature difference over the years. Temperature changes tend to be much smaller than elsewhere.

Everyone has read today's news report that many places in the south have begun to freeze. Although everyone was on guard under the reminder of zhèngfǔ, it still caused a lot of damage, forming an ice disaster that occurs once in ten years.

Ice disasters are more severe than frosts, and they can be very harmful to power grids, transportation, and crops. The harm to the power supply network, because the freezing rain falls on the power line to form solid ice, the power supply network can not bear the weight of icicles, resulting in damage; For the hazards of transportation, traffic accidents will occur due to icy roads; For crops, it can cause severe frost disasters and so on.

"It's hard to say! It's not like we've never frozen here before. Even if there is no frost tonight, according to the weather forecast, the temperature will definitely drop tomorrow, and tomorrow night will definitely be inevitable. The second uncle said a little worriedly.

He is not worried about his own family, but about other villagers. Now, the family doesn't worry about that loss at all.

"Tomorrow we will have enough frost protection measures." Chu Jiaqiang said.

Vegetable frost prevention is nothing more than those few measures, and it is not difficult to implement. Cover straw, straw and mulch before frost comes. Watering the day before the frost comes. Stable ground temperature to prevent frost. Before the frost occurs, spray water on the surface of the plant, which also has a frost-proof effect, or smoke to form a smoke screen to prevent frost damage, the smoke should not be too early, it should be small and uniform, and the smoke pile should be evenly distributed.

Some people may wonder: isn't watering before frost more prone to frost? After all, frost is made of water. In fact, anyone who has read the book knows that the heat capacity of water is very large, and water freezing needs to release a large amount of heat energy, which can slow down the rate of low temperature decline on the bottom surface.

The next time they got up, everyone breathed a sigh of relief, and sure enough, as Chu Jiaqiang said, although the temperature was lower than yesterday, it had not yet reached the level of frost.

Early in the morning, even the monkeys cowered in their nests and refused to come out, the little squirrels also hugged their big furry tails to keep warm, and the little golden couple ran to the kitchen to keep warm. Only the big tigers, bears and ferrets didn't pay attention to the cold. Especially for snow sculptures, people naturally like the cold region covered by thousands of miles, and this temperature makes it feel even more friendly.

Today, everyone will be very busy, as long as the vegetables that can be harvested a little, everyone will not hesitate to cut them and sell them, saving themselves from worrying all day long.

"It looks like we're going to be here for a while, and the road north has been frozen over." A tourist from the north spoke. Although the temperature in Chujiazhai is not low today, it is nothing to him, it is said that it is already more than ten degrees below zero, and it can freeze in one breath.

"Then stay here for a while! Anyway, when you go back at this time, you won't have much to do. Just make a few more phone calls and go back to say hello. The old village chief said.

Chu Jiaqiang's father-in-law, Mayor Ye, hurried back to the town after breakfast, and at this time, their team also had a lot of things to do, especially at the critical moment of the development of Heqian Town, and they couldn't relax.

Vegetable buyers are also seizing the time and buying on a large scale. This year, the temperature dropped suddenly and quickly, and many people were caught off guard. Therefore, vegetables will be in short supply in the near future, and the price will fluctuate greatly. In the north, except for those cultivated in greenhouses, it is impossible to find the shadow of vegetables in the wild.

Quickly finished harvesting his family, and after weighing, Chu Jiaqiang and the others went over to help whoever was busy. Rural people are very good at this, whoever is in difficulty, as long as there is no hatred, almost all will come forward to help, which is more humane.

"Fortunately, the price has risen, and although the output is not high, it has basically made up for it." This villager grows a lot of vegetables, and if it really snows, the loss will be quite large. They had cut down all the fruit trees, so now they are pinning their hopes on vegetables.

After a busy day, the originally green farmland has become bare. The trucks carrying vegetables are almost lined up to drive out, which is very spectacular.

"It seems that it is a bit difficult to eat vegetables in the past month or two." Liang Yu said. Seeing that the whole field was cleared, anyone would have this idea.

Fortunately, almost every household in the countryside prepares dried vegetables, kimchi and the like. These were originally used for porridge, but at this time, they can only be substituted!

"It's okay, this kind of cold air, we won't last long, as long as it's a little warmer, we can plant it again, at most it will grow a little slower." The second uncle smiled.

"Plant bean sprouts tomorrow, plus those four seasons melons, so that everyone will not eat dry food." The second aunt also spoke.

The sprouts in the countryside are easy to cultivate, because they don't need sunlight, so just spread a layer of sand on the ground, sprinkle some fertilizer, sprinkle the soybeans down, and then cover a large wooden cabinet on it, and it can be harvested in a few days.

Four seasons melon is the name of Chujiazhai, that kind of melon is not big, but it can bloom and bear melons all year round, not afraid of cold, so it is called four seasons melon.

At night, the second uncle turned out all the fire cages in the house and prepared one for each elderly person in the family to keep warm. Ye Caiping is also treated very well because of her big belly, as for Chu Jiaqiang and others, if it is cold, they can only bring their own hot water bottles.

Tonight, no one dared to run to the beach to sing, the cold wind was howling, and even geese and swans were looking for a place with a lot of grass to hide. (To be continued.) )
