The expected light snow turned into light rain like last winter, and it had no effect on the crops in the field. Instead, the wasteland that was originally used for crop rotation was well moistened.

This rotation method was only slowly implemented by the villagers after one of Cao Wei's apprentices remembered to sue Wang Dahai this year.

The scientific explanation of crop rotation refers to the planting method of alternating different crops or multiple cropping combinations between seasons and years in the same plot. Crop rotation is a total biological measure after the combination of land use and land cultivation.

For example, a three-year rotation of corn this year, soybeans the next year, and wheat in the third year is a single crop rotation that takes place during the year.

Under the condition of more than one year, there is both annual crop rotation and annual crop change. For example, rice, rapeseed, rice, and wheat rotation are multiple cropping rotations.

In China, as early as the Western Han Dynasty, there were examples of leisure crop rotation. In the Northern Wei Dynasty, Qi Simiao's "Qi Min Yaoshu" has a record of "grain fields must be easy to age", "hemp wants to get good fields, no need to be empty", "where the grain field, mung beans, and small bean bottoms are the top, hemp and millet, so hemp is second, and coriander and soybean are the bottom", which pointed out the necessity of crop rotation and described the order of crop rotation at that time.

Proper crop rotation can yield high ecological and economic benefits.

For example, it can be used to rotate crops to prevent diseases, insects, and weeds. Many of the diseases of crops are infected by the soil, and if the parasitic crops infected with the virus and the non-host crops are rotated, the number of the pathogen in the soil can be eliminated or reduced, and the disease can be reduced.

Reasonable crop rotation is also an important way and effective means for comprehensive weed control. Because of the different measures used in the cultivation process of different crops, they have different inhibition and control effects on weeds in the field.

For example, water-to-drought rotation makes some xerophytic weeds lose their ability to germinate when flooded. Some associated or parasitic weeds, such as oat grass common in wheat fields and dodder vine common in soybean fields, can be eliminated or inhibited due to the loss of associated or parasitic crops after crop rotation.

Crop rotation also has the effect of balancing the use of soil nutrients and regulating soil fertility. However, because of the lack of suitable arable land and the large population in China. Crop rotation is not well practiced in rural areas.

Most farmers, because of their literacy or other reasons, only grow one crop for many years, and there is no concept of crop rotation.

But the mid-mountain village is different, scientific farming in the mid-mountain village is absolutely just talking about it from time to time. Thanks to the high price of the super vegetables that everyone grows, as long as the yield is even one percent, it can also be exchanged for high economic benefits.

Today's farmers know all kinds of media, and they also know all the dangers that growing a crop all year round and using chemical fertilizers can bring to the land, although they may not know everything, but they know a little bit about it.

It is like the soil is compacted, and the fertility is reduced. Pests and diseases are increasing, etc., but after they get used to planting a certain crop, they want to change the planting structure, if there is no higher economic benefit, it is tantamount to a dream.

This problem does not exist in the middle of the village, and now the super vegetables are sold so expensive, even if they plant one crop a year, it is enough for the family to live a well-off life.

So after listening to other experts talk about the benefits of crop rotation, there is no need to persuade much. Everyone consciously began to farm according to the rotation pattern described by experts in their own fields.

However, most of the lazy people are playing tricks, according to the practice of foreign farms according to the technicians, they directly divide their land into two parts, one part continues to grow vegetables, and the other part is wasted land.

Anyway, the family is not short of those few dollars. Let's listen to the experts, right? That's how people farm in foreign countries!

No one said anything about what these people did. Not to mention the children of the families who work in the village-run enterprises, even if they rely on the dividends of the village enterprises, they can live a much better life than the wealthy households in other villages.

The ground was not affected by anything. But the people in the village may have been really frightened by the sudden wind cooling, and the remaining families still replaced the simple greenhouses in their fields with formal steel-framed winter warming greenhouses.

It took another two days for all the families in the village to spend a lot of money on hiring people from five companies from the city that specialized in building greenhouses. With the overtime efforts, all the vegetable plots were covered by greenhouses.

That night, the snow on the road had not yet melted, and another light snow had fallen.

The arrival of this snow has caused great trouble for people's travel. Because the previous one had not completely melted, it was frozen because of the low temperature brought by this snow.

Needless to say, you know what the consequences will be if the road is icy. Suddenly, the originally bustling and flowing road suddenly became quiet.

The next day after the snow is the big market in the town, if it is usual, then early in the morning there will be groups of villagers or walking, cycling, or driving on the road, to the town to catch the big market.

But this morning, it was past eight o'clock and almost nine o'clock, and there were only a few lonely villagers on the road.

They carefully rode electric scooters or motorcycles, put their feet on the ground as much as possible, rubbed the ground, and walked slowly, for fear of slipping and falling.

The occasional tricycle, car or truck that passes by is even more cautious, and some can't even keep up with the good legs and feet of others!

But there is no way, this kind of weather is the most prone to accidents, and it is good to accidentally slip into the ditch, if you hit someone, it will be a big trouble! But it can't be helped, if it's okay, who will come out in this weather!

Yesterday, Wang Yong said that he was going to take Wenwen to the market, although it was snowing and the road was still slippery, but the little girl didn't care about this, she still ran to her godfather's house early and dragged the lazy godfather out of the warm bed.

After eating the "love" breakfast brought by his daughter, Wang Yong led Wenwen out of the gate and swept her mind, and her face showed a bitter color.

It's not a good road!

What if Wenwen was bumped on the road? A large group of people in the family still can't eat themselves?

But seeing that the girl was eager to try and couldn't wait, Wang Yong swallowed back the words that came to his mouth.

Grandma's, isn't it just that the road is a little icy? Can you still stump me? It's a big deal, Lao Tzu took a helicopter over!

It's just a matter of saying this in my heart, Wang Yong won't do such a high-profile thing. This person's head has been turning fast since he was a child, and he has a lot of ideas, no, he thought of a good idea when he thought about it.

A phone call went out, and not long after sitting in the sentry box at the entrance of the village, just comforted the girl who couldn't wait to be honest, a crawler bulldozer, a sweeper and a heavy truck appeared in the field of vision one after another.

But to Wang Yong's disappointment, the scene he expected did not appear. Because the snow on the roads has turned to ice, it is difficult for bulldozers to remove it.

Even after the bulldozer pushes it, the road surface will be even more slippery. Even the sweeper and heavy truck behind him ran cautiously, but just like that, it still slid sideways from time to time, which looked very thrilling.

"Wenwen, you see that this road is really not easy to walk, the godfather estimates that there must be no one on the big set, or we won't rush this set, and the godfather will take you there in the next big set, okay?"

As soon as Wang Yong's words fell, Wenwen's originally elated little face drooped, although she didn't say anything, and she didn't cry, but the loneliness on that face already made Wang Yong feel distressed and couldn't stand it.

Forget it, for the sake of my daughter, Lao Tzu is out of the way!

"Let's go, good baby, let's go with my godfather, let's fly to the market!"

After finishing speaking, he stood up, pulled Wenwen into a tracked personnel carrier that transported soldiers under the stunned eyes of the soldiers on duty, and went to the base with a bang.

If you want to say that this crawler vehicle is good, such a smooth road surface is stunned that there is no impact at all, not to mention the steady running, and the speed is not slow at all.

An electric version of the Black Hawk spun its rotors briskly, and soon rose from the tarmac, rising higher and higher, and after crossing a nearby hill, the nose was lowered and began to fly in the direction of the town.

Because the name of the flight was to investigate the impact of icy roads on the travel of the masses, the helicopter did not fly directly to the town, but kept circling along this section of the road.

After crossing the hill, the plane lowered some altitude, and through the glass windows, it was clear that the pedestrians were cautiously hurrying on the road.

Pedestrians who walk on two footboards are better, and people on electric cars, motorcycles, and even bicycles are the most careful.

The speed was set to the slowest level, with 120,000 points of caution, but even so, from time to time you could still see someone fall on the side of the road.

Fortunately, because everyone's speed is controlled, the speed is not fast, even if you fall, it is not a big deal. Get up, get on the bike, and then move forward more carefully.

The most dangerous thing is when two cars meet, or when they follow behind a car, then you need to be more careful. If you don't pay attention, on such a smooth road, there will be a traffic accident.

But no matter how careful you are, sometimes you can't avoid accidents.

Wang Yong saw two cars driving opposite each other on the road, because one car did not control the speed and direction, he stepped on the brake in a hurry, and as a result, he "kissed" a car coming from the opposite side.

The drivers of both cars got down to take a look at their cars, then talked a few words before returning to the car and closing the door. After a while, both cars lit up with double flashes representing an emergency.

Probably both cars are insured, and this is waiting for someone from the insurance company to come to the scene to investigate the claim! But this weather, when the insurance company comes over, I don't know what time it will be!

When the helicopter flew over the town, and saw that the market area that should normally be full of people and rubbing shoulders only saw a few vendors setting up stalls to sell goods, Wenwen was no longer in the mood to catch up with the big market, and shouted that she wanted to go home to make her godfather's newly learned oil and meat to eat.
