The afternoon sun shines in the glass room, wrapping the flowers and plants in the room with a bright and dazzling halo. On the neat soil rows on the ground, seedlings bathe in the sun, and are transparent all over.

Yuwen Wen looked at these budding pepper seedlings and then at the vitality of the glass house, very satisfied.

The fleet brought back many peppers (fruits) from the Americas, and each pepper has many seeds, so shortly after the peppers "reached the shore", their cultivation work began in various parts of the south.

Chili peppers were also started to be planted in the Chang'an Palace. The seeds planted in the flower pots sprouted smoothly, and the seedlings were lush and green. In Yuwen's opinion, they were really pleasing to the eye.

Of course he didn't know how to grow chili peppers, but he felt that since the origin of chili peppers is hot, he thought that this crop might not be able to survive in winter, so he simply planted the chili peppers in a glass greenhouse to ensure that every seedling can survive the winter safely, live for a few more years, and bear more fruits after each seedling grows.

It is midsummer now and the weather is hot, so the doors and windows of the glass house as a greenhouse have been opened. In winter, the doors and windows are closed and the effect of the greenhouse can be realized, so that the peppers can grow in a higher temperature environment.

This is greenhouse cultivation technology, which can increase the yield of many crops, especially some crops that cannot survive the winter in cold areas. This cultivation technology can effectively "prolong life" and is now just for use on peppers.

In this way, when the Hebei region, which will snow heavily in winter, starts to grow peppers on a large scale, in winter, farms with strong financial resources can still harvest peppers and sell them with greenhouse cultivation techniques.

Although peppers are new to the Central Plains of this era, Yuwen Wen has absolute confidence that peppers are popular all over the world, because the name of "the empire of big foodies" is not false, and people's demand for peppers must be a bottomless pit.

Therefore, it is Yuwen Wen’s decision to popularize peppers as soon as possible instead of making them a luxury that rich people can enjoy. The most effective way is to plant them on a large scale all over the country.

When there is a huge demand for chili peppers everywhere, more and more farmers will naturally grow chili peppers.

This is a small goal. When Yuwen Wen wants to strengthen foreign exchanges, he must bring tangible benefits to the domestic people. Chili, an indispensable economic crop in future generations, must be promoted quickly.

Maybe in a few years, the production of chili peppers in various places will increase, and various "spicy dishes" will appear.

For example, "Sichuan cuisine".

When Yuwen Wen thought of the "Sichuan Hot Pot" known for its hemp, spicy, fresh and fragrant, he instantly felt that his life path became much brighter.

Why do Sichuan people like to eat spicy food?

There is a saying that Sichuan has a lot of rain, and it is cloudy and cold when it rains, and the air is humid. People eat chili peppers to drive away the cold and remove dampness, and use chili peppers as seasonings.

Is this true? Yuwen Wen doesn't know, but he is famous for knowing that Yun, Gui, Sichuan and Hunan can eat spicy food.

So he felt that popularizing chili in these places and turning it into a place of production of chili peppers can not only meet dietary needs but also serve as a cash crop, which is also a great thing for the people.

Yuwen Wen was happy when he looked at the pepper seedlings on the ground, and Chen Wu, who was accompanying him in the glass room, looked around with fun.

Even in the twelfth month of winter, she could still eat some fresh fruits and melons in the palace. At first, she was not sure about the specific reason, but now she realized that it was due to this glass house.

Of course she didn't understand the specific principles, so Yuwen Wen gave a live explanation.

With glass, a heat-insulating "greenhouse" can be built. The sunlight enters the room through the glass windows, leaving heat, so the indoor temperature is higher than that outside, which is particularly outstanding in winter.

Some plants that only blossom and bear fruit in summer and autumn can "grow off-season" in a warm greenhouse. Therefore, greenhouse cultivation technology can allow wealthy families to enjoy fresh fruits, vegetables, and even flowers in the cold winter.

However, the thermal insulation effect of glass is poor. If the planted crops require a high ambient temperature, it is best to use double-glazed windows in the greenhouse. However, even so, a large-area greenhouse with glass windows will still have poor insulation effect in the cold winter.

Therefore, other heat sources, such as hot spring water, should be introduced into the greenhouse.

However, hot spring water is mostly in the mountains, so if the greenhouse needs to ensure a higher indoor temperature, boiler water or "heating" circulating hot water can be used to heat the greenhouse with a larger area.

With the popularity of "heating", it is no longer an extreme luxury to supply hot water to greenhouses in winter, so greenhouse cultivation technology has now become popular, and it is no longer difficult for wealthy families to eat some of their own "off-season vegetables" grown in winter.

Of course, because Yuwen Wen is the emperor, according to the rules, subjects should avoid the word "Wen" and cannot be called "greenhouse", but should be renamed "warm room" or "warm room".

As for "technical terms" such as temperature and water temperature, there is no way to avoid it, so I can only give up. Of course, Yuwen Wen himself doesn't care about this: as long as it is beneficial to the national economy and people's livelihood, what's the harm in the word "warm" is being talked about by the people of the world all day long?

The popularization of warm room (greenhouse) cultivation technology has led to profitable "warm rooms" in major cities. For example, in or near Chang'an City, there are many "warm rooms" that specialize in planting off-season vegetables, providing rich families with various "off-season" vegetables and fruits.

There are flowers and even lychees.

Hearing this, Chen Wu was very surprised: "There are lychees too? Could it be that they are planting lychees trees in the warm room?"

"Yes, growing lychees in a warm room is not cheap, but rich people don't care about money if they want to show off their wealth."

Yuwen Wen smiled and shook his head, and said, "Although canned sugar water lychees are worthy, they are not as powerful as picking and eating fresh lychees."

He took Chen Hua out of the glass room and came to the imperial garden outside. On the grass bathed in the sun, several large chickens were taking a leisurely walk.

The size of this chicken is obviously larger than that of ordinary domestic chickens, and its appearance is also different from that of common domestic chickens: wide breasts, long mouths, no feathers on the head and neck (upper part), but has coral-like red dermatoma.

There is a red sarcoma on the upper part of the chicken's mouth, with a strange sound, and a bunch of beards on the chest, like a pig's bristle. The feathers on the body are black, and the tail feathers can be separated and spread into a folding fan shape.

Chen Wu looked at these "strange chickens" curiously and asked interestingly: "Erlang, in that America, is the local poultry, this kind of strange chicken?"

"Yes, this is the local poultry. The fleet brought some back. It was called chickens, but it was indeed like chickens in the Central Plains, but it was obviously different. Its body was black and red, and its head seemed to be on fire, so it was named Turkey."

Yuwen Wen pointed to these American turkeys that flew across the sea to the Central Plains and smiled: "This turkey is much larger than the chickens in the Central Plains, with more meat, but it is a bit rougher. It is said to be not delicious, but even so, it would be good if you can figure out a suitable cooking method or even use it to make meat floss."

"Didn't you say it for your husband? The world is so big. In those places we haven't discovered before, there will definitely be strange flowers and plants, rare birds and beasts, and there will definitely be good things."
