The vegetable greenhouse, in fact, is a greenhouse, which can transmit light, keep warm (or heat), and make people eat out-of-season vegetables in the season that is not suitable for plant growth. Pen & Fun & Pavilion www.biquge.info

Generally, vegetable greenhouses use bamboo structure or steel structure skeleton, which is covered with one or more layers of thermal insulation plastic film, so as to form a greenhouse space. The outer membrane does a good job of preventing the loss of carbon dioxide generated by the growth of vegetables inside, so that the shed has a good thermal insulation effect.

In the Great Song Dynasty, of course, there was no such thing as a steel structure, and Wuhan University could only use bamboo poles and wood as arch materials to build the most basic support.

The advantages of this are that it is easy to obtain materials, easy to build, and low cost; But the shortcomings are also obvious, the arch has low strength, poor wind and snow resistance, easy to decay, needs to be repaired and replaced every year, and the operation and management are not very convenient.

And even so, in order to build a success, it also made Wuda tired.

The fields in ancient times were not as neat as those in later generations, and to build greenhouses, it was necessary to avoid building sheds obliquely, which made Wuda suffer.

Can only build, while trimming the land, in this cold weather that has entered the winter, the cold wind is biting, that sour, tsk, sad to death.

Fortunately, there are many people in Wufu, and Wuda still has the power of life and death of 500 households under the name of Wuda, and under the absolute high-pressure policy, the construction is quite smooth.

However, in this way, Chen Liu's people's evaluation of Wuda became worse and worse, and they all said that Wuda was an arrogant and unreasonable guy who ate people and did not spit out bones, in the words of later generations, it was Zhou Papi.

However, after the completion of the project, the Wufu paid the people an absolutely generous salary, which calmed down some of the people's hearts slightly.

But the people who got paid still didn't have a good opinion of Wuda, and they all said that he was a stunned young man who didn't understand the land, and he messed around and tossed around in the cold.

Nalan Lengfeng has not come to bother Wuda recently, of course, this does not mean that he is optimistic about Wuda's so-called planting of green vegetables in winter, he just received the first payment from Wuda, and is busy buying winter grain for the people of Chenliu.

But in any case, Wuda's ears were finally a little quieter.

The vegetable greenhouse has been built, the most critical problem is coming, there is no plastic film in this year, and there is no tempered glass.

Wuda pondered for a long time, and finally decided to go to Beijing in person and ask for help from Tongfu.

As for Song Huizong, he once said that he Wu Zhi was not allowed to enter Beijing without a will, just treat it as a fart, as long as Lao Tzu does not enter the palace, can you still know whether Lao Tzu can enter the capital or not?

Sang well in "Song of a Good Man",

"Let's go, you have me, you have everything! Hey, hey, it's all there! ”

"When the road is uneven, I roared, I shot when I should shoot, and I broke into Kyushu in a hurry!"

Wuda hummed a song and sang a song, traveled lightly, and went straight to Bianjing.

Maybe it's because of the cold wind, maybe it's because he sings out of tune, in short, it's a good song, and he sang it as a ghost crying wolf, judging from the twitching of the corners of Zhang Liang and Wu Gang's mouths next to him, it is enough to show that he has run directly to his grandmother's house.

When Wuda was in Yanggu, he didn't like to lead a large team of people to swagger through the city, and when he came to Bianjing, he still didn't like to be high-profile, but in order to prevent Sikong Shangfeng, who had been hiding in the shadows and waiting for an opportunity, from having bad intentions, Wuda brought Zhang Liang and Wu Gang, two confidants of Wufu.

In fact, Wuda originally wanted to take Wu Song with him, but there was no way, with Zhou Tong coming to Chenliu, a group of people from Wufu came one after another, including Hu Sanniang, who was fighting with Wu Song, and Fang Jinzhi, who had an unclear relationship with Zhang Liang.

Although Fang Jinzhi is Fang La's niece, she has a shy personality and is embarrassed to pester Zhang Liang, while Hu Sanniang, who has a bold and uninhibited personality, is open-minded in the name of asking for martial arts, pulling Wu Song all day long, which makes Wu Da happy but a little worried.

Gentle Township has always been a hero's mound, and I hope that Wu Song, a hero who fights tigers, will not change much.

All the way, the wind was light, entered Bianjing, and went straight to Tongfu.

Thanks to Wuda, almost everyone in Tong Mansion knows that he has a close relationship with Tong Guan, and if it is someone else, he will definitely be turned away.

The reason is very simple, General Tong has recently been recuperating in the closed house.

When Wu Da heard the news from the housekeeper's mouth, he was shocked.

Although Tong Guan has experienced a hundred battles, he is already a 60-year-old old man after all, and at this age, it is indeed easy to get sick in the cold weather of autumn and winter.

However, when Wuda walked into Tong Guan's room, he suddenly felt a row of crows screaming and flying over his head, full of black lines.

I saw General Tong, who was "recuperating from the house", in this cold day, rolling up his sleeves, roasting the fire, stewing hot bones, drinking wine in a big bowl, and eating meat in large pieces.

Dog, day, look at this virtue, fart closed house to recuperate, obviously it is cold, too lazy to go to court, simply make the most unreliable excuse, stuffy at home to enjoy happiness.

Wu Da sat next to Tong Guan, reached out and took out a pair of long bamboo chopsticks, scooped up a few big bones, gnawed his mouth full of oil, and beckoned Zhang Liang and Wu Gang to eat together, muttering: "Uncle Tong is sick, things that are too greasy are not good for his old man's body, don't be polite, let's help Uncle Tong destroy the enemy together!" ”

Tong Guan grinned, not annoyed.

But after all, he is a general with a heavy army, and his power is monstrous, of course Zhang Liang and Wu Gang can't really sit down, just stand on the sidelines, watching Tong Guan and Wu Da, one old and one young grab meat to eat.

After eating and drinking, Wu Dazhu hummed, Tong Guan lifted the wine jar and drank a few sips of wine, and asked: "Boy, you have been holding the name of the old man recently, and the tossing movement is really not small, do you think the old man is willing to stay in the house to recuperate?" Idle! It's almost a bird! It's not all because you have made a money village out of the crowd, the group of bastards in the Cai Mansion of the household department always questioned the old man in the court what he wanted, not to mention that the old man didn't know what you were going to do, even if the old man knew, he didn't want to deal with them, so he made an excuse to close the house to recuperate, and simply didn't go to court, out of sight. What is the so-called matter when you come to the house now? But something went wrong with the bank? ”

Wu Da's heart warmed.

In fact, Wu Da just sent someone to tell Tong Guan about Qian Zhuang and wanted to use his reputation as a backer, and did not explain the reason in detail, but Tong Guan still didn't ask more, but silently resisted for him.

Wu Da's eyes were slightly red, this was the first time he felt unconditional trust and support from Tong Guan, even if it was mixed with a little selfishness, but so what?

didn't get up, and saluted respectfully, "How can Wu Zhi be so virtuous, can Uncle Tong take care of ...... like this"

Tong Guan pursed his lips, "Don't talk nonsense, hurry up and talk about it, what's going on in Qianzhuang?" The household department is going to be turned upside down! ”
