In winter, the north wind is predominant, so the vegetable greenhouse is built with adobe on the east, west and north sides, and enclosed into a wall about two meters high. The south side is the place where the greenhouse transmits light, which in later generations was propped up with bamboo frames, covered with plastic film or covered with large pieces of glass.

In the northern part of the Ming Dynasty, there were few bamboos, so Zhou Zhi used wooden poles as support shelves. As for plastic film or glass, Zhou Zhi wanted to replace it with an airtight straw curtain.

It was only a small stretch of road from the barnyard in the north of the village to his own field, and Zhou Zhi first used a small cart to push all the adobe to the field. Then he compacted the place where the half acre of land was built and the wall was built, and he began to build it.

If it is a person, it is estimated that these tasks will take at least five days, but with the help of my sister Zhou Luyun, it is naturally much faster. It took more than three days to build up the entire wall.

Later, Zhou Zhi divided the half-acre field into three equal parts, and built a one-foot-square pipe with adobe around each piece, and the pipe was tightly pasted with mud to ensure that there was no air leakage. There are two exits to the pipeline, both outside the northern wall.

One outlet is built with a stove for heating, while the other is made in the shape of a chimney to extract the smoke. Such a structure was called "fire kang" in the north in later generations, and it is more clear that the pipes in the greenhouse are used for heating and heat dissipation to ensure the temperature in the shed.

In later generations, the technology of cultivating seedlings with fire kang was widely used in the seventies and eighties of the last century. Nowadays, however, it is extremely rare, after all, there are more advanced insulation and heating facilities.

Seeing that Zhou Zhi's things were strange, her sister Zhou Luyun really couldn't contain her curiosity, so she finally asked Zhou Zhi. Zhou Zhi no longer hid it, and truthfully told his sister that he wanted to grow vegetables.

Growing vegetables in the winter is something you can't even think of. As Zhou Zhi expected, Zhou Luyun was shocked when he heard it. But Zhou Luyun has already said that as long as it is done by her younger brother, it will not be wrong to think about it, and she will definitely support her younger brother. Although he was full of suspicion and thought that there was no possibility of success, he still worked tirelessly to help his younger brother work.

"I'll just say, there's a reason why Xiao Zhi left this half acre of land. My family is by no means a person who does not do his job properly and harms his family. Sister Zhou Luyun said with a slight smile.

When her mother-in-law Zhou He learned of Zhou Zhi's idea, she was also very surprised, and like her sister, she also thought that there was no possibility of success. But she is a very open-minded person, anyway, Zhou Zhi does not waste the family's money, the half acre of land is useless, Zhou Zhi can do whatever he wants, as long as he doesn't make trouble, the family is safe.

The wooden pole bracket used in the greenhouse is very easy to find, and there are a few at home, so if you don't have enough, go to the mass grave in the west of Baiyue Village. There are a lot of jujube trees there, and there are also quite a few elm trees.

It only took a day of work to erect the wooden frame.

Straw curtains need a lot, and it is very cold in winter, so the straw curtains must be airtight. The family planted a lot of rice this year, but most of the rice straw had to be left as feed for "Uncle Ma", and Zhou Zhi only used a small amount of his own home.

The rest is to go to Uncle Zhang's house to pick it up.

Uncle Zhang's family has a lot more fields than Zhou's, and naturally produces a lot of straw. In addition to using some for cooking on the fire, there is no need for ondol heating in winter. Zhang Hudan'er's younger brother Zhang Fu is eighteen years old and is a diligent person. I have already prepared a lot of dry firewood, ready to make a fire to warm the kang in winter.

With these rice straws from Uncle Zhang's family, all that Zhou Zhi needs to build a vegetable greenhouse is enough.

Make all the straw curtains in advance at home and store them temporarily. Now that the weather is still warm, even if you plant vegetable seeds, you don't have to use a straw curtain to avoid the cold.

On this day, Zhou Zhi got up early, read a few pages of the Analects, and then took out the wooden box given to him by Wang Ding, and took out the pen and ink. Spread the waste paper used by Wang Ding on the clay kang and write in a decent way.

Although the old master Wang Ding gave him a pen and paper, he has never used it these days. There are not many ink blocks, so you have to use them sparingly. Then there is the three-foot-high waste paper, although it looks like a lot, in fact, it can only be written on one side, and some of it has been put for a long time, the paper has long become black, as if it cannot be used, so these papers should also be used sparingly. After all, after using it, I don't know where to find it.

Do you expect your family to spend money on paper, pen and ink? Just kidding, as far as Zhou Zhi knows, the family can't even take out a few coins of silver. It is no wonder that the poor farmer has no source of money. I can only rely on selling eggs in exchange for some oil, salt and basic daily necessities.

This is the first time to pick up a brush after crossing the Ming Dynasty, and Zhou Zhi can't help but be excited. In later generations, he was an amateur calligraphy enthusiast and had a great affection for brushes.

In the past and present lives, I have the opportunity to hold a pen in my hand, which is also a great happiness.

He can write a clear and upright hand, full of muscles and strength. In later generations, Zhao Mengfu and Guan Sheng and his wife Xiaokai are very studied, although they have not seen their authentic works, but the later generations of fakes have seen a lot, and spent a long time copying.

He silently wrote one of the chapters of the Analects, put down the brush, held the paper in his hand, and sometimes nodded slightly, sometimes slowly shaking his head.

Well! There are still some places that are not grasped enough, but the pen power is there, but when the pen is put down, the pen is not good enough. You need to practice a good handwriting in order to make an initial good impression on the examiner.

This word must be practiced well.

Fortunately, there is still a lot of time, and there is no hurry.

Flip through the paper casually and look at the other side of Wang Ding's writing. Obviously, there are still many youths and shortcomings, which should have been written by Wang Ding earlier.

That day, he made a bet with Chen Wenju in Tiantou that Zhou Zhi had seen Wang Ding write. Wang Ding's handwriting is quite mellow and smooth, which is by no means something that can be practiced overnight.

Later generations of calligraphy teachers once said that words should be written life, and only by devoting oneself to them can the words be written to life. The so-called "words are like people" is this truth, sloppy and sloppy, can never sit down in a person can not write a good hand.

I only wrote one article today, and the vegetable greenhouse still needs a lot of firewood for heating in winter, so Zhou Zhi needs to prepare it quickly. Firewood can withstand burning and burn for a long time.

The poor people of Baiyue Village have to burn firewood for heating in the winter and burn clay kang at night. The firewood used for these is naturally the best firewood. In the southwest of Baiyue Village, there is a large mound on the road three miles away from the village, and the mound is overgrown with miscellaneous trees and jungles, from which the villagers cut firewood.

Zhou Zhi went out with an axe and went straight to the mound.

Because the weather is still warm, many households have not prepared firewood for winter. So firewood on the mound was everywhere. It was late autumn, and the leaves on the trees had not yet fallen. The chopped firewood is naturally wet.

I can't care so much, now I have to prepare the firewood, and when the greenhouse is planted with vegetables, there will be no time to chop firewood.

For several days, Zhou Zhi was busy chopping wood on the mound. These days, I thought that Chen Wenju would definitely take revenge, but I didn't expect that the Zhou family had been very safe for a while, and Zhou Zhi rarely even saw Chen Wenju's face.

Time flies quickly, in a flash, it is the beginning of October, Zhou Zhi prepared everything used in the vegetable greenhouse, standing in the field at this time, with an excited face, and suddenly remembered a sentence: dreams are to be had, what if one day it comes true?
