Spring-summer socializing.

Li Wu originally thought that there would be very few types of fruits sold in the Jinling market.

But when he arrived at the market, he was dumbfounded by the variety of fruit types in front of him.

And in the blink of an eye, thinking about it day and night, the girl Wang who was worried in her heart was now turned into a vegetable seller, sitting in a daze on the stall behind those hearty out-of-season fruits.

Li Wu quietly leaned over and asked in a low voice:

"What are you thinking?"

Miss Wang did not doubt him, and thought that it was her little sister who asked herself, so she sighed and replied:

"The Chincha Lady passed down the technique called the vegetable greenhouse, and in order to guide the construction and use of the method, he worked in the fields with the people in a friendly way."

"I heard the news and went to help, but I was sent to sell the first crops that were grown......

"Ah...... I'm so annoyed, I want to work with him by his side, and wipe his sweat, instead of being broken away and running to this market to sell some out-of-season fruits! ”

Li Wu said with a slight reprimand:

"As a daughter's family, she should learn piano, chess, calligraphy and painting, and read books and poems. How can you go to the fields to do all that kind of rough work, and then go to the market to sell your goods? ”

"You're still a girl who hasn't left the cabinet, so you're not afraid that you won't be able to find your in-laws' family in the future?"

Miss Wang heard that something was wrong, and turned her head to see that it was Li Wu.

"Ah, I said who it was, it turned out to be you."

"Then don't you study hard at home to gain fame, what are you doing in the vegetable market, don't you know that the gentleman is far away from cooking?"

When Li Wu heard this, he had to smile awkwardly.

Yes, not everyone has to live the right way, and not everyone can live the right way.

"I heard that the wife of Lord Qincha came from the capital to Jinling, and was his wife not there while she was working in the fields? If you have a lady here, even if you are not paid to sell fruits, you will not have the opportunity to wipe your sweat with water for Lord Chincha, right? So I don't think you need to be so depressed anymore. ”

Hearing this, Miss Wang was immediately unconvinced:

"Hmph, that kind of noble lady from the capital, how can she know how to take care of people, she will make trouble for Lord Qincha for a while, and I don't know how Lord Qincha likes such a girl."

Li Wu retorted in a low voice:

"Lord Qincha, who was born as a noble son, naturally likes the delicate lady of the capital, this is the truth of the world."

Miss Wang retorted excitedly:

"You don't understand at all, Lord Qincha is different, so he won't stick to these worldly views!"

"Don't look at Lord Qincha with vulgar eyes, he is not the same as those ordinary people at all!"

Li Wu wanted to refute, wanting to say that Lord Qincha may be different in being an official, but he is the clear stream of the world.

But when it comes to looking at women, they must still be the same as the world, they all like to be delicate and beautiful.

The rebuttal was stuck in his mouth again, and he couldn't say it for a long time, and finally he could only turn into a sigh.

He wanted to persuade Miss Wang to see the reality clearly, but why wasn't he the same as Miss Wang? They are all looking at people who can't ask for it, and they can't see the whole thing clearly.

"How do you sell fruit?"

So Li Wu changed the subject.

However, part of the reason is that he is actually quite interested in the out-of-season fruit that Lord-sama has made.

"Don't ask for money, give it away for free."

Miss Wang seems to be still angry with Lord Qincha, and wants to give the fruits he entrusted to sell to the citizens to eat.

"Huh."

Li Wu chuckled and shook his head.

"In that case, let's take advantage of Lord Qincha."

Then he took a watermelon the size of two apples from the stall and turned around and walked to the other vegetable vendors.

……

"Greetings from the Ministry of Industry."

"Today's letter is based on some thoughts on the cocoon, hoping to help the Ministry of Industry's agricultural tool reform."

The cocoon car is also called "cocoon plow" or simply "cocoon", the early cocoon car and cocoon plough have no clear definition, so the early cocoon is still called "cocoon plow" or simply "cocoon"

The earliest document that explicitly uses the word "cocoon" to refer to the special sowing farm tool "cocoon" may be the "Qi Min Yao Shu".

Cocoons have a long history and are widely used, and there have been records of cocoons in China as early as the Warring States Period, and in the Han Dynasty, there were already cocoons that began to take shape, and the original "cocoons" could only be sown at a time

A line, known as a cocoon.

After summarizing the experience of the predecessors and absorbing the advantages of the previous generation of seeders, I gradually had the idea of inventing the three-legged cocoon. Its use method is "three plows and a total of one ox, one person will be it, the next seed is cocoon, all take the preparation, and plant one hectare every day".

The three-legged cocoon can complete the ditching and sowing of the three ridges at the same time, which is suitable for the large-scale use of Pingchuan farmland.

In addition, the three-legged cocoon can also be adapted to wide row operations to sow corn, barley, wheat, soybeans, sorghum and other crops.

The main body of the car is made of hard wood, and the structure is formed in the traditional mortise and tenon structure.

The cocoon plough is made of iron and is molded by the traditional casting process.

In order to strengthen the firmness between different components, drill a small hole in the mortise and tenon joint, and then use bamboo tenon nails to pass through and play the role of rivets.

The legs and the part of the cocoon form a smooth downward arc, and the cocoon and the cocoon are chamfered everywhere, which visually forms a curved and straight contrast with other parts.

The cocoon foot is parallel to the cocoon car, and the main structure is at an angle of 80 degrees. The front end of the cocoon is widened to form a trapezoidal opening to facilitate the entrapment of livestock.

In addition, there are some two-legged materials that have been used in some areas of the folk industry to facilitate the reference of craftsmen in the design and manufacturing of the Ministry of Industry.

Its basic structure is shown as shown in the drawings attached to the letter, the total length of the cocoon is 200 centimeters, the height is 100 centimeters, and the main structure comprises six parts: the cocoon frame, the cocoon legs, the cocoon handle, the cocoon bucket, the cocoon ploughshare, and the cocoon wheel.

When sowing, pour the seeds into the cocoon and pull the cocoon with oxen. The sowing of the cocoon car pays attention to fast walking and shaking, slow walking and shaking, not walking and shaking, and it is necessary to straighten and shake evenly.

The cocoon leg and the cocoon frame are the supporting part of the whole tool, and the upper part of the cocoon frame structure is like an inverted "and" shape, and the main body bracket is the cocoon leg below, and its appearance is like a three-dimensional "π", and the cocoon frame structure adopts the mortise and tenon structure to be fixed as a whole.

The bucket and the two wheels are tightly fitted together, and there is room for a cow between the two wheels.

The handle is located at the top of the frame, which is the part of the car in direct contact with the operator in use, so the handle is a curved and rounded shape, which is conducive to the left and right hands to grasp, which is more in line with the habit of balanced operation.

The cocoon is divided into two parts: the front and the back. The front part is a container for storing grains, and the rear part is the part that communicates with the leaky seed tube.

Sowing needs to adjust the movable baffle of the cocoon according to the size of the seed type and the type of soil, so that the seeds flow out smoothly.

When the movable baffle slides up and down, the flow rate of the seeds also changes.
