North and South groceries

In addition to making soap every day, Luo Yong teaches Du Dalang how to paint.

To be honest, Luo Yong's own art level is not very good. Most of the only little foundation he has is hard-working for the pattern of the peony cushion in the past. It was no problem to teach his own disciples in the past. Now When you meet someone like Du Gou, you often feel stretched.

Fortunately, there are a few art textbooks in his space, and Luo Yong sneaked through them a few times when he was free, but he could barely handle them.

It's just that sometimes he is really annoyed by Du Gou's questions, so he can't wait to throw the books in the space to him. I won't serve you anymore, you can read the books by yourself.

Of course this is impossible.

Du Gou is also quite interesting, he is thirsty for learning and at the same time has a good grasp of the speed, he can always stop the car before Luo Sanlang blows his hair.

According to Du Gou's own wish, of course he hoped to be in front of Luo Sanlang all day long and let him teach him how to paint, but Luo Sanlang didn't seem to have much interest in painting, and would rather stay in the backyard of Luo's house making soap every day.

In the early morning of this day, Du Gou woke up early in the morning and suddenly thought of a question. After thinking about it, he couldn't figure out the answer, so he went to Luo Yong again.

Walking to the courtyard of Luo's house, Luo Siniang said that her elder brother had gone to the sheep shed, so Du Gou went there too.

Luo used this early morning to come to the sheep house to have a look at the growth of the alfalfa. Most of the seeds that had been sown earlier had already sprouted by this time, growing tender and thin grass leaves.

Luo Yong checked the soil moisture and found that it was okay, and there should be no need to water it for the time being. It would be even better if it rained again in the past two days.

On the wasteland not far from him, his disciples also got up to work at this time. They cut down the bushes growing on the wasteland and surrounded the alfalfa field as a fence to prevent the young shoots from being gnawed by goats. Food.

When Du Gou passed by, he saw Xu Dalang digging the roots of the tree with a hoe, so he went to him and said, "It's too laborious to dig like this, why don't you cut the bark?"

"Why cut the bark?" Xu Dalang raised his hand to wipe the hot sweat from his forehead, puzzled.

"You only need to cut twice around the trunk and peel off the bark in the middle. The tree will wither and lose its leaves in a short time. As long as there are no leaves to block the sun, it will not hinder the cultivation. After two or three years, the tree will be almost dead. It's time to rot, and then you can pull out the rotten wood." Du Gou explained to him.

Luo Yong happened to be walking this way at this time. Hearing this, he couldn't help but think of what he had learned in books before. Regarding the structure of the tree trunk, it is a tissue called phloem in the bark that is responsible for transporting nutrients.

Although this Dugou didn't know what phloem and xylem were, he knew that this method of girdling the bark could effectively make a tree wither and even die.

This is probably the wisdom of the ancients, because with such wisdom, human beings can develop their own civilization on this originally barren planet.

However, for those trees, this is simply a talisman. Humans don't even need to spend effort to cut down those thick trunks. They only need to gently peel off a circle of bark on each tree, and they can easily kill a whole tree. A piece of forest, so that the original forest land into arable land.

"Master?" Xu Dalang wasn't sure whether he should listen to Du Gou, seeing Luo Yong coming over at this time, he asked for his advice.

"Du Dalang is right." Luo Sanlang thought that eating meat is bloody and evil, and at the same time silently swallowed the piece of fat in his mouth. This is the land bestowed on him by the emperor. Use them for farming and breeding, where can we let miscellaneous trees grow.

Luo Yong, as a traverser who is already more aware of environmental protection, cannot give up his own interests for these trees, let alone other people at this time in the seventh century.

It is probably because of this that the lush plateau in front of me will eventually become the loess plateau of later generations.

Thousands of miles away, in the city of Chang'an.

Li Shimin was inspecting his royal manor at this time. Throughout the ages, the royal manor was mostly run by foreign relatives or other royal cronies, and they often did not pursue economic benefits.

It's just that the current emperor is really shrewd. Although he is not known for killing indiscriminately, he is also decisive. When working under such an emperor, everyone must work hard and not dare to act recklessly. The economic benefits of the Royal Manor turned out to be very good.

"...This piece of gourd grows well." The current saint praised all the way, and was very satisfied with what he saw today.

At this time, they were walking through a vegetable garden. There were various vegetables growing in the garden. A gourd was planted here, a loofah was next to it, a courgette was in front, and winter melon was in the back. The melons and vegetables at this time were That's about a few varieties.

The half-year grain of melons and vegetables mentioned by the ancients is basically these kinds of melons.The old pumpkin, which tastes sweet, soft and glutinous, is still growing on the American continent at this time, and it did not exist in the Tang Dynasty.

His Majesty the Emperor has never eaten old pumpkins, so he has no regrets in his heart at this moment. He is very happy to see that the growth of these farmers in his manor is obviously stronger than in previous years.

"The method of burning soil and dung is really easy to use." The official in charge of the management of this royal manor said: "Your Majesty also knows that the manure supply of this manor is rationed every year, and the same amount of manure is used. With the method of dung, the effect of fertilizing the land is obviously better than before."

"That's true." The saint also nodded.

The next day, the saint discussed state affairs with several ministers, and then talked about what he had seen and heard in the royal manor that day.

When the emperor treats his courtiers, he can't be serious and serious every time he meets with them, and occasionally he has to chat with them about family affairs and connect with them.

Basically, these ministers also have their own food towns and manors. When it comes to things in this manor, everyone has a common language.

It's not good if it's not lively, the emperor wants to chat with them about the family, how can they not give face?

"That Luo Sanlang is really a wonderful person, why don't I announce him to the middle of the capital and meet this person with all your lovers, what do you think?" the emperor said.

"Hahaha, the old minister also wants to meet Na Luo Sanlang, I heard that he is a handsome young man." Among the ministers, there must be some people cheering.

"I heard it's a coffin board." Another person joked.

"Whether it is a handsome young man or a coffin board, we will know after meeting him." The saint said with a smile.

After these people said a few words, Luo Yong was going to run thousands of miles to Chang'an City, but he didn't know it at this time.

At the beginning of spring, Luo Yong planted a few loofahs next to his pigsty, and the vines of the loofahs climbed and grew along his pigsty.

Early this morning, Luo Yong stood on the soil slope in front of his yard and saw two small loofahs growing on the grass shed on the top of the pigsty below. He hadn't eaten loofahs this year, so he couldn't help feeling a little greedy. , So I built a ladder to climb up, and picked off the two loofahs.

It just so happened that Goro was resting at home because of the school holiday. At noon, when Siniang was cooking, he helped Siniang, and the job of peeling the loofah fell into his hands.

In this era when there were no paring knives, peeling loofah skin with a kitchen knife or a small knife was a test of skill, and Goro's skill was not very good.

"How can you peel the skin so thick? You almost peeled off the two loofahs." Seeing the loofah he peeled, Si Niang couldn't help complaining. This was the first time their family ate loofah this year. These two, each of them couldn't eat a bite or two.

"..." Goro scratched his ears with a look of shame on his face.

"The rind of this loofah is really not easy to peel." Luo Yong was carrying a basket of soap out of the backyard at this time, and when he saw this, he spoke up to help Goro.

"Hmph, you know you're used to him." Si Niang snorted.In fact, these words were Erniang's catchphrase, every time Luo used to protect Siniang, she would repeat this sentence, but now it was used by Siniang.

"I'm not good at using a knife." Goro ran over to help Luo Yong carry the soap basket.

"It's nothing, it's just a loofah, I'll make you a planer in the future." Luo Yong said with a smile.

"Isn't that plane knife used for planing wood? Can it also plan loofahs?" Si Niang listened to it with disbelief on her face.

"Even planing knife?" Du Gou was planning to go to Xu's guest house to eat noodles with fried sauce. When he passed by Luo's yard, he heard what they were talking about about loofah planing knife. He was curious and turned around.

When Luo Yong told him his "idea" about the paring knife, Du Gou immediately became interested, and he stopped eating fried noodles, rode his horse, and headed for the city. I went, it is said that I am going to the iron sword shop to make blades.

"Brother, he's really gone!" Wulang ran out of the yard, stood on the small dirt hill next to his house, watched Du Dalang go away on his horse, and then returned gossiping with excitement. Go to the yard and report to Luo Yong.

"Just to peel a loofah?" Siniang said that those city people were too unreliable.

"What do you know?" Luo Yong laughed.

There is no way to compare Du Gou's vision and his two little kids' vision.

In the past few days, Na Du Gou also told Luo Yong what he had seen and heard in Laizhou. It turns out that in Laizhou, every spring is the season for aquila fish. This kind of fish is very fierce and cannot be caught with fishing nets. Fishing with a hook, they will spit out the hook again, which is quite troublesome.

Because it is difficult to catch and has a ferocious temperament, there are a lot of this kind of fish in Laizhou area. Especially in May and June every year, fishermen can neither catch needle beam fish nor other fish species. The flooding of one species will inevitably lead to invade the living space of other species.

In response to this situation, Du Gou came up with a method to catch the needle beam fish with a barbed hook.

They found a lot of dried gourds, baited the hooks, and tied them to the dried gourds. This string of gourds was scattered in the sea, and when they were brought back, they could catch many needle beam fish.

"This method is very good!" Luo Yong praised.Although I don't know whether the barbed fishhook was invented by Du Gou himself, but he promoted this method in the local area, anyway, it can be regarded as a benefit.

"Not necessarily." Du Gou shook his head and said, "The fish hook with barbs cannot spit it out after eating it. If the fisherman is not good at putting the hook into his hand, it is also difficult to take it out."

Luo Yong hardly dared to imagine the scene of the barbed fishhook piercing into the flesh.

During the work, there will inevitably be some bumps and bumps. Even farmers who are farming in the fields will occasionally be accidentally injured, let alone fishing on the sea.
