So Li De's approach is still to cultivate it in a unified manner, and he handed over some of the potatoes to the merchants who contracted the fields for planting.

After they have achieved results, the city guards will pay for the acquisition. There is no limit on how many things the merchants will leave behind.

Today, there are more types of vegetables. Cabbage, carrots, cucumbers, onions and tomatoes brought back from Europe can be seen in the vegetable market in Youzhou.

The price of new vegetables is very expensive to sell and is related to the quantity of supplies. After all, most of them still need to be cultivated. The part that can be put on the market is taken out by merchants and people who try it out.

The head of the agricultural affairs department of the Chengshoufu has begun to test the greenhouse planting as required by Li De.

The main thing they use is gauze, which has strict requirements for temperature control. People who know greenhouse planting are not just Li De, but they really know when recruiting talents in this area.

In fact, the principle of greenhouses is not a product of modern people. It has taken shape more than two thousand years ago.

According to the biography of Xunye of the Book of Han, "Taiguan Garden grows onions, leeks and mushrooms in winter, covers them with veranda, and burns fire day and night, and waits for the warm air to grow. The trusted officials think that these are all things that are out of time."

Although gauze is not as transparent as plastic cloth, it can still grow winter vegetables.

Li De thought of many ways to transform the greenhouse and the effect was not obvious, so he put his ideas on the glass greenhouse.

Even if the investment and construction of such glass greenhouses is much higher in modern times, it has many advantages, which are very transparent and safe and have a long durability.

For the ancient development level, glass plates cannot be manufactured now, so the technical difficulty is not very large.

Even if Li De tried his best to start with making glass plates, the theoretical possibility of engineering automation firing is not high, but it can still be achieved by using some manual and clumsy methods.

What Li De thought of was to use plastic models to use suppression.

The investment is very large and time-consuming, but greenhouses do not necessarily require all the materials to be made of glass plates.

In fact, try to make the light transparent in the house and install more windows.

Anyway, it was all experimental attitude and wasted some money. It was understandable that the Chengshoufu was very optimistic about this project. It was really costly and I was afraid that the cost would not be recovered in a few years.

But who made Li De persist?

Li De's approach is not blindly trying to waste money, just like investing in casino projects. Now that there is demand, the blacksmith workshop will improve technology according to the needs to achieve the goal.

Only after giving the goal can the craftsmen strive for it. The technology of firing glass is already very mature, and transparent glass products can be burned.

Now it is nothing more than asking them to change the finished product of burned glass. What the requirements for craftsmen are to innovate.

First, you can make a glass plate by yourself and then make more glass plates, and learn from it to improve processing technology to make production easier and increase output.

There is nothing that costs money to conduct scientific experiments.

In a few years, Li De was very concerned about the technological development of Youzhou, especially the technological development of the Blacksmith Workshop was the fastest.

Especially after the application of steam engines, after several years of technical reserve, steam power has now become a new power mode.

Various steam equipment is emerging one after another, including water pumps, well drillers, cranes, tunnel tracks, etc.

At present, only the production of glass is the most outstanding. Who started with glass when Youzhou was out of money before?

Nowadays, glass products are still made by themselves, and sales are shipped little by little through merchant channels. The finished products are far more fired than the products shipped.

The value of glass is more expensive than gold. If there are too many, it will depreciate. Just like many businessmen who are engaged in kiln burning sometimes find some irregular glass occasionally.

It wasn't that important that these glasses could be used for money, but there were too many kiln workshops in Youzhou. Over time, the firing of glass began to appear. In the end, some merchants began to ask people to experiment with burning glasses.

After all, it is worth burning several furnaces of bricks and stones on a piece of glass.

The merchants are very brave, and after success, they will get more, but the result is that they really burn glass.

There is a success of a family and countless people think about it, so they ask for cooperation and those who buy technology only pay for money. How can people not be moved?

Smart businessmen naturally took advantage of the recipe and handed over the recipe. They are not stupid and good things are too easy to attract people to covet them. In Youzhou businessmen are protected, but who knows if anyone will have evil intentions.

The city guards would not interfere with the affairs between merchants, but the price of glass products dropped significantly after that.

For this reason, the glass workshop under the name of the city guardian mansion suffered some losses, but compared with the glass products made by merchants who have just started, it is still competitive.

The development of the Liuli Workshop is not smooth, but it really makes a lot of money. Li De is very frivolous about Liuli products, mainly asking them to process some practical things such as cups, bowls and chopsticks.

During festivals, these products are used as gifts to distribute them to everyone. Over time, the requirements for the workshop are not very high.

Now we need to let craftsmen overcome the production technology of glass plates to be completed.

Li De found that although Youzhou's business development was very rapid, the technology development was still a bit slow. In this regard, he decided to add study subjects to the school so that more people could explore new knowledge.

Especially, theory and practice should be well combined. People who have learned will have a good foundation in their work, and talents are needed in chemistry and industry.

He really can't help much with advanced academic knowledge, but he can use a way to promote some good things.

For example, he thought of putting the excellent students in the school together to invent and create after graduation.

The initial work is to allow them to improve their existing production tools and production equipment, and they can get rewards as long as they are practical.

Use money to drive these people’s innovation motivation, the more money they get, the more money they get, there is no limit on their research field.

Not only those with academic foundation can join in inventions, but even workers can join in the premise that they have made innovations in the tools and equipment they have mastered.

Li De's method was naturally to publish in newspapers and Youzhou encourages inventions and creations to receive generous rewards after passing the review.

The first person to submit the invention is not someone else, it is Li Jing. He was the first to buy bicycles before, and he received rewards for participating in the competition.

His invention is actually very simple, installing a bicycle with a hook, which can accommodate a lot of things.
