Although the flowers and plants in Princess Bao'an cannot be compared with thousands of hectares of crops, the area of ​​the greenhouse is so large and the flowers and plants are planted so densely. In this way, some of them must be abandoned, otherwise there will be no room for treatment for flowers and plants. Just looking at Princess Bao'an, these flowers and plants should be her treasures. I am afraid that giving up any of them will make her feel very distressed.

After hearing the treatment method introduced by Wu Chong, a look of distress flashed across her face. These flowers and plants were raised one by one by one. It is no exaggeration to say that in Princess Bao'an's heart, these flowers and plants are actually like her children, but now Wu Chong asked her to give up some of the flowers and plants, which was like cutting flesh in her heart.

In fact, Princess Bao'an's psychology is understandable. In later generations, many people did not get married and didn't want children, so they put their feelings on the pets they raised. For them, those pets are actually their children. Now Princess Bao'an has this kind of mentality, but she raises plants rather than animals, but no matter what it is, this kind of emotion is essentially the same.

"What should I do? It's too late to build another greenhouse now. You can't really move some of the flowers and plants outside to death." Princess Shoukang said with a headache at this time. She knew Princess Bao'an's love for flowers and plants more than anyone else, and she didn't want her sister to be sad because of these flowers and plants.

But at this moment, there was a sound of footsteps outside the greenhouse. Then Zhao Yan pulled Shu'er with one hand and pushed the door in with a small bucket in the other. When he saw that Princess Bao'an was also there, he immediately said happily: "Second sister, you are back. I happened to have prepared pesticides. Let's treat these flowers and plants together!"

"Treat the disease? Third brother, do you know how to cure these flowers and plants?" Princess Bao'an couldn't help but say in surprise when she heard Zhao Yan's words. Although she knew that Zhao Yan was knowledgeable and talented, she could not know everything, especially when it comes to raising flowers and plants, she never found that Zhao Yan had such interest, so after the flowers and plants got sick, she did not think of asking Zhao Yan for help.

"Hehe, second sister, you don't know. Although there are many types of flowers, plants, some aspects are actually common. For example, your flowers and plants will get downy mildew, and the crops in the fields will also get this disease. I happened to know some knowledge about the prevention and treatment of crop diseases. I happened to know the treatment of downy mildew, so I went to prepare some." Zhao Yan said at the end, proudly raised the small wooden barrel in his hand. He spent a lot of time to make this thing. So he came back so late.

"County... Prince, you... do you really know how to prevent and treat this verticillium Impotence?" At this time, Wu Chong next to him couldn't help but be excited when he heard Zhao Yan's words. Verticillium Impotence was just the name he gave to this plant disease himself, so although Zhao Yan said that this disease is downy mildew, it should refer to the same disease.

"Uh? Is this?" Zhao Yan was startled by Wu Chong. He was just concerned about talking to Princess Bao'an, and he didn't notice that there were still several men in the greenhouse. He didn't expect that one of them rushed over and talked to him with an excited look on his face.

"Hehe. This is Wu Juejian from the Sinong Temple. The second sister asked them to treat the flowers and plants. But they proposed an infeasible solution, but they didn't expect that you, third brother, have other solutions." Princess Shoukang suddenly smiled and said, and pointed out without mercy that Wu Chong and the other two had no good solutions for this disease.

Although Wu Chong felt a little embarrassed when he heard Princess Shoukang's words, he was eager to know whether Zhao Yan could really treat the disease of this crop, so he spoke again: "Wu Chong, the governor of Xiaguan Palace, was originally invited by the princess to treat flowers and plants. However, Xiaguan's talent was a little unfamiliar, and there was no good way for this verticillium, that is, the downy mildew disease mentioned by the prince. In addition, this disease is extremely harmful to crops. A verticillium outbreak two years ago caused thousands of hectares of land to be harvested and countless people were displaced. If the prince really knew how to prevent and treat this disease, it would be a blessing for the people of the world!"

"It turns out to be the judge Wu. Since you are interested in treating this kind of verticillin, let's help me start to take pesticides!" Zhao Yan had no idea of ​​keeping it secret. After all, he is not a farmer and does not need to rely on farming to support his family, so this pesticide for treating verticillin is of no use in his hands. It would be better to hand it over to a professional like Wu Chong to operate it. Maybe it can increase the income of the Song Dynasty's grain.

Wu Chong and the two garden craftsmen were overjoyed when they heard Zhao Yan's words. Verticillium ailment has always been a major problem in agriculture. Although they know some prevention and treatment methods, they can only operate on a small scale. Once the disease breaks out on a large scale, they will be powerless. However, although the pesticide mentioned by the Prince of Guangyang in front of them is unknown what the pesticide mentioned is, since it is a medicine, it should be used to treat sick crops. This is much better than their troublesome and cumbersome method.

After Zhao Yan finished speaking, he put down the small wooden barrel in his hand. At this time, Princess Bao'an and the others saw that there was a blue gem-like thing in the barrel, which looked very beautiful. Princess Bao'an and Princess Shoukang did not recognize this thing, but Wu Chong next to him recognized it at a glance. This blue gem-like thing should be alum, but this thing is generally used to dye cloth. Can it be used to treat crops?

Zhao Yan was not polite, so he directly ordered Wu Chong and two garden craftsmen to fetch water, and then divide the water into two parts, one of which dissolved the alum into it. When Princess Bao'an and Princess Shoukang saw that this gem-like thing actually melted into the water, they were all amazed.

Next, Zhao Yan took a pack of things from Shu'er, and after opening it, the smell was irritating. Now even Princess Bao'an recognized that these white stone-shaped things should be lime. Zhao Yan dissolved the lime into the other half of the water. Finally, she poured the solution of the gallbladder into the lime water and stirred it while pouring it. Finally, she got a blue oily liquid. It looked very beautiful, but the taste was not very good. It made Princess Bao'an and Princess Shoukang both frowned and took a few steps back, but Wu Chong and the two garden craftsmen looked as usual. After all, they usually need to take care of the garden, and sometimes the smell was even more irritating when fertilizing.

After Zhao Yan made the medicine liquid in a certain proportion, Shu'er took out a few bamboo water guns from behind like a magic trick. This thing was originally a water spray toy made by Zhao Yan for Shu'er and Siyue, and the principle was like a large bamboo needle. However, this time Zhao Yan made some changes to the water outlet, so that this bamboo water gun could spray out mist liquid and evenly spray the medicine liquid on the leaves of flowers and plants.

Zhao Yan distributed this special water gun to Wu Chong and two garden craftsmen. As for Princess Bao'an and Princess Shoukang, there was no. After all, this medicine liquid is actually poisonous, and it is best for women to not contact it. Besides, this greenhouse is not very big, so the four of them are enough. Shu'er originally wanted to snatch a water gun and play with it by herself, but Zhao Yan drove to Princess Bao'an.

Zhao Yan and Wu Chong started together, and soon sprayed the flowers and plants in the greenhouse with a water gun. However, at this time, there was an unpleasant smell in the greenhouse. Zhao Yan was worried about being poisoned, so she called everyone outside. It was not until then that Princess Bao'an had the opportunity to ask: "Third brother, do you have to spray this medicine every day? How many days will it take to cure the flowers and plants disease?"

Princess Bao'an obviously has no idea about pesticides. She even thought that she had to take medicine every day like a person who was sick, so she asked this question. However, Zhao Yan smiled and said, "My second sister doesn't know that plants are different from us. If you get this disease, you only need to spray it once. If you spray too much, you may be poisoned to death. After all, this medicine is poisonous and people must not drink it. If you accidentally eat it, you can drink a lot of cattle and goat milk or egg white to detoxify."

When Zhao Yan talked about it at the end, he specifically advised him on the detoxification method. The medicine he prepared was actually a commonly used fungicide in later generations, that is, Bordeaux liquid. This medicine liquid first appeared in the Bordeaux region of France, so it was named because of it. However, Zhao Yan did not intend to bring the name of this medicine liquid now, but he did not think of a suitable name for a while, so he did not introduce the name of this medicine liquid.

"It can cure crop diseases by spraying only once, which greatly saves time and reduces expenses. The prince's move is simply to benefit all the people of the world. In the future, when the people of the Song Dynasty mentioned the prince, they would definitely worship him and praise the prince's rebirth!" At this time, Wu Chong spoke excitedly again.

In fact, the reason why Wu Chong praised Zhao Yan so without any bottom line was that he hoped that Zhao Yan could hand over this medicine to himself, and then report it to the court after he did the experiment himself. Although the person who invented it was still Zhao Yan, he also had the merit of recommendation. Even with this merit, he could get rid of the crimes of that year and regain his lost future.

Zhao Yan is no longer the rookie who didn't know anything before. I immediately saw that the judge Wu praised him so much, but Zhao Yan didn't care much about this. Anyway, no matter who he gave this pesticide, he was the inventor of this pesticide, and no one dared to replace him. In addition, Wu Chong was able to work hard to treat flowers and plants for Princess Bao'an. Even if he didn't have any credit, he would have worked hard, so giving Bordeaux liquid to him was a reward for him. (To be continued...)
