Although the flowers and plants here 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, so you must give up some, otherwise there will be no place to treat the flowers and plants, just look at the appearance of Princess Bao'an, these flowers and plants should be her treasures, I am afraid that giving up any one of them will make her very distressed.

After listening to the treatment method introduced by Princess Bao'an, a distressed look did flash on her face, these flowers and plants were raised by her 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 flowers and plants, which is like cutting meat in her heart.

In fact, the psychology of Princess Bao'an can also be understood, in later generations, many people do not marry and do not want children, so they put their feelings on their pets, those pets for them, in fact, are their children, now Princess Bao'an is this kind of psychology, but she raises plants rather than animals, but no matter what it is, this feeling is essentially the same.

"What can I do, it's too late to build another greenhouse now, and I can't really move some of the flowers and plants outside to freeze to death." Princess Shoukang also had a headache at this time, she knew better than anyone else Princess Bao'an's love for flowers and plants, and she didn't want her sister to be sad because of these flowers and plants.

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

"Heal? Third brother, do you know how to cure the diseases of these flowers and plants? Princess Bao'an couldn't help but be extremely surprised when she heard Zhao Yan's words, although she knew that Zhao Yan was knowledgeable. But it is impossible to understand everything, especially the matter of raising flowers and plants, she has never found that Zhao Yan is interested in this, 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 and plants, in fact, some aspects are common, such as your flowers and plants will get this downy mildew, and the crops in the field will also get this disease. When Zhao Yan said at the end, he proudly raised the small wooden bucket in his hand, in order to make this thing, he spent a lot of time. That's why I came back so late.

"County ...... You, the king of the county, ...... Do you really know how to prevent this Verticillium? At this time, Wu Chong, who was next to him, heard Zhao Yan's words, but he couldn't help but be excited. Verticillium wilt is just the name he gave to this plant disease, so although Zhao Yan said that this disease is downy mildew, it should refer to the same disease.

"Huh? Who is this? Zhao Yan was taken aback by Wu Chong, just now he was only talking to Princess Bao'an, and he didn't notice that there were still a few men in the greenhouse, and he didn't expect one of them to rush over and talk to him excitedly.

"Giggles. This is the Wu Judge of Sinong Temple, and the second sister invited them to treat the flowers and plants. But they came up with a not very feasible solution, but they didn't expect that you would have other methods, third brother. Princess Shoukang suddenly smiled at this time, and mercilessly pointed out that Wu Chong and the three of them had no good way to deal with this disease.

Although Wu Chong felt a little embarrassed when he heard Princess Shoukang's words, he was eager to know if Zhao Yan could really cure the disease of this crop, so he spoke again: "Wu Chong, the supervisor of Xiaguan Palace, was originally invited by the princess to treat flowers and plants. But the lower officials are not knowledgeable, and there is no good way to do this Verticillium wilt, that is, downy mildew in the mouth of the king, and this disease is extremely dangerous for crops, and a Verticillium wilt outbreak occurred two years ago. Thousands of hectares of fields have been harvested and hundreds of people have been displaced, if the king of the county really knows how to prevent and treat this disease, it is really a blessing for the people of the world! ”

"It turned out to be Judge Wu, since you are interested in treating this Verticillium wilt, then help me start spraying pesticides together!" Zhao Yan didn't have any thoughts of keeping it secret, after all, he was not a farmer, and he didn't need to rely on farming to support his family, so this kind of pesticide for the treatment of Verticillium wilt was useless in his hands, so it was better to leave it to a professional like Wu Chong to operate, maybe it could increase the grain income of the Great Song Dynasty a lot.

Wu Chong and the two gardeners were also overjoyed when they heard Zhao Yan's words, Verticillium wilt has always been a big problem in agriculture, although they know some prevention and control methods, but they can only operate on a small scale, once the disease breaks out on a large scale, then they can't do anything, but although the pesticide in the mouth of His Royal Highness the King of Guangyang County in front of him doesn't know what it is, but since it is a medicine, it should be used to treat sick crops, which is much stronger than their troublesome and cumbersome methods.

After Zhao Yan finished speaking, he put down the small wooden barrel in his hand, and then Princess Bao'an and they saw that there was a blue gem-like thing in the bucket, which looked very beautiful, among which 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 bile alum, but this thing is generally used to dye cloth, can it also be used to treat crops?

Zhao Yan was not polite, and directly ordered Wu Chong and the two gardeners to fetch water, and then divide the water into two parts, one of which dissolved the gallium into it, and when Princess Bao'an and Princess Shoukang saw that this gem-like thing actually dissolved into the water, they were also amazed.

Next, Zhao Yan took a bag of things from Shu'er's hand, and after opening it, the smell flushed his nose, and even Princess Bao'an recognized it, these white stone-like things should be lime, I saw Zhao Yan dissolve the lime into the other half of the water, and finally poured the bile alum solution into the lime water just now, and stirred while pouring, and finally got a blue oily liquid, which looked very beautiful, but the taste was not very good. Princess Bao'an and Princess Shoukang both frowned and took a few steps back, but Wu Chong and the two gardeners looked as usual, after all, they usually needed to take care of the garden, and sometimes the smell was even more rushing when fertilizing.

After Zhao Yan made the liquid medicine according to a certain proportion, Shu'er took out a few water guns made of bamboo from behind as if playing a trick, this thing was originally a water spray toy made by Zhao Yan for Shu'er and Siyue, the principle is like a large bamboo needle, but this time Zhao Yan made some changes to the water outlet, so that this bamboo water gun can spray a mist liquid, and the liquid medicine can be evenly sprayed on the leaves of flowers and plants.

Zhao Yan gave this special water gun to Wu Chong and the two gardeners, as for Princess Bao'an and Princess Shoukang, they didn't, after all, this liquid is actually poisonous, and it is best for women not to touch it, and this greenhouse is not very big, the four of them are enough, Shu'er originally wanted to grab a water gun to play by herself, but was driven to Princess Bao'an by Zhao Yan.

Zhao Yan and Wu Chong worked together, and soon sprayed the flowers and plants in the greenhouse with a water gun, but at this time the greenhouse was filled with a bad smell, Zhao Yan was worried about poisoning, so he called everyone outside, and it was only then that Princess Bao'an had the opportunity to ask: "Third brother, do you have to spray this medicine every day, and how many days will it take to spray it to cure the disease of flowers and plants?" ”

Princess Bao'an obviously has no concept of pesticides, and even she thinks that she has to take medicine every day like a person is sick, so she asks so, but Zhao Yan smiled at this: "Second sister doesn't know, plants are different from us, and you only need to spray once if you have this disease, if you spray too much, maybe you will be poisoned, after all, this medicine is poisonous, people can never drink it, if you eat it by mistake, you can drink a lot of cow and goat milk, or drink egg white to detoxify." ”

When Zhao Yan said the end, he also specially advised the method of detoxification, the liquid he prepared was actually a fungicide commonly used in later generations, that is, Bordeaux liquid, this liquid first appeared in the Bordeaux region of France, so it was named because of this, but Zhao Yan did not plan to move the name of this later generation now, but he didn't think of a suitable name for a while, so he never introduced the name of this liquid.

"Only once spray can cure the disease of crops, which can greatly save time and reduce expenses, the county king's move is simply for the benefit of all the people in the world, in the future, when the people of the Song Dynasty mention the county king, they must also bow and worship, praise the regeneration grace of the county king!" At this time, Wu Chong said excitedly again.

In fact, the reason why Wu Chong praised Zhao Yan so bottomlessly also had his own plans, that is, he hoped that Zhao Yan could hand over this medicinal liquid to himself, and then report it to the imperial court after he personally did it.

Zhao Yan is no longer the kind of rookie who doesn't know anything before, and he immediately saw that this Judge Wu should have some selfish intentions in praising himself so much, but Zhao Yan didn't care much about this, anyway, no matter who this pesticide was handed over, he was the inventor of this pesticide, and absolutely no one dared to take his credit. In addition, this Wu Chong can work hard to treat flowers and plants for Princess Bao'an, even if there is no merit, there is hard work, so giving him Bordeaux liquid can be regarded as a reward for him.
