That day, Liu's father and the three of them were busy until the end of the evening before returning to the inn. Father Liu and Zhao Yi simply washed up and discussed today's affairs of the Fu Mansion outside.

Liu Su came back to the inner room, called for water, took a simple bath, went to look at the herbs placed on the windowsill, and sprayed some water on their leaves.

After finishing this, Liu Su also came to the outer room. "Father, tomorrow you will come to guide them. Garlic water is also mixed with clean water and sprayed on orchids as it is today. However, because the orchid insect infestation is more serious. There may be shoots that need to be soaked in garlic water and brushed off with a brush. In particular, the naan of aphids is very small because it has not yet been born. Garlic water alone can't kill.

Be sure to remove the naan as well. Otherwise, the adult worms will die, and when the naan will give birth to small aphids, the insecticidal plan we made will be in vain. They are very reproductive. In less than half a month, it will return to the status quo. ”

"Su'er, can all the bugs and garlic water kill them?" Liu's father asked.

"No, father. Garlic water is not a panacea, it can only work on microscopic insects such as aphids, nematodes, etc. But it can't kill red spiders, locusts, beetles and other large insects.

Flowers and trees will inevitably get sick throughout the year, but we can prevent them early. Like grass and wood gray water, garlic water can play a preventive role. For example, spring and summer are the most severe seasons for insect pests, so it is necessary to do a good job of prevention. ”

Father Liu was a little disappointed after hearing this. In the past, as long as the plant was seriously infested, we used fire to burn it. After this experience, I thought that I would not be afraid of insect pests in the future.

"It would be a great credit if we could solve the pest problem once and for all. The common people's crops can be harvested more, and those precious flowers and plants do not need to be burned. Father Liu said with emotion.

"Father, it's not that it can't be done. As long as you take precautions, pay attention to the ventilation of flowers and trees during the rainy season in spring. Spray more water in summer and autumn when it is hot and dry, so that the environment for flowers and trees to grow is moister. It can greatly reduce the occurrence of insect infestations. In addition, the spraying prevention of plant ash water and garlic water can eliminate insect pests to a certain extent. ”

"Senior sister, why is it dry in spring and wet in summer and early autumn? Isn't that a paradox? Zhao Yi listened to it for a long time, felt that he had questions, and immediately asked.

"Because pests need the ultimate environment for them to happen. The overall environment is very humid due to heavy rain in spring, and too hot and dry in summer and early autumn is an environment that can cause insect infestations. Of course, all the environment needs to be assisted by temperature, which is the extreme cold in winter. Causes of insect infestations that are less likely to occur. Liu Su explained.

"I see, then Su'er go and rest early, you are tired today. I have to get up early tomorrow to go to Fu's house. Father Liu suddenly received so much information and nodded again and again.

"Well, father, then I'll go and rest. You and your brother should also rest early. Liu Su got up and went to a few rooms and closed the door.

Outside, Father Liu was stunned for a while, looking at Zhao Yi and still thinking about something.

"Yi'er, you have to learn from Su'er in the future, she is smart and better than me. In the future, the master's family business will be handed over to her. But Su'er is a girl's family in the end, and there are still many things that need your help in the future. ”

"Master, don't worry, I will learn from my junior sister." Zhao Yi touched his head and said with a very honest look.

Inside, Liu Su listened to the conversation outside. Sitting at the head of the bed in a daze. This family is really nice, and maybe there are some things that should try to believe them.

Early in the morning of the second day, Liu's father and the three rushed to Fu's mansion. Liu Su took Liu's father and the two to the garden first to see the plants sprayed with plant ash yesterday. I opened the blade carefully and looked at it. There are not many live insects, and occasionally one or two hide at the interface between the leaf and the pole. After reading it, Liu Su said, "Father, look at this situation, this side of the garden can be sprayed with ash water again every two days." ”

"Well, yes, it does work well. Let's go and see what's going on on the orchid's side. Father Liu nodded with satisfaction.

In the remote courtyard, Liu's father and the others walked into the courtyard gate, and they saw a pear blossom wooden table under the eaves of the main hall, and there were three people sitting at the table. Behind him stood Steward Fu, two grandmothers in their 35s, four maids, and two maids.

Looking at the formation, Liu Su understood that today's insecticidal mode has become an ornamental mode. I'm afraid that the children of these rich and noble families won't be able to stand the smell of garlic.

Thinking about Liu Su, I was happy.

"Master Liu, this is the eldest young master of my family, the eldest lady, and the second miss, they are all here to kill insects today." Steward Fu came to Father Liu and said softly.

Father Liu and the three of them came to the bottom of the eaves stairs and bowed, "I've seen the eldest young master, the eldest lady, and the second young lady." Liu Su and Zhao Yi also saluted behind.

"Prepare to start, my two sisters can't wait to see it." The boy said.

"Yes, young master. But the smell may be a little big later, so the young master and the young ladies suggested covering their noses with handkerchiefs. I'll go and get ready first," Liu's father said.

"The brushes in Steward Fu's mansion may need to be used." Father Liu said to Steward Fu.

"Okay, I'll prepare this." Steward Fu said with a smile.

Liu's father walked to the big wooden barrel and opened the lid on the barrel. A garlic smell hits your face. Liu Su stirred the wooden barrel with a wooden stick to observe the color of the water. "Father, it's okay. Tell someone to mix it with water, and make it 1:10. ”

Liu Su whispered to Father Liu.

"Steward Fu, the soaked garlic water is already fine. Tell someone to fetch water, and mix it with 10 times the amount of water. After mixing with water, spray it on the orchid as it did yesterday. ”

"Okay, I'll arrange it." Steward Fu responded.

Liu Su took Zhao Yi to look at the orchids one by one. Pick out the serious ones that need to be brushed with a brush and set them aside.

When everything was ready, Liu Su took Zhao Yi to scrub those orchids with serious insect infestation.

And Liu's father took the people in the house to spray garlic water on those orchids.

For a time, the smell of garlic was everywhere in this remote courtyard. And it's so strong that it's uncomfortable to breathe. The first to be unbearable were the two young ladies in the house.

"Steward Fu's smell is too rushing, my sister and I went back first. Bijuan, you stay and help me watch. After the eldest lady finished explaining to Steward Fu, she covered her nose with a handkerchief and turned her head to say to a girl behind her.

"Yes, Miss." The girl named Bijuan bowed and replied.

"Cai Wei, you also stay and help me watch" The second lady also stood up, covering her nose with a handkerchief with a disgusted face, and said to a 10-year-old girl behind her.

"Let's go, sister, I'm almost ruined."

What happened here did not affect the work of Liu's father and the three.

The boy watched his two younger sisters leave. Stood up on his own. Covering his nose with a handkerchief, he walked behind Liu's father and watched. Behind him were two little maids, and behind the little maids were two maids, both of whom looked unbearable to the smell, and covered their noses with handkerchiefs.

"Ah, the eldest young master has fallen, and the worm has fallen. Like snow particles, it's too powerful. The little guy next to the boy who hadn't been here yesterday shouted.

"What are you shouting, Young Master Ben saw it yesterday, and he made a fuss." The boy said proudly.

The young man watched it and walked to Liu Su's side again. "Miss Liu Su, why do you want to use a brush to brush these?"

"Big young master, because these are more serious, the pests are piled up, and if you just spray them, you can only kill the insects on the surface. And I'll observe. There are also a lot of naan on these.

Naan can't be killed, you need to get them down artificially, otherwise they will regenerate new bugs after a few days. ”

"Miss Liu Su, what do you want Young Master Ben to promise you, you can say it and listen to it." Suddenly, the boy said.

"Young Master, I don't have any special requirements. I just want to transplant some flowers and trees that I like. Of course, I am on the premise of ensuring that the original flowers and trees in the house will not be harmed. ”

"Yes, only if you don't hurt the orchids and auspicious fruits of my father, as well as the peony flowers that my mother likes, you can do whatever you want."

"Then thank you, young master." Liu Su stood up and gave the boy a salute.
