Lu Caiqing and Song Ziyu were very happy, watching the old man find the joy of his lost things and returning them to their original owners, and they were also happy.

"The little things that are done with your hands, the old man doesn't have to care too much." Song Ziyu looked at the old man's happy face and said.

Lu Caiqing and Song Ziyu went back to the room after a few polite words with the old man, and when it was time for dinner, it was still Xinlan who came to call them, although they couldn't get used to her, after all, they lived in someone's house, and after dinner, Song Ziyu took Lu Caiqing out again.

Because Lu Caiqing really likes the fresh vegetables here, so he and Song Ziyu slipped into the vegetable garden again, this time it is different, many people in the field are watering and hoeing, although some melons and fruits have borne fruit, but the planting period is different, and the flowering and fruiting time is also different.

Lu Caiqing inadvertently saw the old man in the day again, he and He Bo were planting sticks for the beans that grew vines, Lu Caiqing saw them and thought that they should not be popular here to use thin bamboo poles as support, so many beans have to insert a thin wooden stick under the bean seedlings, what a waste of trees, at this time people have not realized that afforestation will not damage trees.

So Lu Caiqing and Song Ziyu stepped forward and said, "Uncle He! Uncle! ”

When Uncle He saw Lu Caiqing taking the initiative to greet the old man, he was stunned, and just as he was about to introduce him, he was stopped by the old man's eyes, and Uncle He stopped talking.

"Girl! You are eyeing this vegetable garden during the day, you are not idle at night, what do you want to do? ”

"Uncle! Look how inaccurate your description is! I still want to give you ideas to help you save some effort, but now a scoop of cold water is poured down, and I have no thoughts. After that, he pretended to be disappointed and walked back.

"Oops! Girl, come back, what do you just mean by what you just said to help us save our energy? This ancient vegetable garden is this planting method, can you still grow any tricks? ”

Lu Caiqing listened, turned around and said: "There are no tricks, but the branches you use are a little troublesome, do you have hemp rope at home, don't need to be too thick, you can replace your branch with that, save people and effort and protect the environment." ”

"Ring ...... Protect? What is it? He asked curiously and skeptically about what she was saying.

"It's eco-friendly! It literally means the act of protecting the natural environment for the sake of our nature and human well-being, and I mean that you want to take care of trees. Lu Caiqing patiently explained.

At this time, the old man also spoke: "I understand a little bit of what you said, and I don't understand a little bit, why do we have to take care of trees, there are so many trees in the woods, you can't cut them all, you are a fallacy." ”

The old man didn't agree with her point of view a little, Song Ziyu pulled Lu Caiqing and said, "Little daughter-in-law! Forget it, don't worry about people of their age, let's go look elsewhere? ”

"Why am I scheming with a handful of old people, you forgot what I told you, everyone is responsible for caring for trees, and it starts with everyone, and you can't just tell them the truth because they are old people, uncle! Hobo! Do you know why flooding is rampant in the south? That's because people cut down all the trees indiscriminately. ”

"Girl! Don't talk nonsense! The flood was caused by the instability of the embankment, the heavy rain and the environment, and had nothing to do with the trees. The old man said confidently to me.

"You're talking about part of the reason, but you know that big trees have a good effect on soil erosion, so we have to plant trees, because trees have a huge root system like a canopy, and they can hold the soil like giant hands. The water of the soil that is caught is constantly absorbed and stored by the tree roots. Big trees also have the effect of preventing wind and fixing sand, so we must take care of them. Lu Caiqing said a lot about the benefits of afforestation.

Uncle He and Uncle He looked at each other, and Uncle He said with a smile: "You girl, you have said so many benefits of afforestation in one breath, but it sounds really interesting." You little mouth can really say, what do you think we are doing in front of you? ”

Lu Caiqing didn't care about their views on their own afforestation, anyway, the ideas of this world have not been as deeply rooted as the nine-year compulsory education in modern times, and she can only lead by example, and she can't control how many people she can influence.

Hearing the old man ask himself how to use hemp rope, he briefly introduced the method, that is, to set up two fixed wooden stakes at both ends of the bean horn ridge, and then tie several thicker hemp ropes on it, and then nail short sawdust next to the bean seedlings one by one, tie the thinner hemp rope from the bottom to the highest end, and then slowly wrap the vine of the carob seedlings by hand, and it will take the initiative to coil up and grow.

Lu Caiqing was afraid that they didn't understand, so he rolled up his sleeves and started to study with them, Song Ziyu didn't understand it at first, but then the big frame was laid, and he did it easily. As soon as the masterpiece of the four came out, several workers who had finished watering also came to help, and everyone worked together to support a long row of bean racks.

Everyone nodded at a glance, praising Lu Caiqing's simple method, looking at it in a regular and orderly manner, Uncle He couldn't stop nodding and giving Lu Caiqing a thumbs up, and the old man smiled and said, "Girl!" It's really yours, so it really saves a lot of branches, in fact, this long and straight branch really wastes a lot of trees, and I will follow your method tomorrow. ”

"It's not early! It's getting dark, let's go back and rest! He Bo looked at the sky and said to a few people.

Lu Caiqing and Song Ziyu nodded when they heard this, Lu Caiqing wiped his clothes with his hand and supported the old man and said, "Uncle! In fact, I see that you and Uncle He are not young, this kind of work will be left to young people to do, if you like it, you can come and see, the legs and feet are not flexible when you are old, if you are injured, your children will be worried and sad! ”

The old man raised his eyes and looked at Uncle He, and said with a smile: "I just like to do it myself, and I eat the vegetables I grow by myself to taste." ”

"Look at you, you are tired and out of breath just now for this simple work, I think Brother Lin asked you two elders to work in this courtyard, today I look at Brother Lin's respectful demeanor towards Uncle He, I know that his original intention must be to let you come here to recuperate, you can play chess if you have nothing to do, practice Tai Chi and what to nourish your body, I think Brother Lin arranged you here, it should be this meaning." Lu Caiqing's love overflowed, and he said his thoughts with feeling.

Song Ziyu also agreed with Lu Caiqing's point of view, he didn't have any concept of master and servant in his mind, so he stepped forward to support He Bodao and said, "What the little daughter-in-law said makes sense!" In the future, you will do less menial work and just see. ”
