Hearing the old man say this, Yang Chunyan realized a problem, that is, people in this era don't know about sweet potatoes, let alone know that this 'thing' is actually edible, and it is a treasure from beginning to end!

"Old man, can you give this to me?"

"What do you want this thing for?" The old man was puzzled, "You can't eat it, you can't exchange it for silver taels, it's dirty and hard, if you like to take it." ”

"Thank you then." Yang Chunyan put away the sweet potatoes and asked the old man, "Old man, do you have more sweet potatoes there?" ”

"Not much, but if you dig into the mountains, you might be able to find a few." The old man did not hesitate, and said directly, "If you find it, I will send it to you as well." ”

The next day, he brought rice and three sweet potatoes.

Yang Chunyan bought it with a smile, set up a rice bucket in a corner of the grocery store, and poured the collected rice into it separately after polishing, with different prices.

When the shopkeeper saw this scene, his lips rose slightly, "The shop has never sold rice, although I don't know what the business will be, but just looking at the color of this rice, it is really beautiful." ”

Since it is a grocery store and sells miscellaneous things, it is also good to open up a container for food.

"The food grown by the people, those ladies can't look at it, so I bought it, processed it cleanly, and put it away, try it first." Yang Chunyan hooked her lips and chuckled, no matter what era it is, it can't change the fact that the rich are poor and the poor can't change the same thing, placed in different places, there is a certain difference.

After finishing the shop, Yang Chunyan carefully packed four sweet potatoes and went home.

There is an open space in the backyard of the Huo family, and some vegetables are usually planted, and there is just a small piece of land that has been harvested, which she can use to grow sweet potatoes.

This land has a low water level, sufficient water sources, convenient drainage and irrigation, and loose and fertile soil, which is a good choice.

The thought that the sweet potatoes grown can be steamed, boiled, roasted, and the sweet potato leaves can be stir-fried and eaten, these are all delicious, and no one notices.

If a large area of sweet potatoes is grown, it is then processed......

Yang Chunyan's eyes suddenly lit up, business opportunities, absolute business opportunities.

It's just that this season is not a good season for planting sweet potatoes, the weather is getting colder and colder, if you want to grow sweet potatoes, you have to build a shed to get greenhouse vegetables.

It is excellent for the greenhouse to use hot-dip galvanized thin-walled steel pipe as the arch material, so that the strength is high, the wind and snow resistance is strong, the anti-rust performance is good, the light transmittance is high, the operation and management are convenient, etc., but the cost is high, and most importantly, there is no such material at all......

So what can be used instead?

"Sister-in-law, what are you thinking?" Huo Xiting didn't know when she came out, playing with a slender bamboo pole in her hand.

Yang Chunyan's eyes suddenly lit up, if bamboo poles and wood are used as arch materials, it is not only easy to build, but also low cost.

Thinking of this, Yang Chunyan looked at Huo Xiting, "Xiaoxi, where did you get this bamboo pole?" ”

Huo Xiting didn't understand what Yang Chunyan meant, she raised the bamboo in her hand and pointed to the thatched house at the corner of the yard, "My brother has been running outside for a long time, so he always reserves some firewood, sticks, and bamboo in advance and puts them in the firewood room so that they can be used at any time." ”

Yang Chunyan came to the firewood room, opened the door of the firewood room, and saw that there were indeed many inside, large and small, long and short, and couldn't help but sigh at Huo Yanshen's carefulness.

As a husband, is he considerate?

Suddenly, this question flashed through Yang Chunyan's mind, and after she came to her senses, she was secretly shocked, what was she thinking?

Retracting her thoughts, she entered the firewood room and began to look for some suitable bamboo poles and sticks.

"Sister-in-law, are you going to collect firewood for cooking?" Huo Xiting muttered, "But if that's the case, the size and length you choose are so even, and the fire should be so exquisite!" ”

Hearing Huo Xiting's words, Yang Chunyan couldn't help but smile, "Sister-in-law wants to make a greenhouse." ”

"Greenhouse?" Huo Xiting was puzzled, "What is that?" ”

"If it's done, you can grow out-of-season vegetables in it, and it's delicious when you make it into a delicacy." Yang Chunyan touched Xiaoxi's head and handed some bamboo poles to Xiaoxi, "Xiaoxi, can you help my sister-in-law move these to that open space?" ”

Although she didn't know what she was doing, when she heard the food, Huo Xiting immediately nodded, "Okay, I'll move it now." As he spoke, he began to help Yang Chunyan do things.

After the selection of materials was almost done, Yang Chunyan went to the house to get some soot, firewood knives, as well as thread and rope.

She set the north-south direction, and the exhaust vents were located on the east and west sides, because there were not many crops planted, and it was the first time to operate, so it was more prudent to build a small area first.

After determining the number and length of the greenhouse, the line was drawn, sprinkled with carbon ash, and then the gray line was drilled according to the predetermined skeleton spacing, and the bamboo pole was used to erect the arch.

Yang Chunyan tried her best to choose some uniform bamboo poles for erection, inserted the two ends of the bamboo poles, and fixed the two ends to keep the arch consistent and the height balance consistent, and set up a column at the highest point of the arch to support it, and inserted a wooden stick that can bear the load.

It took a long time to make the prototype, but then the question came again, what should be covered on the arch?

There is no film here.
