Chapter 681 676. Sweet Potato Cake

I clearly told her that Tang Dun Dun was in short supply only last year, but there will be plenty this year and even more next year. In a few years, it will become a very common sweet potato and enter thousands of households.

Just like Sunshine Rose grapes.

In 18, the price was 300 yuan per pound, and a string was sold at a high price of 980 yuan.

How about this year? Only 10 yuan per pound.

By next year or the year after, maybe three kilograms will cost ten yuan.

It only took four or five years for the price to go from sky-high to ordinary.

Tang Dun Dun will probably do the same, so there’s no need to get so excited.

It's useless to say it.

Teacher Xue seemed even more excited.

Well, someone is watching the kids.

Luo Yihang handed little Luo Qi to Teacher Xue with confidence.

Wang Shaopeng and I went to do the real work.

"Today we plan to harvest 50 acres first to see if there is any difference in the total output compared to the measuring points." Wang Shaopeng said, pointing to the area being excavated.

"What was the output at the previous measurement point like?" Luo Yihang asked.

The measuring points are where a small piece of the crop is harvested from a few selected locations after the 700 acres are planted, to calculate the average yield.

"2249 kilograms, average yield per mu." Wang Shaopeng replied.

Luo Yihang was surprised for a moment, "2249, it has increased a lot, my place was and a few dozen last year."

"Well, we improved some planting techniques. The sweet potatoes are small, so we tried to remove three and leave one when thinning them out, and the effect was good."

Thinning out seedlings is also called thinning out seedlings.

That is, when the sweet potato seedlings grow to about 10 centimeters, adjust the planting density and remove the overcrowded ones or those that are not growing well to avoid competing for nutrients and to retain growth space.

Remove three and keep one, which means that instead of removing four plants, one should remove three plants to increase the planting density.

The output has increased by 10%, which is a very good effect.

"The Mianyang Academy of Agricultural Sciences is more radical. In addition to thinning and dense planting, they also tried to control vine growth a week in advance. The effect is very good. The yield per mu is 2,400. The crops grow very evenly and are of good quality." Wang Shaopeng mentioned the achievements of the Academy of Agricultural Sciences again.

Vine control means controlling the growth of vines to balance the growth of stems, leaves and tubers, avoid the restriction of sweet potato tubers caused by excessive growth of sweet potato vines, and avoid premature aging.

Since Tang Dun Dun synthesizes less starch, most of the tubers are stored in the form of sugar and organic matter. It omits one step and the amount is relatively small.

There is no need for so much organic matter produced by photosynthesis, and controlling the vines in advance will help increase production.

It is just as the Mianyang Academy of Agricultural Sciences said.

The level of output is determined by variety, which is one aspect and determines the baseline.

Whether the yield is higher or lower than this line depends on the soil, light, climate, pest and disease control, and planting techniques.

If you fully understand its temperament and prescribe the right medicine, it is possible to increase the yield by 70% to 80% compared to when it was first cultivated.

It's only been one season, but production has already increased by 20%.

Then I saw a few trucks coming and stopping where the sweet potato vines were piled.

Wang Shaopeng shouted, and several people came out from the field, took forks, loaded the sweet potato vines onto the truck and took them away.

The car was called from a nearby pig farm.

The sweet potato vines that were dug out were not wasted, they were all used to feed the pigs.

Watching it.

Little Luo Qi and two elementary school girls came running over in a hurry.

Each person held two sweet potatoes in his hand.

He ran to Luo Yihang and said, "Brother Hang, help me peel the skin."

I made friends so quickly.

Luo Yihang felt his body and found that he didn't have a knife with him.

Wang Shaopeng smiled and said, "The ones that are just dug out are not tasty. Can brother give Qiqi some delicious ones?"

Luo Qi shook her head and answered seriously, "This is delicious. It's sweet."

But the little girl knows how to eat. She will always have a share of any good things Luo Yihang has.

I go to Ping'angou often and have eaten and seen the real food there.

These raw sweet potatoes were the ones that her father took her to the fields to dig out and peeled and shared with her when she came to play.

Wang Shaopeng chuckled.

He said mysteriously: "Brother, here are some sweet potatoes that are sweeter and more delicious. Wait a moment, let brother get them." Then.

Wang Shaopeng took Luo Yihang to the warehouse and looked at the well cellar.

The so-called well cellar is a well dug deep in the ground, but without water.

The well mouth is about one meter in diameter and five or six meters deep. A layer of sand more than ten centimeters thick is laid at the bottom to isolate water vapor.

Put the harvested sweet potatoes in, fill it up to 70% to 80%, and leave some space around for ventilation.

The temperature of this well can be controlled at around 15 degrees, which allows for long-term storage.

The second is to go through a "saccharification" process on the sweet potatoes, which can increase their sweetness a lot.

"Can it be increased further?" Luo Yihang felt fresh again.

Last year, the sugar candies were directly placed in the cold storage after being harvested and sold right away.

No sugaring whatsoever.

Wang Shaopeng opened the first well cellar with great interest and took out a bag of sweet potatoes.

I found another fruit knife.

The two of them peeled a piece and ate it raw at the entrance of the well.

Tangdundun sweet potatoes have less crude fiber, feel more watery, and have a sweet and crispy texture.

It is even more delicious after saccharification and is sweeter than last year.

This method is not bad, steal it, steal it.

Oh, that's interesting, I can make a snack.

Wang Shaopeng took the bag of sweet potatoes and went to the field to peel raw sweet potatoes for little Luo Qi and the other children.

Luo Yihang also took a bag and went to the kitchen, planning to fry some sweet potato pancakes to try.

Don’t make the kind where you mash sweet potatoes into balls and then press them into pancakes; that’s too troublesome.

Make it simple.

Peel the sweet potatoes, cut them into small dices, add some flour and water and stir them so that they can stick together and not fall apart.

Use a slotted spoon to scoop a little and fry in the oil pan.

Be careful to use medium heat, and don't let it burn or fall apart.

Simple, convenient, fast and delicious.

When I was a child, they sold for 50 cents each at the school gate, and a large group of children would gather around them after school every day.

I miss it so much.

Luo Yihang quickly prepared a large batch and distributed a few to the aunties in the cafeteria.

He put the rest into a basket, covered it with a cloth to keep out the dust, and carried it back to the field.

At this time, all the elementary school students who were doing extracurricular activities were not picking sweet potatoes in the fields.

Who would want to work when there is something delicious to eat?

The canvas bags filled with sweet potatoes were thrown on the ridges of the fields.

They lined up in two rows.

A group of people lined up to ask Teacher Xue to wipe their hands with wet wipes.

After wiping it clean, he quickly ran to the back of the other team and looked forward cautiously.

At the front of the team, Wang Shaopeng took a small knife and peeled the sweet potato. After peeling, he cut it in half and gave each child half a sweet potato to eat.

There was a crackling sound on the ridge of the field.

The little kids were grinning as they chewed them.

When little Luo Qi saw Luo Yihang, she jumped over and held up her piece of raw sweet potato that was covered with teeth marks.

"Brother Hang, the sweet potatoes from Brother Wang's family are sweeter than ours."

Hey, Brother Wang’s call is so affectionate, even sweeter than ours.

Can't stand it, absolutely can't stand it.

Luo Yihang's childish desire to win suddenly emerged.

He lifted the cloth on the basket and showed it to Luo Qi, "The ones I have here are sweeter, crispy and fragrant. Take one and give one to the teacher as well..."
