"What Cher wants to say is that the vine I first found seems to be very strange, and I didn't see it bloom.

And this potato is only three months from germination to ripening. Xue'er tried her best to narrate her discovery from the perspective of a child, and sure enough, Dong Changhe never doubted her during this period.

Xue'er said these words for two purposes, one is to pave the way for her to find sweet potatoes in the future, and the other is to make Dong Changhe realize that the growth period of potatoes is short, and he can now rest assured that he can boldly do experiments!

It's possible to store potatoes in a cellar, but what if they sprout now once they can't withstand the heat? In winter, the temperature in the cellar will be lower, and the potatoes may freeze by then, so she tossed for so long and tossed in vain?

She regretted it now, she should have planted potatoes later.

Of course, she didn't lie, in order to let herself discover the potato and sweet potato, so as not to arouse Dong Changhe's suspicion, she did lead the sheep to those two places.

Xue'er's words attracted Dong Changhe's attention and deep thought, he thought for a while and asked, "Xue'er can you remember clearly?" Is it true that the potatoes have finished flowering and fruiting in three months? ”

Xue'er nodded her little head heavily, and said with certainty: "Dad should know that Xue'er's memory is very good, and I observe everything very carefully." That's right! ”

Dong Changhe was happy, and he happily said to the Yun family: "We can boldly experiment now, if it is really as Xue'er said, then the value of this potato will be even higher!" ”

He hesitated before, for fear that he would not succeed in the test and harm such a good thing, but now he is a lot more relieved.

As for why such a good thing would be discovered by a child, it is not difficult to understand. He himself had done this when he was a child. I found something new in the mountains, dug it up, and asked my grandmother what it was and if I could eat it.

He did not doubt the reason why potatoes grew here, and it was common for plant seeds in the mountains to be taken to the periphery by small animals to take root and sprout.

Back to the book, just imagine, planting two seasons a year, one season per mu is 2,000 catties, and two seasons of one mu is 4,000 catties.

Four thousand pounds! In this era, the yield of sorghum per mu was no more than five stones, that is, five hundred catties. The growth cycle is also relatively long, generally around five months.

The yield of millet and millet, that is, millet, or millet is only a little more than three stones, that is, about three hundred catties to three hundred and fifty catties. It can only be planted once a year, and it takes six months from planting to maturity.

Millet and millet are commonly known as rhubarb rice, and the yield is similar to that of millet.

The yield of soybeans, that is, soybeans, is only three stones, and at most no more than four stones, that is, four hundred catties. Its growth cycle is one month less than that of millet, but it also takes five months.

The yield of rice, that is, rice, is the highest, and the highest yield of rice per mu in the north can reach eight stones, that is, eight hundred catties, and the general yield per mu is about seven stones.

Its growth cycle also takes seven to eight months here, which is a long time and naturally takes a lot of effort.

The wheat production cycle is only more than three months, but its yield per mu is low, at most only three and a half stones, that is, about three hundred and fifty catties.

Some people grow winter wheat, but it has a long growing cycle, usually eight to nine months. Many people are reluctant to plant.

Compared with the above, 4,000 catties is 40 stones, what kind of concept is this?

Dong Changhe doesn't dare to think about it now, if potatoes are popularized, then the current Daxi Dynasty can feed the people? How many sergeants can be fed?

He ignored what Xue'er said about sweet potatoes, and only thought about what kind of changes the potatoes could bring to him and Daxi Dynasty.

Thinking of this, he couldn't sit still, so he started the experiment with Yun's family, first taking out those potatoes with broken skins and putting them on the kang head to promote germination (he was reluctant to use those intact).

Then the couple took Xue'er to plant two ridges of land in the vegetable garden with eggs.

After pouring water, I gave up.

From this day on, Dong Changhe would go home every day, and before going to work in the morning, he would observe these sprouting potatoes, and he would personally go to the vegetable field to observe whether those sassy eggs broke the ground and sprouted.

After a few days, there was no reaction from the eggs in the field, but the potatoes that had sprouted sprouted sprouted.

This made Dong Changhe confirm what he thought in his heart.

On this day, he got off work early, found an inconspicuous place in the 300 acres of land where beans were planted, and pulled out the soybeans.

Then he borrowed a ploughing ox from Dong Changjiang, ploughed the land deeply, and finally went to the long ridge.

It is about an area of one and a half acres, and about 400 catties of potato seeds are planted.

Dong Changhe is worthy of being a very good person in agriculture, and he didn't need Xue'er to mention it, so he cut the potatoes into sprouts and sprinkled them with plant ash.

In the farmhouse grass ash is a good thing, it can do a lot of things.

For example, if you have a cut on your hand, you can stop the bleeding by applying plant ash. For example, plant ash can be used to soak clothes and be used as honey locust powder. For example, plant ash is sprinkled into the land, which can be used to prevent insects, can be used as fertilizer, and so on.

He didn't use Xue'er and Yun's help, but took matters into his own hands and was careful, for fear of breaking the potato sprouts.

Then carefully bury the potato cubes with the sprouts facing upwards. Finally fertilize and water.

The days passed in Dong Changhe's daily service to those potatoes, and a few days passed with his expectations.

In addition to worshipping ancestors in the midyear festival, his whole mind was spent on those potatoes.

Of course, he didn't delay going to work, but he came back early every day.

Although he also served the eggs with his heart, he just didn't sprout under his ardent expectations.

It's just that Dong Changhe didn't give up, and used two more methods to experiment.

In his opinion, the potato can sprout and grow on its own in the mountains, so it must not be because the rhizome was planted there, but because the birds must have brought its seeds to that place, so that it took root and germinated there.

Xue'er didn't stop him either, because the test came out of the real chapter, and this principle works well at all times.

She could only do as a six-year-old child. If she's eventful, the likelihood of her being exposed is too great. Age has always been her bruise.

Dong Changhe's experiment is still effective, and the eggs have also broken the ground and sprouted, but the germination rate is very low.

Time flies, and the grapes on the vines are almost ripe, and clusters of crystal clear green fruits hang there, like shining green jade, which makes people look forward to it.

Dong Changhe did not plant grapes for sale, but gave them away during the Mid-Autumn Festival.
