Ming Dynasty: Teaching The Prince Dragon-Slaying Skills At The Beginning

Chapter 744: Potato Detoxification And Prevention, The Difficulty Of Promoting Planting [Please Subs

After distributing potatoes and the "Potato Planting Manual" to a group of villagers over fifty years old, Yan Longan then distributed potatoes to the villagers who passed the three hundred core Chinese character assessment.

After all the villagers who were supposed to get potatoes and the "Potato Planting Manual" received potatoes and the "Potato Planting Manual", Yan Longan taught the villagers of Xiahe Village how to plant potatoes in the center of the square. Precautions.

"There is an important reason why potatoes can produce an output of 20 to 30 shi per mu, and that is that a potato can be grown by cutting it into several pieces."

"In other words, it's just one potato that can actually be grown as several potatoes."

"So when the number of potato seeds is insufficient, we can get more potato seeds by cutting potatoes into pieces."

"How many pieces a potato can be cut into depends on how many bean sprouts there are on it.

"In addition, when potatoes are cut into pieces, whether they have top buds, side buds, or tail buds, the yield is also different."

"The yield of potato tail buds after they mature is very low, only one-third of the top buds or side buds, so generally we have to remove the tail buds."

"Generally speaking, seed potatoes weighing less than 50 grams can be sown as whole potatoes, with only the tail buds cut off.'

"For seed potatoes of average weight, cut the seed potatoes lengthwise from the top to the navel, ensuring that each piece has one to two buds."

"For seed potatoes of more than 150 grams, cut the seeds diagonally from the tail into several small triangular pieces in the longitudinal direction according to the number of bud eyes."

"The incision should be close to the bud eye, which can stimulate early germination and facilitate early emergence; when cutting, you should pay attention to making the wound as small as possible instead of cutting the seed potatoes into pieces."

As Yan Longan spoke, he picked up potatoes one by one and demonstrated in public how to cut potatoes into small pieces.

More than 2,000 villagers in Xiahe Village couldn't help but move their feet and crowded towards Yan Long'an as they watched.

There were even low and noisy voices of complaints, dissatisfaction, and low drinking.

Seeing this, Yan Longan quickly said:

"Don't crowd, don't crowd. What I just said is included in the "Potato Planting Manual" sent to you!"

"In addition, after I finish speaking later, I will also teach you how to cut potatoes into cubes!"

"Now you just listen to me briefly and carefully to get a preliminary impression."

"If you have any questions that you can't see or see clearly during this period, you can ask me later - ask me in person!"

After hearing Yan Longan's comforting words, the villagers of Xiahe Village stopped pushing forward.

"In addition, the cutting knife should be disinfected with boiling water or alcohol before cutting into pieces."

"If there is alcohol, then after each cut, soak the knife in alcohol for about one-third of a quarter to disinfect it."

"If you don't have alcohol, prepare a pot of boiling water on the fire and a pot of cold water."

"After each cut, put the knife into boiling water, soak it for about a third of a quarter to sterilize, and then put it into cold boiling water to cool down.

"Then take the knife and continue to cut the potatoes into pieces, and repeat this cycle until the entire field is cut into layers."

"In addition, if you encounter diseased potatoes during cutting in the future, you must immediately change to another knife to avoid cross-infection of germs through the cutting knife.

"Because there are many diseases related to potatoes that can also be spread through knives."

"Of course, the potatoes now distributed to you by the imperial court are normal potatoes with no diseases, so don't worry."

When they heard Yan Longan talking about diseased potatoes, some people from Xiahe Village in the crowd asked loudly:

“Can potatoes also have diseases?!!”

Yan Longan looked at the source of the sound and explained gently:

"Potatoes are also crops. Just like wheat and rice today, it is natural that diseases will occur."

"Once a diseased potato is discovered, it must be uprooted immediately and thrown into the fire."

"Otherwise, if we keep it, one potato may be infected with the disease, but in a few days, the entire field of potatoes will be infected with the disease, and then the potato harvest in the entire field will be ruined because of this!"

"It may even involve the potatoes planted by other people being infected with the disease, causing everyone's ugly beans to be harvested as a result!"

"So in this regard, we must not be negligent!"

At the end, Yan Longan looked serious.

Their dean, Nongsheng Shennong, once told them a story about potato diseases.

There is a small country overseas. Because it is interested in the high yield of potatoes, it vigorously promotes potato cultivation across the country.

However, I did not expect that potato blight, which is prevalent in other small countries, was also introduced to this small country.

As a result, all potatoes in this small country were infected with the so-called potato blight, and nearly all of the country's potato harvests failed, resulting in a nationwide famine!

Nearly two million people in this small country starved to death, and the entire country was almost wiped out because of the potato blight!

In the end, although the small country managed to survive, its vitality was severely damaged.

Therefore, when they grow potatoes in the Ming Dynasty, they must learn lessons and experience and try to avoid this situation from happening.

In fact, the story told by Yan Changqing and a group of peasant (bhfj) students was about the Great Irish Famine [commonly known as the Potato Famine] that occurred between 1845 and 1850 in a previous life.

In the 17th century, after Ireland was occupied by Cromwell of England, it became a colony of England.

At that time, two-thirds of Ireland's agricultural land was managed and planned by England, and was mainly used to grow wheat needed by England.

Only one-third of the land was left for the Irish to grow food.

Moreover, Ireland not only has a cold climate, but also has poor arable land, making it difficult to harvest most crops in Ireland.

The amount of cultivated land is small, the climate is cold, the arable land is barren, and so many people in Ireland must be protected from hunger.

Potatoes, which like cool and dry nature, are highly adaptable to soil, and have high yield per acre, have become the only choice for the Irish people.

So that one-third of the land was planted with potatoes, and almost no other food was grown.

However, what was unexpected was that potato blight, which was prevalent in Europe at that time, spread to Ireland.

Potatoes throughout Ireland are basically infected with this virus, and potatoes grown in Ireland are withering on a large scale.

Millions of Irish people fell into famine. What was worse was that England did not take any rescue action during this famine [directly preventing the epidemic of these ten Irish famines.

At that time, all the wheat produced in Ireland was still shipped to England, and not a single grain could appear on the Irish tables. This undoubtedly exacerbated the impact of the Potato Famine on the Irish.

During this five-year famine, the population of Ireland under English rule dropped by nearly a quarter, nearly two million people starved to death, and millions were forced to leave their homes and travel across the ocean to survive. .

It can be said that the potato famine left a lingering shadow on the Irish people.

At the same time, they were deeply resentful of England's inaction and unwillingness to save the country at that time.

Like Yan Changqing's previous life, the relationship between Ireland and England was so rigid, and a large part of it was caused by the historical factors left behind by the ten potato famines.

“So how should we prevent potatoes from suffering from diseases?!!”

There were also villagers from Xiahe Village in the crowd asking.

"We have written down the common diseases and insect pests in potato planting and how to prevent them as much as possible in the "Potato Planting Manual."

"For example, potato leafminer damage."

"March to April is the peak period for the damage caused by the spotted leafminer. After the damage caused by the spotted leafminer, the plant leaves lose a lot of water through evaporation through the egg-laying feeding holes, which accelerates the death of the potato plant leaves.

"

"If a large number of adult insects migrate into the potato field and cause damage, if prevention and control is not done, it will only take seven to ten days to damage the entire potato field and cause it to die."

"The prevention and control method is to adjust the crop planting structure!"

“Plant less or no crops sensitive to leafminers such as broad beans in the spring potato planting area to reduce the number of insect sources; focus on the prevention and control of potatoes during the sprouting period and potato tuber expansion period in spring, taking into account both adults and larvae. Mainly to prevent adult insects.”

"Another example is the degeneration and poisoning disease of potatoes, which is divided into physiological degeneration and viral degeneration."

"The physiological degradation is mainly caused by the incompatibility of the planting environment."

"For example, if low-temperature-tolerant potato varieties are planted in high-temperature seasons, northern potato varieties are introduced to the south, and spring potatoes are cultivated in summer, the potatoes may not adapt to the external environment."

"Viral degeneration is mainly caused by viruses such as leafroll virus and mosaic virus."

"These poisonings and degradations will reduce potato yields, or even lead to harvest failure or failure."

"The methods to prevent potato degradation are: first, choose virus-resistant varieties, free of diseases and insect pests, prime-age potatoes, and potato pieces with strong vitality as potato seeds."

"Potato seeds with strong anti-virus capabilities can minimize the harm caused by viruses to companies when they are troubled by viral diseases.'

"At the same time, do not use potatoes that have been exposed to high temperatures or frozen at low temperatures as seeds. Try to use virus-free potato seeds."

“Second, when introducing potato seeds, try to introduce them from high-altitude areas to lower-altitude areas. The higher the altitude, the less likely potato varieties will degrade.

"Even if you save potato seeds in plain areas, you should choose potatoes with strong plant growth and obvious disease resistance and stress resistance as seeds.'

“Try to use virus-free potato seeds, or collect seeds from sexually propagated potatoes and cultivate the seeds, which can overcome the disadvantages of asexual reproduction.

"The way I just cut the potatoes into pieces is actually a process of detoxifying the king beans."

"Because the closer the potatoes are to the stem tip, the less virus they contain, and the less likely they are to get diseases when they are planted."

"Third, save seeds, choose late-sown potatoes, and prepare potato fields reserved for seeds. It is best to have a certain distance from commercial potatoes."

"At the same time, timely prevent and control aphids and other sucking mouthpart pests to reduce the spread of viruses by insects."

"Fourth, if relatively few potato virus-infected plants are found, they can be removed in time, taken out of the field, and burned."

Yan Longan patiently told the story.

It has been more than four years since Wanmin Agricultural College started planting potatoes.

Two harvests a year means eight harvests, and Yan Longan and his group of agricultural students also personally planted potatoes eight times.

During the eight potato plantings in the past four years, they have gained rich experience in dealing with various common viruses and pests that may be encountered in potato planting.

And these experiences are time and time again

They added several places to the "Potato Planting Manual". It can be said that the "Potato Planting Manual" now available to ordinary people is the same as the original "Potato Seeds" compiled by Yan Changqing.

Planting Manual is very different.

The first edition of "Potato Planting Manual" compiled by Yan Changqing only taught others how to grow potatoes in the simplest way.

And now the book in the hands of ordinary people can be called the 4.0 version of the "Potato Planting Manual". In addition to teaching others how to grow potatoes in the simplest way,

outside.

At the same time, it also records various problems that may be encountered in the process of growing potatoes, as well as related solutions.

And as time goes by, a group of agricultural students have become more and more sophisticated in their research on potato cultivation.

In the future, the "Potato Planting Manual" will also have a 5:00 version, a 6:00 version, etc., which will continue to be added, deleted, modified, and compiled.

Looking at the villagers in Xiahe Village who had uneasy expressions on their faces after listening to what he said, Yan Longan comforted him in a gentle voice:

"Don't worry, the potatoes you are holding are non-toxic potatoes selected by our Agricultural College, and the problems just mentioned will not occur for the time being.

"And you can only plant one or a dozen potatoes at most right now, and you don't need to plant them specifically in the fields."

"You can just plant it directly in the vegetable field in front of your house or behind your house, or you can just fill a big tank with soil and plant it in the tank."

“When the number and scale of potato planting increases in the future, agricultural students from our Agricultural Research Institute will also go to each village every day to inspect the fields where potatoes are planted.

Help you determine which potatoes are affected by the disease and try to prevent you from suffering large-scale Biyou disease. "

"The imperial court and we will do our best to help you grow good potatoes!!!"

Again, it is not easy to promote the cultivation of a new crop.

Each type of crop has its own unique character, and also has its own planting matters that require attention.

If potato seeds are directly distributed to the people, and then the people use them to plant them, then various planting problems will inevitably arise in the end.

And if ordinary people want to solve these planting problems, or want to gain experience in solving these planting problems, they will inevitably pay a heavy price in the end!

And at such a painful price, I don’t know how many people’s blood and tears it cost!

Things like this are what Yan Changqing doesn't want to see, and what Zhu Yuanzhang doesn't want to see.

Either don’t do it, or do it as well as possible!

Since it was decided that the imperial court would promote potato cultivation, it was natural that the imperial court would find ways to minimize the various risks that the promotion of potato cultivation would bring to the common people!

In this way, a good thing will not be turned into a bad thing.

For example, the reason why Ming Dynasty chose this year to start distributing potato seeds to the people all over the world to promote potato planting.

In addition to the insufficient amount of potatoes stored, the insufficient number of masters responsible for educating the people in every village in the world, and other factors.

There is also a very important reason, that is, this year the first batch of agricultural students from Wanmin Agricultural College has reached the age of graduation.

After the first class of agricultural students graduate, most of them will return to counties across the country to run agricultural research institutes and be responsible for guiding people in potato planting in each county.

By then, agricultural students who have planted potatoes eight times in four years and have rich experience in dealing with various problems in potato planting can "give the most direct advice to the people in the early stages of planting potatoes."

Guidance and assistance.

In this way, the risks and problems faced by ordinary people in planting potatoes will be greatly reduced and solved.

This is also the reason why the imperial court dared to choose to promote large-scale potato planting all over the world this year.

The original uneasy and worried expressions on the faces of the villagers in Xiahe Village who were comforted by Yan Longan gradually disappeared. They relaxed again and continued to listen carefully to Yan Longan.

Long An talks about various aspects of growing potatoes.

At this moment, the sun was setting in the square, and the shadows of Yan Longan, who was speaking seriously, and the villagers of Xiahe Village, who were listening seriously, and the government officials gradually lengthened.
