Chapter 1134: Pinch flowers without planting

In fact, Marin did not know that sweet potatoes have seeds. Not only sweet potatoes have seeds, but potatoes also have seeds. However, ordinary farmers grow sweet potatoes and potatoes, they will not use seeds to reproduce.

Because, after a long period of asexual reproduction of cut pieces, the seeds of sweet potatoes and potatoes have been degraded. Even if the seeds are kept, the germination rate is not high.

Moreover, when propagated with seeds, it is easy to change. For example, the original high-yield sweet potato varieties can easily become low-yielding. And asexual reproduction with cut pieces can stably guarantee the yield and quality.

How to say, seed reproduction is similar to the marriage of men and women. The children born may be like a man or a woman, or they may all be a little bit, but inherit the shortcomings of the man and the woman ...

Asexual reproduction is similar to cloning technology. The cloned offspring are very similar to the female parent, with the same gender and similar appearance. Of course, human cloning is unethical, and asexually reproduced sweet potatoes and potatoes are fine. After all, that's food. Who cares about sweet potatoes and potatoes?

...

In fact, sweet potatoes and potatoes also flower. It's just that when Marin's parents in his last life cleared the weeds in the sweet potato field, they also pinched off the blooming flowers.

Why? Because flowering is very expensive to consume the plant's nutrition. Let's put it this way, the flowering of rice results in the final gathering of nutrients into the rice paddy, and the rice stalks become yellow due to nutrient depletion, and so does wheat ...

Many people think that rice is the seed of rice, but it is not. In fact, the seeds of rice, that is, the little tip of rice. As for rice, it is actually a collection of nutrients for the entire rice, which is used to provide nutrients to the small spikes on the chaff.

That is to say, the whole rice grain is actually equivalent to the nutrient solution in the medium of the small tip on the rice husk, which provides enough nutrients for the small tip to germinate and grow.

The same is true for wheat. The seeds of wheat grains are actually the unobtrusive little bumps at the top of the concave strips, which is the core of the wheat seeds. The whole wheat grain, like rice, is the nutrient solution in the medium that provides nutrients to the seeds, also called endosperm. In other words, the flour we often eat is actually the endosperm of wheat seeds.

Therefore, planting rice can't grow rice. Only the husks can grow rice. The sharp point on the rice husk is the real rice seed.

It is also necessary to pay attention when storing grain normally. If the drums are beaten or the wheat grains are infested, they may not be used as grain seeds. Because these insects are very chicken thieves, specializing in eating the small spikes of rice and the small bumps on the wheat kernels. After being engaged in this way, even if this seed is used up, rice and wheat can no longer grow. Therefore, farmers hate this bug. Because they specialize in eating the core part of the rice and wheat seeds, so that the rice and wheat seeds are "broken sons." If the rice and wheat grains that had been harmed by insects were planted, the iron grains would not be harvested. Fortunately in modern times, in ancient times it was the end of starvation of the whole family ...

...

However, sweet potatoes are different from potatoes. Because, sweet potatoes and potatoes, people do not want its seeds, but its stems. Therefore, it does not need to bloom and bear fruit.

Moreover, flowering results will absorb most of the plant's nutrients, affecting the yield of sweet potatoes and potatoes. Therefore, knowledgeable farmers will not allow sweet potatoes and potatoes to bloom. When weeding is usually done, the flowers are pinched by the way.

Although Marin's last life was a rural child, most of them were educated in school. Only when farming is busy, such as spring farming and autumn harvest, will they help. The rural schools also have a special holiday called "Busy Holiday". That is, during the summer and autumn harvest seasons, the children are allowed to go home to help.

Because, for rural areas, rice and wheat are to be "grabbed", fearing that it will rain during the harvest season, causing crops to rot in the ground. Although children can't participate in harvesting at home, they can help with cooking. In this way, a labor can be freed to participate in the harvest. In addition, teachers in rural areas also need to take vacations and go home to participate in harvesting. Especially those male teachers, they are the main force doing farm work. Those who really need busy vacations are those rural teachers. The children go home, at most help cooking, or picking wheat ears or something in summer.

Of course, this was something in the 1990s. Because at that time, most farmers still used manual harvesting. After entering the 21st century, all harvesters are used, which is faster than others, and some imported harvesters also have their own drying function. In addition, after the 21st century, most of the young and middle-aged people in rural areas went out to work, and most of them stayed at home with elderly people, who were unable to harvest by hand and could only rely on machines.

...

In other words, although Marin's last life was a rural child, he only helped when he was busy. He usually couldn't see when his parents pulled down the weeds and pinched the sweet potato flowers. Therefore, he has never seen sweet potato flowers and seeds. After he became an adult, he went to college and went to work in the city, which is even more invisible. It is not uncommon to see sweet potato seeds before.

Although Marin has never seen sweet potato seeds, he also knows a lot about agriculture. For example, after the rice and wheat are mature, the nutrients will converge into the seeds, and then the plants will turn yellow and die ~ www.wuxiaspot.com ~ So, he frowned and asked:

"How about the sweet potatoes that are seeded?"

Gorard thought about it, and some couldn't figure it out. But Arben, who had not set off yet, replied:

"It seems ... it seems that the yield of seeded sweet potatoes will be reduced ... The resulting sweet potatoes are more shrivelled ... but the harvest is not waited until the seeds are finished, but the yield is higher and the sweet potatoes are fuller ..."

Aben was the earliest governor of Panama City. There are also many sweet potato fields around Panama City. Aben used to go on field inspections, but he knew a little.

Marin understood it instantly-it seems that the flowering will really affect the production of sweet potatoes and potato tubers. He was already strange, why now the sweet potato yield is only about a catty per mu, even if three fertilizers are used. It turned out that the nutrition was taken away by the seeds ...

So he ordered:

"Put sweet potatoes in the future and pinch off when they see flowering!"

"Ah? Pinch off the flowers, isn't it possible to seed?" Gorard was a little surprised. Because, not to let the seeds come, this is a bit shocking. After all, Europeans have not had this habit.

"Just let you pinch, pinch it?" Marin said dissatisfiedly.

Then he added:

"After pinching flowers, count the latest yield per mu of sweet potatoes!"

Gorard nodded. He had decided to take out half of the sweet potato field and conduct a pinch test to see the effect. He didn't dare to take risks. After all, the Panama area now depends on sweet potatoes as staple food. Although Gorard and some colonizers do not need to eat sweet potatoes every day, those black slaves rely on sweet potatoes to maintain their lives ...

After arranging these things, Marin took the men and women who needed to go to Daming, boarded 10 warships, sailed into the Pacific Ocean, and headed westward to the Daming Empire ...
