In fact, Marin didn't know that sweet potatoes have seeds. Not only sweet potatoes have seeds, but potatoes also have seeds. However, the average farmer grows sweet potatoes and potatoes and does not use seeds for propagation.

Because, after a long period of cutting and vegetative propagation, the seeds of both sweet potatoes and potatoes have degraded. Even if the seeds are retained, the germination rate is not high.

Moreover, when propagated by seeds, it is easy to mutate. For example, sweet potato varieties that were originally high-yielding are prone to mutation into low-yielding varieties. On the other hand, if you reproduce vegetatively with dices, you can ensure stable yield and quality.

How to say it, seed propagation is similar to the marriage of a human man and a woman, and the children born may be like men, women, or both, but they inherit the shortcomings of both men and women......

Asexual reproduction, on the other hand, is similar to cloning. The cloned offspring are very similar to the mother, the gender is also the same, and the appearance is similar. Of course, human cloning is against morality, but vegetatively reproduced sweet potatoes and potatoes are fine. After all, that's food, and who cares what sweet potatoes and potatoes think?

……

In fact, sweet potatoes and potatoes also bear fruit. It's just that when Marin's parents in the previous life cleaned up the weeds in the sweet potato field, they also pinched off the flowers by the way.

Why? Because flowering and fruiting are very nutritious for the plant. Let's put it this way, rice blossoms and bears fruit, and finally all the nutrients are gathered into the rice, while the rice straw becomes yellow because the nutrients are exhausted, and the same is true for wheat......

Many people think that rice is the seed of rice, but it is not. Actually, the seed of the rice, which is the little spike of the rice. As for rice, it is actually the aggregation of nutrients from the whole rice, which is used to provide nutrients to the small spikes on this chaff.

In other words, the whole rice grain is actually equivalent to the nutrient solution in the medium of the small tip on the rice husk, providing enough nutrients for the small tip to sprout and grow.

The same is true of wheat, where the seed of the wheat grain is actually the inconspicuous little bump at the top of the hollow strip, which is the core of the wheat seed. And the whole wheat grain, like rice, is a nutrient solution in the medium that provides nutrients to the seeds, also called the endosperm. In other words, the flour we often eat is actually mainly the endosperm of wheat seeds.

Therefore, rice cannot grow when it is planted. Rice can only be grown by planting it in shells. And the sharp tip on the rice husk is the real rice seed.

You also need to pay attention when you are stockpiling food. If the drum or the wheat grains are insected, they may not be used as grain seeds. Because, these bugs are chicken thieves, specializing in gnawing on the small spikes of rice and the small bumps on the wheat grains. If this happens, the seed will be wasted and will no longer be able to grow rice and wheat. So, the farmers hate this bug very much. Because, they specifically gnaw the core part of the rice and wheat seeds, so that the rice and wheat seeds are "cut off". If you plant this kind of rice and wheat that have been plagued by insects, you will definitely not get any harvest. In modern times, it was fine, but in ancient times, it was the end of starvation of the whole family......

……

Sweet potatoes are not the same as potatoes, though. Because, sweet potatoes and potatoes, people don't want their seeds, but their stems. So, it's okay not to bloom and bear fruit.

Moreover, flowering and fruiting absorb most of the nutrients of the plant, affecting the yield of sweet potatoes and potatoes. Therefore, savvy farmers will not allow sweet potatoes and potatoes to blossom and bear fruit. Often, when weeding, the flowers are pinched by the way.

Although Ma Lin was a rural child in his previous life, most of them were educated in school, and he would only help when the agricultural work was most complicated, such as spring plowing and autumn harvest (also known as big busyness). Rural schools also have a special kind of holiday, called "busy vacation". That is, during the summer and autumn harvest seasons, the children are allowed to go home to help during the holidays.

Because, as far as the countryside is concerned, rice and wheat are all to be "rushed", for fear that the harvest season will rain, causing the crops to rot in the ground. Children can't go home and can't participate in the harvest, but they can help with the cooking. In this way, a laborer can be freed to participate in the harvest. In addition, teachers in rural areas also need to go home to participate in the harvest. Especially the male teachers, they are the main force of farm work. The ones who really need to take a break are actually those rural teachers. The children come home and help with the cooking, or gleaning the ears of wheat in the summer.

Of course, this is in the nineties. Because, at that time, most of the farmers still harvested by hand. After entering the 21st century, harvesters are used, which are faster than others, and some imported harvesters also have their own drying functions. In addition, after the 21st century, most of the young and middle-aged people in rural areas have gone out to work, and most of the people who stay at home are elderly, and they are unable to harvest manually, so they can only rely on machines.

……

In other words, although Marin was a rural child in his previous life, he would only help when he was busy. Usually when his parents go to the ground to pull weeds and pinch off the sweet potato flowers by the way, he can't see it. So, he hadn't seen sweet potato flowers and seeds. When he became an adult, he went to college and went to work in the city, so it was even more invisible, and it was not unusual not to see sweet potato seeds.

Although Marin had never seen sweet potato seeds, he also knew a lot about agriculture. For example, when rice and wheat are ripe, nutrients are collected into the seeds, and then the plants turn yellow and die.

So, he frowned and asked:

"How are those seed-bearing sweet potatoes growing?"

Gaudard thought about it, and couldn't think of why. But Ben, who had not yet set out, replied:

"Like...... It seems that the yield of sweet potatoes that have seeds will be reduced...... The sweet potatoes that produce are shriveled...... But instead of waiting for the seeds to be harvested, the yield is higher and the sweet potatoes are fuller......"

Aben was the first governor of Panama City, and there were many sweet potato fields around Panama City.

Marlin understood in an instant - it seems that flowering and fruiting really affect the yield of sweet potatoes and potato tubers. He was already wondering, why the yield of sweet potatoes per mu is only about 1,000 catties now, even if three fertilizers are used. It turns out that the nutrition is robbed by the seeds......

So, he ordered:

"When you plant sweet potatoes in the future, you will pinch them off when you see them blooming!"

"Huh? Pinch off the flowers, won't you be able to bear seeds? Ghoillard was a little stunned. Because, not allowing seeds to be born, this is a bit shocking. After all, Europeans have not yet had such a habit.

"Let you pinch it, what's the nonsense?" Marin dissatisfied.

Then, he added:

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

Gaulard had no choice but to nod, he had already decided, take out half of the sweet potato field, and conduct a pinching experiment to see the effect. He didn't dare to take any chances, after all, the Panamanian region now relies on sweet potatoes as its staple food. Although Ghoillard himself and some of the colonists did not eat sweet potatoes every day, the black slaves relied on sweet potatoes for their survival......

After arranging these things, Marin took the men and horses who needed to go to Daming, boarded 10 warships, sailed into the Pacific Ocean, and sailed all the way west to the Ming Empire...... (https:)
