Today, the knowledge that everyone needs to learn is just biology. When a group of teenagers are holding hoes, baskets and other tools, those who don't know may think that this is a group of guys who are going to work in the fields. In fact, this is the biology course that Li Tianyang and they need to learn.

The person who taught everyone this knowledge was actually an old farmer in the village who had been planting land for decades, and his name was Wu Daoli. Over the years, under his teaching, everyone learned how to grow rice, wheat, cotton, soybeans and so on. We know when to weed, when to fertilize, when to interplant some soybeans, broad beans and other legumes to fertilize the land, and how long to leave a piece of land fallow to accumulate fertility.

Even many people in the village, including their husband Wu Daoli, were puzzled, did they still need to invite someone to teach something like this? Just find an old farmer to come out, that is not a treasure of these things, as long as you have the heart, you can learn it by following the people in the village to the field. And Li Tianyang and Wu Jie's father even held their ears at home, saying that they had water in their heads, and they didn't learn anything, but went back to learn to farm.

But who knows, if you don't even know how to plant the earth, then what qualifications do you have to learn and study the knowledge of biology? If it weren't for these years of farming and learning, how would Li Tianyang and them be able to let these foreign crops thrive in a foreign country, so that everyone can understand so much about the habits of sweet potatoes and corn. There is no way, Li Tianyang also wants to have special personnel to study these things, but Chinese Confucianism is the only one, and other disciplines are just some sideways and strange tricks in the eyes of readers, and it is difficult to get into the hall of elegance at all, so in today's world, basically no one is willing to work hard to study these things.

Li Tianyang can only train the partners around him to learn these knowledge from an early age, and select people who are interested in these things and have talents.

The teenagers did not have any doubts about Li Tianyang's decision. Since Li Tianyang established the hatchery and set up the breeding farm for the first time, it has opened everyone's eyes. It turns out that the world is so wonderful, as long as the temperature is enough, even without the help of the hens, those chicks can hatch. Later, Li Tianyang fed the chicks with different feeds, and the chicks raised with earthworm mixture feed grew much faster than the free-range chicks. When the chicks raised on earthworm feed have already begun to lay eggs, those free-range chicks have not even grown all the hair on their bodies.

Over the years, we have planted acres of crops hand in hand and watched them grow in different conditions under various conditions. This kind of experiment makes everyone deeply understand what Li Tianyang said, the magic of nature, and also believe in what Li Tianyang said, through cultivation, crops that can grow more food can be cultivated.

Because of these experiments, Li Tianyang found several teenagers who were interested and talented in farming and improving biological varieties from among these teenagers. Without everyone paying attention, Li Tianyang has begun to secretly cultivate these few talents who are priceless in Li Tianyang's eyes. Although I don't know the future, whether they can bring surprises and results to everyone. But if you don't accumulate steps, how can you reach thousands of miles, and talents are supposed to be cultivated and accumulated slowly. If you really want to be as written in the novel, just find someone at random, how powerful you can be, then it's not in ancient times, I'm afraid it's really in the future!

In addition to biology, Li Tianyang also cultivated several clever and talented teenagers, specializing in some experiments that Li Tianyang still remembers about knowledge, such as cement, soap and the like. Although up to now, everyone has not come up with a single result, but Li Tianyang believes that one day, there will be a surprise waiting for him.

"Today, there is nothing else but to fertilize the sweet potatoes that have just been planted in the field. As for how to fertilize, you don't need me to teach you by hand. "Today is a cloudy day, Wu Daoli doesn't have to wear a cloak on his head like he does on weekdays. He is very satisfied with his current job: he comes every five days to teach everyone what they should do at the moment, and he doesn't have to do it himself, and at the end of the month, he can get half a tael of silver to subsidize his family, and he doesn't delay his family's farm work.

"Yes, sir." Hearing about today's task, everyone split up. If you should pick manure, go pick manure; It's time to hoe, hoe, everything is so orderly.

The sweet potato seedlings in the field were just planted some time ago, and they were still a little listless when they went up, but between the stems and leaves, a few new shoots were extracted. The planting method of this batch of sweet potato seedlings is really one of Li Tianyang's few research results, although it is really necessary to study it deeply, in fact, it is Li Tianyang who plagiarized the planting method of later generations. But who said that no one has invented this method yet, just let Li Tianyang guide everyone, research out this technology, cheer everyone up, cheer everyone up.

Potato seedlings are separated from a complete stem and leaf, a stem and leaf more than one meter long can separate four or five six or seven inches long potato seedlings, according to their growth trend, the bottom end is buried in the soil two or three inches deep, after a period of time, it can take root again, grow vigorous stems and leaves. However, in this way, it will affect the ripening time of sweet potatoes, and it will basically delay the appearance of about a month.

However, compared with the previous method of planting sweet potatoes, it saves a lot of sweet potatoes, and the temperature of Qiongzhou Island is above 20 degrees all year round, which can basically ensure that the sweet potato stems and leaves in the land can be cultivated into the land as plants in addition to feeding livestock, so as to avoid the trouble of re-cultivation. In this way, it is not said that the method is better, but now everyone is not short of food, so they grow sweet potatoes in this way.

"Then, company commander!" Not far away, Gan Dabiao finished his work, dug out a few sweet potatoes from the ground next to him, and threw them directly.

"You're a glutton!" Li Tianyang smiled and scolded as he picked up the sweet potato from the ground, handed one to Changsheng and Decai behind him, and picked one up himself, cleaned up the mud and sand between the appearances, and bit it down. The sweet juice spread between his mouth, so that Li Tianyang, who had long been thirsty, couldn't help but suck a few more times, although there was still a hint of earthy smell, but it was difficult to hide the sweetness.

While doing the work, I enjoy the sweet potatoes I grow, and this taste is only so comfortable.
