Most of them had never planted corn before. Most of them only learned about other crops later because they were forced by Li Yi to do so.
"What should we plant when corn is harvested?" Wei Zhigu squatted down to look at the corn seedlings.
"Wheat." Li Yi stretched out two fingers.
"Is it during the normal corn planting season?" Yao Chong asked.
"After the winter wheat is harvested," Li Yi replied.
"After the wheat is harvested, we plant corn. After the corn is harvested, we plant wheat? How do we deal with the wheat stubble? "Bi Goo found that they belonged to the same circle.
"Don't care. Just plant corn. If we plant it lightly, the wheat stubble will naturally rot in the ground. After the corn is harvested, it's more troublesome. We have to plough before we can plant wheat. "
Li Yi considered the cost of labor. He didn't want the people to destroy the wheat stubble after harvesting.
Without equipment, people or animals would have to plow and bury the wheat, and the time cost was too high. It wasn't worth it to harvest more.
If they had the time to plow, it was better to rest and recuperate. They had just finished harvesting wheat, so they were already very tired.
Lu Huaishen couldn't imagine how the seedlings in front of him would grow corn. He asked, "Where does corn grow from?"
"It's similar to sorghum. I'll show you a picture later. The corn now is cultivated by the indigenous people of other places. We have to cultivate it ourselves. "
Li Yi grabbed a handful of soil and checked the humidity.
"How much corn did you plant in one mu of land?" Song Jing didn't want to count and asked directly.
"Three thousand five hundred stalks for seed. If you're harvesting silage and don't pursue the corn yield, you can plant four thousand stalks per mu.
If you want to eat boiled corn, you can plant two thousand five hundred to two thousand eight hundred stalks per mu.
The remaining corn can also be eaten in advance. It's not worth it to use it for silage. "
Li Yi calculated the ratio. In the Tang dynasty, one mu of land wasn't 666 square meters, but about 540 square meters.
"How much is the yield per mu?" Li Longji was concerned about the yield.
Li Yi shook his head slightly. "I don't know. In any case, it's higher than any crop in the Tang dynasty. There are also potatoes and sweet potatoes. The yield per mu is pretty good."
Li Yi really didn't know. He had just brought it back and weighed it after planting it.
After all, it couldn't compare to the corn yield of his time. Without pesticides, pests and diseases would reduce the yield of corn.
There were only mineral fertilizers for fertilizers. Fortunately, there was manure for farmers. When the river was cleaned, silt could be dug out.
Everyone chose to believe Li Yi when he said that the yield was higher than other crops, and then turned to the potato field.
Potatoes also sprouted seedlings, neatly arranged in the ground, with furrows for watering.
"Potatoes are a good staple food. Everyone has eaten potatoes before.
Under normal circumstances, the yield is higher than that of corn, but the disadvantage is that it is not easy to preserve.
If they didn't eat the harvest of the current season, they would all become seeds next year. At most, they could only be kept until the beginning of spring.
Unless it's made into potato powder and can be stored for a long time, the production process will delay manpower. "
Li Yi pointed out the shortcomings of potatoes. Otherwise, how good would it be if everyone grew potatoes?
Yao Chong didn't care. "After we harvest the potatoes, we'll eat them until spring to save on other staple foods."
"There's no need for that in the south. We can grow other crops in the south during the winter.
The area around Dongting Lake, Guangzhou, Lu Zhou, and the other regions, as well as the eastern path of Jiangnan, could become the main food production areas of the Tang dynasty.
The Guanzhong area is also quite important. The grasslands further north are suitable for growing potatoes. "
Li Yi knew how important potatoes would be in the future. In the cold places in the north, potatoes, cabbages, radishes, carrots, and onions were the main vegetables in winter.
In fact, the areas north of the Yangtze River such as Henan Province were cold in winter.
They passed through a large field of potato seedlings and came to the front of the sweet potato seedlings. The two large fields were separated in the middle.
Li Rizhi didn't understand. "They're both furrows and furrows. It's convenient for watering when they're connected."
"Sweet potatoes can't be watered when they're planted. After that, unless it's too dry, they can't be watered, especially the furrows."
Li Yi explained patiently. The others really didn't understand.
The land used for breeding was fertile enough.
After looking at the sweet potatoes, they came to the tomato field.
Everyone looked and found that it was different. The leaves of the plants were the same. Some of them had a shelf and a small green ball on it.
In addition, there were more that didn't have a shelf. The seedlings were short.
Li Yi didn't need anyone to ask. He said himself, "On the way back, we were in a hurry to eat, so a small number of seedlings were planted in advance. The rest were planted when the weather was warm.
The seedlings grew quickly, and they could be eaten in another 20 days. The selected seedlings were kept.
Like cucumbers, not all cucumbers could be turned into seeds.
In winter, the seedlings in the greenhouse were changed to hanging vines. Fertilizer was added. It was a type of intensive planting and saved space. "
"I know. Last year, all the vegetables in the Li Family Zhuangzi that should have a shelf were hung on ropes with clamps. The yield was high."
Bi Goo knew that not only the Li Family Zhuangzi, but also the Liuli Village, Xiaolan Village, Imperial Village, and the greenhouse field behind the Imperial City all used the same technology.
The more fruits they produced, the easier it was to manage, and it was convenient to pick them.
The difficulty was that the shelf of the greenhouse had to be strong. Otherwise, it wouldn't be able to hold.
In addition, the silk greenhouse had poor light transmission and was too dense. Unless there was an additional light source, it wouldn't grow big.
The people couldn't learn it, so it was useless to tell them.
It was already good enough that they grew their own greenhouses and increased their income.
In the past winter, they couldn't find a way to make more money. The people of Chang 'an couldn't eat cucumbers. Only the royal family could eat some vegetables that were out of season.
Next to the hot springs or building a heating system, they never thought that there would be greenhouses.
"There's no rush to promote this non-staple food … right?" Su Yi said confidently, but he suddenly hesitated. Let's add one.
"The people can eat fruits, so naturally, they don't lack tomatoes. The yield of tomatoes is higher than fruits. They can be eaten as both fruits and vegetables.
The harvest period is long, and they grow as they are picked. Those who have a yard can plant tomatoes like cucumbers.
When the children can't eat fruits, they can eat tomatoes to replenish some nutrients.
Make soup with tomatoes. It's sweet and sour. In summer, put it in the well water. The taste is no worse than eating watermelon. "
Li Yi swallowed his saliva as he spoke. He was hungry.
He didn't like scrambled eggs with tomatoes, but he liked tomato and egg soup. Stewed beef brisket with tomatoes was also good.
However, he knew that many people liked scrambled eggs with tomatoes. This dish was indeed good.
They walked past the tomato planting area and turned to the various chili plants.
"We have to enrich the people's food basket. In winter, there's less to eat because of the weather. When the weather is warm, try to let the people eat more.
Especially when the children are growing and have a yard, they can plant strawberries. There are many varieties of strawberries.
The ones I brought back are bigger and better than the ones we have in the forest. They can be crossbred.
In addition, there are cherries, grapes, peaches, plums, and apricots. The children can eat more nutrients and it's good for their growth. "
Li Yi didn't focus on the staple food. Vegetables and fruits were equally important.
Speaking of this, Lu Huaishen said, "Let's not talk about the distant things. Children are used to eating eggs. They remember things quickly.
My people have children at home. I don't give them much money now. They earn it themselves.
The children eat two boiled eggs in the morning. In winter, they cook them and cover them with blankets. Their health is good. "
