I make a popular science video and all the emperors learn from it!

【Soilless Cultivation Technology:】

[Soilless cultivation refers to the cultivation method of using water, peat, forest humus, vermiculite and other media as the substrate of the plant root system to fix the plant, and the plant root system can directly contact the nutrient solution. 】

[The composition of the nutrient solution in soilless culture is easy to control and can be adjusted at any time. 】

[In places where there is no soil with suitable light and temperature, such as deserts, beaches, and desert islands, as long as there is a certain amount of fresh water supply, it can be carried out.] 】

[Soilless culture is divided into hydroponics, aeroponics and substrate cultivation according to the different cultivation media. 】

[Hydroponics refers to the cultivation method in which the plant roots are in direct contact with the nutrient solution and do not use substrates. 】

[The earliest hydroponics is to immerse plant roots in nutrient solution to grow, this way will cause hypoxia, serious cause root death. 】

[After that, the hydroponic method of nutrient solution film method is often used, that is, a very thin layer of nutrient solution, which continuously circulates through the root system of crops, which not only ensures the continuous supply of crop water and nutrients, but also continuously supplies fresh oxygen to the roots. 】

[Technical Description:]

Soilless cultivation is a new technology for crop cultivation that has been developed in recent decades. 】

[Crops are not cultivated in soil, but in an aqueous solution (nutrient solution) dissolved in minerals, or in a certain cultivation medium, with a nutrient solution. 】

[As long as there is a "603" fixed cultivation equipment and certain management measures, crops can grow normally and obtain high yields. 】

[Because crops are cultivated by watering nutrient solution without using natural soil, it is called soilless culture.] 】

[The characteristics of soilless culture is to replace the soil environment with the artificially created crop root growth environment, which can not only meet the needs of crops for nutrients, water, air and other conditions, but also control and regulate these conditions to promote better growth of crops and obtain a better balance between vegetative growth and reproductive growth. 】

Therefore, soilless crops usually grow well, have high yields, and are of high quality. 】

[Soilless cultivation is free from the limitation of soil, which greatly expands the space for agricultural production, so that crops can be produced on barren land, and the development prospects are very extensive. 】

[Almost all plant factories adopt a soilless cultivation model. 】

【Advantages:】

[1. Water saving, fertilizer saving, high yield. 】

[The various nutrients required by crops in soilless cultivation are artificially formulated into nutrient solution and applied, with less water loss, balanced nutrients, high absorption efficiency, and scientific supply of nutrients according to the type of crop and the different growth stages of the same crop. 】

[Therefore, the crop grows and develops robustly, and the growth potential is strong, which can give full play to the potential for increasing yield. 】

[2. Clean and hygienic without pollution. 】

[Soil cultivation and application of organic fertilizer, fertilizer decomposition and fermentation, odor pollution environment, but also make many pests eggs breed, harm crops, and soilless culture is applied inorganic fertilizer, there are no these problems, and can avoid the pollution of heavy metals and other harmful substances in the polluted soil. 】

[3. Labor-saving, labor-saving, easy to manage. 】

[Soilless cultivation does not require cultivating, ploughing, hoeing and other operations, saving labor and labor. Watering and topdressing are solved at the same time, and are regularly and quantitatively supplied by the liquid supply system, which is convenient to manage, will not cause waste, and greatly reduces the labor intensity. 】

[4. Avoid continuous cropping obstacles. 】

[In the field planting management of vegetables, reasonable land rotation and avoiding repeated crops are one of the important measures to prevent the serious occurrence and spread of diseases. 】

[Soilless culture, especially the use of hydroponics, can fundamentally solve this problem.] 】

[5. Make full use of space without regional restrictions.] 】

[Soilless cultivation makes crops completely separated from the soil environment, not limited by soil quality and water conservancy conditions, and many deserts, wastelands or areas that are difficult to cultivate on the earth can be used by soilless cultivation methods. Getting rid of the constraints of land, soilless cultivation can also be free from space limitations, using the flat roofs of abandoned factories and buildings in the city to grow vegetables and flowers, all of which have virtually expanded the cultivation area. 】

[6. It is conducive to the realization of agricultural modernization. 】

[Soilless cultivation frees agricultural production from the constraints of the natural environment and can be produced according to human will, so it is a controlled agricultural production method. To a large extent, farming according to quantitative indicators is conducive to the realization of mechanization and automation, so as to gradually move towards an industrialized mode of production. 】

【Scope of application:】

Because soilless cultivation gets rid of the restrictions of soil cultivation, it has broad development prospects. 】

【Soilless culture has a wide range of applications, mainly used in the following aspects:】

【Plant factory hydroponic vegetables. 】

[(1) Used for vegetable cultivation: cultivating pollution-free green food, which is healthy and safe, and is highly valued by people. 】

[2) For floriculture]

[Whether it is cut flowers or potted flowers, it is suitable for soilless cultivation, and soilless flowers not only have large flower heads, but also bright colors. 】

[(3) Used for the cultivation of medicinal plants. 】

[Many medicinal plants are root plants, the growth environment of roots is very critical, soilless cultivation can provide a good growth environment for medicinal plants, so the planting effect is very obvious. 】

[4) Used for fruit tree cultivation. 】

【The rootstock seedlings of fruit trees cultivated by soilless culture grow fast and have a high survival rate; the fruit trees with fast rooting and high seedling rate are cultivated by cuttings. 】

[(5) Used for soilless seedlings. 】

[Soilless seedlings grow rapidly, the seedling age is short, the root system is well developed, strong and neat, and the seedling time is short and easy to survive after planting. It can also avoid soil-borne diseases and insect pests brought by soil seedlings, and is also convenient for scientific and standardized management. 】

[In addition, on the roof balcony of the city without land, soilless cultivation can be developed to grow vegetables and flowers to regulate life and beautify the environment, and in desert islands, beaches and sand, stone, and saline-alkali land that are not suitable for planting, soilless cultivation of vegetables can be developed in a large area to solve or alleviate the problem of food supply. 】

【......】

[Please see a short video of the practical application of soilless culture below.] 】

[Video source: XX vegetable breeding base. 】

The short video mainly shows the types and growth of vegetables in the breeding base.

Actually, it's like an advertisement.

But the ancients watched it with relish.

"Oh, I was cheap just now!

"This brother, just now Zhang heard with his own ears that you didn't say so, why did you suddenly change your words, did you want to laugh to death?"

"We can farm without soil! We have never seen such a bizarre thing in our lives. "

"Shocked, completely convinced. "

“..."

used to ridicule future generations of people who were full of food and smashed their jobs, which will directly change their words.

There was only envy and greed in the tone.

Especially the peasants who don't have land to plant, their eyes are straight!(If you read a violent novel, go to Feilu Novel Network!)

Qin Dynasty .........

All the people in the peasant family, like a thunderbolt, were stunned in place.

It's getting more and more wicked!

They can understand that people can fly, after all, there are many animals that can fly.

You can farm land, you don't need land, that's too bizarre.

Even thriller!

Most of them were speechless with their mouths open.

Many people even knelt down towards the light curtain and begged the light curtain to give them a little culture liquid.

Xianyang Palace.

Ying Zheng was confused for a while.

Then I almost shouted out and asked the guards to escort me!

Is this technology???

It's clearly a witchcraft!

Get out of the world![]

It's even a bit against the five elements...

The five elements restrain each other, and as a result, this light curtain tells him that he doesn't need soil!

"Evil arts! Such evil can be mastered by a person after the operation. Ying Zheng's teeth chattered slightly, he was a little frightened, and he didn't dare to think that future generations could make any outrageous moves!

Han dynasty.

Xiao He stumbled directly.

Since he assisted Liu Bang in winning the world, he has been helping to deal with logistics matters.

Naturally, there is no shortage of deals with grain and grass.

But he never thought about it, and even in his dreams, he didn't need land to grow plants and trees!?

Of course, the technology of soilless cultivation is powerful and can benefit the people of the world.

But in his opinion, the most powerful person is the person who came up with this technology!

Xiao He admired it so much that he threw himself to the ground.

"Okay, the descendants have surprised me again!" Liu Bang clapped his hands excitedly.

As for why clap your hands?

Of course, to break the surrounding, silent and eerie atmosphere.

As the emperor of a country, how can he be as frightened as the ministers!

"Yes, Your Majesty is very true. "

"We were all scared. "

“..."

The ministers were relieved from the shock one after another.

Ming dynasty.

Zhu Yuanzhang is not for the sake of taking care of his identity.

Just jumped up!

"This..."

"No, we don't understand. "

"You say that crops don't grow in the ground, they grow??"

Zhu Yuanzhang took off the hat on his head and scratched his hair vigorously.

He is also an authentic farmer, and he has traveled to many places, but he has never seen such a bizarre thing.

Even aquatic plants need to take root in the soil.

It shouldn't be like this!

Zhu Yuanzhang muttered: "Hey, we don't even need land for farming, so we don't need to seize the best land." "

Seeing that Lao Zhu was confused.

Zhu Biao on the side reminded: "Father, that is a technology that only exists in later generations, and farming in the Ming Dynasty still has to be planted in the soil." "

"Yes, yes, we're dizzy. "

Zhu Yuanzhang quickly pulled back his thoughts, responded to Zhu Biao, and then shouted around:

"Four good pieces of black land, you all give us a clear location!"

"It must all be in the hands of the Ming Dynasty. "

"Whether the people of our Ming Dynasty can eat three meals a day and eat enough at one meal depends on it. "。
