Chapter 832： 832, soilless cultivation

During this period of time, not only Qin Mingsheng's experimental project, but also Mu Yiren's experimental project was in full swing.

The reason why she did soilless cultivation was also because Boss Qin talked to the couple about the cancellation of the centimeter system, especially when they talked about the treatment of their Linhai Village in the whole country, what would happen to the production teams in other places and so on. .

It was because of this that she suddenly had this idea.

Although she is doing research on microbial elements and does not involve much in agricultural biotechnology, she still understands the basic principles. After all, in a professional field, many knowledge points are the same.

Because she had no practical experience, she had to spend more time in the laboratory to organize and try things out. It took her more than ten days to finally figure it out.

"Soilless cultivation means very simple, that is, vegetables can be grown without soil."

Mu Yiren smiled and answered her third brother's question.

"Really? This kind of vegetables is grown in the fields and crops. If there is no land, how can these vegetables grow?"

Although Qin Mingsheng had a general understanding from the name just now, but now that he heard his daughter-in-law's answer with his own ears, he couldn't help being a little surprised.

The main reason is that he grew up in the countryside since he was a child, and has also done a lot of farm work. It can even be said that in the minds of everyone in the village, this vegetable is grown in the ground.

This is already a deeply ingrained perception!

If you tell everyone that you can grow vegetables without soil, you will probably be ridiculed and ignorant, and you are talking nonsense.

"Soil is just a medium, not the only necessary condition for the growth of vegetables. As long as vegetables are kept with sufficient water and nutrients, they can still grow well without the soil. Who stipulates that vegetables must grow in the soil? ?"

Mu Yiren explained roughly, and then laughed and joked.

"..." Qin Mingsheng was really choked up by his daughter-in-law's rhetorical question, and for a while, even he himself had doubts.

Yes, they know how to farm. In fact, they are taught by their ancestors from generation to generation. The descendants of future generations have never questioned, and they have learned it hand by hand.

To put it bluntly, they just followed the steps of their predecessors, and they never thought whether this way of planting is the only way?

No one has even studied other planting methods, and it has been learned from generation to generation.

But even so, no one can say with 100% certainty that there is no other way of planting, it's just that they are stupid and keep spinning in a circle.

"Daughter-in-law, how is your experiment? Have the vegetables been grown? What kind of? Come on, let's go home now, I want to go and see."

After thinking about it, Qin Mingsheng suddenly couldn't wait to see the vegetables grown in soilless cultivation. Are they the same as those grown in the ground?

In short, he is now very interested in vegetables grown without soil, just like he is doing experiments on his own and is inexplicably excited.

Seeing the third brother who hurriedly walked to the villa with his son in his arms, and the Muyiren who were a few steps behind, they were a little dumbfounded. Her third brother was full of curiosity.

So, the family of four stopped walking and hurried back home.

Putting the two children in the children's play area in the living room, Mu Yiren took her third brother into her laboratory.

Qin Mingsheng saw at a glance that there was a wooden shelf with three rows of brackets in the house, and five glass jars were placed in each row, and each glass jar was actually planted with various kinds of vegetables.

The most amazing thing is that there is no soil in the glass jar, only half a jar of water, but these vegetables are growing well, the leaves are very lush and green, and they don't look like they are smashed because they are separated from the land. .

Such vegetables are no worse than those grown in vegetable fields. On the contrary, the branches and leaves are more lush.

Qin Mingsheng walked to the wooden shelf and couldn't help but reached out and touched the leaves of the vegetables, in order to confirm whether what he saw was real.

"It's amazing! Daughter-in-law, how did these vegetables grow?"

Qin Mingsheng has always been fond of learning. If he doesn't understand something, he will ask directly until he understands it.

Before, his daughter-in-law had brought her family to grow vegetables at home. Although it was also separated from the land, it was still in the cold season of winter, but the vegetables at that time were still grown from soil.

Installed in a wooden frame, it can be regarded as a small land.

But now there is no soil at all, only a little water, he really can't imagine how these vegetables grow.

Seeing the curious appearance of the third brother, Mu Yiren smiled and explained the concept of soilless cultivation to him.

Soilless cultivation refers to a cultivation method in which a substrate is used without natural soil, or a substrate is only used when raising seedlings, and nutrient solution is used for irrigation after planting.

Soilless culture can artificially create a good rhizosphere environment to replace the soil environment, effectively prevent the physiological obstacles caused by soil continuous cropping diseases and soil salt accumulation, and fully meet the needs of crops for environmental conditions such as mineral nutrition, water, and gas. The basic materials can be recycled, so it has the characteristics of water saving, fertilizer saving, labor saving, high yield and high quality.

The artificially prepared culture solution used in soilless culture is needed to supply plant mineral nutrients. In order to make the plant stand upright, quartz sand, vermiculite, peat, sawdust, plastic, etc. can be used as supporting media to maintain the ventilation of the root system. .

"Also, according to many years of research in later generations, crops such as soybeans, peas, wheat, rice, potatoes, tomatoes, cucumbers, etc., the yield of soilless cultivation is higher than that of soil cultivation. This time I tried fifteen kinds of common crops. Vegetables, sure enough, the development of seedlings is very good, and I believe that the output will definitely increase by then."

After listening to the story of his daughter-in-law, Qin Mingsheng felt a lot of fluctuations in his heart. He felt that the world was really magical. Every change might produce countless results, but he himself knew very little.

Maybe in the eyes of others, he is a scholar with a smart mind and a lot of knowledge, but he feels that in the face of changes in nature and in front of all scientific phenomena, he is like an ignorant child.

Sure enough, there is no limit to learning. The knowledge he knows now is not enough. He really needs to live until he is old and learn when he is old!

"Is this the nutrient solution?"

Suddenly, Qin Mingsheng's eyes were attracted by a small wooden shelf next to the wooden shelf. Seven or eight glass test tubes were inserted on the small wooden shelf, and the test tubes were filled with liquids of three different colors.

This made him think of the nutrient solution mentioned by his daughter-in-law just now.
