"It's not a bumper harvest, it can only be said that there are enough plants for one person to eat." Regarding the envy expressed by Li Wensheng, Chen Xin only shook his head slightly reservedly.

Although the yield of rice in the field is good, it is really not a good harvest, especially since he grows upland rice, which is only 60-70% of rice.

Hearing Chen Xin's explanation, Li Wensheng could only nod his head in understanding, and agreed with Chen Xin's opinion, but he also put forward an idea: "Writer, can you change the paddy field here?" If you grow rice, the yield of paddy fields will be higher, right? ”

"Paddy fields? Do you have paddy fields underground? Chen Xin frowned, feeling that this was a bit unrealistic.

However, Li Wensheng explained: "Of course, the traditional irrigated paddy fields in the underground are not good, but what if the writer is hydroponics? It should be possible to grow rice on hydroponic trays and with water. ”

Li Wensheng's suggestion gave Chen Xin a lot of inspiration, and he hurriedly asked: "Rice itself is an aquatic crop, isn't it planted directly in water?" How can there still be a water planting method? ”

"Although rice is planted directly in water, there are still requirements, and the water should not be too much, otherwise it will be waterlogged." Li Wensheng has been planting the land in a serious way, and he has some understanding of this nature: "Moreover, only the rhizome part of the rice is soaked in water, and if the leaves are also soaked in water, it is bound to get sick, so the water for planting rice should not be too much." As for the water planting method, the rice is fixed on the water surface with a planting tray, and the root system is still soaked in the water, but the other parts are located on the water surface. ”

Listening to Li Wensheng's explanation, Chen Xin suddenly understood, he nodded and said: "I understand when I hear you say this, but this planting method is simple to say, but it should be difficult to operate in practice, right?" ”

"It's not easy, I've seen people do it before, it's not easy, but it's done on the lake, you are planting greenhouse, there is still a difference." Li Wensheng admits that there are indeed technical difficulties in planting rice in this way, but it does not mean that it is completely impossible.

Chen Xin nodded understandingly, didn't say anything more, and Li Wensheng also saw the opportunity to say goodbye and leave.

After sending Li Wensheng away, Chen Xin returned to the shelter, still thinking about the water planting method mentioned by Li Wensheng.

If you can grow rice in hydroponics? Of course, Chen Xin can calculate how much the output has increased? It's a tempting enough idea.

The yield per mu of upland rice is normally about eight or nine hundred catties per season, but the yield of rice is much more? Even if you don't count the super rice in Yanguo that is running wildly with tons of yield per mu? Even if it is ordinary rice, the yield per mu can reach 1,000 catties to 1,200 catties? Some high-yielding varieties can even reach about 1,500 catties.

In addition, rice in most areas of Yanguo can be doubled or triple cropped a year, so farmers who farm the land only need to be a little more diligent? Growing scientifically? There is no problem in growing a ton or two of grain from the ground in a year.

If you change to upland rice, even if you use a greenhouse like Chen Xin, you can only get more than one ton of yield by planting three crops a year.

Although high-yielding rice is very dependent on the cross-breeding of rice seeds and the use of fertilizers, even so? Can you grow some food? It is also very tempting for Chen Xin.

Maybe the next time you upgrade your planting greenhouse, you can make a modification to the current planting model?

Chen Xin seriously thought about the feasibility of this idea, and had a system in hand, even if he really changed the land in front of him into a paddy field, he was not worried that his idea would not be realized.

————————————————————

In addition to the ten fish sent by Li Wensheng? Li Yulong's side also quickly sent the seeds promised to Chen Xin.

Peppers, eggplant, spinach, coriander, tomatoes, radish, lettuce, chrysanthemum, carob, lentils, red amaranth, water spinach......

Chen Xin counted the packets of seeds sent by Li Yulong, and a rather happy smile appeared on his face.

The seed packets he bought originally included these common crops? According to Chen Xin's original idea, he should be in his own planting greenhouse? Half of the land grows food and a quarter of it grows vegetables? A quarter of the land is also used to grow fruits.

So? Even if the access to food from the outside world is cut off? He can still eat and drink in the underground shelter.

But people are not as good as heaven, who would have thought that he bought seeds and the courier did not deliver them to him?

Chen Xin thought that after the end of the world, he could only eat cabbage, lettuce and carrots.

But now Chen Xin no longer has this kind of trouble, after having this batch of seeds sent by Li Yulong, Chen Xin can live a life of eating and planting whatever he wants, greatly enriching his recipes, so as not to make his intermediate chef certificate become a piece of waste paper.

And there is something that makes Chen Xin especially happy and excited, that is, the seeds of more than a dozen fruits.

There are mangoes, watermelons, strawberries, dates, cantaloupe, kiwi, oranges, lychees...... Although some of these varieties are no longer easy to grow, Chen Xin can grow strawberries, watermelons, grapes, etc. in his own planting greenhouse.

God, he really hasn't eaten fruit for more than half a year.

This made him can't help but want to plant something first when he got the seeds, so as to comfort his long-awaited stomach.

Fortunately, Chen Xin restrained this impulse.

His planting greenhouse is now used to grow vegetables in hydroponic trays, and before this batch of vegetables is harvested, it is impossible for him to say that the vegetables he is growing are pulled out in advance and replaced with fruits.

Although the field is now vacant, Chen Xin decided to continue to grow rice instead of moving the field out to grow fruits.

Of course, after this batch of carrots is harvested, Chen Xin still plans to reduce a certain amount of carrot planting area and free up a small piece of land to grow strawberries or something to improve his diet.

In addition, Chen Xin must also consider what Li Yulong wants to get from him for so many benefits.

You must know that Li Yulong has come to Chen Xin several times, except for the fruit and vegetable machine, which is not a valuable thing, the two hams and this large number of seeds he sent are hard currencies that are very popular in the last days.

Chen Xin didn't feel that his relationship with Li Yulong was so good that he could give himself things like this without asking for anything in return, there was no good thing in this world that did not ask for anything in return, not before the end of the world, and even less after the end of the world.

Chen Xin only agreed to cooperate, and the cooperation has not yet begun, Li Yulong has invested so much in advance, what he wants will only be more.
