Collect crowd into immortals

Chapter 84
"Since it's a matter of soil fertility, let's continue to select based on size! As for individual selection, let's talk about it later!"

"Well, that's okay! At least we should find out the limits of this method first!"

Regarding the proposal of the second brother Qingxuan, among the five siblings, even Chen Qingzhu, who valued Fangu the most, did not raise any objections.

After all, individual breeding is much more troublesome than the current large-scale breeding.

After reaching a consensus, several people were ready to take action.

But at this moment, the sixth sister Qingyu suddenly stopped them, "Wait, wait first! Third sister, how do we ensure that the soil fertility is the same? If it is not the same, does it mean that the yield is also different? Same? And does that also affect the size of the wheat kernels?"

Upon hearing her reminder, Qingzhu and others who were about to take action immediately stopped what they were doing.

"This...this is indeed a problem!"

As they said that, they also took out the wheat seeds just now, that is, the original ninth batch and the ninth batch with enough fertilizer, and made a detailed comparison.It turned out that in the case of sufficient fertilizer, the particle size limit is indeed a circle larger than when there is a lack of fertilizer.

Under such circumstances, it is difficult for them to judge whether the largest particles they selected before are what they want?
After all, it is very possible that the mediocre wheat seeds before will suddenly make a leap and grow into the best batch when they are fertile enough.

More importantly, it is difficult for them to determine what the truth is.

Especially, when a wheat seed can only be planted once.

Even if they repeated the experiment, it seems that they are not very accurate.

Therefore, the five discussed it for a long time, but they still couldn't come up with any good solution.

Unless they can find some method or magical power to replicate the wheat seeds exactly, and there must be some way to measure soil fertility.

Only in this way can the problems raised by the sixth sister Qingyu be completely solved.

As for now...

"Let's not worry about so much for now. Let's try to find out where the maximum yield of wheat is!

As for soil fertility?Just add as much as you can!
By the way, as for fertilizer, we can increase it according to the output of the first batch. After all, the more produced, the more consumed! "

"Too!"

In this regard, Qingzhu and the others had no other choice but to agree.

Later, they experimented several more times and roughly worked out a relationship between fertilizer and yield.

Of course, in order to be more rigorous, they opened up another piece of land of the same size.On this piece of land, there will always be [-]% more fertilizer than the first piece.

In this case, if the yields of the two plots of land are almost the same, it means that the limit has indeed been reached.

If the second block is too much, then continue to add fertilizer until the limit.

In this way, they soon measured the limit yield of the previous tenth batch, and half an acre of land produced a full 460 jin.

460 eight catties, which is fifteen catties more than the limit of the ninth batch.

This shows that even if the number of grains per panicle of the tenth batch is a little less than that of the ninth batch, it does not affect the fact that its yield is higher!

In other words, the tenth batch of wheat seeds was even better than the ninth batch.

At least, that is true if there is enough fertilizer!
Similarly, this phenomenon also rekindled the confidence of the five brothers and sisters.Since large-scale selective breeding is still useful, let's do it to the limit first!
After making up their minds, a few people made persistent efforts!

Planting, ripening, harvesting, breeding, soil plowing, fertilizing, and then planting...

Same as the previous steps, the only difference is that there is an extra action of fertilizing.

But this is also simple, just go to the field to ripen a few trees, or ripen a batch of wheat, and then use the [Grass and Tree Art] to turn them into fly ash.

And this fly ash is actually the fertilizer applied.

As for the weight of fertilizer, just calculate it according to the formula summarized before.

If not enough, add as appropriate.

In this way, with the rounds of breeding, the wheat grains are getting bigger and bigger, and the yield is breaking through the limit time and time again.

The tenth round, 470 five catties!

No.15 rounds, 490 catties!

No. 20 rounds, five hundred and one catties!
No.30, 520 pounds!

Wheel, 550 catties!

No.80 rounds, 570 catties!

……

Soon, at round 185, this data reached the limit, reaching 620 two kilograms.

Half an acre of land, 620 two pounds!That’s almost [-] kilograms per mu!

Looking at the latest round of data, Chen Qingzhu was shocked speechless.

One thousand three hundred kilograms, this was a figure that she could hardly imagine.

You must know that before this, her family's field could produce [-] catties, it was a fluke and God blessed.

Now that the number has more than doubled, how could this not shock her.

To be honest, if she hadn't seen it with her own eyes, or even cultivated it with her own hands, Chen Qingzhu would never have believed that the yield from one acre of land could reach such a high level!

Thirteen hundred catties, I'm afraid I've eaten an elixir!
Although such a high yield cannot be achieved without the support of spells and fertilizers.

But you must know that even if the first batch of wheat seeds also had these two blessings, its maximum yield was only [-] catties.

Now, through their hard work, the output has doubled.

How could this prevent the five brothers and sisters from being shocked inexplicably, even while being shocked, they were also filled with pride in their hearts!
This is all their fault!

Although this wheat is only supplied to mortals and is of little use to those who cultivate immortality, it is enough to make several people laugh happily three times.

for a long time.

After calming down, Sixth Sister Qingyu started her complaints as usual.

"It's just a waste of fertilizer!"

Isn't that right? In the tenth batch, half an acre of land only needed about 150 catties of fly ash, but now, it has almost doubled, and more than [-] catties are needed to meet the demand for the maximum output.

That doesn't sound like much.

But you must know that the fly ash (that is, fertilizer) that a big tree surrounded by its arms can produce is only a little over a thousand catties.

It would take at least a hundred years for ordinary trees to grow to such a large size.

In a hundred years, if the monks in the Qi refining period hadn't maintained their health well, they would have entered reincarnation.

But the big tree that has grown for such a long time is actually just enough to meet the fertilizer needs of less than five acres of land.

It can even only be managed for one season!
It has to be said that the price is really high!
"But it's necessary! You can't just get out and not get in! Our soil is not the legendary soil. As long as it has aura, it can grow infinitely!"

Qingzhu said so!
If you want to have output, you must have input!
You can't expect that the land under your feet can be like the legendary cornucopia, it can always be created out of nothing!

What's more, even if it is a spiritual field, spiritual fertilizer must be applied to ensure the yield, and the mortal land in front of them is no exception!
After figuring it out, the five brothers and sisters no longer struggled with the matter.

It’s just fertilizer, but for them, it’s simply too much!

With a set of [Spring Breeze Transforming Rain Technique] and the [Grass and Tree Technique], they could collect hundreds or even thousands of kilograms in just a quarter of an hour.

If you put in a little effort and make a thousand pounds a day, it will be easy!
But if you want to supply the planting needs of mortals, then...

The five brothers and sisters shook their heads together like a rattle.

Just their Lianhu Island alone has hundreds of thousands of acres of land.Relying on them alone would exhaust them to death!
Of course they don’t want to do it!
So when it was learned that the improved new varieties needed enough fertilizer to be effective, even Chen Qingzhu, the third child from a mortal family, didn't think about promoting it immediately.

At least at least, they have to get the fertilizer problem done first!
Otherwise, after a few rounds like this, [-]% of the land will be scrapped!

"For fertilizer, I use farmyard manure at home, which is fermented from all kinds of manure, weeds and branches. I don't know how effective it is?"

As she spoke, Chen Qingzhu seemed to be back in the summer when the smell was sour and flies were flying everywhere. As she thought about it, she quickly shook her head, "Forget it, let's talk about this later!"

"Okay! What about now?"

Seeing that the third sister had temporarily given up the fertilizer, the sixth sister Qingyu opened her eyes wide and asked curiously.

You know, up to now, they have reached the limit in terms of large-scale breeding.

At this time, the size of a single grain has more than doubled from the beginning, and the number of grains per ear has also dropped to about 20.

If they continued the experiment, they found that the number of grains per panicle may decrease further, but the size of the grains has basically reached the upper limit and will not change any more.

In other words, the current output has reached the limit of what can be achieved at this stage.

Similarly, the method of large-scale selective breeding has reached its upper limit, and it is time to eliminate it.

At this time, if you want to continue to make breakthroughs, you can only choose the "single plant breeding" mentioned before.

But "single plant selection" is too time-consuming and energy-intensive, so Qingyu wants to ask Third Sister if she wants to continue.

If we continue, how should we allocate our time?

Do you devote all your rest time to it, or half and half?
In this regard, the youngest Chen Qingzhu didn't know what to do.

She didn't know if she should continue to waste the time of the other four siblings.

After all, the result of this kind of thinking is probably based on years.

And just when she was thinking a lot in her mind, she saw her second brother, who usually pays a lot of attention, muttered again: "Don't worry, the large-scale breeding should not have reached the limit!"

"not yet?"

Qingxuan's statement confused the four younger brothers and sisters.

Isn't it already here? Why did their second brother say he didn't arrive?

Is it my second brother who is talking nonsense?
Or did he have some new ideas?
Out of curiosity, they saw their second elder brother cough lightly, looked at the withered and yellowed wheat stalks for a while, and then said in a deep voice: "Have you noticed a problem, we just applied pollen to her mother plant before?" But in fact, in nature, the pollen of wheat should be blown by the wind. Isn't it?"

"Hey! It seems like that too!"

Regarding this novel statement, the four people in Qingzhu were surprised, and then a light flashed in their eyes.

According to their previous observations, this is indeed the case.

Although, according to the previous division method, wheat is a self-pollinating plant.However, since the stamens and pistils of wheat do not close during pollination, cross-pollination usually occurs in wheat.

Of course, the chance of this happening is very low, only about one to three percent.

But it does exist, so it cannot be completely ignored.

But what's the use of this?
Will this increase production?
For a moment, Qingzhu and others' eyes were full of excitement, sometimes in disbelief, sometimes curious, and sometimes eager to try.

As for this, Chen Qingxuan still said the same thing: "Whether it works or not, let's try it and then we'll know!"

"Right!"

The four people who were completely accustomed to this didn't say much and started taking action directly!

It’s still the same as before: fertilizing, planting, ripening, pollination, harvesting, and breeding.

It's just that in this stage of pollination, they directly used the [Object Control Technique] to isolate all the pollen, completely abandoning self-pollination.

Moreover, they also used [Imperial Object Art] to spread the pollen produced by each plant evenly on the rest of the ears of wheat.

Rain and dew all soaked!

After this batch of wheat matured, they suddenly discovered that the yield of this batch of wheat was still the same as that of 185 rounds, which was also 620 jin.

This is not a problem, the problem is the next batch.

When they planted this batch of wheat, they found that with sufficient fertilizer, the wheat yield actually plummeted, dropping by more than 50 kilograms.

Just when several people were disappointed, Chen Qingshan, who was in charge of the breeding, first discovered the problem.

Because he suddenly discovered that the particle size distribution of this batch of wheat actually returned to the original, with some large and some small.

(The 185 rounds of wheat seeds have not been selected. Because after multiple rounds of breeding, the wheat seeds of this batch have been completely stable, and the wheat grains produced are basically the same size, which can be regarded as the same wheat species. As a new benchmark Just fine)
There seems to be nothing surprising about this, but what shocked Chen Qingshan was that there were dozens of wheat grains that were two or three times larger than the 185 rounds.

Bigger than 185 wheels!

That is to say, the single grain size of wheat has a new limit.

And this seems to be the goal they have tried more than 100 times before!

Seeing this surprising result, the five brothers and sisters immediately regrouped and continued the experiment.

Since there were only dozens of seeds, they didn't do anything big this time. They just chose a place about a foot square and started a new round of experiments.

Fertilizing, planting, ripening, self-pollination, harvesting, and breeding.

During the final selection process, they were full of confidence and expectations, expecting to break through new limits. Unfortunately, the results were not as magical as they imagined: the theoretical yield per mu still did not break through the limit.

However, they also discovered an unexpected fact: almost half of the wheat remained the same size as the seeds.

As for the remaining half, they are much smaller and vary in size.It is also because of their existence that production is reduced.

Seeing such a situation, the disappointment of several people was swept away, and their confidence was rekindled.They replanted the seeds that had maintained the size, and after self-pollinating, they got another batch of wheat of varying size.

Select the ones that remain the same size and continue planting.

In this way, after four or five reincarnations, they obtained another batch of wheat seeds that could be stably inherited, and the size was larger than before the new method, and the yield per mu was even higher.

The theoretical yield per mu has even reached [-] kilograms.

The real thirteen hundred catties!

After getting this result, the five brothers and sisters were immediately overjoyed.

The production has exceeded the upper limit, which shows that the method they have just adopted is completely effective.The new method can indeed push the limits of output.

Since it works, they will naturally make persistent efforts.

A new round of experiments continued.

It took almost another month. They tested the wheat seeds produced in the first round of the new method one by one (the first batch of hybrid seeds). After thousands of rounds of breeding, they selected a version with the largest yield .

At this time, the yield per mu has reached a new limit, reaching [-] catties!

With the gratifying results, the five brothers and sisters are not giving up. They want to continue to explore the limits of this new method.

So on the basis of [-] catties per mu, a new round of pollen hybridization work continued.

……

And while they were busy breeding, there were new movements on Ziyun Island.
