But after asking, Li Shimin regretted it.

If you ask this, you will seem that your knowledge is not as good as Zhao Chen!

I am the emperor, how can I...

Sure enough, Zhao Chen turned around and glanced at Lao Li's head, but also explained: "Watering too deep when heading, the rice stalks become soft and prone to fall backwards, and diseases such as striatum blight will spread and worsen."

"If the rice fields are short of water, it will cause the earing to be irregular and the number of empty grains will increase."

"No matter what the situation is, it will have a great impact on the subsequent harvest."

I see!

Li Shimin nodded in his heart.

I thought to myself that Zhao Chen knew so much, it was really amazing.

"In addition, when heading, it consumes a lot of nutrients. Remember to sprinkle fertilizer, and then spread fertilizer on the leaves."

"There is only ash in the wood." Zhao Chen continued.

If the phosphate ore cannot be found and phosphoric acid cannot be produced, otherwise it can be combined with wood ash to make potassium dihydrogen phosphate.

This is the most suitable fertilizer for rice heading.

The few people nodded, and behind them, Li Shimin, Empress Changsun and others listened with their ears.

The shock in my heart became stronger and stronger.

Zhao Chen even had a lot of things to say, and he was definitely not talking nonsense.

Li Shimin glanced at Empress Changsun, and his smile became brighter.

Empress Changsun smiled, but her eyes were always on Zhao Chen.

"The last thing to pay attention to is this kind of insect." Zhao Chen grabbed a small insect from the rice leaves.

The village chief is old and it takes a closer look to see clearly.

Li Shimin and others also surrounded him, but saw a small white worm being held in Zhao Chen's hand.

"This bug is common. It often appears in the rice fields in my home. As long as there are such bugs, the harvest will be very small?"

"But I don't know what can be prevented and treated." Li Shimin asked curiously.

He has a deep memory of this kind of bug.

Last year he planted some rice in the palace, which was originally growing very well.

Li Shimin thought the harvest would be good, but who knew that this white bug would appear soon after.

After that, the rice stalks fell down in pieces, and most of the rice ears were empty.

After working hard for several months, I was actually damaged by these insects.

Li Shimin was so angry.

Now, it seems that Zhao Chen has a way to deal with this kind of insect.

"The Book of Zhou" records that "Jiacao attacks it", "smoked grass to attack it", "smoked cymbals to attack it", "spraying it with ashes", "spraying it with ashes", "burning chrysanthemums with ashes" and so on...

…”

"Zhao Chen, these methods are too old, and these insects cannot be killed at all." Li Shimin shook his head.

I thought that Zhao Chen's method was just like this.

I couldn't help but feel a little disappointed.

"Have I said I should use this method?" Zhao Chen looked at Li Shimin strangely.

"Then do you still say?" Li Shimin said with some dissatisfaction.

"It's illegal for me to say it?" Zhao Chen said to Li Shimin with a smile.

Old Li was so angry that his teeth were about to break.

Can't this little bastard not let himself be embarrassed like this?

Li Shimin stared at Zhao Chen, waiting for Zhao Chen's method.

I thought if Zhao Chen's method was unreliable.

I have to make Zhao Chen look ugly, who has let this little bastard compete with me?

Empress Changsun shook her head and thought to herself that Zhao Chen had a strange temper, but she was quite looking forward to what Zhao Chen said.

"There are many domestic ducks in the village who have raised them all here."

"In addition, let the little kids not catch frogs, the pests will decrease soon." Zhao Chen said with a smile.

"It's that simple?" Li Shimin looked at Zhao Chen with a strange face.

How could Li Shimin be willing to believe that the pest that had annoyed him for several days was so relaxed in Zhao Chen's eyes.

Isn’t this slap him Li Shimin in the face?

"A small area is naturally not a big problem. If there are large-scale pests and diseases, it will not be possible for some ducks to solve it." Zhao Chen said lightly.

Li Shimin did not expect that Zhao Chen would be so calm, and his resentment in his valuable heart would calm down a lot.

I also lost my previous thoughts.

"Zhao Chen, it's really unbelievable that you didn't expect that you had such skills." Empress Changsun looked at Zhao Chen with a look of relief.

"That's right? Brother Zhao is a talented man from our villages. If he hadn't been poor, there would be no one in the court. Otherwise, the top scorer this year would have been our Brother Zhao." The village chief said with a smile.

There is no flattery in his expression, but rather an incomparable sincerity.

The other two villagers also looked equally serious.

Li Shimin did not expect it.

"Didn't the saint say that if you can win all the talents in the world, how could there be no way?" Li Shimin looked at the few people with some surprise.

"How could the noble man not know that although my Tang Dynasty is the world of saints, the most powerful one is the five surnames and seven hopes."

"Which official in the court doesn't have the shadow of these families behind us? We poor people, no matter how talented we have, no one can only stay in this field for the rest of our lives." The village chief shook his head and looked at it again.

Zhao Chen sighed softly.

If all the people can take the scientific examination, why should Brother Zhao run a tavern in Chang'an City with such a talent?

"Village Chief, don't say these words in the future." Zhao Chen and the village chief instructed.

Of course these people would not say anything, but if the rest of them heard it.

That would be a big disaster.

"The old man was a little proud today. Brother Zhao, we went to the fields to release water. I remember everything you said." The village chief nodded and said.

He just held a grudge for Zhao Chen.

If Zhao Chen could participate in the imperial examination, it would definitely be a blessing for the country in the Tang Dynasty.

pity……

The village chief said goodbye to Zhao Chen, shook his head and went to the field.

Li Shimin stood there and never spoke for a long time.

The Tang Dynasty inherited the imperial examination system of the previous dynasty and thought that it could attract all the talents of the world, but the people at the bottom did not even have the qualifications to participate.

If I hadn't heard of these things, how could I believe them?

Li Shimin thought of some of the previous things and felt extremely bad.

...

When I returned from the field, it was noon and everyone was tired.

After resting in the house for a while, Uncle Fu arranged for a meal.

The dishes were delicious, even if Queen Changsun felt uncomfortable, she ate a few more bites.

Only Li Shimin, who doesn’t know the taste of food and has a stagnant eyebrow.

"Husband, what's wrong with you?" Empress Changsun couldn't help but feel a little worried when she saw Li Shimin like this.

Li Shimin came to his senses, smiled at Empress Changsun, and looked at Zhao Chen again.

Zhao Chen was having a meal, but he didn't notice Li Shimin's gaze at all.

"Well, Zhao Chen!" Li Shimin said.

"What's wrong?"

"The cottage is behind." Zhao Chen replied without raising his head.

"Cough cough cough cough cough-" Li Shimin coughed violently, obviously he didn't expect Zhao Chen to answer him like this.

The other people almost choked Zhao Chen's answer.

When I was having a meal, I actually said this!
