This time.

Li Shimin wanted to answer at once.

Who made him the son of heaven.

In a word, who dares not follow?

However, Li Shimin hesitated at the thought of the five surnames and seven clans and the guannong, plus the gentry in Shandong, the big family with thousands of acres of land, and the mysterious hands behind everything.

This thing is really big. It's not big, but the key problem is.

What is it?

"I said Feng Zi, can you tell me what you're talking about?"

Zhang Feng did not intend to be able to hide it. He did not shy away from saying, "it's the screening of seed species."

"Yesterday, I put wheat seeds, almost 100 kilograms of seeds. Do you know how many excellent seeds I screened out?"

The Li Shimin didn't know. He spread his hands and said, "you say! Where do I know these things?"

Zhang Feng touched his nose and said, "among the 100 kg seeds, I only screened out 30 kg seeds with full particles!"

This time, Li Shimin understood everything

No wonder Zhang Feng used to use flower seeds as an analogy. Was that what he said?

But a hundred pounds, leaving only 30 pounds, is this a little too much?

What about the remaining 70 Jin?

How much food does that waste?

Zhang Feng saw the uncertain look on Li Shimin's face, motioned Li Shimin to keep up, and then they came to the farm, which is now the agricultural product incubator.

At the gate of the Incubation Park, there were already five big and thick men stationed, but the chickens, ducks and pigs in the park had long disappeared. On the gate, a prominent wooden board wrote in scarlet characters: "the important place of the Incubation Park, no admittance!"

In the park, Lao Gao sits on a stool and doesn't go anywhere. He sits in front of the land cultivated by Zhang Feng. The floating dust in his hands that used to drive away chickens and ducks has become a sharp tool to drive away birds. As long as birds dare to come, it is difficult to escape Lao Gao's floating dust.

Zhang Feng also admired Lao Gao's eyes.

It looks like people in their 70s and 80s, but the eyes are really more vicious than ordinary people.

Around Zhang Feng's land yesterday, it was surrounded by brand-new bamboo fences early, even for good differentiation,; Lao Gao also put up a card in this place.

He wrote, "master Dean, no one is allowed to enter the land. Those who violate the order will be expelled from the mountain!"

good heavens.

Looking at this scene, Li Shimin was startled.

"Feng Zi, what exactly have you planted in this soil?"

The voice here also disturbed Gao and the guard. When they saw Zhang Feng coming, they hurried to kneel down, but what about Zhang Feng's rules? They just gave a standard military salute to Zhang Feng, which was different from Lao Gao.

Naturally, he knows Li Shimin.

But at this time, seeing the emperor arrive suddenly, I instinctively want to bow down, but it's wrong to think about it. The thief's posture at this time is ugly.

Zhang Feng also looked at Lao Gao curiously and said, "Lao Gao, what's your posture?"

What can Lao Gao say?

I can only get up and hug Li Shimin and say, "I've been doing nothing lately. I've studied a set of tricks."

Zhang Feng is a little confused.

But this is not the time to say this. I pointed to the yard and said, "today I'll ask Lao Li to see our masterpiece yesterday. You can do whatever you should do."

After Lao Gao left, Zhang Feng opened an entrance and exit of the fence and took Li Shimin into the wheat field.

But as soon as he entered the wheat field, Li Shimin smelled a strange smell and asked curiously, "did you use phosphate fertilizer in the wheat field?"

"Smart!"

Zhang Feng nodded and said, "I really used this thing. I've seen the old house before. You don't know. We went to the farmland outside Chang'an city. Guess what kind of makers in this land have a low income in Guangzhong?"

"Low income in Guangzhong?"

This Li Shimin really doesn't know.

This planting method has lasted for hundreds of years, at least thousands of years, and there has never been a problem, but why is it like this here in Zhang Feng?

Zhang Feng nodded and said, "look at the soil."

Zhang Feng pointed to the soil under his feet and said, "the soil here is good, because there has been no farmer before, and there is not much farm fertilizer, that is, the feces of pigs, cattle and sheep, and not much ash that burned the leaves of trees."

"So there are not many acidic substances in the soil. If I drink vinegar for you all day and keep drinking it, the rice is thick, the vegetables are also thick, and there are such things in the wine, will you feel comfortable?"

In that case, isn't that the same?

What's wrong with this?

Seeing Li Shimin's appearance, Zhang Feng patted his forehead and said, "I made a wrong analogy. I'll start again. Do you think you can be strong if you want to eat bran pharyngeal vegetables for you all day?"

Li Shimin understood this, but still asked, "but this is a way handed down by Yanyan's ancestors. Why not?"

"It's a good solution. Go to your accountant and ask the same one mu field. In recent ten years, you're cutting out the best harvest and the worst harvest. Calculate the gap!"
