"Mud, stone, sand!"

"Mud, stone, sand!"

The two sisters said in unison, Xiao Rui was dumbfounded: Is this the so-called twins?

"Is this kind of road good?"

Gu Qiqi glanced at Ning Xin'er and smiled with relief: "Of course it's good!" Build a roadbed with mud and stones, and then choose some coarse sand to spread on it, so that even if it rains, there will be no mud! ”

It's so easy to get sand!

Xiao Rui looked at the large river beach behind him and said: "There is a lot of sand, you will use local materials when you arrive, but it's a pity that the beach, if it is wasteland, it can be improved." ”

Ning Xin'er looked surprised when she heard this: "Brother-in-law, who said it was a waste?" There are a lot of things to grow in the sand! As long as there is enough water, good species can be grown! ”

Xiao Rui didn't believe it: "Planting can be planted, but as soon as the wind blows the sand, this thing is all covered with sand and dust!" ”

"Plant grass and trees! First cover the sand, fix the water and prevent sand, there is water here, what are you afraid of?"

Xiao Rui was curious: "If there is water, as long as grass and trees are planted on the sandy ground, species can be planted?"

This Ning Xin'er has done it many times in her dreams: "Yes, when there is no frost in February, we will sow grass seeds and plant saplings here, and we can plant a lot of things next year!" As long as it is cultivated well, the sand becomes an oasis as well! ”

Sand turned into an oasis?

This time, Xiao Rui was excited: "Sister, tell me, what can be planted in the sand?"

Gu Qiqi was curious when he saw him so excited: "Hey, you don't have any sand at home, what are you doing so excited?"

Xiao Rui smiled: "Qiqi, there is no sand in our house, but Cangxi has it!" As soon as you get out of Lingzhou Mansion, it will be sandy land, if you can turn those sandy lands into oases, do you think the people at the border will still starve?"

Gu Qiqi knew that it was not easy to transform a sandbar, she had only seen it, but she had never done it.

As for Ning Xin'er, she had only seen it in a dream.

Gu Qiqi thought for a while: "Xin'er, as far as you know, what can be planted in this sandy land?" For example, what tree, what grass, what species. ”

Ning Xin'er blinked and thought for a while: "The cultivation of sand land should be classified: pure sand land is different from what is grown in mud mixed with sand. What kind of sandy land is Cangxi that my brother-in-law said, do you know it?"

"Yes!"

Xiao Rui has been at the border for so many years, and he has a clear understanding of the land in Cangxi.

"There is pure sandy land, there is concrete sandy land, out of Linggu Pass until two hundred miles of the place is muddy and less land, the people there grow some miscellaneous grains, but the harvest is very low!"

Ning Xin'er listened: "In fact, some plants can be planted in two kinds, such as medicinal herbs, fruit trees, and peanuts." These are tough and easy to grow. ”

Xiao Rui was disappointed: "These can't fill the stomach, the fruit can't be preserved, and the peanuts are just snacks, is there no way to grow food?"

Ning Xin'er thought for a while, "Is it anything else, I won't be able to think of it for a while...... Brother-in-law, will you let me think about it?"

Xiao Rui nodded: "Okay!" ”

But Gu Qiqi said: "Don't think about it! If you can grow herbs, fruit trees, and peanuts at the border, I think it's all feasible! That's all good stuff! ”

Things are good, but compared to staple foods, these herbs and fruits can't fill your stomach, right?

"Huh?"

Gu Qiqi looked at Xiao Rui's eyes: "Do you remember the pills I gave you to soak and drink?" I made it myself. How about boiling different medicines with different recipes, and sick people can drink them with just boiling water?"
