It starts with the production team driving the big truck

Chapter 196 There are talented people among these farmers!
Sun Jianping helped Cao Chungui to carry the resold grain "bought" with white strips from the commune grain depot to the east room. The forty kilograms of grain per month as a subsidy to the educated youths were also handed out. They were piled together, covered by the sunlight outside the window. If you take a photo, it looks like a bunch of golden bumps.

"This is enough to last for a while." Li Xiuzhi watched her husband and elder brother carry food into the house, and her frown gradually relaxed. With more than a thousand kilograms of food, she will wait until spring to get some wild vegetables and elm money. Something like that, at least we can get through this spring famine.

Now the whole village is counting on the land in the valley to grow rice and solve the food problem!
"That's what I think, let's cultivate like this..."

Yu Changhai led the technician sent by the superior - a little old man in his sixties, with messy hair, wearing a pair of old black-rimmed glasses, the temples had been broken, and had been wrapped several times with yellow tape - sitting in front of him. On the edge of the kang in the house, he pointed at the drawings left by the little devil and discussed how to build this canal.

"To build a canal, you must first determine the level of the water level. Have you confirmed this issue in the route you designed?" Lao Huang adjusted his glasses and asked.

"It's settled."

"How are you sure? You don't have professional equipment?"

Lao Huang felt that these farmers were bragging a little too much, so he scratched his hair and asked. Lao Cao told Sun Jianping the trick of lighting torches, which made Lao Huang smack his tongue!

He actually thought of using this method to determine the height of the ground!

There are talented people among these farmers!
"According to my opinion, we will use blasting to start construction early so as not to miss the farming season." Old Huang adjusted his glasses and saw Li Xiuzhi bringing the food. He pursed his lips and subconsciously leaned against the wall.

"Teacher Huang, let's have some together!" Li Xiuzhi also called him that. Old Huang blushed and scratched his cheeks in embarrassment, "You guys can eat, I ate before I came here."

"You're welcome, these are not outsiders!" Lao Cao chuckled, "Try my old daughter's craftsmanship!"

A plate of fried yellow eggs exudes an alluring aroma, the soft and tender steamed chicken cake is tender and attractive, which makes people appetite just looking at it, coupled with a pot of golden welted corn pancakes, Lao Huang The glutton in his stomach was aroused, and he glanced at Yu Changhai timidly, then lowered his head, "You guys, eat, I'm not hungry."

"Come and have something to eat. You're welcome when you get home!"

Lao Cao winked at Sun Jianping, and Sun Jianping grabbed his wrist, half dragged and half pulled him to the table, and handed him a pair of chopsticks.

Lao Cao glanced at Yu Changhai again, and Yu Changhai said haha, "You can eat if you are told to, haha. When you are full, let's go to the fields to see. Whether the canal is well built or not depends entirely on you, Lao Huang!"

"Thank you for your trust, leader!" Lao Huang nodded and bowed repeatedly, making everyone in the Cao family frown.

Li Xiuzhi served him a bowl of soup. Lao Huang took it, brought it to his mouth and took a sip. He looked at the bottom of the bowl and saw a poached egg lying underneath.

The old man's eyes were a little moist, and he glanced at Yu Changhai quietly, then ate the egg with a slurp. Looking at the bright sun outside the window, Sun Jianping saw a drop of crystal water falling on the old man's eyelids, and then slipped into the rice bowl.

Ugh!
After eating and drinking, Sun Jianping got into the car and led everyone straight to the saline-alkali land in the valley. Lao Huang squatted on the ground, rubbing his belly from time to time and burping. He had eaten too much just now and felt a little uncomfortable. He lay on the ground, squinted his eyes, and compared with his hands to test the height of the ground. After some comparisons, he was shocked to find that the route Sun Jianping tested was completely correct!
"The outlet must not be chosen in the middle reaches. This is a sandy river beach. Once the amount of water is too large, it will hollow out the bottom of the river bed, causing a dam failure. Then the canal will be repaired in vain..."

Lao Huang walked to the Gulu River again, followed the river all the way up, and finally found a stone river bed. He pointed excitedly with his finger at the gurgling river water, "It's right here. Just open an opening here and put it in." The river water pours into the land in the south along the channel, and the fields can be automatically irrigated!"

He took the drawing, squinted his eyes and looked at it carefully, and was shocked to find that the area he pointed at had also been marked with a red dot!
This is a bit...

"It's pretty much the same as what our Jianping said!" Lao Cao laughed. The level of "big experts" from this provincial capital is average!

"Young man, you've already done a good job, haven't you?" Lao Huang asked Sun Jianping, and Sun Jianping smiled, "I just read some books on water conservancy, so I was blind."

"You're not blind..." Old Huang tilted his head and looked at him carefully several times. Sun Jianping felt uncomfortable all over. Just as he was about to leave, he was stopped by the old man, "I think you have already thought about this canal." How do you fix it? Tell me!"

"Let me tell you..." Sun Jianping scratched his head and smiled, "I am also a layman, so please forgive me if I don't speak well."

"Be polite, communicate with each other, and learn from each other!"

Sun Jianping walked to the river and pointed to the flowing water, "Although the river bed here has a stone bottom, the bank bases on both sides are still alkaline soil. If a hole is dug from here to build a canal, once the water flow is too large, it will still be washed away. The bank foundation will cause floods to overflow. My opinion is..."

"Go on!" Lao Huang urged with a smile.

"Learning from the experience of Li Bing and his sons in building Dujiangyan during the Warring States Period, they made baskets and loaded them with large stones to sink into the water. They divided the river water into two parts according to the ratio of 28 to 28, and used the small outer flow to introduce it into the canal for irrigation. The main water flow still flows with the river, even if There is too much water during the summer flood season and it will not cause much harm to the canals.”

"anything else?"

"After the river was divided into two, the right bank was also reinforced with gabions. After the river was narrowed, the flow rate accelerated, which would deepen the river bed, causing a difference in water levels between the inside and outside. In this way, once the water level drops due to drought, the main stream will The water will also flow to the tributaries, and it can still be diverted into the channels, which is very convenient..."

"good, very good!"

Lao Huang gives a thumbs up!
This guy is truly a water conservancy genius!
The idea of ​​splitting the river water in two and using the natural flow rate for diversion irrigation is an ingenuity that no one can imagine even if they break their brains!
"This is just a water diversion project. I have some immature views on building downstream channels." Sun Jianping pointed to a line that has been sprinkled with white lime and is about to start construction. "The three miles between here and the lower depression The land is flat and the slope is less than ten degrees. If it is built in a straight line, the water flow power will be insufficient, which will affect the water supply and cause a large amount of sediment to be deposited in the channel. The channel will be useless in a few years."

When everyone heard this, they all squinted their eyes to look at the lower depression in the distance. Everyone broke into a cold sweat at the sight!
I just thought about fighting against the heaven and earth to build the canal, but I ignored this matter!
"Jianping, tell me if you have any good ideas!" Cao Chungui urged him anxiously, squeaking at him.
