"Sit down!" Lord Lu looked at Lin Yichuan with gentle eyes and said.

Lin Yichuan walked over tremblingly, and only a third of the official hat chair was seated.

"Relax, relax." Lord Lu looked at the nervous Lin Yichuan and said, "I read the file you handed over, and it is very well written." ”

Lin Yichuan hurriedly stood up and arched his hand, "The lower official has thanked Lord Lu, and please advise." ”

"Sit down, sit down, it's the duty of the house." Hearing this, Lord Lu pressed his hand down, and asked curiously, "Your file is different from the past, it is not so literal." Looking at the people who were about to stand up again, he said, "No, just sit down and talk." ”

Lin Yichuan, who was already halfway up, sat back, "This is more intuitive, clear and clear." ”

"That's right!" Lord Lu smiled when he heard this, "The afforestation and windbreak you mentioned in the file can really block the wind and sand. ”

"Yes!" Lin Yichuan looked at him with a firm look in his eyes and said, "Xiaguan has listed the facts and data in the file. Fucheng is not affected because of the dense vegetation and because it is in the north of Xiangping County. Referring to these, he was not nervous, and talked eloquently, "In the south of Xiangping County, it is greatly affected by wind and sand, and it is expanding every year." This is recorded in the previous local journal as a comparison. ”

"I watched." Lord Lu nodded when he heard this, "I have no opinion on planting trees to create windbreaks. ”

"That's great." Lin Yichuan stood up excitedly and said, his joy was beyond words, looking at Lord Lu with a stunned expression, he didn't give up, "The lower official has lost his temper." ”

"Sit, sit down and talk." Lord Lu looked at him mildly and said.

The messenger brought hot tea and a brazier, "Please slow down." He saluted with the tray and stepped back.

Two braziers surrounded Lin Yichuan, and he suddenly felt hot.

"Drinking tea, warm, warm, it's ginger tea." Lord Lu pointed to the tea cup on the small table and said.

"Yes!" Lin Yichuan picked up the tea cup on the small table and opened the lid, and the rich smell of ginger came to his nose.

Lord Lu was also embarrassed to stare at others drinking ginger tea, so he was even more nervous, so he said, "You drink slowly, I'll look at your file again." ”

"Yes!" Lin Yichuan drank a cup of ginger tea, put down the teacup and said, "Xiaguan finished drinking." ”

Lord Lu raised his eyes and looked at him and said, "As for the relief grain you mentioned, I can only fight for it a year ago, because the grain depot is not the final word of the government. ”

"The lower official understands, understands." Hearing this, Lin Yichuan stood up and bowed.

"After the year, the government will try its best to fight for it, and there will be more or less. So that the villagers will not go hungry to plant trees. Lord Lu looked at him with a glint in his eyes and said.

"Whether there is it or not, Xia Guan will thank Master Lu first. When the green and yellow are not received, this is the timely rain! Lin Yichuan looked at him gratefully and said, "The lower officials will lead the villagers to plant this windbreak." ”

"Good! Just do it! Lord Lu said strongly supportively.

"Thank you, Lord Lu, for your support." Lin Yichuan looked at him with emotion and said.

"Sit, sit down and talk." Lord Lu looked at Lin Yichuan, who was still standing, and said with a smile.

Lord Lu looked at Lin Yichuan, who was sitting down, and said, "Yichuan, you said that this windbreak, can it be used in the Northwest Desert." ”

"It's hard to say, but as long as there is soil and water, and the tree can live, then it will definitely work." Lin Yichuan blinked when he heard this, and hurriedly replied, "Xiaguan thinks it's good to plant trees in Guanzhong first." ”

"Guanzhong?" Lord Lu looked at him in surprise and said, "How did you think of Guanzhong?" ”

"On both sides of the Yellow River, to be exact." Lin Yichuan looked at him excitedly and said, "The land over there is seriously desertified, and this rain, the rain has washed the loess into the Yellow River." Then he said, "The water is turbulent, and the sediment is washed away, but when it comes to the Central Plains, the river is gentle, and so much sediment is not carried away by sufficient water, so it can only be silted in the downstream river, so the downstream river is silted higher and higher, and the accumulation is shallower and shallower." The shallow river cannot carry a large amount of water, and it is only a matter of time before the Yellow River overflows, just waiting for an opportunity – such as a heavy rainstorm. After thinking about it, he said, "Because of this, the Yellow River was diverted, and the silt piled up in the river, and the water flowed lower. Then he added, "The rivers of the lower reaches of the lower reaches of the Yellow River are often the channels of other rivers that have been seized after the last breach of the Yellow River." In the first year of the Later Jin Dynasty, the Yellow River broke to the southeast and directly rushed out of the 800-mile Liangshan Bo. The Yellow River in the Northern Song Dynasty continued to be incurable, and it broke at every turn. The river channel of the breach sometimes flows north, sometimes east, sometimes south, and sometimes several coexists, and it is impermanent. Later, the artificially burst the embankment, and the Yellow River channel in the front was constantly swaying on the southeast plain, snatching the rivers of Yingshui, Whirlpool, Suishui, Bianshui, and Surabaya back and forth, and occasionally breaking the mouth to go to the northeast for a walk. ”

"This one is going to the sea!" Lord Lu looked at him with dark eyes and said.

"Yes!" Lin Yichuan nodded when he heard this, "These rivers that were robbed by the Yellow River originally flowed slowly along their own rivers, although the river channel is not very wide, but the water flow is not large, but how can it accommodate such a large amount of water as the Yellow River!" The Yellow River is so forcibly stuffed in, of course, the flow of water is not smooth. Therefore, once there is a heavy rainstorm upstream, the water flow increases, and the lower part of the downstream begins to overflow. ”

"It's a novel statement." Lord Lu looked at him in surprise and said, "This Grand Canal is clogged with silt and needs to be dredged regularly!" ”

"Yes! Otherwise, the ship would not be able to sail. Lin Yichuan nodded hurriedly, and then added, "The most terrible thing is that once the Yellow River bursts into the Central Plains, it is equivalent to the widening of the river channel, and the flow of water becomes slower, resulting in a larger amount of sediment being left in the lower section of the downstream." Therefore, after the Yellow River bursts, the river channels below the breach are often directly filled into flat land. Now that the river is gone, the water of the Yellow River naturally flows low and wherever it goes. If you are lucky, the Yellow River will go directly to another river, and the matter will be over, and there will be a place to flow into the sea; Catch up with bad luck, and it is not a problem for the Yellow River to overflow in the lower plains for decades. ”

"In the past, the Yellow River flooded every year." Lord Lu nodded again and again when he heard this.

"Fortunately, the breach was blocked immediately, and fortunately, the river below the breach has not been filled, but after such a toss, this section of the riverbed is basically shallow and shallow, and after a few more floods, the life of this river will come to an end." Lin Yichuan said angrily, "The incident of the Yellow River breaking is not that it can be stable for many years with a single shot, but that it kicks its nose and face, and the more it decides, the more it is silted, and the more it is silted, the more silted it is." ”

"It seems that the ancients didn't have a good way to build dikes and build them higher and higher?" Lord Lu tapped his index finger on the table and said, "The Yellow River is still flooding, which is a headache. ”
