Wu Wei's improvement of the drilling rig is not only in power, but also in the supporting pumps. The use of pumping pumps in deep-water wells is actually very inconvenient, as a temporary disaster relief is still acceptable, if you want to promote or hand pressure pumps are better, he also asked manufacturers to come up with a solution, now there are many new wells using hand pumps, and will slowly replace diesel-powered pumps. In fact, Wu Wei's whole idea is to minimize the dependence on modern times, especially diesel and electricity, which are really head-scratching, after all, it is much easier to use overseas prevarication in terms of equipment alone.

Although Li Chong knew all kinds of things about Wu Wei, after all, he didn't often come to inspect outside the city, and some things were only heard, and today was the first time he saw it, and the surprise in his heart Cheng Dù was not necessarily much lighter than the prefect, but the expression on his face remained unchanged at all, and he looked like he was in control. Recently, Sun Jiaoyu often organized people to preach loyalty and filial piety in disaster victims' camps, and he was not surprised that he had seen a lot of various facilities.

Zhang Bangyan wanted to see the water conservancy facilities again, Li Xianling was familiar with this, because this was what he had personally experienced, and he was busy leading him to the irrigation canal, and he heard the water flowing from a distance, and when he looked around, he saw a sparse green in the field, and Li Chong introduced that this was the winter wheat that had not been sown for a long time, and the sparse and lala was the wheat seedlings that had just grown. When I got closer, I saw that the water channels in the fields were criss-crossed, and the water was gurgling and flowing, and in the distance you could see the farmers working with oxen, a scene of idyllic songs, and it was completely impossible to see that only a few months ago, the land was still cracked and the grass and trees were scorched.

Zhang Bangyan looked at the water diversion pipeline, and was surprised, there was a squire next to him who was funny, and said: "Qi Yu old man's ancestor, there is quite a field in the next family, and he is very suffering from drought, and he also uses this method to repair the canal to divert water. Zhang Bangyan was overjoyed and hurriedly asked him to lead the way to see. When we got to the place, everything was ready, and we only had to wait for the landlord to come and get water. Both ends of the clay pipe were plugged with something, and the pipe was filled with water, and the water filling place was sealed. A rope is tied to the head of the pipe leading to the irrigation canal, and the water can be passed by simply pulling it hard. From a distance, I saw someone waving a cloth banner at the upstream water diversion site, indicating that the filling at the end of the pottery pipe had gone. The squire held the rope with both hands and asked the prefect to operate it himself, and everyone in the audience smiled, secretly saying that this person was very good at sycophancy. Zhang Bangyan was also very interested in this, happily took the rope, pulled hard, and saw a turbulent water gushing out of the pottery pipe, and the onlookers were cheering loudly, and the prefect was also very happy.

I saw Li Chong step forward and said: "This canal was repaired in the Qin and Han dynasties, it has been abandoned for a long time, and the name has been lost and cannot be examined. This was discussed by Wu Wei and him before, originally Wu Wei meant to name it Li Gongqu, Li Chongjian couldn't resign, and the two agreed to name it Zhang Gongqu. The literati have a good name, Zhang Bangyan heard Li Chong say this, and couldn't help but be moved, but after all, his own family has no merit here, if he accepts it calmly, he is afraid that he will be ridiculed in the future, and he will not be humiliated when he asks for fame. He hesitated slightly, and immediately refused: "This canal is the work of your county, and my brother has no merit, how can he be greedy for this great name!" He waved his hand again and again, and mentioned that he called it "Li Gongqu". Li Chong resigned for a long time, and when he saw Zhang Bangyan's resolute attitude, he had no choice but to accept it, and everyone congratulated him for a while, and he was also so excited that his face was flushed.

In fact, the so-called "Li Gong Canal" does not refer to a single ditch, but is a general term for the scattered irrigation ditches in Ansai. These ditches have existed since ancient times, but they have been abandoned because the water source has dried up. If it is purely based on merit, it should actually be called "Wu Gongqu", but firstly, Wu Wei does not want this reputation at all, he just wants to keep a low profile now, and secondly, when he thinks of this name, he has a chill. Therefore, this great credit fell on Li Xianling's head, but then again, if it weren't for his strong support for Wu Wei, Wu Wei would not have acted so smoothly, and in this regard, naming it after him is not too outrageous. It is expected that this method will be promoted in northern Shaanxi and even all parts of the country in the future, and the name of Li County's order will also be widely praised. Thinking of this, Li Chong couldn't help but be secretly grateful to Wu Wei, this is a later story.

After seeing the irrigation canal, Zhang Bangyan was more interested, the terrain in northern Shaanxi is high, there are many highlands, and the method of taking water from Ansai is very useful. In fact, he is already preparing how to operate this matter, just now he asked about the method of taking water, Wu Wei came together, all detailed, not very difficult, Ansai has mastered this method of craftsmen and households, then can order Ansai County to organize to go to various places to guide and preside over is, Li County Ling and Wu Wei also agreed.

The last thing to look at is the potato field, the potatoes have all been harvested and returned to the warehouse, the reserved potato seeds have been properly preserved, and the remaining stems and leaves are left in the soil to easily cause diseases, and they have been collected to feed pigs and sheep. The vacated fields are planted with soybeans in season, and like wheat, they are sparse and have only just emerged. Soybean is not only a high yield, but also has a root system that fixes nitrogen, which can improve soil fertility, and is an important cash crop.

The most spectacular is the sweet potato field, although the sweet potato can only be harvested in November, there is still a period of time, but this thing is the most branched and leafy, the wide potato leaves will cover the whole potato field impermeable, looking lush from afar, it is gratifying! In this loess land of northern Shaanxi, this is really a wonder that has not been seen for a long time! Zhang Bangyan and the people below were all thrilled when they saw this.

After all, the Chinese nation has been cultivating land for thousands of years, and the land has long been clear inside and out. Moreover, after many years of drought, the peasants who are not skilled in farming have starved to death, and there are no people who are not skilled in farming, and the only thing that is limited is that there are no modern seeds, agricultural machinery, pesticides, fertilizers, and other materials. However, in order to adapt measures to local conditions, Wu guided them to adopt a variety of soil methods, such as soil chemical fertilizers and soil pesticides, and solved the problem of water sources and introduced improved varieties. As for tractors and other things at this time, hey, what the Zhuanghu people in this era have is strength, and what they eat is a hardship, you think it is a modern post-80s new farmer!

Therefore, everyone in Ansai is eager to learn, because they know that this is the way to live and live, and it is expected that after the victims return to their hometowns, they will be able to spread the learned methods widely, although there are no good seeds, but after solving the problems of water sources and pesticides and fertilizers, the drought in northern Shaanxi will not be enough to suffer.

Ask for collection, ask for recommendation, ask for reward, Wuchang fish group, thank you!
