"I haven't seen you for a few months, you have more famous halls here, much more lively than ours, since Yuemin left, the Ishikawa Village Zhiqing Point is dead." At noon that day, Zheng Tong and Jiang Biyun came to look for them, and as soon as they came, they went around the freshly repaired biogas digester at the Zhiqing Point to study.

"The vegetation in northern Shaanxi is scarce, and it is not enough to rely on corn stalks and sorghum stalks, so we can only cut down those vegetation that are not much in the first place, and the natural environment in northern Shaanxi can only get worse and worse, so we must find new ways." Shen Long introduced, "I heard that there are educated youths in the county below Yan'an who have led the villagers to build a biogas digester, and I think this is a good way, so I checked the information, changed it a few times, and finally found something." ”

"The cement was all obtained from the exploration team, and the first biogas digester was repaired, and the next step is to promote it to the entire Ishikawa village, and then strive to make the whole Jingbian County use biogas." Why do people in northern Shaanxi live in caves, in addition to the fact that the soil here is relatively sticky and suitable for digging caves, there is also a very important reason.

It is the lack of large wood that can be used as a beam here, and the wood used to build a cave is much less than building a house, and even then there are many people who cannot afford to buy wood, and with a biogas digester, the already sparse vegetation on the mountain should be able to be denser, and in another ten years, it may be able to become a wood.

"Kui Yong, you can really toss, you are more powerful than Zhong Yuemin, I will tell the village when I go back, let them come and learn." Zheng Tong is now addicted to the world of books, he knows that this is good for the village, but he will not do it himself, maybe this is the limitation of intellectuals.

Shen Long originally wanted to talk to Zheng Tong about the silt dam, this kind of water conservancy project that is very suitable for the Loess Plateau in northern Shaanxi has begun to test and demonstrate in the 50s, and began to popularize in the 60s, and when the next century comes, the entire Loess Plateau has more than 110,000 silt dams, silting more than 4.5 million acres of dam land, which can intercept 21 billion cubic meters of sediment.

Soil erosion on the Loess Plateau has been greatly slowed down, and many sections of the Yellow River flowing through the Loess Plateau have been restored to be clear, which plays a very important role in increasing grain production, maintaining local water and soil, improving the ecological environment, and promoting local economic development.

I have been busy with the biogas digester and the exploration team for some time ago, but now I can finally free up my hands to prepare for this big project.

When Shen Long and his family were just going to build the biogas digester, the villagers were still ready to see jokes, they didn't believe that piling human and animal manure in the pond could solve the problem of fuel scarcity, but after several experiments, Shen Long successfully built the biogas digester, and Zhiqing Point had not used straw for cooking for more than half a month.

The construction of a biogas digester can not only solve the problem of fuel, biogas slurry can also be used as pesticides and fertilizers, and now there is a great shortage of chemical fertilizers in rural areas, and simple manure can only be used to grow crops.

To this end, Shen Long also deliberately set aside a small experimental field near the Zhiqing Point, which was specially used for irrigation with biogas slurry, and the crops in this experimental field grew much better than those in other fields, attracting the veterans of the village who were waiting for the crops to come and watch often.

They walked around the experimental field with their hands behind their backs, and they were amazed, these students from big cities are really amazing, not only do they know a lot of knowledge, but even they are better than these old farmers who have worked in the fields for decades.

No one laughed at Shen Long anymore, but Bai Mingchuan specially convened an enlarged meeting of the village committee to discuss this matter, and finally decided to allocate manpower and let Shen Long take the special construction of a biogas digester for the village.

In order to solve the problem of identity, Bai Mingchuan and the village committee unanimously decided to let Shen Long be the production captain, and Shen Long became the youngest production captain in the entire Hongwei Commune and even the entire Jingbian County.

After the biogas digester in the village was repaired and the first silt dam project was completed the following year, Baidian Village had become a model project for the entire Jingbian County, and people often came to visit.

At this time, the exploration work of the Baidian Village Coal Mine had already been completed, and the results of the exploration surprised them, the proven reserves were actually more than the Tongchuan Coal Mine, and according to the data that had been collected, this coalfield was likely to be just a corner of a super coalfield, and there were even larger coalfields around.

This directly alarmed the Ministry of Coal, from the province to the central government, there are constantly senior leaders to come to inspect, the development of the coal mine in Baidian Village was also quickly convened with their support, and a group of capable people were allocated to carry out the preliminary construction work in the future, Hu Jianjun also followed the team back to Baidian Village at this time, and he could meet Sun Xiaoxia every day.

Since the coal mine is to be developed, workers must be indispensable, and this coal mine was discovered by the educated youth and villagers of Baidian Village, so it is natural to give priority to them in recruiting workers.

Many young people in Baidian Village have been given the opportunity to jump out of the farm gate to become workers, and a few more educated youths have left, and although the rest are girls, there is still a need for female employees in the coal mine, who can be broadcasters, propagandists, and even financers, all of whom are literate and can count.

Shen Long and Qin Ling still did not leave, Shen Long had no interest in going to work in the coal mine, and the same was true of Qin Ling; This made the old and young masters of Baidian Village feel guilty, and in order to compensate them, Bai Mingchuan, who has now been promoted to the secretary of the Hongwei Commune, specially reported to the county and set up a public primary school in Baichuan Village, and Qin Ling became the official teacher of the school.

Shen Long became the village party secretary of Baidian Village, and when he became the production captain last year and led everyone to build a biogas digester and silt dam, Shen Long had already joined the party under the recommendation of Bai Mingchuan.

Although he is the youngest member of the village committee, since he came to Baidian Village, the changes brought to the village are obvious to all, the people in the village have gained so many benefits from him, and the days have changed dramatically compared with the previous two years.

As a result, after the youngest production captain, Shen Long became the youngest village party secretary in the entire Hongwei Commune and even in the entire Jingbian County.

When the Chinese New Year was about to be celebrated in 71, Shen Long took Qin Ling to embark on the train back to Beijing to visit relatives, and it has been more than three years since he came to northern Shaanxi in a blink of an eye, and they all miss their relatives at home very much.

"When I get to the capital, I'll go to your house to meet my uncle and aunt, right?" On the train, Shen Long said to Qin Ling that after the beginning of the year, the two of them would reach the legal age of marriage and could legally live together.
