Chen Shulan stayed in Kyoto for a few days, discussing with Chen Yaoguang and the others to refine the plan she had proposed last time. As for blowing the wind in Wang Guixiang's ears, Chen Guangyao will arrange someone to do it well, and it is not yet the time.

After Chen Shulan returned to Qianyuan County as she wished, she hibernated, like a poisonous snake, ready to wait for an opportunity to bite someone.

Time flies quickly, and winter is approaching in a blink of an eye. Although it will not be very cold here in Qianyuan County, there are elderly people and children at home, so you still have to prepare for winter.

Han Yixian made a lot of coal and firewood at home, and also made some charcoal, and burned a few charcoal pots when the weather was cold.

Han Yixian also plans to install a stove in the living room, so that several rooms can be heated with light in winter, and it is convenient to use hot water in winter.

This year, Qianyuan County has the leadership of Gu Qishen and Han Yixian, and their help has a lot more grain harvest, which has greatly alleviated the food shortage in Qianyuan County.

The main reason is that the grain seeds that Han Yixian helped transfer from City C are really good, and they are all high-yield grains. In fact, these grains are all provided by He Yuhan secretly, of course, very good.

Coupled with the scientific farming method handed over by Gu Qishen to everyone, the grain harvest in the village where Gu Qishen engaged in the experiment in Qianyuan County has increased by 30%, which is a big progress.

Seeing such good results, Gu Qishen plans to engage in scientific farming in the entire Qianyuan County next year, and also let the entire Qianyuan County use high-yield grain seeds.

The increase in grain production in Qianyuan County has attracted the attention of the city, and other counties have come to Qianyuan County to learn from experience.

Gu Qishen didn't hide it, after all, everyone's good is really good. He hopes that more places will be able to farm scientifically and increase grain production.

However, in order to increase grain production, not only the grain varieties must be good, but the fertility must also keep up. Then fertilizer is the top priority.

This year, Gu Qishen, a fertilizer factory in Qianyuan County, bought a set of fertilizer production equipment from L Province, and He Yuhan and Han Yixian helped improve the process flow, which greatly increased the output of chemical fertilizer.

At least at present, the output of chemical fertilizer can basically meet the needs of Qianyuan County.

But this is only the first step, the next step is to expand the fertilizer plant to expand production, radiation sales to the surrounding counties and cities to create greater benefits.

He Yuhan agrees with this. For a long time to come, chemical fertilizers will be in short supply of agricultural materials. At present, the output of the fertilizer plant is only to meet the minimum demand of Qianyuan County.

If you follow the amount of chemical fertilizer used in later generations, it is completely insufficient. For example, some plants such as soybeans need more urea, while corn, wheat, cotton, etc. need more diamine, and will also need compound fertilizer, and fruits are best to use sulfur-based compound fertilizer.

The use of chemical fertilizers should also be adjusted according to the different soil qualities. However, there is no such good technology to detect soil quality, and chemical fertilizers can only be used according to the general principle.

Nowadays, there is a lot of grain grown in rural areas, so urea and diamine can basically meet the requirements, and it is even better to produce some potassium fertilizer.

He Yuhan wrote a detailed report on the use of chemical fertilizers to Gu Qishen, which also gave Gu Qishen a deeper understanding of the use of chemical fertilizers. This makes farming in Qianyuan County more scientific.

In addition to chemical fertilizers, water conservancy is also needed to irrigate more farmland and increase food production. However, this water conservancy repair cannot be completed overnight, and it is a long-term work.

Gu Qishen also grasped this very tightly. In short, everything is in the service of increasing food production.

Gu Qishen will also regularly let people go to the countryside to publicize and organize the village committees of each village to learn scientific farming. It works great.

At the time of the harvest, looking at the joyful appearance of the farmers, Gu Qishen was also deeply infected. What could be more gratifying than having a full stomach when you are constantly going to starve?

Gu Qishen set a goal for himself, that is, to let the people of Qianyuan County have enough to eat in the future.

He Yuhan still works two days a week at the machinery and equipment factory, and works from home the rest of the time. In addition to designing new products, she actually spends most of her time learning.

At home, in addition to work and study, I also have to teach my children. She tries to make some time every day to teach the children.

Wen Jinyu also teaches children, and she also wants to reduce the burden on her daughter-in-law. Liu Zhongyi also joined Wen Jinyu's ranks.

Wen Jinyu and the others all saw He Yuhan's hard work, and He Yuhan would work late every day, and they all wanted to share some of it for her.

He Yuhan now not only designs new textile equipment, but also designs construction machinery.

While in City C, she designed two tractors and two excavators. Now the production and sales of these products are very good.

However, these two products were quickly studied abroad, and He Yuhan knew that his country's product sales would definitely be affected to a certain extent.

The products designed by He Yuhan are also designed according to the production capacity of this era, although they seem to be very advanced in this era, they are very backward in He Yuhan's view.

He Yuhan is now designing more advanced construction machinery to keep his country's products in a leading position.

In addition to excavators, He Yuhan also designed two agricultural machinery, namely seeders and harvesters. With these two agricultural machinery, it will greatly save manpower and improve production efficiency.

For example, harvesters do not need to be available in every village, but can be equipped with several in each township. When it is time to harvest grain, going down to various villages to work can greatly shorten the time for harvesting grain, and also avoid losses caused by untimely grain harvesting.

He Yuhan also designed several construction machinery such as loaders, road rollers, and graders. Now the country is overhauling roads, railways and other constructions, and these machines are very useful.

She wanted to provide these designs to Shuguang Machinery Factory. Because Shuguang Machinery Factory has basically had the strength to produce these machinery after this period of development.

He Yuhan has already contacted Shuguang Tractor Factory. The Shuguang Tractor Factory will soon send someone to contact her, and Jiang Bowen is among the people who come.

She hadn't seen Jiang Bowen for a long time, but they corresponded regularly. She knew that Jiang Bowen was now developing very well in Shuguang Tractor Factory, and he was already an important technician in the technical department.

This time Jiang Bowen came, she had to entertain her. She also prepared some materials for Jiang Bowen, all of which were materials on the machinery industry.

These materials did not bother He Yuhan a lot, because they were all sorted out by He Yuhan little by little. It is impossible for her to show the books of later generations directly to Jiang Bowen, so she can only sort them out by herself and then give them to Jiang Bowen. She also had to consider the security of these information, and not to bring danger to her and the Han family. So sorting out this information is a lot of brains for her.

She hopes that these materials will benefit Jiang Bowen and more people and improve the technical level of the domestic machinery industry.

Her strength alone is small, and only when everyone works together can we make greater progress.

Therefore, He Yuhan has a lot of things, and she always feels that she doesn't have enough time, so she often works until midnight recently, and she is busier than Han Yixian. Even Han Yixian was a little distressed about his daughter-in-law's fatigue.

But he knew that what his daughter-in-law did was very meaningful, and he had to support him strongly. So now he tries to go home as early as possible and go home to cook. If you can't let your daughter-in-law do it, you won't let it do it.

Through Han Yixian, the rest of the family also knows that He Yuhan has an important job now, so the housework at home is taken care of by everyone, and try not to take up He Yuhan's time.

In everyone's opinion, He Yuhan has done a big thing, and it is a very meaningful thing.
