Chen Shulan stayed in Kyoto for a few days, discussing and refining the plan she had proposed last time with Chen Yaoguang and the others. As for whispering in Wang Guixiang's ear, Chen Yaoguang would arrange for someone to take care of it, and now was not the right time.
After returning to Qianyuan County as she wished, Chen Shulan lay low, like a venomous snake waiting for an opportunity to bite.
Time flies, and winter is just around the corner. Although it won't be very cold here in Qianyuan County, we still need to prepare for winter because we have elderly people and children at home.
Han Yixian had gathered a lot of coal and firewood for the family, as well as some charcoal, and would burn a few charcoal braziers when the weather was cold.
Han Yixian also plans to install a stove in the living room so that several rooms can be heated in winter, and it will also be convenient to use hot water in winter.
This year, with the leadership of Gu Qishen and the help of Han Yixian and others, Qianyuan County has seen a significant increase in grain harvest, greatly alleviating the county's food shortage.
The main reason was that the grain seeds Han Yixian helped transfer from City C were of such high quality, all high-yield varieties. Actually, these seeds were secretly provided by He Yuhan, so of course they were excellent.
In addition, with the scientific farming methods that Gu Qishen taught everyone, the grain harvest in the villages where Gu Qishen was conducting experiments in Qianyuan County increased by 30%, which was a significant improvement.
Seeing such good results, Gu Qishen plans to promote scientific farming throughout Qianyuan County next year and to ensure that the entire county uses high-yield grain seeds.
The increased grain production in Qianyuan County attracted the attention of the city, and other counties came to Qianyuan County to learn from its experience.
Gu Qishen didn't hide anything, after all, everyone's well-being is what truly matters. He hoped that more places could adopt scientific farming methods to increase grain yields.
However, to increase grain production, not only do the seeds need to be of good quality, but the soil fertility also needs to be adequate. Therefore, chemical fertilizers are of paramount importance.
This year, Gu Qishen, the head of the fertilizer plant in Qianyuan County, strongly advocated for the purchase of a set of fertilizer production equipment from L Province. He Yuhan and Han Yixian helped improve the process flow, which greatly increased the fertilizer output.
At least for now, the production of fertilizer is basically enough to meet the needs of Qianyuan County.
However, this is only the first step. The next step for the fertilizer plant is to expand production and expand sales to surrounding counties and cities to create greater benefits.
He Yuhan agreed with this point. For a long time to come, fertilizer will remain a scarce agricultural commodity. Currently, the fertilizer plant's output only meets the minimum needs of Qianyuan County.
If we consider the amount of chemical fertilizers used in later generations, it would be completely insufficient. Some plants, such as soybeans, need more urea, while corn, wheat, and cotton need more diammonium phosphate and also require compound fertilizers. Fruits are best treated with sulfur-based compound fertilizers.
The use of chemical fertilizers needs to be adjusted according to different soil types. However, there isn't yet advanced technology to test soil quality, so we can only use chemical fertilizers based on general principles.
Nowadays, most rural areas grow grains, so urea and diammonium phosphate are generally sufficient to meet the requirements. Producing some potassium fertilizer would be even better.
He Yuhan wrote a detailed report on fertilizer use for Gu Qishen, which gave him a deeper understanding of fertilizer application. This made farming in Qianyuan County more scientific.
Besides chemical fertilizers, water conservancy projects are also needed to irrigate more farmland and increase grain yields. However, water conservancy projects cannot be completed overnight; they are a long-term undertaking.
Gu Qishen also focused on this aspect very closely. In short, everything was done in order to increase grain production.
Gu Qishen would also regularly send people to the countryside to promote scientific farming methods and organize village committees to learn about it. The results were excellent.
Seeing the farmers' joy during the harvest season deeply moved Gu Qishen. What could be more joyful than a full stomach when hunger was a constant threat?
Gu Qishen set a goal for himself: to ensure that all the people of Qianyuan County would have enough to eat in the future.
He Yuhan still goes to the machinery factory two days a week, and works from home the rest of the time. Besides designing new products, she actually spends most of her time studying.
Besides working and studying at home, she also teaches the children. She tries to set aside some time each day to teach them.
Wen Jinyu also teaches the children, partly to ease the burden on her daughter-in-law. Liu Zhongyi also joined Wen Jinyu in this role.
Wen Jinyu and the others saw how hard He Yuhan worked. He Yuhan would work very late every day, and they all wanted to help her share some of the burden.
In addition to designing new textile equipment, He Yuhan is now also designing engineering machinery.
While in City C, she designed two tractors and two excavators. These products are now selling very well at Shuguang Machinery Factory.
However, these two products were also quickly developed abroad, and He Yuhan knew that the sales of her country's products would definitely be affected to some extent.
He Yuhan's product designs were based on the production capabilities of this era. Although they seemed advanced in this era, He Yuhan considered them to be very outdated.
He Yuhan is now designing more advanced engineering machinery to ensure that her country's products remain at the forefront.
In addition to the excavator, He Yuhan also designed two other agricultural machines: a seeder and a harvester. These two machines will significantly reduce labor costs and improve production efficiency.
For example, harvesters don't need to be available in every village; a few can be provided to each township. When it's harvest time, they can be deployed to various villages to work, which can greatly shorten the harvesting time and avoid losses caused by untimely harvesting.
He Yuhan also designed several types of construction machinery, including loaders, road rollers, and graders. These machines are very useful now that the country is undertaking major highway, railway, and other construction projects.
