As a prefecture-level agricultural professional and technical school with a history of almost the same age as the Republic, Yunnan Central Agricultural School has been suspended several times, but adhering to the school motto of "Virtue, Integrity, Good Skills, and Practice", it still cultivates a large number of agricultural technical talents for the grassroots level, especially for the high-quality flue-cured tobacco production area in Central Yunnan.

Qi Jingtao is in charge of the informatization work of eight counties and one district of Nanyan Group Company in central Yunnan, and there are many grassroots scientific and technological workers and leading cadres who have graduated from Central Yunnan Agricultural School, and they are well aware of the influence and appeal of Central Yunnan Agricultural School in central Yunnan.

Father Qi Zhengming was able to connect with the provincial tobacco research base stationed in Bazi, the fifth district of central Yunnan, through the previous relationship, and established a cooperative relationship with the Central Yunnan Agricultural School through the relationship of the Tobacco Research Institute.

Qi Zhengming's management ideas are simply a stroke of genius, which can be compared to the advanced scientific management concepts of the integration of production, education and research in modern times. Qi Jingtao really didn't expect that his father was an ordinary farmer, he was so open-minded and far-sighted. He really hadn't talked to his father about these fashionable opinions, could it be that Qi Lin's girl gave his father's attention?

Teacher She of Yunnan Central Agricultural School is also a respectable old teacher, an old scientific research worker, who has a deep understanding of scientific research in the process of agricultural production. However, because his Central Yunnan Agricultural School is only a technical secondary school at the grassroots level, except for the flue-cured tobacco project research supported by the Provincial Tobacco Research Institute, the research funds of other research groups are not rich. Many of his research topics are stuck in his head or on paper, and cannot be put into experimental demonstration, in-depth research and experimental verification, and then transformed into results with practical value.

Teacher She really didn't expect that the ecological orchard contracted by rural villagers near a school would have such courage and reach a cooperation agreement with the school on teaching and scientific research bases. Not only is the name of the orchard novel and unique, and the word "ecology" is added ahead of time, but also has a unique style in the operation and management of the orchard, and the most surprising thing is that the funds are abundant. This is not at all a model of an orchard contracted by ordinary farmers, but a development model of large-scale agriculture.

When Ms. She first took the students to inspect the Granary River Farmland Water Conservancy Irrigation Project, she just felt that this relatively independent water conservancy irrigation system in the large mountain valley was very typical, and it was worth observing and studying from various perspectives. From the perspective of academic research, he proposed the overall sprinkler irrigation plan, mainly for his students to conduct research projects. He doesn't plan to recommend a holistic sprinkler irrigation scheme in a farmer's privately contracted orchard, because it's unrealistic, and it's not a big investment that an ordinary orchard can afford.

Unexpectedly, the girl who accompanied them on the inspection at that time was so attentive that she recorded the conversation between him and the students, and mentioned it to the son of the orchard owner Qi Zhengming. This seemingly impossible overall sprinkler irrigation idea was actually approved by him, and he also brought them a mature plan for their reference and research, and it was so easy to start entering the project implementation stage. Teacher She and his technical team are really flattered, and there is a feeling that pie has fallen from the sky, and it is still on their own heads.

The value of the teaching and scientific research base of the granary river began to be reflected, and once the overall sprinkler irrigation system was completed and put into use, its teaching and scientific research demonstration role was revealed. As an agricultural and technical school, it is not easy to have such a perfect teaching and research base.

And Qi Jingtao, the son of the orchard owner Qi Zhengming, not only fully supported him, but also provided a complete set of model plans for them to learn from, and the project funds allocated also included scientific research funds for their school. It was only natural that this project would be a research topic for their school. This project, if not well planned and designed, will be implemented seriously. I'm really sorry for the audience, I'm sorry for myself, and I'm sorry for my conscience.

Teacher She led his students to station in the Granary River and began their teaching practice, which also provided a large number of agricultural technicians for the construction of the Granary River Ecological Orchard. So that the granary river ecological orchard has a good starting point from the beginning, and a solid technical support.

With the stationing of personnel from the Agricultural Technical School, Qi Zhengming's stall is now getting bigger and bigger. All kinds of fruit trees are planted, vegetables are planted, medicinal herbs are planted, and millet spicy cultivation and breeding in central Yunnan that his son got for him. The number of people managed by this former production team leader is also increasing day by day, and the professional types and staff are not limited to ordinary rural villagers, but also other professional and technical personnel.

For the upgrading and transformation of the agricultural irrigation system that Qi Jingtao insisted on, he fully supported it after understanding the advantages and disadvantages. The only drawbacks of this project are that it is too expensive, the one-time investment is too large, the amount of water pipelines laid is large, and the others are all advantages and benefits.

Fortunately, Qi Jingtao is really not short of money now, and the sprinkler irrigation system that has killed many people's dreams will not be blocked by money. Moreover, there is now a new type of PVC pipe on the market that can be used, and the use of PVC pipe for pipe laying is much lighter than the cast pipe used in the past. As long as the water pipeline laying route is planned and designed, the laying speed of those construction personnel is very fast, and the difficulty of the operation is not as great as that of cast pipes and steel pipes.

Although it is said to be a whole sprinkler irrigation, it does not need to be built into a complete whole, as long as the water supply is not a problem, it can be divided into countless independent sprinkler operation areas according to local conditions. As an orchard manager, Qi Zhengming and his management team can flexibly control the actual water demand and carry out spray irrigation for different areas and different crops.

Zhang Jiayuan, who brought people to visit the progress of the sprinkler irrigation project, looked at the mist sprayed by the rotating sprinklers who were experimenting with spraying in the more than 1,000 acres of hillside land around the reservoir, and couldn't help but sigh: "Those villagers who came to help are blessed, coming to work in the orchard is like coming to cultivate, and they can easily finish the most tiring watering work before." ”

"They won't be idle, they won't have to be watered by so many people, and they have other work to do. On average, one person manages four or five acres of land, and when the tiring work is gone, the light work can be done more meticulously and seriously. Qi Zhengming explained with a smile.

"This is big agriculture, and now there are 17,800 acres of hillside land on three sides, and only six people need to control the sprinkler switch to complete the daily watering. Even if the canal is built into the ground, one person can use it all in the morning and evening, and at most two or three acres of land can be watered. There is no comparison, the efficiency of this sprinkler irrigation system is too good, it can save many people's labor!" Qi Jinghong spoke, calculating the sprinkler irrigation area and labor efficiency in his heart.

"You are talking about watering tobacco water, one acre of flue-cured tobacco planting about 1,000 tobacco seedlings, one scoop of water watering four tobacco seedlings to save life, a person can water two to three acres a day. Peppers are planted here, and at least 4,000 plants are planted in an acre of land, and it is remarkable that an acre of land can be watered by manual watering. Zhang Jiayuan silently calculated the water consumption of the plant in his heart and refuted the words of his old partner.

Qi Jinghong ignored Zhang Jiayuan's words, looked at the pepper seedlings that were bathing in the mist and sighed: "Fortunately, it is sprayed and watered, otherwise when the flue-cured tobacco transplanting in the village officially begins, where will I find so many people to water it." ”

Qi Zhengming explained beside him: "Originally, it was planned to regularly divert water into the ground for flood irrigation, otherwise it would not be watered at all. ”

"Flood irrigation can't solve the problem, it's okay in flat land, but what kind of flood irrigation can be done in hillside land? It's not good to lose water and fertilizer in high-lying hillside land, and low-lying places cause man-made waterlogging. "Teacher She was dissatisfied with Qi Zhengming's original plan, it was brutal.

"Teacher She, diffuse irrigation is just a saying. An average of 10 acres of land is built here to build a water storage tank, and when the weather is dry, a small area of water is used to irrigate the land, which can keep the mountain moist for several days, so that the amount of manual watering operation is not so large. Qi Zhengming patiently explained his local methods to Teacher She.

"Hehe, in the final analysis, it still requires a lot of manual work, and at most use the water pressure difference in the mountain reservoir to connect the water pipe to carry out manual local watering. Zhang Jiayuan said with a smile.

"Manual watering is not easy to control the amount of water and water pressure, the watering is uneven, and it is easy to overturn the crop. Spraying and watering is different, you see, the sprayed water flies up and spreads, forming a mist and falling down, the effect is like a light rain, moisturizing things silently,......"
