"Wisdom" Summer Management China Grain See China Harvest Map → National | Li Yuhuan | Wisdom
The three summer seasons of summer harvest, summer planting, and summer management are coming to an end this week. The large-scale machine harvest in the main wheat producing areas has basically ended, which also means that most areas have entered the summer field management time, which is commonly known as summer management. The summer tube is the last link of the three summers and also the key to abundant autumn grain production. As the saying goes, "three parts are planted, seven parts are managed.". So, what is the main focus of summer management in the "Three Summers"? Let's find the answer from the map.
Spring sowing, summer growing, autumn harvest, and winter storage are the experiences that Chinese people have summarized from life and work for thousands of years.
In summer, the scorching and full passion envelops the entire earth, and all natural things are lush and beautiful, growing vigorously, and crops are no exception. The farmers who have just finished summer harvest and summer planting have no time to spare. Summer is a crucial period for the growth, development, and yield formation of autumn crops, but it is also a time of frequent agricultural meteorological disasters and pests and diseases. Therefore, in order to ensure the healthy growth of crops in the field, good field management is necessary to ensure high grain yield.
After the wheat harvest, what is being planted in the fields now? Let's open the harvest map again. Today, on China's arable land, crops such as rice, corn, and soybeans are grown in the Northeast region; Cotton, corn, soybeans, and potatoes grow in the Huang Huai Hai, North China, and Northwest regions; And rice is cultivated in Jiangnan and South China; In the southwest region, the main crops are corn and rice. Regardless of the southeast or northwest, they are the hope for a bountiful harvest in autumn.
What does the summer pipe manage? If summer harvest and summer planting need to compete for time, then summer management is a delicate activity that needs to be scientifically and moderately adjusted according to the time and situation. For example, rice needs to go through nine stages from seed germination to harvest: seedling, transplanting, tillering, jointing, booting, heading, flowering and pollination, filling, and maturity. At each stage, it is necessary to refine the management of water, fertilizer, diseases, pests, weeds, etc. One step less management will directly affect the autumn harvest. The jointing stage of corn is a crucial stage for growth, and it is not necessarily better to grow taller. To achieve high yield of corn, it is necessary to control the height of the entire plant within a reasonable range, so that corn is not prone to lodging. Therefore, during the summer management period, it is necessary to spray "growth regulators" according to the actual situation to prevent small corn from growing taller. As for the high yield of soybeans, it is closely related to the rational use of foliar fertilizers, as well as the prevention of high temperatures and field waterlogging. In short, there is a lot of knowledge in field management. And modern agriculture is making this work more high-quality and upgraded.
Let's walk into the lush green rice paddies, where we can hardly see the figures of manual fertilization and pesticide spraying. Instead, there are drones buzzing in the air for plant protection. In the past, manual spraying was time-consuming and labor-intensive, but now it can be completed with only drone pilots operating on the edge of the field. Plant protection, which used to take 2 to 3 days to complete, now only takes half a day for drones.
With the upgrading of technology, drones have also gained new applications such as seeding and fertilization. Data shows that from May to June this year, over 30000 drones took off from the fields every day, adding wings to efficient and safe plant protection. Patrol is also a specialty of drones. With the help of the Internet of Things and big data technology, agricultural personnel only need to click with a mouse, and information such as soil moisture, crop growth, weather conditions, and disaster warnings from tens of kilometers away can be presented in front of them through a large data screen.
Summer is still a crucial period for cotton to bud, bloom, and peach blossom. In the cotton fields of Tumushuke City, Xinjiang, with the help of intelligent irrigation technology that integrates water and fertilizer, cotton farmers only need to open their phones to accurately implement water and fertilizer management, enabling the most efficient utilization of precious water resources in arid areas. The growth of rice cannot be separated from sufficient irrigation. This is the rice field in Yujiang District, Yingtan, Jiangxi. From the air, the irrigation project is well connected, and clear water flows continuously into the farmland through various channels, like "capillaries" in the farmland.
Behind the visible harvest lies more invisible care. With the help of technology, hardworking farmers better safeguard the hope of a bountiful harvest. The story of the Three summers unfolds every year, with the fields still alive and the hard work still present. To sow, manage, and cultivate, one can inevitably reap happiness through hard work.
Running "Three Summers" - Observing Harvest
Turning a grain of millet into ten thousand seeds is not only a matter of human effort and heavenly assistance, but also a new energy bestowed by modern technology. When we leap over the mountains and seas, overlooking the earth, we will see the unique scenery brought by the new agricultural technology in the magnificent field scenery.
In the mountainous corn fields of Pengshui, Chongqing, two drones are working together to spray pesticides on 40 acres of land in 8 minutes, eliminating the need for people to step deeper or shallower on the slopes. The corn in Pengshui Mountain is currently popping up. Drones fertilize in the air, moistening things silently, it's really high-level.
The rice in the 10000 acre demonstration field of Xiangtan, Hunan has just entered the filling period when the pest, the stem borer, arrived. The local "insect spy team" is a soybean on the field ridge. Soybeans are precisely the natural enemies of the stem borer. Another divine assist is these white "small cages", which contain potions that can make male stem borers come to ponder and be caught on the spot. New biological pest control techniques, starting from the roots, are more environmentally friendly.
Mango picking season, Guangxi is busy. In the 1.4 million acre mango forest in Baise, the fruits are bending their branches, causing busy picking by farmers, shuttle by trucks, and container transportation. Baise is the largest mango planting base in China, with one in every four domestically produced mangoes coming from here. Mango export requires strict storage and transportation conditions. A cold chain processing center and fresh cold storage have been established locally, extending the two month mango season to six months. Mango travels thousands of miles, and the mountains and towns become prosperous.
In the management area of Houhu Lake in Qianjiang, Hubei, crayfish pulled out of the water are celebrating. They are sent to the largest crayfish trading center in the country, where they are sorted and packaged, embarking on a global journey. Qianjiang emits 1500 tons of crayfish every day, approximately 70-80 million. About 3 million tourists come to Qianjiang every year to feast their mouths. Crayfish are supporting the industrial chain of rural revitalization.
The sky is vast and the wilderness is vast, and when the wind blows and the grass is low, I see cows and sheep. On the summer grassland of Aruhorqin Banner, Inner Mongolia, scattered summer camps are the homes of herdsmen for the next five months. They will spend the most beautiful season of the year on the grassland here. Cattle and sheep can also freely forage. The herdsmen switch fields and let the grasslands rest and thrive, and the grasslands generously repay them. Mountains, waters, forests, fields, lakes, grass, and sand, our home in beautiful China.
Li Yuhuan: I "fly a plane" in the farmland
44 year old Li Yuhuan is a drone pilot. She comes from Shihezi City, Xinjiang and is the first female pilot in the area to hold a certificate for operating agricultural plant protection drones. She not only flew by herself, but also brought out a group of apprentices. Now out of every 10 plant protection drone pilots, 8 are her students. Let's go see how she flies a plane in the farmland together.
At present, it is a critical period for cotton field management in Xinjiang, and Li Yuhuan is busy working in cotton fields of all sizes. After brief communication with the cotton farmer, she skillfully activated the drone and sprayed foliar fertilizer evenly and accurately from the air. Now, Li Yuhuan can accurately manage thousands of acres of farmland with a single plant protection drone. In addition to helping cotton farmers with field management, she has also been working hard these past few days to bring out new students.
Li Yuhuan always breaks down the flight essentials of handheld remote control devices, parameter settings, and route planning to explain them one by one. With excellent skills and diligent teaching, more and more people are coming to learn from her.
Five years ago, Li Yuhuan needed plant protection drones for field management on her family's over 1000 acres of farmland. When she had to wait in line for a month to find someone else to fly, she felt that it was time-consuming and not cost-effective, so she started learning plant protection drones. Since 2018, Li Yuhuan has flown over 100000 acres of farmland. At first, she was questioned, but later on, she received more and more orders. Li Yuhuan proved her strength through practical actions.
Plant protection drone pilot Li Yuhuan: The most questioned question is whether you, as a woman, can do it. Then many people came to watch you take medicine, but unexpectedly she did it quite well and slowly followed along. I am willing to tell them how to do it well.
In the past two years, Li Yuhuan has successively opened a plant protection drone shop and a maintenance shop, providing more technical services. In front of everyone, Li Yuhuan is a strong woman, and in front of children, she is an all-powerful "superman" mother. Every summer vacation, my daughter would follow Li Yuhuan to the field to watch her fly drones.
Li Yuhuan's daughter Zhu Ziyu: I often go to the field with her to get medicine, and I've seen it before. I think it's quite cool. For example, when the teacher mentions technology, I would raise my hand and say that my mother works in drones. I think this is a very proud thing.
