Gao: the operation of spraying UAV in Chengdu is easier than that of remote control aircraft.

"Wow, it looks like a flying monster in Transformers." At 11:00 on the 19th, many citizens were queuing up to take photos with several drones of different sizes in the Sichuan Modern Agricultural Science and Technology Museum in Pavilion 4 of the Agricultural Expo.

"they are not only avant-garde, but also very useful." According to the staff on the spot, this is an eight-rotor agricultural plant protection UAV independently developed by Chengdu, which uses a high-efficiency brushless motor as a power and has a payload of up to 20 kg. Powered by large-capacity lithium batteries, the UAV can fly for up to 25 minutes and spray 5 mu of fields in a single flight. According to this speed, if the UAV works eight hours a day, excluding spraying and take-off and landing time, it can fly 32 times a day, spraying a field area of about 160 mu, equivalent to a week of manual spraying by eight people. At the same time, it can automatically hover and wait for rescue when the signal disappears.

"if it can be widely used, it will change the current situation of traditional farmers spraying pesticides in the fields little by little, not only reducing farmers' workload, but also ensuring that drugs can be evenly sprayed on every piece of land." The staff said that the operation of the drone is not difficult, it is simpler than the operation principle of the remote control toy plane, and the average farmer only needs one day's training to learn how to operate it.

In this 700 square meter exhibition hall, there are still many brothers of drones, such as solar water lifting units, agricultural remote sensing aircraft, light-driven agricultural machinery, automatic filling and other advanced agricultural equipment.

It is reported that at present, the main food crops in the demonstration areas of Guanghan, Pixian, Lu County, Renshou and other places in our province have basically realized the whole mechanized operation of cultivated land, sowing, fertilization, plant protection, harvest, drying and so on.

New: China's first aerial sweet potato can be harvested for three to five years.

Have you ever seen sweet potatoes ploughed in the field, but have you ever seen looking up to pick sweet potatoes? What is more amazing is that this kind of sweet potato is not a crop every year, but a seedling is planted and harvested for three or five years in a row.

In the Sichuan Modern Agricultural Science and Technology Museum, you can see a string of "red lanterns" hanging in the air, which are sweet potato roots connected with branches. This kind of sweet potato, which makes use of the growth characteristics of sweet potato and its related species, uses grafting technology to block the transport of photosynthate not to the underground root, but to accumulate in the aboveground part, and the air sweet potato is induced by pressure. The technology is the first at home and abroad. Two patents have been obtained in China.

Li Ming, a researcher at the Sichuan Academy of Agricultural Sciences, said that aerial sweet potatoes have three characteristics: first, they are cultivated in the air with soil, with low cost and convenient management; second, the growth mode of handstand hanging makes the roots grow upward and increases the ornamental value; third, as long as the sweet potato varieties can be cultivated with soil in the world, they can rely on this.

These techniques are cultivated in the air, "and the contents of vitamins and other vitamins of sweet potatoes in the air are higher than those of ordinary underground sweet potatoes."

Li Ming said that sweet potato seeds stand in the air in flowerpots. When the roots mature and pick sweet potatoes, we only need to take off the flowerpots and cut off the roots of sweet potatoes we want to harvest. After putting on the flowerpots, the vines can continue to produce sweet potatoes. Moreover, under reasonable culture conditions, the plant life of air sweet potato can be extended to 3 to 5 years, and can be harvested every year, and each upright growth site can produce more than 5 kg sweet potato.

Strange: 1400 jin heavy ecological fat pig does not eat feed to eat microorganisms

Have you ever seen a pig weighing 1400 jin? On the first day of the opening of the Agricultural Expo, the Nanchong Pavilion in Pavilion 2 was packed with people pointing their mobile phones at a behemoth in the iron cage.

"Why is there such a big pig?" "did you take hormones or additives?" "can it run?" Surprised, some people scooped up the crowd and found the staff in the museum to solve their curiosity.

The reporter approached and saw that in the cage nearly 3 meters high, a pig nearly 2 meters long slept on a thick mat similar to rice, with a white skin and soft fine hair. It rarely gets up and looks "lazy". Some citizens put their hands in and poked him. Someone pulled at his ears. He suddenly raised his head, turned around and lay down again.

"this pig weighs 1400 jin." Gong Dongfu, general manager of Nanchong Laida Ecological Technology Co., Ltd., said that it usually stands up and plays, moves flexibly, but is fat but not bulky. "in fact, it is an ordinary pig breed, but it eats microbes." Gong Dongfu explained that this pig is the experimental product of the company's "extreme feeding". There are more than 40 "extreme pigs" in the company, and the heaviest one has been raised for more than five years and weighs more than 1600 jin.

Unlike ordinary pigs, these pigs ate grain degraded by microorganisms, drank microbial solution, and slept on microbial mattresses with a thickness of 50 centimeters. Due to the use of beneficial bacteria in microorganisms to kill harmful bacteria, pigs get sick less, even not sick. "compared with pigs of the same age, he is stronger and younger." Gong Dongfu said with a smile that the meat of this kind of pig is fat but not greasy, thin but not stuck, and the market price is 30 yuan per jin.
