Prices fluctuate, "Potatoes are crazy"
Inner Mongolia is China's largest potato base and its output accounts for about one-seventh of the country’s total production. However, no one thought that in 2010, the price of potatoes in Inner Mongolia rose to 2 yuan per kilogram, which was dubbed by the media as “golden eggs†in the land; in 2011, the price of potatoes plunged by 2/3, and “golden eggs†changed overnight. Has become a "soil dumplings." Crazy Potatoes got its name.
The “high price†potatoes in 2010 led to the “thorny and hurt peopleâ€. Zhang Jun, a Beijing citizen, was born in Helinger County, Inner Mongolia, a potato village. Eating potatoes is his family's favorite, and almost he can't live without potatoes. However, the "high price" potatoes of the previous year had forced his family to adjust their recipes and changed to three meals a day for a meal. Zhang Jun said: "Potato prices rose to two or three bucks a pound, really can not afford to eat."
The plunge in potato prices in 2011 has also triggered "dwarf farmers." Wei Xiulian of the Weichang Manchu Mongolian Autonomous County in Hebei Province last year contracted 1,000 mu of farmland with 6 relatives in a farm in the Zhengling Lanqi 5 in the Xilinguole League. The result was totally lost. Wei Xiulian said: "Last year one acre land lost 1,000 yuan, 1000 mu land lost 1 million yuan."
Wei Xiulian is not the only victim of "crazy potatoes." Reporters learned that in the major potato producing regions such as Hohhot, Wulanchabu and Xilin Gol League in Inner Mongolia, most of the farmers with small plantings and less investment have “zero income†or slight losses last year, and most of the flowers Planting large households investing in large amounts of money generally cost hundreds of thousands of yuan to millions of dollars.
Large family in the small market exits, "Potato planting fever" cooling
At this time of 2011, Zhang Yiyi also looked forward to the realization of his wealthy dreams in the potato fields with two newly bought farm machinery; now he is looking for buyers for them everywhere in the villages surrounding Ulan Qab. He sighed and said: "Last year there was a lot of losses and I just gave up."
Zhang Yiyi, a businessman from Jining District of Ulan Qab City, last year turned his gaze to a strange potato industry. He invested hundreds of thousands of yuan in Dongfangzi Village, Shangdu County, not far from his hometown, and rented more than 300 acres. potato. He calculated that even if the price fell by half from the previous year, it would be profitable. What he did not expect was that the price of potatoes plunged from around 2 yuan per kilogram in 2010 to 0.6 yuan per kilogram in 2011, allowing him to lose more than 400,000 yuan a year. "Last year's debt has not yet been paid off. This year we can only sell the agricultural machinery without planting it."
Similar to the situation of Zhangyiyi, many big farmers who grow potatoes in Baotian also began to withdraw from the market or reduce production to varying degrees. Most of the farmers who have a small area of ​​planting and less investment also have a fear, and their willingness to plant has declined significantly. Kang Rui, a farmer in Zhongyingzi Village, Wuchuan County, Inner Mongolia, planted 100 mu of potatoes last year and plans to reduce it to 60 acres this year. In addition, there are more than 120 potato growers in the production and marketing cooperatives of Fukang Agricultural Products (12.30, -0.34, -2.69%) in Wuchuan County where he lived. Last year, a total of 6,000 mu of potatoes were planted, and this year it is planned to be reduced to about 4,000 mu.
Market supply and demand balance, potatoes return to "way vegetable prices"
During the interview, both farmers, government officials and industry experts said that the reduction in potato planting area in 2012 is a foregone conclusion, with a decline of 20% to 40% and a corresponding reduction in production.
According to the data provided by the Ministry of Agriculture and Animal Husbandry of Inner Mongolia, in 2011, the planting area of ​​potato in Inner Mongolia was 10.69 million mu and the output was 10 million tons. If we reduce the planting area by 20% this year, the output will also be reduced to about 8 million tons, which is exactly the level of 2008 and 2010.
Tang Zhaohua, secretary-general of the Inner Mongolia Potato Association, said: “Last year, Inner Mongolia increased production by about 20%, causing prices to plummet. If we reduce production by 20% this year, we just lose the unreasonable part and the price should return to rationality. I think the purchase price should be back. To about 5 cents per catty, this is about the same as the normal year's price, and it will be about 1 buck to the consumers."
Most potato growers are also optimistic about the 2012 prices. They believe that the supply and demand of potatoes will tend to be balanced in 2012, and the prices will return to the “highway vegetable prices†level.
We may have ever heard of the Bullet Fixed Focus Camera/ Fixed Focus Bullet Camera HD/ Bullet Fixed Focus Journal Camera/ Fixed Focus Bullet Camera IR/ Fixed Focus Bullet Surveillance Cameras/ Fixed Focus Analog Bullet Cameras, so what is the Bullet Fixed Focus Camera? We know that the Bullet refers to the camera shape, so what about the Fixed Focus? Actually, the Fixed Focus refers to a type of the camera lens. Today let me introduce the camera lens for you.
The camera lens is the key equipment of the video system. The lens' quality (index) directly affects the overall index of the camera. The lens is equivalent to the lens of the human eye. As you know, if there is no lens, the human eye cannot see anything. That is to say, if there is no lens, then the output image of the camera will just be white without any clear image output; which is consistent with the principle of our home cameras.
Actually, there are many classifications for the camera lens. Today please let me introduce one classification for you---the classification according to the structure.
1. The fixed focus lens with the fixed aperture
The lens has only one focus adjustment ring that can be manually adjusted. Rotating the ring left and right can make the image on the CCD target surface clearest. There is no aperture adjustment ring, so the aperture cannot be adjusted, and the luminous flux entering the lens cannot be changed by changing the lens factors, but can only be adjusted by changing the illuminance of the shooting site. The structure is simple and the price is cheap.
2. The fixed focus lens with the manual iris
Compared with fixed focus lens with the fixed aperture, the fixed focus lens with the manual iris has an extra aperture adjustment ring. The aperture range is generally from F1.2 or F1.4 to fully closed, which can easily adapt to the illuminance of the shooting site, and the aperture adjustment is done manually. The illuminance is uniform and the price is cheap.
3. The fixed focus lens with the automatic iris
Compared with the fixed focus lens with the manual iris, the fixed focus lens with the automatic iris has an extra gear-driven micro motor on the iris adjustment ring, and a 3 or 4-core shielded wire is drawn from the drive circuit, then connected to the camera's automatic iris interface seat. When the luminous flux entering the lens changes, the charge generated by the CCD target surface of the camera changes accordingly, thenthe video signal level changes, and a control signal will be generated and transmitted to the automatic iris lens, so that the motor in the lens can perform the corresponding rotation to complete the task of resizing.
4.The electric zoom lens with the automatic iris
Compared with the fixed focus lens with the automatic iris, the electric zoom lens with the automatic iris two extra micro motors. One motor is connected with the zoom ring of the lens, and can control the focal length of the lens when it rotates; the other motor is connected with the focus ring of the lens, and it can complete the focus of the lens When it rotates with control from the former motor. However, due to the addition of two motors and an increase in the number of lens groups, the size of the lens has also increased accordingly.
All in all, it would be helpful to know about the camera lens if you want to know more about the Bullet Fixed Focus Camera and the whole video monitoring field.
