On the afternoon of the 27th, in the Lujiaqi vegetable wholesale market in Guozhuang Town, Pingdu County, thousands of tons of Chinese cabbage were stored in the open air and simply covered with a layer of grasshoppers. The yard next to the collection of cabbages is also full of Chinese cabbage. “The Tudor is in the wholesale market. At this time in previous years, the road was full of tractors that had been collecting cabbage. Now there are no personal figures.” said Li Junsen, vegetable farmer.

The cold storage was full of cabbage

“Do you come to collect cabbage? How many tons? What price is it?” On the morning of the 27th, I heard news from reporters asking about cabbage growers. Li Junsen, vegetable farmer, Lujiaqiu Village, Guozhuang Town, Pingdu County looked forward with a look of hope. stand up. When he learned that the reporter was coming for an interview, he sighed long. “The Tudor is in the wholesale market. At this time in previous years, the road was full of cabbage tractors. Now there are no personal figures,” Li Junsen said.

On the afternoon of the 27th, in the Lujiaqi vegetable wholesale market in Guozhuang Town, thousands of tons of Chinese cabbage were stored in the open air and simply covered with straw. Next to a few cabbage collection points are also piled with Chinese cabbage. "It is full, there is no place." Cabaret agent Zeng Xiuhua said that several cold stores she can contact are full of cabbage, Guozhuang Town, Renzhao Town, Guxian County, Nancun Town and other areas of the cold storage of every household. All were stuffed with Chinese cabbage.

After investigation by the Qingdao Municipal Bureau of Commerce, about two-thirds of the households in Pingdu, Laixi and other places store cabbage. The reporter learned that Renzhao Town in Pingdu City has a storage capacity of several hundred thousand tons of cold storage. In the past, cold storage was used to store green onions, garlic sprouts, and other green vegetables. It sold at a good price during the Chinese New Year. Due to the fact that the cabbage was not sold earlier, the vegetable farmers stored the cabbage. According to the crude statistics of the Qingdao Municipal Bureau of Commerce, it is estimated that more than 100,000 tons of cabbage are stored.

“Looking at the weather on New Year’s Day, if it continues to be cold, Chinese cabbage may be frostbite and fall into the hands of vegetable farmers,” said Zhang Qing, deputy director of the Vegetable Office of the Qingdao Municipal Bureau of Commerce. On November 17, the purchase price of cabbage was 0.5 yuan per catty. Because of the Korean kimchi crisis at that time, Chinese cabbage was not sold. Many vegetable farmers refused to sell it. Some vegetable dealers had to go as far as Jiangsu and other places to enter cabbage. By November 27, a large number of cabbages were on the market, and vegetable farmers sold them at a price of RMB 0.35 per catty and they did not have to receive them.

Reasoning

The price in the early period skyrocketed and lifted appetite from farmers.

Lujiaqiu Village is regarded as a village for cabbage cultivation in Guozhuang Town. Almost every household has a vegetable field. In the past winter, the purchase price of Chinese cabbage was generally around 0.1 yuan per catty, but the vegetable prices this year left the farmers unable to understand. In late September this year, the town suddenly came to a lot of foreign merchants to book cabbage, local kimchi processing plant also began to book. From October to mid-November, vegetable vendors have been buying local cabbage. The price of cabbage per catty is getting higher and higher, at 0.45 yuan, 0.47 yuan, 0.48 yuan, and 0.5 yuan... "The cabbage was too hot for a while, and the vegetable grower was not even willing to lose a leaf. If you want to book cabbage, you must put the whole area. All packages are included.” In mid-November, many merchants commissioned cabbage agent Zeng Xiuhua to purchase cabbage. At that time, the price per catty went to 0.47 yuan, but the vegetable farmers refused to take it.

“They searched the internet and said that they will be able to break 0.5 yuan this year. Several villages around me have asked me to help find cold dishes. Now I have put more than a thousand tons of cabbage in my place, except for occasional retail investors. No one wants to pull cabbage outside the wholesale market," Zeng said. According to reports, due to the high price of local cabbage, vegetable farmers "reluctant to sell", many processing plants have to go to Jiangsu, Hebei and other places to buy cabbage. "The cabbage from other provinces plus shipping and labor costs cost 3 pounds more than a pound, but the price of cabbage 'wheat' here is about 3 pounds more." Zeng Xiuhua said that due to the previous period The skyrocketing price of Chinese cabbage has pushed up the psychological expectations of farmers. In the end, the first-aid waiters could only watch the price of cabbage grow from 0.5 yuan per catty at the highest price to 0.2-0.3 yuan per catty. “Chinese cabbage is collected at a high price of 0.46 yuan per catty and 0.47 yuan. Not to mention that nobody has come to collect it. Even if someone comes to collect it, the price is too low and we are not willing to sell it.” Cai Junnen, a vegetable farmer, looked helpless. Now, the vegetable farmers are waiting for the kimchi factory to quickly digest the stock in the factory, and then buy a large number of their cabbage.

Cabbage can be served until the end of April next year

Just as in the case of peace, there is a similar situation in cabbage in Mazhuang Town, Jiaozhou City. In previous years, the buyers of Shenzhen, Dandong, and Cangshan all disappeared suddenly, and they “flashed” the vegetable farmers of leeks. The kimchi processing company that can digest large quantities of cabbage has also caused inventory saturation due to the previous buying. “Chinese cabbage was already purchased as early as early December, and now the factory is mainly acquiring chili peppers.” The person in charge of Qingdao Yongfangyuan Food Co., Ltd. who processes kimchi said that due to the high purchase price of cabbage this year, the factory has already snapped up a large amount in advance. Cabbage. At present, the inventory of cabbage in the factory can be used by the end of April next year.

Engines

Motorcycle power devices are used in the internal combustion engine; people use diesel-fuel engine is known as the diesel engine, and the use of gasoline-fuel engine is known as gasoline engine. Because of the advantages of light weight, small volume, low noise, low vibration, easy starting and low cost, gasoline engine is widely used as its power device.

Two-stroke and four-stroke engine two-stroke engine for two-stroke engines and four-stroke engine: That is, the piston up and down reciprocating movement of two strokes to complete a work cycle of the engine. Four-stroke engine: where the engine crankshaft every rotation, that is, the piston up and down four-stroke reciprocating movement to complete a work cycle of the engine. Working cycle is the engine by the intake, compression, combustion expansion (work) , exhaust stroke composed of the work process. The process by which an engine completes one intake, compresses, works, and exhausts is called a work cycle, also known as a cycle.

Second, Cheng Chong and four-stroke engine work Principle A, two-stroke engine work principle the piston from the bottom stop to the top stop movement, it will complete the intake and compression process, the first stroke of reciprocating piston motion. The piston moves from the top dead center to the bottom dead center, it will complete the combustion expansion (work) and the exhaust working process, belongs to the piston reciprocating movement second stroke. When the piston moves from bottom to top and all vents and vents are closed, the exhaust and ventilation process is terminated and the fresh combustible mixture in the cylinder will begin to compress. At the same time, as the piston moves up, the capacity of the crankcase under the piston gradually increases, which causes the pressure in the crankcase to drop and forms a vacuum. When the vacuum of the crankcase reaches a certain degree, the reed valve automatically opens, the combustible mixture atomized by the carburetor is sucked into the crankcase. As the piston continues its upward motion, it will be near the TDC when an electric spark from the spark plug ignites the compressed combustible mixture. At this time the burning gas rapidly expand, so that the temperature and pressure of the combustion chamber rise sharply, forcing the piston down movement, piston that is through the connecting rod, crankshaft for useful work. When the piston moves from the top stop to the bottom stop, the pressure in the crankcase will increase with the decrease of the volume, and the reed valve will gradually close automatically. As the piston descends to the vent opening, exhaust gases are discharged into the atmosphere through the vent, the exhaust pipe, and the silencer. When the piston continues down to the vent opening, the precompressed fresh combustible mixture in the crankcase enters the cylinder through the vent and drives the exhaust gas in the cylinder to further discharge, this process is called scavenging. The engine then completes a working cycle. 4-stroke b, principle of four-stroke engine the first stroke -- intake stroke: When the piston is at a specified crank angle just before TDC, the intake valve opens and the combustible mixture is sucked into the cylinder. When the piston moves from the top dead center to the bottom dead center, the exhaust valve closes at a specified crankshaft angle at the top dead center, and the cylinder volume above the piston increases, make the cylinder to form a degree of vacuum mixture to continue through the intake valve intake intake. The intake valve closes when the piston reaches a specified crank angle after the BDC, at which point the intake process is completed. The second stroke-compression stroke: the piston from the bottom stop to the top stop movement, when the intake process is finished, the intake valve and the exhaust valve are closed, this time the cylinder's flammable mixture is compressed. On the compression stroke, when the piston moves up to a specified crank angle before the top dead center, a spark will be generated between the spark plug electrodes, which will be ignited by the compressed combustible mixture. The burning combustible mixture causes the temperature and pressure in the cylinder to rise rapidly, and the piston moves from the top dead center to the bottom dead center under the action of the high temperature and high pressure, and the connecting rod drives the crankshaft to rotate for useful work. The fourth stroke-exhaust stroke: in the combustion expansion stroke, when the piston to the lower stop before a specified crankshaft angle, exhaust valve open, exhaust gas through the exhaust valve began to discharge. The crankshaft continues to rotate and pushes the piston from the bottom to the top. Push the exhaust gas out of the cylinder. This exhaust process is terminated when the exhaust valve is closed at a specified crankshaft angle after the piston line has reached TDC.
