There are frequent ups and downs in the supply and demand of agricultural products in the mainland.

Mao Yugui, a 60-year-old vegetable farmer in Lanzhou, lost all four acres of cauliflower planted this year. The drop in the price of cauliflower on the market for nearly a month hurt the old man: since mid-July, cauliflower has fallen from 1 yuan per jin to 10 cents or 5 cents. No one even cared about it, and eventually had to dump or feed the livestock.

At present, it is the harvest time of "plateau summer food" in Gansu, which supplies more than 80 large and medium-sized cities in the mainland. In the vast mountains of Yuzhong County, Lanzhou, cauliflower and leaves can be seen withered and rotten in the vegetable field everywhere. Some vegetable farmers collect these in time and dump them to make room for other vegetables. Some vegetable farmers simply beckoned the surrounding sheep to come to help clean up.

"Last year, when the price of cauliflower was at its best, it reached NT $3 or 4 per jin, and the average yield per mu was 6,000 jin." In Mao Yugui's view, many vegetable farmers have benefited from the "good price" of cauliflower last year, which has greatly expanded the planting area of cauliflower here this year, but local buyers simply cannot "digest" so much.

In order to grab the delivery time, Mao Yugui and his family recently had to go to the field at 3: 00 a. M. to pick cauliflower and then send it to a vegetable exchange a few kilometers away. "if you go late, the shopping car will be full." Mao Yugui said that through "rescue," the cauliflower in the field has basically been sold, but the income per mu is only about 1,000 yuan, which is not even enough for seed, pesticide, chemical fertilizer and labor input.

"growing cauliflower has only met this time in the past ten years, and it has never been so miserable." Li Sharon, a 62-year-old vegetable farmer, had no choice but to watch the sheep eat after selling some of the better cauliflower at a low price. Although he is planting baby vegetables in the fields in the past two days, he is not so sure in the face of erratic market demand. "We just want to grow other vegetables to make up for the losses, but it is not clear whether we will be able to enter the market in the future."

In recent years, due to the lack of information on supply and demand in the market, the prices of agricultural products in the mainland, including vegetables, have frequently experienced sharp ups and downs. From "garlic you are ruthless" to "garlic you are cheap", from "Jiang your army" to "Jiang Bureau", the rising and falling prices of agricultural products not only make farmers feel uneasy on this side, but also express their dissatisfaction and helplessness in the way of ridicule. In addition, wholesalers in the middle also complain incessantly.

Luo Lianfu, a vegetable merchant in Lanzhou, has long been engaged in reselling Gansu summer food to Beijing, Xi'an and other places. "Farmers in Gansu, Shandong, Hebei and other places are planting cauliflower blindly this year." He, who has 18 years of experience in market supply and demand, said that this has led to generally low prices in various places, and some are even unsalable. At this time, exporting cauliflower will usually lose money, but if you don't continue, you will lose your position in the vegetable market in other places, and you will have to stick to it even if you lose money.

"supply and demand information is not smooth, planting 'crash' is the main reason for the sharp drop in cauliflower prices," Kou Mingke, director of the Agricultural products Marketing Management Office of Gansu Province, analyzed to China News Service on the 13th. Vegetable planting income is good in the past two years. Many farmers in the mainland are "following the trend" to grow, especially for vegetables with strong market demand in a short period of time, the information of vegetable farmers often lags behind the changes in the market. As a result, vegetable prices plummeted or soared.

According to official statistics, as a vegetable production, supply and wholesale distribution center in northwest China, Gansu supplies more than 10 varieties and about 4.5 million tons of vegetables to more than 20 provincial capitals in the south from May to October every year. In addition, it is also exported to South Korea, Japan, Southeast Asia and Hong Kong, Macao and Taiwan.

Kou Mingke said that in order to avoid the risk of "car crashes" caused by poor supply and demand information, Gansu has increased the construction of vegetable cold stores in recent years to regulate market supply and demand, while relying on local market information fed back by more than 300 foreign vegetable buyers every year. Judging from the situation in recent years, the planting risk of farmers has been significantly reduced.
