Online biography: seedless grapes hit contraceptive?

Investigation: rumors hurt farmers! A grape cooperative in Chenzhou lost 1.6 million yuan a month.

On September 26, Chenjiawan Village, Liangtian Town, Suxian District, Chenzhou City. It is getting closer and closer to the National Day holiday, which is the peak season for late-ripening seedless grapes, but no one is interested in Zhou Waiqing's grapes. Zhou Waiqing is the director of the Ruixiang fruit and vegetable planting cooperative in Chenzhou. He has planted 200 mu of seedless grapes, ranking first in terms of scale and output. But now, looking at the grapes that are ripe but difficult to sell, Zhou Waiqing is very anxious.

"in the past, the garden was full of people, but now there are pitifully few people. You see, this new variety of 'Sunshine Rose' is on sale in Black September. " The seedless grapes replanted by Zhou Waiqing have been popular in the market in previous years, and they were certified as "green food" in April this year, but the grapes were snubbed by the market when they were listed.

What drove him to the corner of the market was a video that went viral at the end of August: seedless grapes were "planted" with contraceptive. Such news "blew up the pot" among the big grape growers in Hunan. Zhou Waiqing and his colleagues used the "gathering of grapes in Xiangnong" and other "moments" to clarify again and again, but with little effect.

Under the impact of rumors, the sales of seedless grapes, which have always been in the high-end boutique market, have been greatly affected. August and September is the peak of the listing of seedless grapes, and the three main varieties of "Xiahei, Pearl, and Sugarbeet" are the first to encounter unsalable difficulties. Seedless grapes that sold at wholesale prices of 10-12 yuan per jin last year were bargained this year, selling only 5-6 yuan per catty. Not only did the price go down, but sales were blocked, such as the "sugar beet" grapes. In Zhou Waiqing's cooperative alone, more than 160000 jin of the three varieties were removed from the orchard due to unsalable rotten fruit, resulting in a direct economic loss of more than 1.6 million yuan.

Not only the seedless grapes of Ruixiang cooperative, which mainly sells wholesale, but also the seedless grapes of Suyuan cooperative, which is mainly picked on the spot, are also affected. Duan Jinhong, director of the Su Yuan Grape planting Cooperative in Sumutou Village, Aoshang Town, Suxian District, said: "Lanti used to be picked in August, but until the end of August this year, nearly 40,000 jin were rotten in the fruit bag, and only the bag was cut off and thrown away."

Duan Jinhong told reporters that more than 10 members of the club are poor households, who were originally expected to rely on production and marketing of seedless blue to lift themselves out of poverty by the end of the year, but now some members seem not only hopeless to get rid of poverty, but also unable to recover their costs. Poor household Duan Qingxian planted five or six mu of raisins and grapes with an input of 5000 yuan per mu, at least half of which rotted in the field, resulting in a loss of nearly 30, 000 yuan.

"the rotten ones have to be cleaned up, but there are still more than 20 mu of seedless grapes and grapes hanging on the fruit trees. who will help us sell them?" Duan Jinhong and the members are looking forward to it.

Internet biography: eating "seedless grapes grown by contraceptive" will lead to sterilization?

Survey: nonsense! Eating the right amount of plant hormones is safer than eating salt.

How did contraceptive hit the head of seedless grapes?

"Seedless grapes hit contraceptive." Netizens "sun-masked masks" first posted the video on Sina Weibo on Aug. 27. On Aug. 28, the official verified account of Shijiazhuang Information Communication revealed that the video took place in a picking garden near Shijiazhuang and came from "fans". Under public pressure, in early September, the "fan" whistleblower finally confessed that the video was provided by netizens, admitting that "the fruit grower's statement is not entirely true." As for why to send this Weibo, the source claimed in a reply to netizens that he was also skeptical, and was not sure.

But the rumors did not stop abruptly because of this, but flew around like wings. As a last resort, Zhou Waiqing and his colleagues made some textual research on this.

"do you take 'clopirazide' for contraceptive?" This is the analysis of large grape growers. "Clopirazide" sounds like contraceptive, especially in dialects of Chenzhou and other places, the two sometimes sound easy to confuse. Zhou Waiqing listened to some voices in "moments": "Seedless grapes hit clopirazide" sounds like "seedless grapes hit contraceptive", or misspread it through a voice chat on "moments".

"although we use various ways to clarify ourselves, we are outnumbered, and if we prove our innocence again, it will make people feel a bit like every potter praises his pot and boasting." Zhou Waiqing and other big growers are extremely helpless.

"once again, there are such unwarranted rumors, and we must make a clear and positive response to the community, so as not to break the hearts of farmers." In an interview with the reporter, Wu Wuji, president of the grape branch of the Chinese Agricultural Association, said.

Wu Wushi explained that at present, there are two ways to obtain seedless grapes: one is to select grape varieties with degraded seeds by means of genetics and breeding, such as Xiahei grape, and the other is to use gibberellin to seedless grape. so that it can not form seeds, some Jufeng grapes use this method to achieve the goal of seedless.

It is said that because seedless grapes have no seeds, there are no endogenous hormones that promote fruit setting and expansion, resulting in low fruit setting rate and small fruit size, affecting the appearance and quality of seedless grapes. Therefore, in the seedless cultivation of grapes, plant growth regulators such as gibberellin and chloropyruron are often used to achieve the purpose of seedless and large grains, making consumers feel more refreshing.

Contraceptive is an animal hormone and gibberellin is a plant hormone. Can contraceptive work on grapes?

"No matter which plant hormone is used, it is impossible for the human body to grow grapes, and grapes will not become seedless because of the use of animal hormones." Wu Wuji, 74, who has studied grapes all his life, said that grapes have never been found to use animal hormones, and even if they are used, they do not work for grapes. He believes that for hormones to work, there must be target organs, plant hormones are ineffective to the human body, and animal hormones are not useful to plants, because there are no corresponding targets.

So, is there a limit on gibberellin in grape production? Will overuse affect grapes and the human body?

Li Xianxin, a researcher and deputy director of the Institute of Horticulture of the Hunan Academy of Agricultural Sciences, told reporters that the concentration standards of gibberellin required by different fruits and vegetables are different, and the concentration of gibberellin in grapes had better be in the range of 20-25ppm, that is, it is more reasonable to use one gram of gibberellin dissolved in 80-100jin of water.

"growers generally do not deliberately overuse gibberellin in terms of cost and benefit. But it does not rule out that some farmers lack scientific common sense and add too much gibberellin to the grapes. " Yang Guoshun, post scientist of the national grape industry technology system and dean of the School of Horticulture and Landscape Architecture of Hunan Agricultural University, said.

"if gibberellin is used too much, seedless grapes will be shredded, cracked and deformed. In the process of production, the fruit will be burnt out and fall into the ground, making it impossible to sell at all." Duan Jinhong said that farmers will add an appropriate amount of gibberellin in accordance with expert guidance and factory instructions.

So, will it be harmful to human health if we eat seedless grapes with gibberellin?

Li Xianxin said that studies have shown that an adult weighing 120jin needs 180mg of gibberellin a day to have side effects on the human body. According to the results of the Ministry of Agriculture's grape quality and safety risk assessment, the residue in the detected sample is no more than 0.1mg / kg, that is to say, an adult needs to eat at least 1800 kg of grapes a day to have an impact on his body.

"rational use of gibberellin and other plant growth regulators is not only good for improving the quality of grapes, but also safe for the human body. In terms of chemical toxicity, the toxicity of appropriate amounts of plant hormones is very low, which is safer than the salt and glucose we eat." He said without a disease.
