From “losing money to marry off a daughter” in the past to turning waste into treasure today文章源自FOFCC-http://fofcc.org.cn/am/11291/
In March, as the waters warm, a surge of spring plowing sweeps in. Recently, reporters learned from an investigation in Jiangxia District that more and more farmers are willing to apply organic fertilizer.文章源自FOFCC-http://fofcc.org.cn/am/11291/
Yesterday, in Laoshi Village, Zhengdian Street, Jiangxia District, three transport vehicles were delivering dark biogas slurry to greenhouses. Villager Cao Qiulian said that everyone is buying organic fertilizer, and the village has purchased at least more than 1,000 tons in the past month or so. “In previous years, pig manure had to be hauled away at one's own expense, and even when given away for free, one still had to speak nicely to people; now, many farmers are willing to take the initiative to bear the transport costs, and sometimes it can even sell for 20 to 30 yuan per ton.” Yang Jie, head of the Jiangxia Xianqiao Pig Farm, said, “This situation is similar at more than 40 large pig farms across the district.”文章源自FOFCC-http://fofcc.org.cn/am/11291/
Even more sought after than pig manure is chicken manure. Xu Hong, chairman of the Wuhan Gangfa Poultry Farming Professional Cooperative, introduced that the cooperative's 200 farming households collect about 10,000 tons of chicken manure each year, and there is no worry about finding a market for it. The price per ton has even risen from 130 yuan last year to 200 yuan, becoming a new channel for farming households to increase income.文章源自FOFCC-http://fofcc.org.cn/am/11291/
According to statistics from the district's agricultural department, since this year's Spring Festival, major farms across the district have sold more than 50,000 tons of biogas fertilizer and dried pig and chicken manure, twice that of the same period last year and more than five times the amount three years ago.文章源自FOFCC-http://fofcc.org.cn/am/11291/
Chemical fertilizers are gradually “no longer running the show”文章源自FOFCC-http://fofcc.org.cn/am/11291/
Behind the strong sales of organic fertilizer, what is the secret?文章源自FOFCC-http://fofcc.org.cn/am/11291/
Wang Zuoxiang, chief agronomist of the Jiangxia District Agriculture Bureau, believes that this reflects that farmers have begun to change their production concepts and are gradually bidding farewell to the era of “chemical fertilizers running the show.”文章源自FOFCC-http://fofcc.org.cn/am/11291/
At present, bagged organic fertilizer on the Jiangxia market costs more than 800 yuan per ton, while chemical fertilizer costs more than 2,000 yuan per ton. Calculated on the basis that each ton of organic fertilizer covers 2 mu of land and each ton of chemical fertilizer covers 10 mu of land, the input cost of organic fertilizer is relatively high.文章源自FOFCC-http://fofcc.org.cn/am/11291/
But for ordinary vegetables, using only chemical fertilizers yields about 1,000 kilograms per mu, while using organic fertilizer can reach 2,000 kilograms per mu. For rice, adding organic fertilizer can increase yield by 20% to 30% per mu; if relying on chemical fertilizers year after year, it will lead to soil acidification, water and soil pollution, and yields will not increase but instead decline.文章源自FOFCC-http://fofcc.org.cn/am/11291/
In earlier years, Jinkou Street once planted garlic on a large scale. Some farmers were accustomed to using more urea, but year after year, the organic matter and trace elements in the soil became increasingly scarce. The garlic leaves grew yellower and yellower, and the garlic bulbs grew smaller and smaller. When farmers in Tudi Tang grew watermelons, some liked to use more chemical fertilizer, which resulted in soil compaction and actually produced “iron watermelons,” with rinds about one cun thick.文章源自FOFCC-http://fofcc.org.cn/am/11291/
Wang Zuoxiang said that many years of farming practice have gradually made farmers realize that excessive use of chemical fertilizers is ultimately not a long-term solution. He gave an example, saying that people today no longer eat indiscriminately. For the sake of health, they pay attention to “organic” and “pollution-free” when eating food. Crops also have life; how can they eat “rich meat dishes” all year round? Organic fertilizer is precisely the “organic food” for soil and crops, and its popularity should be a natural choice of the agricultural ecological chain.文章源自FOFCC-http://fofcc.org.cn/am/11291/
Data show that in recent years, the total grain output of Jiangxia District has increased year by year, and the total vegetable output has remained basically stable, but the total amount of chemical fertilizer used, after peaking in 2007, has declined year by year from 97,000 tons to 82,000 tons last year.文章源自FOFCC-http://fofcc.org.cn/am/11291/
Sweet vegetables, fragrant rice, and warmer wallets文章源自FOFCC-http://fofcc.org.cn/am/11291/
“Relying on chemical fertilizers to grow lotus roots, the yield is 2,000 kilograms per mu, and after being dug out they can be stored for half a month; using organic fertilizer to grow lotus roots, the yield is 3,000 kilograms per mu, and after being stored for a month they are still very fresh,” said Hu Tao, general manager of Yishanwan Ecological Agriculture Co., Ltd. in Fasi Town, unable to contain his joy. The lotus roots grown by the company using organic fertilizers such as biogas slurry have been exported to Canada.文章源自FOFCC-http://fofcc.org.cn/am/11291/
Wang Zuoxiang introduced that vegetables and rice grown with organic fertilizer are relatively sweeter and more fragrant. For example, the Hongshan caitai grown with organic fertilizer in Laoshi Village is sweeter and crisper than ordinary caitai. Last year's warm winter caused Wuhan's caitai to grow wildly. In many places, caitai were sold cheaply for one mao and still found no buyers, but the caitai from this village were highly favored by consumers. In addition, the more than 1,000-mu organic rice base built by Guizi Rice Industry Company uses all organic fertilizer, and the rice it produces has been gaining an increasingly strong reputation and is in short supply.文章源自FOFCC-http://fofcc.org.cn/am/11291/
The high yield and high quality brought by organic fertilizer have provided support for increasing farmers' income. Last year, Jiangxia District planted 660,000 mu of rice, and the use of organic fertilizer accounted for 30% of the total fertilizer amount; among the 230,000 mu of vegetables newly sown this spring, the promoted area of organic fertilizer has already reached more than 100,000 mu. Since 2007, the district's per capita net income of farmers has increased from 5,386 yuan to 8,317 yuan last year.文章源自FOFCC-http://fofcc.org.cn/am/11291/
