Female doctors developed the world's first organic litchi

Organic litchi production is currently a problem in the production of organic food in the world. In the production process, chemical pesticides and chemical fertilizers cannot be used, but they must also be supplemented with advanced pest ecological control methods. The technical requirements are high. Under the guidance of Prof. Liang Guangwen from South China Agricultural University, Dr. Ji Jidong began to work in 2002 with the support of the local government and relevant personnel. He used Yangchunchun Bay, an ecological environment, as the organic litchi test base. Litchi, related technologies passed the provincial appraisal in June of this year. In midsummer of June, it was also a time of great admiration. The good news came from Yangchun City, Guangdong: The organic litchi production technology, led by Liang Guangwen, a professor at South China Agricultural University, and his female disciple, Dr. Ji Jidong, passed the provincial appraisal in one fell swoop. This indicates that the large-scale organic production of Litchi in our province may become a reality, and the export of Guangdong litchi will also face a revolutionary turnaround. The use of chemical fertilizers causes poor export. As we all know, litchi is a “fist” fruit in southern China, especially in Guangdong. China's litchi output accounts for 80% of the world's total, while Guangdong accounts for about 60% of the country's total output. Although Lingnan Litchi is a famous brand of fruit with the greatest export potential, it has not been satisfactory in recent years. The most important reason is that some places are over-reliant on chemical pesticides and chemical fertilizers, resulting in unsatisfactory indicators for some ingredients. Directly affected exports. Therefore, the issue of organic lychee production has been raised, namely whether it is possible to produce a natural, pollution-free, safe and nutritious lychee without using any synthetic fertilizers, pesticides and growth regulators. Two-year problem solving and solving problems to solve this problem is Dr. Qi Jidong and related personnel under the guidance of Prof. Liang Guangwen. Recently, in the Chunjiang Ecological Orchard, Sui Jidong and the owner of the orchard Zhong Siqiang, Zhong Jianchao and his father and son, pleased the reporter visited the Organic Litchi Garden. Ji Jidong enthusiastically told reporters: "It was a good coincidence. In the June 1st Festival in 2002, my friend Zhong Jianchao brought me the "Guiwei" lychee planted in his family. Let me think of ways to look at it. He can't let the lychees he has worked so hard to sell at a good price.Because I happen to be engaged in organic food research, if I can produce organic lychees, I might have good prospects. When I told Zhong Jianchao the idea, he accepted it with pleasure. So at the end of 2002, I started experimenting in his orchard. After nearly two years of research, I finally got this result." Market sales are expected to increase drastically. Dr. and related personnel will use non-chemically synthesized green manure and compost. The promotion of litchi fruiting and growth, combined with ecological control techniques such as insect repellent, insect repellent natural enemy, manual weeding, etc., make the litchi fruit has the advantages of clear, fragrant, sweet, brittle, etc., the taste is better than the general litchi, the fruit rate is reduced to Below 2%, it is much lower than the standard rate of 5% of the common lychee fruit. On June 6 last year, Chunjiang Ecological Garden in Chunwan Town, Yangchun City harvested the world's first organic litchi. In the year, 50 acres of organic "Guwei flavor" lychee cultivated by the orchard produced more than 3,500 kilograms and was sold immediately after being shipped to Guangzhou, Zhuhai, Hong Kong, and Macau. The price per kilogram was as high as 60 yuan. A year later, after the review of experts from relevant scientific research institutes and institutions of higher learning in Beijing and Guangzhou, the organic litchi production technology finally passed the provincial appraisal. Dr. Yan told reporters that after successful organic litchi test seeding, many exporters came to contact with exports. To be sure, the market demand will be very large. She and Professor Liang will vigorously promote organic lychees in Yangchun and other places, and strive to export organic lychees to the United States next year.
