Nghe An 'rescues' prematurely degenerating orange garden
(Baonghean.vn) - From 2018 to now, Nghe An has had over 1,400 hectares of orange trees cut down due to poor quality and early degeneration. Finding the cause, building a standard production process, and replicating successfully "rescued" orange garden models are being implemented by the agricultural sector.
Efficiency from applying standard farming processes
Last year's orange crop, despite the garden being flooded,orange fallAlthough the orange garden of Mr. Phan Trong Bao's family in Dinh Hop hamlet, Dinh Son commune, Anh Son district was affected by the storm circulation combined with the flood discharge from hydroelectric power plants, it still produced 13 tons of fruit, earning 130 million VND, of which nearly 41.5 million VND was net profit, nearly 13.5 million VND higher than the control farmer's orange garden.
“This is something that just a year ago, I would never have dared to dream of. Because after a harvest, the orange garden had yellow wilted leaves, the disease spread very quickly, within just a month, half of the orange garden was affected by this phenomenon” - Mr. Bao said. Frustrated, Mr. Bao decided to cut down the orange trees and switch to growing tea. Luckily, when he had just cut down 13 orange trees, he was advised and guided by a plant protection officer to carry out the care process, saving his family’s 1-hectare orange garden.

Most of the orange varieties grown in the area are grafted by people themselves or bought floating seedlings of unknown origin from Nghia Dan and Quy Hop districts. Improper care, fertilization, and pest control procedures have caused quite serious consequences, with many orange gardens degenerating rapidly.
By early 2021, the total orange area in the province was 4,702 hectares. And from 2018 to now, the area of oranges cut down due to poor growth and development has reached over 1,340 hectares. "Faced with the trend of people massively expanding the area, many production facilities have appeared.orange seed businessrampant, uncontrolled quality of seedlings, especially genetic resources and pests. In the care process, people mainly rely on experience and learn from each other, so they have not implemented it correctly" - Mr. Trinh Thach Lam - Head of Plant Protection Department, Department of Cultivation and Plant Protection of the province is concerned.Replicating effective models
In the province's orientation, in the coming years, citrus trees in general and orange trees in particular will still be one of the main crops, serving domestic demand and aiming for export. It is expected that by 2025, the orange area will reach 6,700 hectares. However, this is a crop that requires high cultivation techniques and investment in care.

“We conducted an investigation to determine the evolution and occurrence of major pests on orange trees in the model area; identified the causes of poor quality oranges, fruit drop, yellow leaves and root rot. At the same time, we applied the basic principles of IPM and ICM to build the model and synchronously applied technical solutions in orange production. From there, we synthesized solutions to transfer to orange growers in the whole province.

From that result, the area of orange trees applying the correct care process has been expanded, many early degenerative orange gardens have been successfully "saved".
